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...
