    Abstract: In order to measure the latency of a particular transport service from end to end, a method of measuring the latency of a transport connection between a first network node (NI ) and a second network node (N2) is provided, which makes use of a virtual concatenation function with a buffer (B) to compensate the differential delay between members in a received virtual concatenation group. In particular, the first network node (Nl ) creates a virtual concatenation group which has as members at least two multiplexing units (VC4_1, VC4_2). A first of the two (VC4_1 ) is used as a reference for the latency measurement. The second (VC4_2) is sent to the second network node (N2), where it is looped back to said first network node (Nl ). The first network node (Nl ), by using its buffer (B) available for re-aligning members of a virtual concatenation group, determines a latency difference between the first and second multiplexing units (VC4_1, VC4_2).

    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.

    Abstract: The invention relates to a method and to a device for converting virtually concatenated data streams into contiguously concatenated data streams. The data are transmitted in containers and N containers are combined in one multiframe. The virtually concatenated data streams consist of X partial streams/channels. Every container that is allocated to the same location in the multiframe is identified by evaluating a multiframe indicator of the container. The time-shift of said identified containers of the partial data streams with respect to one another is measured. If such a time-shift is detected, only the leading containers are delayed in such a manner that a time-wise alignment of all containers is achieved. Every channel (KA1, KA2,...) is correlated with a pointer interpreter (PI1, PI2), followed by an flexible memory (ES1, ES2) and a pointer generator (PG1, PG2). The pointer generators are inter-synchronized and every pointer generator is equipped to control the read-out of the flexible memory that pertains to its channel. A channel that is selected as the master channel (KA1) is provided with an overhead inserter (OI1).
