A pseudo wire label reflector, based on a existing label distribution router, further includes: a mode management unit, for determining the mode for switching and transferring a pseudo wire label message; a first session management unit, for saving the support information that LDP signaling session connection supports the pseudo wire label reflecting capacity; a first pseudo wire label receiving unit, for receiving a pseudo wire label message; a first pseudo wire management unit, for saving the switched pseudo wire state and deciding whether to modify the pseudo wire label message according to the switch and transfer mode determined by the mode management unit; a first pseudo wire label sending unit, for sending the pseudo wire label message. The invention also provides an edge apparatus and a L2 VPN. The present invention makes PE equipments participating pseudo wire service to set up PSN tunnel and LDP signaling session connection with the pseudo wire label reflector by introducing the pseudo wire label reflector and extending the capacity that the current edge apparatus supports the pseudo wire label reflector.

Pseudo wire label reflector, an edge equipment, and a two-layer virtual network

The present invention discloses a method for implementing fast multicast and a system thereof. The system comprises multicast protocol, forwarding plane and fast multicast control plane, and the fast multicast control plane further comprises management module and agent module. The method comprises steps of: determining an edge node of time domain overlapping sub-tree of corresponding multicast tree in the multicast service according to the analysis of time domain; initiating the static multicast member of multicast service on said edge node, so that an interface at which the static multicast member is initiated generates a requirement for multicast service; generating the multicast overlapping sub-tree from said edge node to a multicast root node, so that the multicast service flow is transmitted to said edge node in advance; after sending out the requirement for the multicast service flow through any receiver at said edge node, multicast tree path establishes a multicast forwarding tree from the receiver to the edge node, the multicast service flow will be transmitted from this edge node to the receiver. The present invention can effectively reduce the delay of multicast application.
