<p><P>PROBLEM TO BE SOLVED: To provide a method for managing virtual links in a multi-protocol label switched network. <P>SOLUTION: According to one aspect of the method, a virtual link which is made up of a set of links between two devices within the multiple protocol label switched network is regarded as a single entity by a control component of a label switching router. Each packet to be transported on the virtual link is labeled on the basis of its assigned forwarding equivalence class. A specific label is bound to a corresponding forwarding equivalence class. The specific label is used on packet belonging to the same forwarding equivalence class and such packets can then be forwarded onto any one of the links within the virtual link. <P>COPYRIGHT: (C)2003,JPO</p> |
