Method of processing MPLS packets in a telecommunication equipment comprising the following steps in the following order: incoming direction: count received frames and octets, validate packets, determine interface identification, count received packets and octets, strip external header, lookup for destination of incoming packets, next layer decision and forwarding, TTL management, if next-hop is not the equipment, PHB determination; outgoing direction: extract TTL from received outgoing client packets, forward received outgoing client packet as stripped MPLS packet with FEC, PHB, TTL, generate End_of_Stack bit, forward stripped MPLS packet with FEC, PHB, TTL, End_of_Stack lookup for destination of outgoing client packets with FEC originated by the equipment, TTL management create MPLS header, count transmitted packets and octets, forward MPLS packet, PHB, Next Hop.
