摘要： A method is disclosed for provisioning loop free H-VPLS traffic service in a multi-domain MPLS network having interconnected domains. The method comprises: provisioning pseudo wires (PWs) for MPTMP services in each domain of the MPLS network; defining multiple Split Horizon Groups (SHGs) in the network, wherein each SHG corresponds to a domain, for the H-VPLS service traffic and for each specific node of the MPLS network, automatically assigning indications to SHG and the pseudo wires connected to the specific node, wherein the same indication is assigned to all pseudo wires belonging to the same group (SHG-N), and wherein the step of assigning is characterized in that when traffic belonging to H-VPLS service crosses a border network node located between two interconnected domains, the SHG-N indication of PWs remains the same within a VPLS domain thereby preventing the service traffic from returning to the domain of origin.

摘要： A reconfigurable wavelength selective dispersion compensation device RWSDCD for selective compensation of dispersion in optical channels having different wavelengths. The RWSDCD comprises a controllable wavelength selective unit WSU having a plurality of local, wavelength related input/output (I/O) ports. The RWDSD also comprises a dispersion compensation cascade comprising at least one chain of successively connected dispersion compensation units DCUs, wherein one or more of the DCUs in the chain are respectively connectable to one or more of the local I/O ports. The RWSDCD outputs one or more of the incoming optical channels upon selectively compensating chromatic dispersion in them, by controllably passing these channels via one or more DCUs of the dispersion compensation cascade.

摘要： A technique for testing peer nodes in a multicast domain (such as an access network) interconnected with an Ethernet network via an Intermediate Bridge (IB), especially helpful when an individual MAC address of a destination peer node is unknown. The technique comprises a) issuing a Connectivity Fault Management (CFM) message from the Ethernet network, and introducing into the CFM message alternative destination data being different than the individual MAC address of the destination peer node; b) utilizing the alternative destination data, at the IB, for determining topological position or address of the destination peer node, and c) forwarding contents of the CFM message only to the destination peer node.
