Abstract
It is often required to send a plurality of streams of data in parallel between two network nodes in a synchronous transmission network and also to maintain a particular alignment between those streams of data. This is particularly required when the streams of data are to be transmitted over a wide area network, for example, for data mirroring applications. Virtual concatenation is used for each of the individual data streams as known in the art and in addition, the individual virtual concatenation processes are synchronized or co-ordinated. At a destination node it is then possible to realign the individual data streams with respect to one another.
