The present invention provides for a method for Enhanced Equipment Protection Switch for Customer's device Dual-Homing, in an interconnection between a Central site/Pop and a Transport Network Hub by two boards. Each board is simultaneously connected to the Switching Matrix of the Transport Network Hub with B/2 bandwidth. Both boards receive the band B from the Central site/Pop, and send half a band B/2 directly to the Switching Matrix, and the other half band B/2 to the other board.

Method for the protection of the connection between a transport network hub and a central site/pop

Method of processing MPLS packets in a telecommunication equipment comprising the following steps in the following order:

Methods of processing data packets at layer three level in a telecommunication equipment

The present invention provides for a method and apparatus for an end-to-end connection between an RPR and an MPLS network, where the RPR network is linked to the MPLS network (and viceversa) through a TLS layer. In a preferred solution, the client layer is Ethernet, but any client layer can be considered.

Method and apparatus for end-to-end connection between an RPR and an MPLS network

Described is a method extending the OAM functionality in the RPR networks through a new OAM loopback procedure of request-reply type together with the definition of a new RPR OAM loopback frame. The OAM loopback function allows any RPR station to check the reachability of another RPR station. It is not necessary to stop any data traffic communication on the network in order to perform this function.
