Patent Application
20050256886
The present disclosure relates generally to managing information about network elements, and more specifically to a system and method for storing element information.
A network may be characterized by several factors like who can use the network, the type of traffic the network carries, the medium carrying the traffic, the typical nature of the network's connections, and the transmission technology the network uses. For example, one network may be public and carry circuit switched voice traffic while another may be private and carry packet switched data traffic. Whatever the make-up, most networks facilitate the communication of information between at least two nodes, and as such act as communication networks.
At a physical level, a communication network may include a series of nodes interconnected by communication paths. These nodes and communication paths may represent elements of the network. Other elements may include applications, objects, other networks, software, firmware, and/or hardware, associated with the network. As such, a given network may include several elements, and proper management of the network may involve the daunting task of tracking and maintaining several pieces of information for each of these elements.
As the number of to-be-tracked elements and element characteristics increases and the frequency of tracking these characteristics increases, proper network management can become exceedingly difficult, overly resource intensive, and very expensive. Conventional management solutions tend to rely heavily on the availability of trained people and the scalability of deployed storage and computing resources. Unfortunately, these things may not always be available. Moreover, the cost and complexity of simply growing the network management system may become too high.
It will be appreciated that for simplicity and clarity of illustration, elements illustrated in the Figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements are exaggerated relative to other elements. Embodiments incorporating teachings of the present disclosure are shown and described with respect to the drawings presented herein, in which:
Network operators and enterprises often invest a great deal of time and money managing and maintaining their networks. Frequently, these network operators need to make decisions relating to network planning, resource availability, billing, troubleshooting, etc. Making proper decisions often requires a high level of network and user awareness. The individual or entity tasked with making these decisions may need to know or have access to volumes of information describing the past, current, and future status of the network. Moreover, this information may need to be readily-available and presentable to the decision makers in near real time.
As the size of the network and the number of network elements increases, the shear volume of information to be stored may become quite large. Moreover, a typical network operator may elect to track several metrics for each network element and to update these metrics frequently—causing the volume of stored information to continue to increase. The systems and techniques described below focus helping network operators better manage the use and maintenance of network related information. The described embodiments focus on large communication network implementations and the efficient use of available storage space.
In practice, a method incorporating teachings of the present disclosure may involve creating a structured text object that includes information representing a collection of metrics for a tracked network node. The network node may be, for example, a computing device, a communication link, and/or an interface mechanism. In some embodiments, the text object may be compressed into a binary element, and the binary element may be stored in a data store.
Making use of such a method may assist in relieving the over utilization of tablespace in some conventional databases that store vast amounts of detail metrics over long periods of time. In preferred embodiments, a system and/or method that incorporates teachings of the present disclosure may allow for a savings of up to 80% in tablespace—reducing physical disk space requirements, which may result in capital savings.
Moreover, a user may realize an increase in application performance due to reduction in disk I/O activities and an increase in the ease of data object management in the database as a result of having smaller table sets and fewer individual records.
While the following discussion focuses on large networks like the Public Switched Telephone Network (PSTN), wide area wireless networks, cable networks, managed Internet Protocol IP networks, etc., the teachings disclosed herein may also be used in other environments. For example, enterprise networks, local area networks (LANs), home LANs, the Public Internet, and/or other multiple element networks may also make use of the teachings disclosed herein.
As mentioned above in the brief description of the drawings,
NOC 12 may rely on manual command line interface interaction and/or software tools that use Simple Network Monitoring Protocol (SNMP) to manage and maintain information about a monitored network 14 and its monitored elements 16, which may include hardware, software, firmware, or combinations thereof. Depending upon implementation detail, SNMP may represent an effective way of determining if devices on a network like monitored elements 16 are operating properly. With SNMP, a monitored element may effectively monitor its own activity using built-in software programs sometimes referred to as agent software. Monitored elements 16 may store information about their own activity in a local data store or database called a management information base (MIB). The information stored in a local MIB may represent protocol data units (PDUs). An overall network management engine 18, like IBM's NetView, may be running as an application or engine on a NOC server 20 and may be capable of initiating a query to various agents on network 14 and effectively “ask” for a copy of their respective MIB information.
In practice, SNMP may be less of a “protocol” and more of a client server application that runs on the User Datagram Protocol UDP service of the TCP/IP protocol suite. Moreover, SNMP may not be the only option for network management “protocols”. For example, Common Management Information Protocol (CMIP) may be used to provide a powerful and secure alternative to SNMP. However, CMIP may require more overhead than SNMP.
Whatever the basis of the deployed network management system, the tools used may be very powerful and productive—potentially generating a great deal of element information that may need to be presented to a network operator or user via management console 22. In the embodiment depicted in
In operation, the maintained element information may be accessible through multiple modes of interaction, either individually or together. These modes and their implementation may include, among other things, GUIs, speech interaction, visual interaction, pen or stylus interaction, gestures-based interaction, quasi-virtual reality interaction or some other Haptics-based interaction. As such, NOC 12 may facilitate various modalities of human to computer interaction—simplifying the sharing of network information between multiple devices and multiple people.
In some embodiments, a system incorporating teachings of the present disclosure may be able to adapt information exchange to a given device, to a user preference, and/or network state or other condition. For example, an access device engine 24 may be capable of determining an access device type used by a calling or accessing party to interact with the network management engine 18. In some embodiments, access device engine 24 may include a format converter that can translate at least a portion of available network information into a signal and/or signal type receivable by a given access device type. As such, structured text objects representing maintained information may be created using an appropriate mark-up language. There may be several mark-up languages and techniques employed in system 10 to facilitate this and other capabilities. For example, a designer of system 10 and NOC 12 may elect to use XHTML, SMIL or some other mark-up language in conjunction with a speech recognition engine. Other designers may elect to use XML, VoiceXML, HTML, Voice Browser, Xforms, and/or other mark-up languages.
A managed network system incorporating teachings of the present disclosure may contain several elements. A network management engine 18 and agent software running on monitored elements 16 may be utilized to facilitate the on-going collection of element information. Network management engine 18 may reside at and be executing on a server, workstation or console, like NOC server 20. Network management engine 18 may automatically perform and/or allow a network administrator to perform network management functions and initiate management commands like get, get next, get bulk, inform, and set from a management console 22. As mentioned above, agents and/or other software entities associated with monitored elements 16, may initiate among other things response signals and/or event notifications or traps.
Additional system elements may include a compression engine 24, which may also execute at server 20 and a storage facility 26. Facility 26 may serve as a memory and may support a datastore configured to maintain a categorized set of information associated with elements 16. In some embodiments, a provider may want to ensure the availability of element information and may utilize a storage engine 28 to provide one or more storage related services. Engine 28 may facilitate a mirroring of information on facility 30. Engine 28 may also facilitate the implementation of some RAID level striping, Storage Area Network functionality, and/or some clustering capability.
In a centralized implementation like the one depicted in
As shown, NOC 12 may act as a centralized network-based repository of network element and/or network customer information. In other embodiments, the repository may be distributed and/or may be outside of the network. In a centralized implementation, an operator may elect to operate the system in a service bureau mode—supporting multiple networks and network types. For example, a wireless carrier having a wireless network 38, which may include elements like node 40, may elect to outsource element management services to an operator managing NOC 12. Moreover, elements of a larger network like public network 42, which may be, for example, the PSTN or the Public Internet, may also be tracked with components of NOC 12.
In some embodiments, various pieces of information including network information may be communication to an administrator or requestor in near real time and in a format that allows a graphical user interface to display textual information and/or visual representation of the monitored network information. As mentioned above,
Occasionally, the information or some subset of the information may exist in a legacy storage system. For example, a spreadsheet may exist that includes several fields populated with individual pieces of information. The spreadsheet may be located in one place and/or in several locations and may be filling a great deal of storage space. At step 48, one or more legacy storage devices may be accessed and a first and a second related metric may be collected therefrom at step 50.
At step 52, a single structured text object may be created from the first and the second metric and the single object may be linked and/or identified as containing multiple pieces of information about a given node, which may be for example a specific network element and/or a specific network user. At step 54, the text object may be compressed into a binary element and stored at step 56 in the datastore established at step 46.
In some implementations, an identification key may be associated with the binary element, and this process may occur at step 58. The key may help a system executing process 44 to quickly find a desired binary element. If, for example, a system is storing volumes of information in a datastore having an effective key system may greatly reduce the time necessary to respond to information requests and/or to modify maintained information. At step 60, a system executing process 44 may receive a request for information about a given tracked element. At step 62, the key system may be used to quickly determine which binary element stored in the datastore contains the requested information.
At step 64, the correct binary element may be retrieved and the element may be uncompressed at step 66. In some embodiments, the binary element will maintain multiple pieces of information; so, at step 68, the system may determine which piece of information maintained in the binary element is the requested metric. At step 70, the identified metric may be loaded into an accessible object and communicate to the requestor at step 72.
In addition to retrieving relevant information, a system executing process 44 may be used to add, modify, and update the maintained information. At step 74, a request to add or modify information may be received, and at step 76 the tracked node affected by the request may be identified. At step 78, an appropriate field of the tracked node's text object may be populated and/or modified. At step 80, another field of the text object may be populated with information keyed in by a user. Process 44 may then proceed to step 82, where a single structured text object may be created that includes the information input at steps 78 and 80, and the single text object may be linked and/or identified as containing multiple pieces of information about the tracked node. At step 84, the text object may be compressed into a binary element and stored at step 86 in the datastore established at step 46. The process of updating stored information may preferably be automated and this auto-update feature may be initiated at step 88.
In practice, process 44 may continue, may loop, and/or proceed to stop at step 90. Individual steps of process 44 may be amended, re-ordered, added, and/or deleted without departing from the teachings. In addition, the party or device performing various steps may be altered as well to make effective use of available resources within a system implementing some or all of process 44.
As mentioned above,
However received, information stored in memory 96 may be identifiable and searchable by one or more keys. As shown in
In operation, a user may have asked system 92 to return DSL link numbers for customers living in Austin. Memory 96 may have utilized the “A” in the customer identifier as the key and returned the found results to the user in GUI element 102. In some embodiments, additional information associated with the displayed information may be available. As such, the user of system 92 may click on DSL link 012 to gain access to whatever additional information is available.
Many of the above techniques may be provided by a computing device executing one or more software applications or engines. The software may be executing on a single computing platform or more than one. The platforms may be highly capable workstations, personal computers, microprocessors, servers, or other devices capable of performing the techniques. The device or devices may have a computer-readable medium having computer-readable instructions to direct a processor to create a structured text object that includes a first and a second tracked metric for a network node, to compress the structured text object into a compressed form, to receive a request for the first metric, to retrieve the compressed form of the structured text object, to uncompress the compressed form, and to initiate communication of a response to the request that comprises the metric.
