Example Embodiment

[0035] Specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are only used for illustration, and are not used to limit the present invention.

[0036] The embodiment of the method for realizing the automatic configuration of the Ethernet ring network in the present invention Figure 2A As shown, including steps Step201~Step 206:

[0037] Step 201. The major ring node configured with edge ports sends a campaign request message carrying a unique identification code corresponding to the node to the opposite end through each major ring port;

[0038] This embodiment implements the automatic configuration of the Ethernet ring network. First, the election of edge nodes and auxiliary edge nodes is completed by a competition mechanism. As for the election criteria, an identification code that can uniquely correspond to each main ring node must be selected. For example, each device can be selected. The bridge M...

Abstract

The invention discloses a method and a main link device for realizing automatic configuration of an Ethernet ring. The method comprises the following steps: transmitting a campaign request message among main links to realize the automatic election of a fringe node and an assisted fringe node; transmitting a subring topological collection message from a fringe port by using the configured fringe node, and returning the modified subring topological collection message by the configured assisted fringe node so as to automatically collect the subring topological message and realize the automatic configuration of the ring set. Based on the configuration information of the ring set, the fringe node can decide the blocking operation of the port according to the information when receiving the mainring fault noticing message of the assisted fringe node so as to prevent the looping of the ring set and ensure the maximum connectivity of the nodes.

Description

technical field [0001] The invention relates to the technical field of the Ethernet ring network, in particular to a method for realizing the automatic configuration of the Ethernet ring network and a master ring node device. Background technique [0002] RRPP (Rapid Ring Protection Protocol) is a link layer protocol specially applied to the Ethernet ring network. The Ethernet ring network using this protocol can prevent broadcast storms caused by data loops, and when an Ethernet ring network When the link is disconnected, the backup link can be activated quickly to restore the communication link between the nodes on the ring network. [0003] According to RRPP regulations, a group of devices configured with the same domain ID (identification) and the same control VLAN (virtual local area network) and connected to each other constitute an RRPP domain, and each device in it is called a node. An RRPP domain can include a single RRPP ring or multiple RRPP rings connected to ea...
