DATA TRANSMISSION PROCESS AND SYSTEM

摘要

A hierachy multicasting system (100) includes multiple clients coupled together in a tree structure (102) through a routing process (300). Data is transmitted from a data source (101) to a root node (112) of the tree structure (102). The root node (112) uses its up-link capacity to reflect the data to its children (122, 124). Through various filtering steps, the routing process (300) optimizes the tree structure (102) for efficiency and realibility. In addition, users (612, 622) behind different firewalls (610, 620) may communicate with each other. Therefore, they can be connected in the same hierachy multicasting tree structure (600).
