Reliability Analysis and Congestion Control on Network Nodes
Shi Jian, Shaoping Wang · 2006
The reliability of computer network is related not only with the topology of the network and the reliabilities of the components, but also with the configurations of the nodes and the traffic flowing into the network. Nodes consist of two failure modes: congestive failure and failure related with inactivation of the software and hardware. The node's reliability related with the failure of hardware and software is obtained by modeling the node with general stochastic Petri net, and the node's reliability varied with the traffic is gotten by modeling the node as M/M/1/N and MX/M/1/N. In order to keep accordance with the specified reliability of the given node under condition of traffic and manage memory resource effectively, feedback control system theory is adopted to dynamically allocate memory resource changing with the traffic
