Embodiment Construction

[0049] The core of the present invention is to adopt the method of RPR to form a ring to make the Ethernet into a ring, construct the ring type Ethernet, and adopt the two-layer Ethernet MAC (media access control) address encapsulation format to realize the forwarding of the two-layer Ethernet data frame, and simultaneously The ring Ethernet has functions such as automatic topology discovery, fault detection, and fast protection.

[0050] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] The topology of the ring Ethernet is shown in Figure 1: it includes multiple network node devices R1, R2, R3, and R4, and adopts a double-ring structure. Adjacent network node devices are connected through a pair of reverse physical links. To transmit business data between network nodes. The business data...

Abstract

This invention discloses one ring Ethernet and its business load realization method, wherein, the ring Ethernet comprises multiple network points device connected by one reverse physical linkage, wherein, each point adopts special Ethernet type label tropical find data frame index ring structure to establish tropical image; in business loading, on business source point sealing Ethernet data into ring network data frame and sending to top ring Ethernet; ring each point transferring the images according to the tropical image; peeling off data on business aim point.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a ring Ethernet and a method for realizing service bearing thereof. Background technique [0002] At present, there are mainly two ring network technologies of Ethernet: EAPS (Ethernet Automatic Protection System) and RPR (Resilient Packet Ring). [0003] EAPS is used to provide fast protection for Ethernet ring topology. This mechanism is applicable to the Ethernet ring interconnection topology, and does not need to add new hardware and interfaces. EAPS treats a single ring as an EAPS domain. Any VLAN (Virtual Local Area Network) that needs to fail protection should be set up to include all ports on the ring, and then assign the VLAN to an EAPS domain. On the ring, one switch is designated as the master node, while all other switches are designated as transition nodes. One port of the master node connected to the ring is assigned as the master port of the maste...
