Using A Link Attribute To Inform Nodes Of The Availability Of Traffic Management Resources

摘要

In one embodiment, informing nodes of traffic management resource availability includes establishing whether there is an available traffic management resource at a first node, where a traffic management resource tracks usage of bandwidth by a tunnel at the first node. Whether there is an available traffic management resource is recorded in a traffic management link attribute. The traffic management link attribute is sent to second nodes to inform the second nodes of whether there is an available traffic management resource at the first node.
