Abstract
A system, method and article of manufacturing for increasing link bandwidth occupation in a high speed packet switching digital network by enabling merging the traffics provided by different source users over several network node entry ports and to be propagated throughout network paths toward a same destination network port. To that end, at network ingress, the original packets provided by said source users and entering the network, are encapsulated with a so-called Single Sided Virtual Channel (SSVC) header including a Data Link Connection Identification (DLCI) field. Then, the packets provided by said source users and entering a given network node along their predefined path are monitored. Said packets SSVC headers DLCI fields are loaded with a same Virtual Channel number, whereby the corresponding traffics are being merged into a same channel, down to the destination network node. Then, the packets in said destination node are de-encapsulated from said SSVC header.
