Abstract
Various embodiments relate to a method and apparatus for guaranteeing symmetrical delay in both directions for a Time-Division Multiplexing Pseudowire ('TDM-PW') service on a packet switching network ('PSN'), the method including the steps of using a transport method to specify a first path including a corresponding pair of unidirectional service tunnels for the TDM PW service between a master router and a slave router, detecting a failure on either of the corresponding pair of unidirectional service tunnels of the first path between the master router and the slave router, switching the master router and the slave router to a second path including a corresponding pair of unidirectional service tunnels, resetting a jitter buffer on the master router and the slave router and adjusting the jitter buffer to a halfway point, and transmitting and receiving data using the second path including the corresponding pair of unidirectional service tunnels.
