Network-Coding Multicast Networks With QoS Guarantees

It is well-known that without admission control, network congestion is bound to occur. However, to implement admission control is difficult in IP-based networks, which are constructed out of the end-to-end principle, and semantics of most major signaling protocols can only be interpreted at the edge of the network. Even if routers can perform admission control internally, the path computation and the state updating activities required for setting up and tearing down each flow will overwhelm the network. A new QoS architecture, called a non-blocking network, has been proposed recently, and it requires no internal admission control and can still offer hard QoS guarantees.
