Quality of Service Routing in Next Generation Networks

National audienceThe deployment of IP-based Television (IPTV) combined with conversational services such as telephony over IP and presence services, over different core and access networks, raises the issue of multi-constrained QoS routing in heterogeneous networks. Our poster summarizes our proposition to solve the Inter-domain QoS routing by (i) solving efficiently the multi-constrained QoS routing in each routing domain, (ii) implementing sufficient cooperation between path computation entities of the concerned domains
