Abstract

Methods of managing a network comprising a plurality of agents. The methods may comprise the step of storing a plurality of agent data files corresponding to the plurality of agents. The methods may also comprise the step of receiving periodic status messages from at least a portion of the plurality of agents. Upon receiving a status message from a first agent, the methods may comprise the step of updating an agent data file corresponding to the first agent. Also, the methods may comprise the steps of periodically identifying agent data files from the plurality of agent data files that have not been updated for a predetermined amount of time; and sending a request for response to a second agent corresponding to an agent data file that has not been updated for a predetermined amount of time.

Claims

1. A method of managing a network with a host computer comprising at least one processor and operatively associated memory, the network comprising a plurality of agents, wherein the method comprises:

storing at the memory a plurality of agent data files, wherein each of the agent data files corresponds to one of the plurality of agents executed by at least one computer;

at least a portion of the plurality of agents sending periodic status messages to the host computer according to a predetermined schedule, wherein each of the periodic status messages comprises status information describing the operation of the agent from which the periodic status message originated;

receiving by the host computer the periodic status messages;

upon receiving a status message from a first agent, the host computer updating an agent data file corresponding to the first agent;

the host computer periodically identifying agent data files from the plurality of agent data files that have not been updated for a predetermined amount of time;

the host computer sending a request for response to a second agent corresponding to an agent data file that has not been updated for a predetermined amount of time; and

the host computer, for each of the plurality of agents, analyzing historical status information describing the operation of the agent and received from periodic status messages to determine a failure threshold; and

the host computer, for each periodic status message received from an agent selected from the plurality of agents, comparing status information describing the operation of the agent to the failure threshold associated with the agent.

2. The method of claim 1, further comprising updating an agent data file corresponding to a third agent upon receiving a status message from the third agent.

3. The method of claim 1, wherein sending the request for response to the second agent comprises at least one of the group consisting of pinging the second agent and initiating a Trivial File Transfer Protocol (TFTP) session with the second agent.

4. The method of claim 1, further comprising adding the second agent to a list of agents in default if no response to the request for response is received.

5. The method of claim 1, further comprising adding the second agent to a list of agents in default if its corresponding agent data file is not updated within the predetermined amount of time more than a predetermined number of times.

6. The method of claim 1, further comprising communicating with at least one of the plurality of agents via a wireless connection.

7. The method of claim 1, wherein the status message comprises an indication of at least one of the group consisting of Received Signal Strength Indication (RSSI), pilot signal to interference ratio (E_c/I_o), channel and an Ethernet status.

8. The method of claim 1, wherein the failure threshold is agent-specific.

9. The method of claim 1, wherein the failure profile is based on status information received from other agents prior to the failure of the other agents.

17. The computer system of claim 1, wherein the host is further configured to compare the status information to at least one failure profile, wherein the failure profile is based on status information received from other agents prior to the failure of the other agents.

10. A computer system comprising:

a plurality of agents executed by computer devices; and

a host computer device in communication with the plurality of agents via a network, wherein the host computer device is configured to;

store a plurality of agent data files, wherein each of the agent data files corresponds to one of the plurality of agents, wherein at least a portion of the plurality of agents are configured to transmit periodic status messages to the host computer device according to a predetermined schedule, wherein each of the periodic status messages comprises status information describing the operation of the agent from which the periodic status message originated;

receive the periodic status messages from at least a portion of the plurality of agents;

upon receiving a status message from a first agent, update an agent data file corresponding to the first agent;

periodically identify agent data files from the plurality of agent data files that have not been updated for a predetermined amount of time;

send a request for response to a second agent corresponding to an agent data file that has not been updated for a predetermined amount of time;

for each of the plurality of agents, analyze historical status information describing the operation of the agent and received from periodic status messages to determine an failure threshold; and

for each periodic status message received from an agent selected from the plurality of agents, compare status information describing the operation of the agent to the failure threshold associated with the agent.

11. The computer system of claim 10, wherein the network comprises a proprietary network and a remote network.

12. The computer system of claim 10, wherein the host is further configured to send the request for response to the second agent by at least one of the group consisting of pinging the second agent and initiating a Trivial File Transfer Protocol (TFTP) session with the second agent.

13. The computer system of claim 10, wherein the host is further configured to add the second agent to a list of agents in default if no response to the request for response is received.

14. The computer system of claim 10, wherein the host is further configured to communicate with at least one of the plurality of agents via a wireless connection.

15. The computer system of claim 10, wherein the status message comprises an indication of at least one of the group consisting of Received Signal Strength Indication (RSSI), pilot signal to interference ratio (E_cI_o), channel and an Ethernet status.

16. The computer system of claim 10, wherein the failure threshold is agent-specific.

18. A computer readable medium having instructions stored thereon that when executed by a processor, cause the processor to:

store a plurality of agent data files, wherein each of the agent data files corresponds to one of the plurality of agents executed by at least one computer;

periodically receive from at least a portion of the plurality of agents periodic status messages according to a pre-determined schedule, wherein each of the periodic status messages comprises status information describing the operation of the agent from which the periodic status message originated;

receive the periodic status messages;

upon receiving a status message from a first agent, update an agent data file corresponding to the first agent;

periodically identify agent data files from the plurality of agent data files that have not been updated for a predetermined amount of time; and

send a request for response to a second agent corresponding to an agent data file that has not been updated for a predetermined amount of time;

for each of the plurality of agents, analyze historical status information describing the operation of the agent and received from periodic status messages to determine an failure threshold; and

for each periodic status message received from an agent selected from the plurality of agents, compare status information describing the operation of the agent to the failure threshold associated with the agent, wherein the computer readable medium is a tangible article.
