Abstract

The invention discloses a method and an apparatus for transmitting messages. The method comprises the following steps: a first PE device allocates a bypass PW for an AC corresponding to each CE device; the first PE device receives a first message to be transmitted to a target CE device; if the AC corresponding to the target CE device is out of order, the first PE device determines the bypass PW corresponding to the AC corresponding to the target CE device and sends the first message to a second PE device via the bypass PW, and the second PE device sends the first message to the target CE device. According to the method, the bypass PW is introduced to protect the AC so that the traffic of the CE device out of order in link can be forwarded normally.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a message transmission method and equipment. Background technique

[0002] In an MPLS (Multiprotocol Label Switching, Multiprotocol Label Switching) network, packets can be forwarded based on labels, providing a high-speed and efficient way for packets to be transmitted in the backbone network. VPLS (Virtual Private LAN Service, virtual private LAN service) is a typical application of MPLS, which can connect user sites belonging to the same VPN (Virtual Private Network, virtual private network) and located in different geographical locations through the backbone network of the service provider. has been widely used.

[0003] like figure 1 As shown in the figure, it is a schematic diagram of a VPLS network. The VPLS service is configured on PE1 (Provider Edge, service provider network edge), PE2, and PE3, and the primary VSI (Virtual Switch Instance) is configured...
