ABSTRACT:
A method of transmitting path overhead data between an ingress section and an egress section of a network element is described. A portion of the path overhead data is inserted into one or more predetermined bytes of the transport overhead of the data frame before transmission to the egress section. Consequently, the egress section does not require a pointer processor to retrieve the desired path overhead data. Elimination of the pointer processor results in reduced complexity and cost for the network element. The method can be applied to tandem connection monitoring (TCM) and other processes in which path overhead data are transferred.
