Abstract:
In most packet networks and the Internet, packets are queued at routers' output interfaces before being sent to next nodes. As the buffers for these queues are finite and the incoming traffic is unpredictable, with possible bursts, a fraction of arriving packets is lost, due to the buffer overflow. The packet loss ratio is thus one of the most important performance characteristics, widely studied via actual network measurements, simulations and mathematical modeling. The purpose of this paper is to discuss the methods of computing the loss ratio using queueing models and to collect the results obtained via the empty queue probability method. Various queuing models are taken into account, with general service time distribution and different assumptions on the arrival stream (Poisson, group structure, autocorrelated).
