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 rapid ring protection protocol (RRPP)-ring-based traffic switching method and an RRPP-ring-based traffic switching device, which are applied to a traffic transmission process on the same RRPP ring. The method comprises the following steps that: after receiving a Link-Down message, a transmission node transmits current traffic in a broadcast way; and after receiving a Common-Flush-forwarding database (FDB) message from a main node, the transmission node receives updates a media access control (MAC) address forwarding table, and transmits the current traffic according to the updated MAC address forwarding table after the MAC address forwarding table is updated. By the method and the device, packet loss can be reduced in the traffic switching on the RRPP ring.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a flow 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 Ethernet rings. It can prevent the broadcast storm caused by the data ring when the Ethernet ring is complete, and can quickly restore the communication link between the nodes on the ring network when a link on the Ethernet ring is disconnected. Among them, the Ethernet ring refers to the Ethernet network topology of the ring connection, and 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 that have the same domain ID and control VLAN (Virtual Local Area Network, virtual local area network) and are connecte...
