PIM-SM (Protocol Independent Multicast - Sparse Mode) is a multicast routing protocol that uses one central node (which we refer to with the Rendezvous Point ??RP??) for all transmitters in a multicast group. It builds source-specific trees to the transmitters whose data rates exceed a predefined threshold. Investigations have been done to improve and provide an efficient mechanism for switching between...
Network multimedia applications constitute a large part of Internet traffic and present a big challenge because of their sensitivity to delay, packet loss and higher bandwidth requirement. The need for guaranteed delivery and lower delay is caused by propagation of more the one domain. The domains used in this paper are co-operating and communicating with each other and all of them support IPv6 QoS...
Wireless distributed systems (WDS) are used to interconnect a set of access points to form a wireless extended service set (ESS). In this paper, we investigate the performance enhancements accomplished by using multiple interface cards per AP within the WDS system. Detailed simulations are conducted to bring out the enhancements accomplished by just using a few interfaces per access point in terms...
This paper presents a comparative study between JET (Just Enough Time) and a number of new preemptive channel scheduling algorithms in optical burst switching (OBS) with QoS (Quality of Service) requirement. In terms of performance criteria, loss rate in byte, access delay and end-to-end delay are considered. A 2-state MMPP (Markov Modulated Poisson Process) traffic generator on a 14-node mesh network...
