System and method for retrieving network management data from multiple network elements
View Patent ↗A system for, and method of, retrieving network management data in a network and a network management station incorporating the system or the method. In one embodiment, the system includes: (1) an information querier, associated with a network management station, that develops a query for at least some network management data from a target agent in the network and assigns a path for a response from the target agent that is unique to the target agent and (2) a response receiver, associated with the information querier, that receives, via the path, the response from the target agent containing the at least some the network management data.
1. A system for retrieving network management data in a network, comprising:
an information querier, associated with a network management station, that transmits a plurality of queries for at least some network management data from a plurality of distinct target agents in said network, each query being addressed to a corresponding one of said different target agents and being transmitted in succession independent of receiving a response from any of said target agents, each query directing a response from said each of said plurality of said target agents to a different port of said information querier that uniquely corresponds to a particular agent; and
a response receiver, associated with said information querier, that receives, via at least one of said different ports, a response from at least one of said target agents.
2. The system as recited in claim 1 wherein said information querier identifies said path in a source address of a packet bearing said query.
3. The system as recited in claim 1 wherein said information querier identifies said path in a port assignment of a packet bearing said query.
4. The system as recited in claim 1 wherein said response receiver comprises a buffer that receives and contains said responses, said response receiver reading said responses from said buffer following a predetermined period of time.
5. The system as recited in claim 1 wherein said query and said response conform to a Simple Network Management Protocol.
6. The system as recited in claim 1 wherein said network is an Internet Protocol network.
7. A method of retrieving network management data in a network, comprising:
transmitting a plurality of queries for at least some network management data from a plurality of different target agents in said network, each query being addressed to a corresponding one of said different target agents and being transmitted in succession independent of receiving a response from any of said target agents, each query directing a response from said each of said plurality of said target agents to a different port of said information querier that uniquely corresponds to a particular agent; and
receiving, via at least one of said different ports, a response from at least one of said target agents.
8. The method as recited in claim 7 further comprising identifying said path in a source address of a packet bearing said query.
9. The method as recited in claim 7 further comprising identifying said path in a port assignment of a packet bearing said query.
10. The method as recited in claim 7 wherein said receiving comprises receiving said response from said target agent containing said at least some said network management data into a buffer and said method further comprises reading said response from said buffer following a predetermined period of time.
11. The method as recited in claim 7 wherein said query and said response conform to a Simple Network Management Protocol.
12. The method as recited in claim 7 wherein said network is an Internet Protocol network.
13. A network management station, comprising:
a network interface for linking said network management station to elements in an Ethernet network to be controlled;
a network control circuitry, coupled to said network interface, for controlling said elements based at least in part on network management data retrieved from said elements; and
a system for retrieving said network management data from said elements, including:
an information querier that develops a plurality of Simple Network Management Protocol queries for at least some network management data from a plurality of different target agents associated with said elements, each query being addressed to a corresponding one of said different target agents and being transmitted in succession independent of receiving a response from any of said target agents, each query directing a response from said each of said plurality of said target agents to a different port of said information querier that uniquely corresponds to a particular agent, and
a response receiver, associated with said information querier, that receives, via at least one of said different ports, a response from at least one of said target agents.
14. The network management station as recited in claim 13 wherein said information querier identifies said path in a source address of an Internet Protocol packet bearing said query.
15. The network management station as recited in claim 13 wherein said information querier identifies said path in a port assignment in an Internet Protocol packet bearing said query.
16. The network management station as recited in claim 13 wherein said response receiver comprises a buffer that receives and contains said response, said response receiver reading said response from said buffer following a predetermined period of time.
17. The system as recited in claim 13 wherein said query and said response conform to a Simple Network Management Protocol.
