Abstract

A system and method of collecting and maintaining historical top communicator information on a communication device. The system and method is located on a communication device, which is attached to a network, and responds to internal an external data requests for host information. A top communication storage device and an RMON protocol storage device are inspected by top communicator logic for communicator information. Non-user excluded information is stored within the top communication storage device and updated periodically, along with an RMON database, according to a RMON alarm/user history poller and a user defined timer.

Claims

1. A system for collecting and maintaining historical top communicator information on a communication device for retrieval by a source, comprising;

an SNMP stack for receiving a retrieval request from said source;

a first storage area for storing specific host information concerning each host;

a second storage area for storing specific user-defined top communicator information which has not been excluded from said first storage area, said top communicator information identifies a plurality of hosts involved in most network traffic by indicating an amount of network traffic that passes through each host, an originator of said network traffic, and an intended receiver of said network traffic;

a third storage area for storing historical information retrieved from said second storage area according to a sampling period;

wherein said SNMP stack specifies the implementation of SNMP protocol within said communication device to retrieve said top communication information from said communication device and to store said top communication information historically from said second storage area to said third storage area.

2. The system of claim 1, wherein said specifying the implementation of SNMP protocol within said communication device is performed by a top communicator logic.

3. The system of claim 2, wherein said timer is defined by a user.

4. The system of claim 1, wherein said source is selected from the group consisting of an internal source and an external source.

5. The system of claim 4, further comprising a user history poller, wherein said poller initiates the updating of said third database based upon a timer.

6. The system of claim 1, wherein said first storage area is a database.

7. The system of claim 1, wherein said second storage area is a database.

8. The system of claim 1, wherein said third storage area is a database.

10. The method of claim 1, wherein said source is selected from a group consisting of an internal source and an external source.

11. The method of claim 2, wherein said external source is a network management system.

12. The method of claim 1, wherein said step of updating said third storage area is performed based upon a user specified period.

13. The method of claim 1, wherein said first database is an nlHost table.

14. The method of claim 1, wherein said third storage area is an RMON user history table.

15. The method of claim 1, wherein said first storage area is a database.

16. The method of claim 1, wherein said second storage area is a database.

17. The method of claim 1, wherein said third storage area is a database.

9. A method of collecting and maintaining historical top communicator information on a communication device for retrieval by a source, comprising the steps of:

receiving host information and storing specific information concerning each host in a memory within a first storage area;

excluding user defined top communicator information from said specific information stored in said first storage area to produce a sampled version, said top communicator information identifies a plurality of hosts involved in the most network traffic by indicating an amount of network traffic that passes through each host, an originator of said network traffic, and an intended receiver of said network traffic;

storing said sampled version within a second storage area;

calculating said top communicator information by utilizing said sampled version;

utilizing a third storage area to store historical samples of said sampled version from said second storage area for collection by said source according to a sampling period; and

utilizing said sampling period of said third storage area to control the collection and calculation of data in said second storage area.
