A Heuristic and Dynamic Multicast Router Algorithm Based on QoS

As the internet developing rapidly, new requirements, such as video on demand and video conference are emerging. QoS based Multicast router arouses widely attention. This paper proposes a Delay-constrained Dynamic Multicast Routing Heuristic Algorithm (DDMRH) with combining FLSPT algorithm and the greedy idea. The emulation test shows that DDMRH algorithm can meet the demand of multicast application that is limited end to end delay and has variable numbers. With the fast development of internet and multimedia technology, some new requirements, such as stream media, video conference, network game, distance education come forth.
