Abstract

Non-guaranteed QoS and low benefit are essential problems when VoD runs in IP network. Based on network priority, mass SLA priority, as well as economic priority of multicast service of VoD in EPON, a QoS priority utility algorithm (utility priority) is introduced for multicast. When congestion is occurring, the network resources are re-allocated among multicast group according to their utility priority. This measure can not only reduce bandwidth requirement and packet loss, but also can increase bandwidths benefit by converging them on the higher value services. By turning disorderly and variable-length Ethernet frame into orderly and constant-length one, the delay jitter of VoD packet is reduced. The result of simulation well verifies its merits.
