Real-time distributed multimedia applications have special requirements in terms of bandwidth, delay, delay jitter, etc. The current network, essentially being a connection-less network, provides only un-reliable, best-effort service. The data packets may follow different paths to the destination. The network resources, viz., switch buffer and link bandwidth, are fairly shared by packets from different...
Packet classification enables network routers to provide advanced network services including network security, quality of service (QoS) routing, and multimedia communications. In order to classify a packet, network nodes must perform a search over a set of filters using multiple fields of the packet as the search key. Viewing the classification problem geometrically, classifying an arriving packet...
Traditional IP multicast in a network domain is likely to imply a huge burden of storage and forwarding for routers and it's hard to support quality of service. The recent proposed application layer multicast is more scalable but increases traffic load and end-to-end delay. In the paper, we make multicast supporting comparable multi-class services on the overlay network comprising only edge routers...
