Proxy agents in a network
View Patent ↗Methods for network device management are described. Load balancing for one or more proxy agents 114 , in a network 100 , is implemented based on a threshold load and a threshold interval. The load on each of the proxy agents 114 is compared with the threshold load to determine whether a given proxy agent is overloaded, under-loaded, or balanced.
1. A method comprising:
calculating, via a processor, a threshold interval based at least on a number of management requests pending with a plurality of proxy agents deployed in a network, wherein the threshold interval decreases as the number of management requests pending with the plurality of proxy agents increases and the threshold interval is based in part on an estimate of a number of management requests to be received with the plurality of proxy agents within a period of time;
calculating, via a processor, a threshold load based at least on the number of management requests pending with the plurality of proxy agents;
comparing, within the threshold interval, the threshold load with a load associated with each of the plurality of proxy agents;
determining whether each of the plurality of proxy agents is one of overloaded, under-loaded, and balanced based in part on the threshold load and the threshold interval; and
balancing the load associated with each of the plurality of proxy agents based on the determining by transferring a portion of the management requests pending with overloaded proxy agents to one of under-loaded proxy agents and balanced proxy agents.
2. The method as claimed in claim 1 , wherein the balancing the load comprises routing subsequent management requests to one of under-loaded proxy agents and balanced proxy agents.
3. The method as claimed in claim 1 further comprising storing information of the load associated with the plurality of proxy agents.
4. The method as claimed in claim 1 further comprising transmitting the threshold interval and the threshold load to the plurality of proxy agents.
5. The method of claim 1 , wherein the proxy agents manage a plurality of storage devices based on the management requests received from a central management station.
