Abstract: Disclosed are a multicast data forwarding method and device supporting a virtual terminal. The method includes: a bridge forwarding module receiving multicast data sent by an end station and determining output ports; when a certain output port is the same with the input port of the multicast data and the input port has enabled reflective relay function, not carrying Ingress extended channel identifier (Ingress_E-CID) in the forwarded message information or the value of the Ingress_E-CID being zero. By modifying the source port filtering mechanism, the present invention enables a Port Extender (PE) supporting the virtual terminal technology to transmit and receive data normally while multicasting.

Abstract: This disclosure discloses a method for implementing protection group overlay and a method for implementing Ethernet protection switching based on the protection group overlay. The method for implementing Ethernet protection switching based on the protection group overlay comprises: when the fault of TESI is detected by multiple IPG which protect the same TESI, only one IPG of the multiple nested IPGs performs protection switching. This disclosure further discloses a system for implementing Ethernet protection switching based on the protection group overlay, comprising a protection switching performing unit, configured to when a fault of a TESI is detected by multiple IPGs which protect the TESI, only one IPG of the multiple nested IPGs performing protection switching. Application of the method and system of this disclosure implements protection for key protected path through protection group overlay, and can achieve effects of saving network resource and increasing utilization rate of network resource.
