HIGH-SPEED MULTICAST PATH SWITCHING

摘要

PROBLEM TO BE SOLVED: To provide an improved method for switching paths in a network routing device residing in a multicast distribution environment.

SOLUTION: The method includes maintaining a plurality of predetermined path sets in a data store correlated to a network routing device and causing each path set to correspond to a given network condition and to define a path for each data transmission session therein; receiving a message indicating a present network condition in the network routing device; selecting a path set from the plurality of predetermined path sets and causing the path set selected therein to be correlated to the current network condition; and configuring the network routing device in accordance with the selected path set.
