ABSTRACT:
An efficient distributed technique for setting up, taking down, and updating connections in a communications network, which is robust in the presence of failures. More specifically with this invention a path for a connection is computed and reservation requests are simultaneously sent through separate channels to each of a set of nodes of the path for the connection to reserve and determine if resources are available for the connection. Upon acknowledgement that the links for the connection are available and have been reserved, a setup message is sequentially transmitted between the adjacent nodes along the path until the setup messages reaches the destination node. The switches in each node then configure themselves in response to the setup message so as to establish the connection.
