Abstract

Efficient network management techniques for use in wireless environments are disclosed. In one embodiment of the present invention, a network system includes a server-client architecture, where a number of mobile clients (e.g., cell phones, PDAs, smart phones) wirelessly access and interact with the system via jack service points. The server uses an SNMP proxy. The server periodically collects data from the jack service points (or other network device), converts it into SNMP-compliant MIB representations, and caches the most recently collected data on the SNMP proxy. A network monitoring station (NMS) communicates with the SNMP proxy rather than directly with jack service points in the field. As such, no SNMP agent is necessary on the individual jack service points (or other network device).

Claims

1. A method for managing an SNMP wireless network, comprising:

receiving management data transmitted from a remote access point over a wireless network;

converting the management data into one or more SNMP management information bases (MIBs);

caching the MIBs within address space of an SNMP proxy;

receiving an SNMP community string from an SNMP network monitoring stations (NMS), the string indicating an ID of a target remote access point;

identifying target MIB data cached within the address space of the SNMP proxy, based on the target access point ID; and

sending the identified MIB data to the NMS.

2. The method of claim 1 further comprising the preliminary steps of:

measuring and recording the management data at the remote access point; and

periodically sending the recorded data to the SNMP proxy.

3. The method of claim 1 wherein the SNMP proxy resides on a server that receives the management data transmitted from the remote access point, the method further comprising:

sending the management data from the server to the SNMP proxy.

4. The method of claim 1 wherein the SNMP proxy resides on a server that receives the management data transmitted from the remote access point, the method further comprising:

determining if the server is managing the target access point; and

in response to the server not managing the target access point, sending an empty data set to the NMS.

5. The method of claim 4 wherein identifying target MIB data cached within the SNMP address space of the SNMP proxy is carried out in response to determining the server is managing the target access point.

6. The method of claim 1 wherein at least one of receiving the SNMP community string, identifying target MIB data, and sending the identified data to the NMS is carried out when the remote access point is not connected to the network.

7. The method of claim 1 wherein the SNMP proxy allows the NMS to retrieve data from any or all remote access points that were connected to the network at some point in time.

8. A method for managing an SNMP wireless network, comprising:

converting management data transmitted from a plurality of remote network devices over a wireless network into one or more SNMP management information bases (MIBs);

storing the MIBs; and

identifying stored MIB data corresponding to an ID of one of the remote network devices, the ID specified in an SNMP community string from an SNMP network monitoring station (NMS).

9. The method of claim 8 further comprising:

sending the identified MIB data to the NMS.

10. The method of claim 8 further comprising the preliminary step of:

receiving the management data transmitted from the plurality of remote network devices at a server that includes an SNMP proxy for carrying out the converting, storing, and identifying.

11. The method of claim 8 further comprising:

sending an empty data set to the NMS if target MIB data is not available.

12. The method of claim 8 wherein identifying the stored MIB data is carried out when the corresponding remote network device is not connected to the network.

13. The method of claim 8 wherein the method allows the NMS to retrieve data from any or all remote network devices that were connected to the network at some point in time.

14. The method of claim 8 further comprising the preliminary steps of:

measuring and recording the management data at the plurality of remote network devices; and

periodically sending the recorded data to an SNMP proxy that carries out the converting, storing, and identifying.

15. A machine-readable medium encoded with instructions, that when executed by a processor, cause the processor to carry out a process for managing an SNMP wireless network, the process comprising:

converting management data transmitted from a plurality of remote network devices over a wireless network into one or more SNMP management information bases (MIBs);

storing the MIBs; and

identifying stored MIB data corresponding to an ID of one of the remote network devices, the ID specified in an SNMP community string from an SNMP network monitoring station (NMS).

16. The machine-readable medium of claim 15 wherein the process further comprises:

sending the identified MIB data to the NMS.

17. The machine-readable medium of claim 15 wherein the process further comprises the preliminary step of:

receiving the management data transmitted from the plurality of remote network devices at a server that includes an SNMP proxy for carrying out the converting, storing, and identifying.

18. The machine-readable medium of claim 15 wherein the process further comprises:

sending an empty data set to the NMS if target MIB data is not available.

19. The machine-readable medium of claim 15 wherein identifying the stored MIB data is carried out when the corresponding remote network device is not connected to the network.

20. The machine-readable medium of claim 15 wherein the process allows the NMS to retrieve data from any or all remote network devices that were connected to the network at some point in time.
