Abstract
The present invention relates to network nodes and methods that use an encoding scheme for encoding a point-to-multipoint traffic path from one ingress node to a plurality of egress nodes in, for example, a Multi-Protocol Label Switching network. According to the encoding scheme a so-called common ERO is used. The common ERO specifies a list consisting of nodes that are common to several sub paths in order to provide a compression mechanism that reduces the size of path messages that are used for signaling the point-to-multipoint traffic path.
