<p>Recovery time upon the failure of a link (L12, L23, L34, ...) or switching system (102, 104, 106, 108, ...) in an asynchronous data network can be minimized if downstream data switches (102, 104, 106, 108, ...) can provide upstream messages (R21, R32, R43, ...) to upstream switching systems (102) indicating to upstream switching systems (102) that the downstream traffic arrived intact and was properly handled. In one embodiment, the loss or failure of the upstream status message to an upstream switching system (102), causes an upstream switching system to reroute data traffic around a failed switch (106) with a minimal amount of lost data.</p> |
