Abstract: An exemplary method and apparatus are provided for exchanging information for establishing a path between a first node and a second node of a communication network. The first node and the second node are adapted to send continuity check messages to monitor the established path. The technique includes generating, at the first node and at the second node, at least one link state message according to a routing protocol; inserting continuity check link state information into the at least one link state message; and exchanging between the first node and the second node, the link state messages for computing the path. The continuity check link state information are indicative of at least one rate of transmission of the continuity check messages supported by the first node and the second node.

Abstract: An exemplary method and apparatus are provided for data transmission in an optical transport network that includes receiving client data from a client, mapping the client data into a frame structure, mapping the frame structure into tributary slots of a data transport structure, and transmitting the data transport structure. The data transport structure contains a fixed number of tributary slots and the size of the frame structure is selectable in granularity of the tributary slots of the data transport structure.

Abstract: It is disclosed a method for data transmission in an optical transport network, comprising the steps of receiving client data from a client, mapping said client data into a frame structure (ODU-flex), mapping said frame structure (ODU-flex) into tributary slots (TS) of a data transport structure (HO-ODU), transmitting said data transport structure (HO-ODU), wherein said data transport structure (HO-ODU) contains a fixed number of tributary slots (TS), and wherein the size of said frame structure (ODU-flex) is selectable in granularity of said tributary slots (TS) of said data transport structure (HO-ODU).

Abstract: 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.

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.

Abstract: The method allows to share, within a network element of a telecommunication network, routing information deriving from a first routing source; the network element is of the type comprising a management agent provided with a management information database, wherein different routing information deriving from different routing sources is stored in different routing databases within the network element; according to the method, the management agent performs the steps of: a) receiving from a management manager route mapping information; b) storing into the management information database route mapping information corresponding to the received route mapping information; and c) retrieving and using the stored route mapping information for exporting said routing information from a first routing database of the first routing source and importing it into a second routing database of a second routing source.

Abstract: The present invention provides for a method for mapping MPLS packets over Synchronous Digital Transport Networks (SDH/SONET) or Optical Transport Networks (OTN) via GFP mapping layer, through a modified PPP protocol without the LCP and NCP protocols for negotiation. In the modified PPP protocol the MPLS or IP packets are inserted, and then the GFP header is added. In order to map the modified PPP over GFP a new UPI (User Paylod Identifier) value is defined in the GFP Core header.

Abstract: Method to set-up a transparent LAN-to-LAN functionality connection between a first multicustomer source location and a second multicustomer destination location through a RPR data transport network, said method comprising the steps of: receiving an Ethernet frame from a customer interface; processing in a conventional manner the Ethernet frame received; adding an auxiliary header to form a TLS frame; and adding to the resulting TLS frame a RPR header to form a RPR data transport frame for the RPR network. The auxiliary header comprises information about the channel designed to transport the RPR frame from the source node input interface to the destination node output interface.
