The present disclosure generally relates to configuring a wireless network. More specifically, the present disclosure relates to increasing the efficiency of setting up a wireless network.
Every day the use of wireless networks is expanding. Furthermore, various different vendors provide redundant wireless links that allow wireless data communications to be switched between different pieces of computer hardware as needed. Communications may initially be passed via a first wireless access point and those communications may switch to being passed via a second wireless access point when the first wireless access point fails or when that first wireless access point becomes heavily loaded. In other instances, communications may be switched from the first to the second wireless access point when a mobile device is moved from one place to another. Wireless mesh networks predominantly use communications consistent with one of the 802.11 (or “Wi-Fi”) wireless communication standards. Because of this, 802.11 communication channels are a preferred type of communication channel used in wireless mesh networks.
Today, a number of wireless access points or nodes in a wireless network may vary significantly. For example, a first wireless network may include two wireless access points and a second wireless network may include dozens of wireless access points. Wireless networks configured to switch communication traffic between different wireless access points are commonly referred to as wireless mesh networks, where individual access points may be referred to as mesh nodes, mesh points, or mesh portals. The ability for switching communication traffic allows hubs, routers, or switches included in conventional wired networks to be bypassed as each individual mesh node may perform functions consistent with a legacy hub, router, or switch.
Processes for setting up and configuring a wireless mesh network are often time consuming, inefficient, error prone, insecure, or are not scale-able. In certain instances, once a wireless mesh network is setup, adding additional wireless access points to that network may not be possible, in other instances adding additional wireless access points may require an administrator to manually configure new mesh nodes using tedious processes.
One process for setting up wireless access points relies on initially connecting a network cable (such as an Ethernet cable) to each respective access point as each of those respective access points are configured in a serial fashion. Such a serial setup methodology does not scale well as the setting up of 10 mesh nodes takes 10 times longer than setting up a single mesh node.
A second process that may be employed to setup wireless mesh networks is to configure a fixed number of wireless access points when those access points are manufactured. Once this fixed number of access points are factory configured to securely communicate with each other, they can be installed and operate in a configuration that may not be expandable. While this second process has the advantage of easy secure installation, it suffers with scale-ability limitations. As such, this second configuration process may be appropriate for smaller mesh networks where there may be no need for the size of that mesh network to increase over time.
A third process that may be used to setup a wireless mesh network is by using non-secure wireless data communications to initially configure wireless access points. While this third process may provide the ability for a wireless mesh network to be expanded, every time a wireless access point is initially configured, data being communicated wirelessly during that configuration process may be observed or exploited by individuals with nefarious intent. This provides a window of vulnerability that exposes a network to being attacked. For example, a hacker could pretend to be a new access point or could pretend to be a device attempting to connect to the wireless network using information that was observed (snooped) by the hacker during the window of vulnerability.
In certain instances, vendors that provide mesh device rely on the use of onboarding service web portal to setup a wireless mesh network. Such instances may require that a user can login and manually input the access point device serial numbers to complete the registration process. This manual process is error-prone and requires users to spend a large amount of time collecting device information and entering that information into a web portal one by one. This is a lengthy process that is very tedious, especially when a large wireless network is configured. In other instances, other products may be installed using a batch processing solution that may help reduce manual effort to some extent, yet even such batch processing methods still require a person to enter data manually as part of the configuration process. An example of a batch process is where a user enters data into an Excel spreadsheet that is later used with a software program that accesses the spreadsheet during the network setup process. Such batch processing techniques, however still requires error-prone manual data entry and additional effort may be required to maintain the excel spreadsheet over time.
Since, current wireless access points are not designed to easily be installed, provisioned with software, or configured in a secure way, what are needed are new ways of securely installing, provisioning, and configuring wireless access points and other devices that communicate with a wireless mesh network.
The presently claimed invention relates to a method, a non-transitory computer readable storage medium, and an apparatus executing functions consistent with the present disclosure for setting up wireless mesh network devices. A method consistent with the present disclosure may include organizing information associated with a set of wireless devices and that generates a profile for configuring the set of wireless devices into a new wireless mesh network. The profile may have been generated according to inputs received by a computing device. After the profile has been generated, registration information may be sent to another computer. This registration information may identify the computing device and each individual wireless device of the set of wireless devices. After the registration information is received by the other computer, a message may be received from the computer that indicates that the new mesh network has been registered as a registered mesh network.
When the method of the presently claimed invention is implemented as a non-transitory computer readable storage medium, a processor executing instructions out of a memory may implement a method consistent with the present disclosure. Here again this method may include organizing information associated with a set of wireless devices and that generates a profile for configuring the set of wireless devices into a new wireless mesh network. The profile may have been generated according to inputs received by the processor at a computing device. After the profile has been generated, registration information may be sent to another computer. This registration information may identify the computing device and each individual wireless device of the set of wireless devices. After the registration information is received by the other computer, a message may be received from the computer that indicates that the new mesh network has been registered as a registered mesh network.
An apparatus consistent with the present disclosure may include a memory and a processor that executes instructions out of the memory to implement methods consistent with the present disclosure. Here again this method may include organizing information associated with a set of wireless devices and that generates a profile for configuring the set of wireless devices into a new wireless mesh network. The profile may have been generated according to received inputs. After the profile has been generated, registration information may be sent to a computer that stores mesh network registration information. This registration information may include an identifier that identifies a computer that is associated with the processor and may include information that identifies each individual wireless device of the set of wireless devices. After the registration information is received by the computer, a message may be received from the computer that indicates that the new mesh network has been registered as a registered mesh network.
The present disclosure relates to securely setting up mesh networks in a manner that does not require a physical network cable being attached to a wireless mesh device and that does not require transmitting unencrypted information wirelessly when a mesh network is setup. Methods and apparatus consistent with the present disclosure may allow a user to choose which mesh nodes can join a network and that user may specificity a custom profile that may include rules that may identify how mesh network identifiers (IDs) are used, that identify passcodes/passphrases assigned to a particular network, may identify types of traffic that may be passed through particular 802.11 radio channels, or other parameters that may control how traffic is switched between devices in a particular wireless mesh network. This combined with dual factor verification and the use of different types of communication channels make wireless mesh networks easy to deploy and expand according to the wishes of users that are responsible for establishing and maintaining specific wireless mesh networks.
In certain instances mesh portals consistent with the present disclosure may wirelessly communicate with a plurality of wireless mesh points and may communicate over a wired network. As such, a mesh portal may be act as a gateway between wireless mesh points and a wired local area network, for example. In such instances a mesh portal may broadcast transmissions that include a mesh identifier (MSSID) and a cluster name that advertise the wireless network to mesh points that are configured to operate as members of a particular wireless mesh network. In other instances, a mesh point may include a cellular (e.g. 3G, 4G, LTE, or 5G) link or more than one mesh node in a mesh network may be configured to operate as a redundant mesh point that uses a wired or a wireless network connection.
The terms “access point” or “wireless access point” in the present disclosure refer to a device that may be wirelessly communicatively coupled to a computer directly without wireless communications passing through another wireless device. As such, the terms “access point” or “wireless access point” may refer to either a mesh portal or mesh point, the terms mesh portal relates to a wireless device that performs functions that a mesh point need not perform. Both mesh portals and a mesh points may perform functions consistent with a wireless access point because both mesh portals and mesh points may act as a wireless access point that directly wirelessly communicates with a computer in just a single hop, without wireless communications passing through another wireless device. The terms mesh node in the present disclosure may be used to refer to either a mesh portal or a mesh point that uses wireless communications to transmit and receive wireless computer network messages and data.
Typically the terms “firewall” or “gateway” in the present disclosure refer to computing devices that communicate over wired network connections. In certain instances, however, a mesh node may include functionality consistent with a firewall or gateway. In certain instances, functions conventionally associated with a firewall or gateway may be performed by a mesh portal or by mesh point. In these instances, a mesh portal or a mesh point may perform functions consistent with evaluating content ratings, deep packet inspection, or may include anti-virus program code.
A mesh portal will transmit and receive data network communication traffic between two different types of computer network, for example, between a network that communicates over wires and a network that uses wireless 802.11 signals. Alternatively or additionally, a mesh portal may transmit and receive data network communication traffic between a cellular network and an 802.11 network. Mesh points, however, may be limited to receiving and transmitting network traffic wirelessly over a single type of network, for example, over an 802.11 network. While mesh portals include different functionality as compared to a mesh point, certain mesh points may be configured to assume the role of a mesh portal.
Once configured, mesh points consistent with the present disclosure may communicate using wireless 802.11 communications only, or some of these mesh points may be configurable to be promoted to assume the functionality of a wireless mesh portal. While communications in a mesh network may be sent through any number of mesh points until those communications reach a mesh portal, most mesh points may typically be located within three hops of a mesh portal. Furthermore, a number of mesh portals that communicate with a mesh point may be limited by a setting
For example, a rule may limit a number of mesh portals connected to a particular mesh portal to eight or another rule may limit a number of hops to three.
The mesh point portals (140B & 150B), mesh points (140 C/D & 150 C/D) of
Computing devices connecting to a particular mesh network and mesh nodes (mesh points or mesh portals) may be setup and configured using methods that increase security by using shared secrets or that use privileged communication pathways. These shared secrets or privileged communication pathways may be difficult or impossible to observe (snoop) or hack. For example, a particular computing device may be configured to communicate with cloud management system 110 of
Processes for configuring and setting up devices in a wireless mesh network may also include two factor authentications, where secret information is sent to a user device. For example, a message that includes secret information may be sent to an email address or may be sent in the form of a text message to the user device. This secret information may then be used to secretly validate or identify that the computing device can be allowed access communicate with devices at a wireless mesh network. For example, a user device may provide a secret code that was received via a text message from a computer located at the cloud or Internet to a wireless access point.
Once validated, a user device may be able to connect to a particular mesh network from anywhere. For example, a configuration at a validated user device may allow that user device to connect to the mesh network via a cellular connection when that user device is located at a location far from an 802.11 mesh network. In such an instance, the user device may communicate with other devices that are located within a zone, where these other devices may communicate via the mesh network using communications consistent with an 801.22 WI-FI communication channel.
When a mesh network is configured, communications may pass from one or more mesh nodes (mesh point or mesh portals) as those mesh nodes are provisioned with software or configured using onboarding service 130 of
Whenever mesh nodes in a mesh network are powered on (boot up) they may communicate with each other when identifying best pathways that can be used to pass network communications. In certain instances, different frequencies may be used to transmit 802.11 communications and these frequencies may be configured by one or more rules that direct certain types of communication traffic to a particular radio frequency. For example, communications that use 5 gigahertz (GHz) signals may be used to transfer network associated data and client traffic and communications that use 2.4 GHz signals may be used only for client data. Furthermore, each mesh node (mesh point or mesh portal) may be configured and provisioned according to a consistent profile according to one or more rules.
Initially, program code of mobile APP 200 may prepare a message 212 to send to an onboarding service in the cloud. This communication may be passed by any communication medium known in the art, yet for convenience, in certain instances, message 212 may be sent via a wireless cellular communication link. Message 212 will typically be sent via a secure communication protocol, such as the secure hyper-text transfer protocol (HTTPS). By using a secure communication protocol information may be securely provided to a cloud computer that executes program code consistent with onboarding service 209. In certain instances, message 212 may be passed through host 206. Alternatively, message 212 may be passed directly to the computer executing the instructions of onboarding service 209 without passing through host 206. Message 212 may include a user identifier (UID), a password, and a security key. After the login information has been sent to onboarding service 209, the computer executing the onboarding service 209 program code may include instructions that cause a unique session token to be sent to a mobile device executing instructions associated with mobile APP 200. Program code associated with onboarding service 209 may also use a two-factor authentication process to validate a user device before issuing a session token. For example, a cloud computing device may send a text message, email, or voice message that includes a code that must be provided to the cloud computer before a session token is sent to a mobile device in communication 215 of
In certain instances, BLE link 203 may be coupled to a first processor at a wireless access point that communicates with a second processor at host 206. Because of this the first processor at the wireless access point may perform tasks associated with messages or processes 218, 221, 224, 227, 230, 233, 236, 239, 245, 248, 251, 266, 269, 272, and 275 and the second processor at the wireless access point may perform tasks associated with messages or processes 218, 221, 248, 251, 269, and 272. In other instances, other low power data communication technologies may be used in when a wireless mesh network is setup. For example, a proprietary wireless communication technique may be used or a high bandwidth short distance millimeter radio wave transducers (such as transducers made by Keyssa (e.g. the “Keyssa Kiss”) or optical data transmitters/receivers/transceivers may be used.
A person configuring their wireless mesh network may then use their mobile device to scan a barcode, a quick response (QR) code, or a near field data communication (NFC) tag to obtain information associated with host 206. After the mobile user device has scanned code or tag, authentication information may be sent via short distance wireless link 203 to host 206 in communication 218 of
Host computer 206 may then broadcast advertisement messages to devices within range of the low power link 203. This advertisement may be in a format consistent with a low power Bluetooth advertisement that may include an encoded universal unit identifier (UUID) and this encrypted UUID may include an authorization code, a system status, and a serial number, for example. The mobile APP 200 at a mobile device may then compose a connect message 227 that is sent to host computer 203 via link 203, and a Bluetooth connection message 230 may then be sent to the mobile device when a secure low power/Bluetooth communication session is established between the host 206 and the mobile device. After the low power communication session has been established, mobile APP may then generate request message 233 to send to the host 206 of
Host 206 may then generate message 239 that includes a machine integrity code (MIC) and the second nonce. After message 239 is generated it may be sent to the mobile device. Next, mobile APP 200 may then extract the MIC and the second nonce from message 239 and then a processor at the mobile device may generate the pairwise temporary key using information that may include the first nonce, the second nonce, the mobile device MAC, the host MAC, the serial number, the authentication code, or other information in process 242 of
The cloud computer executing the instructions consistent with onboarding service 209 may then validate the mobile device during process 260 that may check that the user device is associated with a valid license or valid customer account. In certain instances, the cloud computer may store information that associates host 206 and the user device MAC with a particular wireless mesh network and with a particular customer. After the mobile device is authenticated, onboarding service 209 may then prepare a message to send to the mobile device and the cloud computer may then send a registration complete message 263 to the mobile device.
After receiving the registration complete message, the mobile application 200 at the mobile device may then send an encrypted message 266 via wireless link 203. This encrypted message may include an encrypted version of the pairwise temporary key that was calculated during process 242 of
After completing this configuration process, the mobile device executing program code consistent with mobile APP 200 may securely communicate with computing devices at the Internet via one or more different mesh nodes devices included in the newly configured mesh network. Host 206 may be a mesh point or a mesh point portal like those illustrated in
Methods and apparatus consistent with the present disclosure may allow a user to choose which mesh nodes can join a network and that user may specificity a custom profile that may include rules that may identify how mesh network identifiers (IDs) are used, that identify passcodes/passphrases assigned to a particular network, may identify types of traffic that may be passed through particular 802.11 radio channels, or other parameters that may control how traffic is switched between devices in a particular wireless mesh network. This combined with dual factor verification and the use of low power wireless communication channels make methods and apparatus consistent with the present disclosure easy to deploy and expand according to the wishes of users that are responsible for establishing and maintaining specific wireless mesh networks. In certain instances, mesh IDs and passcodes/passphrases may be based on a timestamp or equipment identifiers that insure that a mesh ID or other information are unique. Methods consistent with the present disclosure may receive settings or profile information via operation of a program application, like mobile APP 200 of
Once the code is acquired, user device 310 may communicate with the wireless access point when a wireless mesh network is setup, provisioned, or configured. A program application executing at user device 310 may allow user device 310 to identify a serial number and authentication code associated with the wireless access point when sending communications to that wireless access point as illustrated in communications 218, 221, 224, 227, 230, and 233 of
For example, user device 310 may have been used to configure mesh nodes at an office in San Francisco that is associated with customer A. In an instance, where a user of user device 310 travels to an office of customer A in Los Angeles, user device 310 may be identified as being authorized to access the wireless 802.11 network of customer A at their Los Angeles office. Alternatively or additionally, user device 310 could access other devices at the wireless mesh network via a cellular communication interface, when user device 310 was located away from either the San Francisco or the Los Angeles office of customer A.
During installation of a new wireless mesh network or when expanding a wireless mesh network, all nearby compatible wireless mesh devices may be identified along with respective capabilities of each respective wireless mesh device. In certain instances, a user may be able to select from a list of mesh devices identified using low power data communications when the mesh network is setup or expanded and each of the selected mesh devices may be configured according to a profile in a parallel rather than in a serial manner. The scanning capability illustrated in respect to
The mesh point 435 of
Mesh portal 460 includes processor/CPU 465 that may execute instruction out of memory 470. Mesh portal 460 also includes communication interfaces of low power Bluetooth light interface 475, Wi-Fi 802.11 interface 480, and cellular interface 485. Note that mesh portal 460 includes cellular communication interface 485, where mesh point 435 does not include a cellular communication interface. Items 460 are communication connections 460C that CPU 465 may use to access memory 470 or that CPU 465 may use to communicate with low power Bluetooth light interface 475, Wi-Fi 802.11 interface 480, and cellular interface 485. Communication connections 460C may include direct electrical connections that form a communication bus. Mesh portal 460 may implement functions consistent with the various mesh portals (140BC or 150B) discussed in respect to
Note that mesh portals and mesh points may include different capabilities as mesh portals may include functionality that allows the mesh portal to send network communications over cellular communication interface 485, where mesh point 435 may not include this functionality. In certain instances mesh portals may include wired network interfaces that allow a mesh portal, like mesh portal 460 to send network communications over a wired computer network, where mesh point 435 may not include such functionality.
Alternatively, mesh point 435 may include a cellular communication interface or a wired that is disabled based on a mesh point configuration that is different from a mesh portal configuration. In certain instances, user device 405 may communicate with both mesh point 435 and with mesh portal 460 using a low power signals that have a limited range. For example Bluetooth light interface 420 at mobile device 405 may communicate with mesh point 435 using Bluetooth light interface 450 and may communication with mesh point 460 via Bluetooth light interface 475 during a registration process. User device 405 may also communicate with mesh point 435 using 802.11 interface 425 at user device 405 and 802.11 interface 455 at mesh point 435. Alternatively or additionally, user device 405 may also communicate with mesh portal 460 using 802.11 interface 425 at user device 405 and 802.11 interface 480 at mesh portal 460.
In an instance where mesh point 435 fails when user device 405 is communicating with mesh point 435 over using communications consistent with the 802.11 specification, communications could “fail over” (switch) to mesh portal 460 or another mesh point (not illustrated in
In certain instances, methods and systems consistent with the present disclosure may include promoting a mesh point to assume functions of a mesh portal. This may occur when a particular mesh portal fails, when a greater than a threshold error rate is encountered, when an increased collision rate associated is observed, or when a measure of congestion associated with a mesh portal reaches a threshold level. The promotion of a mesh point to a mesh portal may include enabling functionality at a particular mesh point. For example, in an instance when mesh point 435 is promoted, a cellular communication interface at mesh point 435 may be turned on (enabled) such that mesh point 435 could assume duties previously performed by mesh portal 460.
Cloud management system 510 of
Processor 520 may execute instructions out of memory 530 when operations consistent with management console 540 are performed, when information is stored in database 560, when operations consistent with onboarding service 550 are performed, or when communications are transmitted/received via network interface 570. Operations consistent with onboarding service 550 may include the same sorts of operations discussed in respect to onboarding service 209 of
The information organized in step 610 of
The user/administrator may then provide inputs or settings that may be used to generate a profile for configuring the wireless devices into a wireless mesh network in step 620 of
After the user computing device has generated the profile, registration information may be sent to a computer in the cloud in step 630 of
After the registration information has been sent to the cloud computer, the cloud computer may review that information and a message may be received from the cloud computer in step 640 that indicates that the registration process of the devices in the new wireless mesh network has been completed. The cloud computer may store this registration information under a customer identifier and this information may be used by the cloud computer at a future time.
After the registration has been completed in step 640 of
After the new mesh network has been registered and configured, each of the mesh points or mesh portals may send communications using the 802.11 protocol according to the profile generated in step 620 of
At a later point in time when there is a need to expand the wireless mesh network to include more wireless mesh points or mesh portals, the user computing device may once again scan a label, bar code, QR code, or NFC code associated with a new wireless access point. At this point in time, the user computing device may communicate with the new wireless access point using the low power communication interface and the user computing device may share the previously stored configuration information with the new wireless access point as that wireless access point is prepped to join the wireless mesh network registered in step 630 of
