The continuing and rapid growth of the Internet has created an extremely large capacity problem to the service and content provider's networks. The increased network traffic and the absence of service priority, usually produce high network congestions, delayed data and service transmissions and lack of throughput. The effect of these factors in A\V content transmission is to distort the initial content and decrease the content quality. To avoid this negative effect, service and content providers are looking for architectures that give them greater control on traffic passing through their domains and other heterogeneous networks. This paper proposes an experimental core network architecture (MPLS-DiffServ) presenting a solution for content providers that want reliable and agreed level of quality, even if the network is under congestion.
