A NETWORK ELEMENT AND PACKET FORWARDING NETWORK ELEMENT WITH TRAFFIC MIRRORING FUNCTION, AND CORRESPONDING METHOD

A network element (101; 201; 611) of a data packet network (100) comprises a traffic mirroring filter (112) configured to filter data packets and to forward data packets that match the traffic mirroring filter (112) to an analysing network element (103; 621). The network element (101; 201; 611) furt...

description A network element (101; 201; 611) of a data packet network (100) comprises a traffic mirroring filter (112) configured to filter data packets and to forward data packets that match the traffic mirroring filter (112) to an analysing network element (103; 621). The network element (101; 201; 611) further comprises a data packet tagging module (113) to tag a data packet that matches the traffic mirroring filter (112) with a mirroring tag and to forward that data packet without duplication to thereby postpone duplication of that data packet to a packet forwarding network element (615) located at a point in the network where a trajectory of that data packet to its destination (102; 603) and a trajectory of that data packet to the analysing network element (103; 621) diverge.
