  • Methods of processing data packets at layer three level in a telecommunication equipment
    Patent number: 7480292
    Abstract: 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.

  • Programmable element of synchronous network and method for managing it
    Patent number: 7379482
    Abstract: Described is a SDH or SONET telecommunication network element provided with a plurality of interfaces for managing first SDH or SONET flows, comprising: a) a plurality of first layer ports for managing second SDH or SONET flows, wherein the ports are individually programmable as concerns the hierarchical structure of the managed flows, and b) a switching system coupled to the interfaces and to the ports, in order to implement the switching of virtual containers between the SDH or SONET flows, wherein the switching system is programmable as far as the switching to be implemented is concerned.
