<p>A method of managing a multi-protocol label switched (MPLS) network out of band (OOB), the method comprising: indicating a MPLS traffic unit related to a management function by generating at a MPLS node in a MPLS communications network a said MPLS traffic unit having a MPLS header label field; assigning a predetermined label field value to said header label field, said value being known as being assigned in said MPLS network to indicate that said MPLS traffic unit relates to said management function; and propagating said MPLS traffic unit between a plurality of nodes of said MPLS communications network, whereby a receiving MPLS node when processing said MPLS header is able to determine from the predetermined label field value that said MPLS traffic unit comprises data relating to said management function.</p> |
