Abstract

The invention discloses a method and device for achieving tangent ring user data message intercommunication. In an RRPP ring, a first transmission node receives a second Hello message sent by a first main node, the second Hello message carries a first encapsulated VLAN ID, and the first encapsulated VLAN ID is any VLAN ID in first RRPP embodiments except the VLAN IDs controlled by transmission node public devices. A first transmission node starts a PBB function in an RRPP domain, and the first encapsulated VLAN ID in the Hello message is saved. A non-RRPP port of the first transmission node receives a data message sent by a user, a user VLAN ID of the data message is a control VLAN of a first RRPP ring, the first transmission node inquires a mapping table corresponding to a target MAC of the data message, conducts PBB encapsulation on the data message, and forwards the data message, wherein the target MAC in an encapsulated BMAC is an inquired bridge MAC in the corresponding mapping table, a source MAC is the bridge MAC of the first transmission node, a BVLAN is a first encapsulated VLAN ID, and an I-SID is a preset value. According to the technical scheme, the method and device for achieving the tangent ring user data message intercommunication can achieve intercommunication of the data message with the control VLAN between users.

Description

technical field

[0001] The invention relates to network communication transmission technology, in particular to a method and equipment for realizing intercommunication of tangent ring user data messages. Background technique

[0002] At present, technologies to solve the problem of layer 2 network loops include Rapid Spanning Tree Protocol (RSTP, Rapid Spanning Tree Protocol), Per-VLAN Spanning Tree (PVST, Per-VLAN Spanning Tree), Multiple Spanning Tree Protocol (MSTP, Multiple Spanning Tree Protocol) and Rapid Ring Protection Protocol (RRPP, Rapid Ring Protection Protocol). RSTP / PVST / MSTP applications are relatively mature, but the convergence time is at the second level. RRPP is a link layer protocol specially applied to Ethernet rings, and has a faster convergence speed than RSTP / PVST / MSTP. Moreover, the convergence time of RRPP has nothing to do with the number of nodes on the ring network, and can be applied to networks with large network diameters.

Embodiment 1

[0083] This embodiment takes figure 2 The schematic diagram of the RRPP tangent ring network shown in the figure is an example. The left configuration domain 1 control VLAN is 3-4 (the main control VLAN is 3, the sub-control VLAN is 4, and the default main control VLAN ID plus 1 is the sub-control VLAN ID ), the control VLANs of domain 2 on the right are 5-6, the protection instance VLANs of the left RRPP ring are 3-10, the protection instance VLANs of the right RRPP ring are 2-20, and the public equipment of the transit node in the middle belongs to the left The RRPP ring and the right RRPP ring, so the transit node public device in the middle has control VLAN3-6.

[0084] The ports between devices on an RRPP ring are RRPP ports, and the ports between devices and users on an RRPP ring are non-RRPP ports. In this embodiment, user 1 sends a data message of VLAN4 to user 2 as an example to illustrate the technical solution of the present invention, and on the premise that ther...
