Control method of communication between a system of head of network, and a plurality of client systems.

摘要

Method of controlling communication between a head system network and a plurality of client systems.The present invention relates to a method for controlling communication between a head system network (1 - 6) and various systems of the customer (1, 3, 22) through a network (7), in which,For each receiver.Only one closest system among the systems multidifusu00f5es routers (35 to 38) in the network is configured to send a copy of a message addressed to the group of which the multidifusu00f5esThe receiver is a member directly to the receiver.Includes: the maintenance of the group information of subscribers that connects each system recorded among the various systems of customer with a group from among the plurality of groups associated with the subscriber.And the allocation of systems of client registered to at least one group of multidifusu00f5es,So that all the systems of client associated with a particular group of subscribers are in a group of multidifusu00f5es common.The information uniquely identifying the system multidifusu00f5es router closest to the receiver to a first client system is obtained; and the first client system is designated to aThe group of subscribers including at least one client system further has the same system multidifusu00f5es router closest to.
