In an MPLS network one or more monitoring probes are arranged to monitor data traffic on a particular path formed of several links in the network. The monitoring information from the probes is then sent to a Network Management module via links in a path through the network that avoids, so far as possible, any links in the path being monitored, as well as any links in paths that are considered to be important due to having high priority or that would be adversely affected by the additional monitoring information. |
