ABSTRACT:
In a communication network having a set of hosts and switch based label swapping communication nodes, each node has a control processor that is also a host that sends and receives messages via the switching apparatus in its associated node. Each node's control processor also includes a virtual connection (VC) traversal procedure that implements the methodology of the present invention. The control processor of any node along an established connection can initiate the transmission of a VC traversal message to the control processors of all the nodes along the connection. The VC traversal message is transmitted as one or more ATM cells, where each cell includes a standard ATM header for routing the cell to a neighboring node's control processor, as well as a VC traversal header in the body of the cell that identifies the connection being traversed. When a node receives a VC traversal message with a VC traversal header in it, the virtual connection traversal procedure in the receiving node processes that message by (A) performing whatever command is indicated in the VC traversal header, (B) routing a copy of the VC traversal message to the control processor of each node to which a data cell on the connection being traversed would be sent, and (C) performing a VC traversal header swapping operation on each such copy of the VC traversal message so that the VC traversal header in each forwarded VC traversal message identifies the segment of the connection being traversed by the control message.
