ON/OFF Sources in an Interconnection Network: Performance Analysis when Packets are Routed to the Shortest Queue of two Randomly Selected Nodes

摘要

The authors investigate a system with N servers and with N sources connected with the servers. A sources can be in state «on» or «off». In state «on» the source generates the Poisson flow of packets of rate $lb$. The service time of a packet is distributed exponentially with mean one. Upon its arrival a packet is directed to the server with the shortest queues of the following two servers: the server where the packet has been generated and another randomly selected server. The queue length probability as N o infty$ is investigated.
