Abstract
In a method of processing a call in response to a connection request that includes reported bandwidths in both upstream and downstream directions, a communication node on the calling side (1) manages available bandwidths in upstream and downstream directions on a per-path basis; (2) searches for a path having upstream/downstream available bandwidths, which are greater than the upstream/downstream reported bandwidths; (3) if such a path can be found, accepts the call connection request as a call communicated in both directions on this path; (4) if such a path cannot be found, searches independently for a path having an available bandwidth greater than the upstream reported bandwidth and a path having an available bandwidth greater than the downstream reported bandwidth; and (5) if these two paths can be found, accepts the call connection request as a call communicated on the separate paths on a per-upstream- and downstream-direction basis.
