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

Alternative mechanism that preserve the IP multicast model but employ join/leave messages to track local group membership for broadcast LANs (shared medium LANs) was proposed in this paper.
