In an MPLS network (100), one or more monitoring probes (10, 20) are arranged to monitor data traffic on a particular path formed of several links (50) in the network. The monitoring information from the probes (10, 20) is then sent to a Network Management module (110) via links (70) in a path through the network (100) that avoids, so far as possible, any links (50) in the path being monitored, as well as any links (60) in paths that are considered to be important due to having high priority or that would be adversely affected by the additional monitoring information. |
