The detailed description will be better understood in conjunction with the accompanying drawings as follows:
The present embodiments are detailed below with reference to the listed Figures.
Before explaining the present apparatus in detail, it is to be understood that the apparatus is not limited to the particular embodiments and that it can be practiced or carried out in various ways.
The present embodiments generally relate to a router configured to monitor network traffic on a home network and a personal device configured to communicate with the router to control the network traffic.
The router configured to monitor the network traffic on a home network can include computer instructions for detecting the presence of a device on a wired and wireless local area network. The router configured to monitor the network traffic on a home network can also include computer instructions for capturing an Internet Protocol (IP) address and Media Access Control (MAC) address for the device on the local area network. The router configured to monitor the network traffic on a home network can include computer instructions for tracking and monitoring changes to IP addresses for the device. The computer instructions for tracking and monitoring changes to IP addresses for the device can instruct the processor to detect the current state of the Address Resolution Protocol (ARP) table, compare to a previous ARP table state and the Dynamic Host Configuration Protocol (DHCP) lease file to determine changes to IP addresses for the device.
The computer instructions for detecting the presence of a device on a wired and wireless local area network, the computer instructions for capturing an IP address and MAC address for the device on the local area network, and the computer instructions for tracking and monitoring changes to IP addresses for the device can work with one another to instruct a processor of the router to monitor an ARP table. The ARP table state is examined to determine changes in the client device set. For example, the ARP table can be examined to detect new MAC addresses, which are new devices. If two entries (with different IPs) appear for the same MAC, checking against the previous ARP sample can determine which IP address is the new IP address in the event of an address change. If there is no previous sample (at turn on or restart) the DHCP lease file is examined for a tip. If DHCP isn't assigning addresses automatically due to a failure, then the processor can be instructed to wait for the old entry to age out.
The router configured to monitor the network traffic on a home network can include computer instructions for extracting a host name associated with the device.
The computer instructions for extracting a host name associated with the device can instruct the processor to monitor that DHCP leases file and extract the host name for each device on the network. The computer instructions for extracting the host name associated with the device can also instruct the processor to associate the host name for each device with the IP and MAC addresses for each device. For example, the computer instructions can instruct the processor to examine the leases file for entries matching the MAC address of a device for the most recent non-blank host name entry.
The router configured to monitor the network traffic on a home network can include computer instructions to extract other pertinent identifying information.
The computer instructions to extract other pertinent identifying information can instruct the processor to capture outgoing Hypertext Transfer Protocol (HTTP) requests from the devices on the network. The type of device, the operating system used by the device, and the browser type of the device can be captured and stored. This information can be captured by examining the user agent of outgoing HTTP requests. For example, one or more devices can be selected for the processor to receive the HTTP request for, the devices can be selected using the user interface, and these computer instructions can instruct the processor to examine an Ethernet or 802.11 header of the outgoing request packets to obtain the MAC address of the device and extract the HTTP requests. The User Agent header of the HTTP request has the information from which the device type, OS, & browser type can be deduced or extracted.
The router configured to monitor the network traffic on a home network can include computer instructions to monitor the incoming data rates to the device.
The computer instructions to monitor the incoming data rates to the device can instruct the processor to determine the data rate being transferred to each device on the network. The computer instructions can be configured to set up a three tier hash table for scalably sorting traffic by device. When a new device is added to the system a new queue, with no QoS rate values and default priority, is established, and an associated leaf entry added to the hash table. Packets are sorted by the hash table and pass through the queue which serves as a simple byte counting mechanism before QoS is applied.
The router configured to monitor the network traffic on a home network can include computer instructions for monitoring the outgoing data rates for the device. The computer instructions for monitoring the outgoing data rates for the device can instruct the processor to determine the data rate being transferred from each device on the network. These computer instructions can function substantially similar to the computer instruction to monitor the incoming data rates to the device can instruct the processor to determine the data rate being transferred to each device on the network.
The router configured to monitor the network traffic on a home network can include computer instructions for controlling incoming data rates to, and outgoing data rates from, the device.
The computer instructions for controlling incoming data rates to and outgoing data rates from the device can instruct the processor to acquire the data rates from the computer instructions for monitoring the outgoing data rates for the device and the computer instructions for monitoring incoming data for the each device, and apply a QoS to control the data rates. Queues are maintained for the traffic of each device. The servicing of those queues is managed by one of several algorithms capable of supporting the desired QoS strategy. In this case the QoS strategies are bandwidth caps and minimums; and relative priority of traffic. Queue management algorithms include Hierarchical Token Bucket and Stochastic Fairness Queuing.
The router configured to monitor the network traffic on a home network can include computer instructions for speaking with a personal device having a software package thereon, wherein the software package enables the mobile device to control and monitor, monitoring the outgoing data rates for each device and the incoming data for each device. These computer instructions can instruct the processor to communicate with a personal data device and transmit the monitored incoming data rates and outgoing data rates for each device to the personal device, and to receive input from the personal device to control the allowable data rates for each device.
The router configured to monitor the network traffic on a home network can include computer instructions for capturing the outgoing HTTP requests made by the device.
The computer instructions for capturing the outgoing HTTP requests made by the device can instruct the processor to capture outgoing web addresses from each device on the network by examining the request and host HTTP requests. For example, the HTTP request contains the destination address and host. Together they form the URL (Uniform Resource Locator) or “web address.” And the computer instructions for capturing the outgoing HTTP requests made by the device can instruct the processor to capture outgoing web addresses from each device on the network by examining the request to identify the host for the request, then the processor can track the host portion to identify the destination portion, i.e. device, and the computer instructions can instruct the processor to associate the host with the device in a report or table.
The router configured to monitor the network traffic on a home network can include computer instructions to capture signal events.
The computer instructions to capture signal events can instruct the processor to capture signal events such as when a device on the network is activated. For example, when a child comes home from school and begins surfing from a computer or playing an online game on a console, these computer instructions can instruct the processor to identify when a specific device is activated and can send an alert to the cell phone of the child's parent. The processor can detect when the selected device is activated by detecting when the device begins making non-automated outgoing requests. Non-automated requests are characterized by significant traffic in user clients like browsers. The type of client is determined by examining User Agent of the HTTP requests. Significant traffic is determined by data rate.
The router configured to monitor the network traffic on a home network can include computer instructions for identifying the device hardware an operating system, as well as a browser type.
The computer instructions for identifying the device hardware, an operating system, and a browser type can instruct the processor to examine the user agent of the outgoing HTTP requests. For example, these computer instructions can instruct the processor to inspect the User Agent, which is a header field in the HTTP request, parse the field to obtain the browser, operating system, and device type parsing the field, and associate the extracted information with the device in a database or report that is available to a user upon request.
The router configured to monitor the network traffic on a home network can include computer instructions for Network Address Translation (NAT) traversal.
The computer instruction for NAT traversal can instruct the processor to contact a relay server in the public internet which attempts to call back to the router. If a NAT is intervening, the computer instructions for NAT traversal can instruct the processor to determine the type of NAT and apply the appropriate NAT traversal algorithm. The computer instructions for NAT traversal can instruct the processor to use a Universal Plug and Play (UPnP) to request port forwarding to the external address of the router. In another embodiment, the computer instructions for NAT traversal can instruct the processor to request a firewall pinhole. The computer instructions for NAT traversal can use additional NAT traversal protocols including Session Traversal Utilities for NAT (STUN), which maintains a usable external address through multiple layers of NAT of certain types, and Traversal Using Relays around NAT (TURN), which actually relays data where an external address isn't sufficient.
The personal device configured to communicate with the router can be a mobile phone, a laptop, a mobile processor, such as a tablet, a personal computer, similar devices, or combinations thereof.
The personal device configured to communicate with the router can include computer instructions to communicate with the router through the local area network or another network by traversing the NAT on which the Local Area Network (LAN) may be connected, as well as to the general Internet, including cell networks.

The computer instructions to display identifying information for a device in communication with the router can instruct the personal device processor to receive and display information captured for each device on the network. The information can be displayed graphically in line or bar charts.
The personal device configured to communicate with the router can include computer instructions to display QoS settings for the device in communication with the router.
The computer instructions to display QoS settings for the device in communication with the router can instruct the personal device processor to communicate with the router to determine the QoS for each device on the network and display the information on the personal device.
The personal device configured to communicate with the router can include computer instructions to adjust QoS settings for a device in communication with the router.
The computer instructions to adjust QoS settings for a device in communication with the router can instruct the processor to receive input from a user such as a double click, a squeeze on a touch screen, a tap on a touch screen, a click and drag, or other input to adjust the allowable data rate for each device on the network.
For example, the personal device configured to communicate with the router can include computer instructions to allow manipulation of the graphical display to control the data rates for the device and change the QoS setting of the device in communication with the router.
The computer instructions to allow manipulation of the graphical display to control the data rates for the device and change the QoS setting of the device in communication with the router can provide pairs of vertical sliders for each device. The vertical sliders can be calibrated and adjacent to the line or bar graph for all devices. The vertical sliders can be calibrated to the vertical range of the line or bar graph and used to set minimums and maximums for the data traffic of the devices associated therewith. The result of manipulating the vertical sliders can be observed in real time in the line or bar graph, not only for the device being manipulated but for the other devices that share the bandwidth on the router. In one or more embodiments, the computer instructions can provide single sliders for each device next to the shared line or bar graph for all devices that set relative priorities of the traffic for each device.
As above the result of manipulating the sliders can be observed in real time in the graphs. These computer instructions can do one of the foregoing or can do both.
The personal device configured to communicate with the router can include computer instructions to program and receive an event on the router, such as when a LAN device comes into use.
The computer instructions to program and receive an event on the router, such as when a LAN device comes into use, can instruct the personal device processor to communicate with the router and to relay inputs on one or more alerts desired by a user, and then instruct the router to send an alert, such as a visual or audio alert, when one or more of relayed desired inputs occur.
The personal device configured to communicate with the router can include computer instructions to graphically display real-time and historical data rates of the device in communication with the router.
The computer instructions to graphically display real-time and historical data rates of the device in communication with the router can instruct the personal device processor to receive real-time and historical data rates from the router, and to display the real-time and historical data rates on the personal device.
The personal device configured to communicate with the router can include computer instructions to display a list of web addresses requested from the device in communication with the router.
