Embodiment Construction

[0063] The embodiments of the present invention aim at the problems existing in the prior art, by improving the stream transmission mode and the MAC address learning mechanism for monitoring the transmission nodes on the RRPP ring, so as to achieve no packet loss when the circuit breaks, no packet loss when the MAC address forwarding table is updated, and The RRPP master node is transparent, avoiding repeated modification of network devices, so as to realize fast switching of RRPP ring traffic.

[0064] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0065] see figure 2 , which is a schematic diagram of the traffic switching process based on the RRPP ring provided by Embodiment 1 of the present invention. This process is applicable to the process of traffic switching between the transmission nodes on the same RRPP ring on the ring. As shown in the figure, when a link occurs When a fault occurs, the trans...

Abstract

The invention discloses a traffic switching method and device based on an RRPP ring, which is applied to the traffic transmission process on the same RRPP ring. The method includes: after the transmission node receives the Link-Down message, it sends the current traffic in a broadcast mode; the transmission The node updates the MAC address forwarding table after receiving the Common-Flush-FDB message sent by the master node, and sends the current traffic according to the updated MAC address forwarding table after the MAC address forwarding table is updated. By adopting the invention, packet loss can be reduced during traffic switching on the RRPP ring.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a traffic switching method and device based on an RRPP ring. Background technique [0002] RRPP (Rapid Ring Protection Protocol, Rapid Ring Protection Protocol) is a link layer protocol specially applied to an Ethernet ring. It can prevent the broadcast storm caused by the data loop when the Ethernet ring is complete, and can quickly restore the communication link between each node on the ring when a link on the Ethernet ring is disconnected. The Ethernet ring refers to a ring-connected Ethernet network topology. The ring in the RRPP domain is divided into a main ring and a sub-ring. figure 1 A single-ring RRPP networking structure is shown. [0003] The basic concepts of RRPP mainly include: [0004] -RRPP domain: switches with the same domain ID and control VLAN (Virtual Local Area Network, virtual local area network), and interconnected switches form a...
