However, there is a possibilityfor a temporary disruption of multicast service due to the join latency and otherissues in handoff procedure. This paper proposes a scheme to solve such a problem.A smooth handoff mechanism is introduced to avoid unnecessary data loss. Besides,any mobility agent capable of multicast can be appointed to provide service to mobile hosts, which makes it possible to deploy the protocol widely. Discrete-eventsimulations were conducted to survey the performance of the proposed scheme. Thesimulation results show that the scheme has better performance than the comparedapproaches.展开更多

It has its unique advantages in one-to-many and many-to-many multimedia service applications. The network-wide multicast technology is based on a series of multicast-related protocols. This article introduces multicast protocols and technologies used in ZTE' s data products in terms of application environments. Moreover, it discusses ZTE's solution to multicast's controllability, manageability, security, operability and the added values the solution brought.展开更多

This paper introduces the principle of IP multicast technology, and presents an implementation of IP video multicasting in LAN based on Winsock2. Problems in IP multicast are also analyzed in brief.展开更多
