Abstract
Lossless delivery of an ATM cell based service over connection oriented multi-path networks is assured. The applicable network could be wired (to include optical fiber), or wireless, or a combination of these. A “queue” is added into the user information stream at the source node of the protection domain, and a working path receive queue is also introduced at the destination node. A low bandwidth sequence numbered (F like) OAM cell stream is carried cyclically from the source to the destination node over both the working and protection paths. A pre-determined delay of the sending of information over the network is employed. Upon an indication of an impairment of service, the delayed information is sent over a second path.
