| In this work, we are interested in the routing problem in Service Overlay Network, a network implemented upon Internet to offer different services such as QoS, Resiliency, Peer to peer, ...etc. We have developed a probabilistic preventive routing of deterioration of service (BProb) based on measuring the available bandwidth. This one looks for the path which minimizes the probability that the available bandwidth is lower than the bandwidth required by the connection. Our routing is sustained by the supervision of the states of the links through a continuous measure of the available bandwidth. An analysis of the performance of Bprob was made compared to that of the routing which chooses the path which maximizes the available bandwidth (Bmax). We noticed that the routing Bprob offers a better performance with regard to the metrics of QoS.;Keywords: service overlay network (SON), active measurement, available bandwidth, QoS routing, probabilistic routing... |
