It is of necessity to transport time division multiplexing (TDM) traffic over packet network such as Ethernet. When TDM traffic is carried over Ethernet, it is necessary to improve end-to-end performance of Ethernet network. Based on frame structure defined in IETF RFC3985 and MEF 8, a kind of frame structure that comprises forward error correction (FEC) contents is presented, and a FEC method based...
Clock methods for TDM over Ethernet network are introduced. A new adaptive clock method is presented. The method is a kind of timestamp based adaptive method, but no timestamp needs transporting over Ethernet network. By using the local oscillator and a counter, the timestamp information (local timestamp) related to the service clocks of the two PEs (provide edge) can be attained. By statistic computing,...
