The performance of one router will degrade and the network will have congestion because many packets arrive in the router at the same time. A new congestion prevention policy for router, which is based on the M/G/1 retrial queue with Bernoulli vacation and generic retrial, vacation, setup and service time, is proposed. In this policy, the packets from other routers find the router busy and the packets will be queued in the orbit in accordance with a first-in-first-out (FIFO) discipline which the router starts to process. Only the packet at the head of the queue is allowed access to the router for processing. The ergodical condition of this model is analyzed and theprobability generating functions of content of system are obtained. At last, some performance measures and numerical resultsare given.
