On the Jitter Performance of FIFO and Priority Queues Mixture
none2We investigate the impact of the insertion of routers implementing
a non-preemptive priority queue mechanism (PQ) in a chain
of simple First-In-First-Out (FIFO) routers on the end-to-end
jitter experienced by high and low priority packets. The study
has been realized from an analytical point of view: we are able
to give the explicit form of the total jitter in relation to the time
that a packet spends in queue. We study its behavior as a function
of the input rate of the high and low priority packets and of
the number of PQ routers present in the whole path by showing
an evident decrease of the high priority packets jitter with
respect of the case of a chain composed by only FIFO nodes.noneC. TADDIA; G. MAZZINITaddia, Chiara; Mazzini, Gianluc
