Abstract：
 The invention relates to a method for using single-broadcast address to mark multi-broadcast group in IP network, wherein said method comprises; first, selecting one node for each multi-broadcast group, as the main distributing node, and building multi-broadcast information list at said node, whose each item is relative to one multi-broadcast group; the content of item at least contains the name of multi-broadcast group; adding one virtual network interface at said node, and distributing one IP single-broadcast address to said interface; building the relation between virtual network interface and multi-broadcast group on said node, and using the single-broadcast address of virtual interface as the address of multi-broadcast group. The invention can confirm the unique property of multi-broadcast group address, and simplify the distribution of multi-broadcast group address and the design of multi-broadcast route protocol.
