Abstract

The invention discloses a method for carrying out service transmitting in a synchronous digital hierarchy (SDH) network. First, it determines the number of the demanded virtual containers (VC) according to the current service to be transmitted. Secondly, the VCs are mapped a virtual concatenation VC frame by adopting virtual concatenation mapping method, and the VC frame is transmitted to the receiver unit by the same route. The receiver unit unmaps the received VC frame by the adjacent concatenation unmapping method. The method can avoid the question about bandwidth wasting in the SDH networks transmitting service, and the higher demand to each net ware in the SDH transmitting network, and the long time delay under the virtual concatenation. And the method also makes the SDH network has the strongpoint of the adjacent concatenation and the virtual concatenation in the transmitting service.
