Hierarchical level-based internet protocol multicasting

摘要: Hierarchical Level-Based IP Multicasting (HLIM) is a method for the multicasting of data packets from source to number receivers on network that supports both host and mobility. In HLIM, routers are assigned hierarchical levels become designated routers. The also used define scope region in which multicast be delivered. Each associated with unique root identifier (RID). Scope information identifiers placed into address so packers will distributed hosts within region. If (receiver or source) sub-network moves out but desires continue receiving multi-cast can request receipt such its new parent router through use RID binding point (BPT). this manner, HLIM provides shared shortest-path tree without using center like core rendezvous point. not only mobility (movements hosts) with/without hosts). oriented operate networks, applied flat networks by emulating organized mechanisms as Private Network-to-Network Interface (“PNNI”) protocol ATM multimedia support mobile wireless (“MMWM”). Thus, implemented long nodes connected hierarchy, physically virtually.
