Abstract
A protocol for a switching system that establishes multiple parallel paths between users through multiple autonomous switching planes by having a user desiring connection to issue connection requests to each of the switching planes. According to the invention, the user monitors the number of connections that have been successfully completed and if only some of the connections have been completed, because of conflicting requests, it follows a conflict protocol to issue retry requests to the planes on which the connection request was unsuccessful. Each switching plane follows the conflict protocol to respond to the retry request by disconnecting existing connections and completing at most one retried connection request.
