Abstract
A system distributes extended traffic accounting information of bandwidth availability on links throughout a network. For example, routers within the network utilize an extended reservation protocol to calculate bandwidth availability information for links. In calculating the bandwidth availability information, the extended reservation protocol accounts for not only the amount of bandwidth reserved on each of links via the resource reservation protocol itself, but also for the bandwidth usage by other traffic on the links, such as Label Distribution Protocol (LDP) traffic or Internet Protocol (IP) traffic. The routers exchange bandwidth availability information using a routing protocol to gain network-wide knowledge of bandwidth availability.
