Abstract
A method and differential services network are provided for propagating status information. Status information may be obtained at the first edge node (or egress router). A first status message may be forwarded from the first edge node (or router) to the first core node (or router). The first status message may be updated based on status information at the first core node (or router). The updated first status message may be propagated to the second edge node (or ingress router).
Claims27
A method of propagating status information through a network having a first edge router, a second edge router, a first core router, the method comprising:
- propagating first status information from said first edge router to said first core router;
- and
- propagating second status information to said second edge router, wherein said second status information is based on said first status information.
A method of propagating status information in a network, said network comprising a first edge node, a second edge node, a first core node and a second core node, said method comprising:
- obtaining status information at said first edge node;
- propagating a first status message from said first edge node to said first core node;
- updating said first status message based on status information at said first core node;
- and
- propagating said updated first status message to said second edge node.
A differential service network comprising:
- a first edge node;
- a second edge node;
- a first core node and a second core node both provided between said first edge node and said second edge node;
- and
- a controlling device that controls said network and makes decisions regarding data flow in said network, said network operating such that status information is propagated from said first edge node to said second edge node along a propagation path.
