Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] A kind of method of the present invention enables Ethernet ring protocol and spanning tree protocol to be able to heterogeneous hybrid networking comprising the following steps:
[0020] (1) By setting the bridge priority attribute of the spanning tree protocol node, the root node of the spanning tree topology is fixed on the shared link of the coupling topology;
[0021] (2) All non-shared nodes on the dedicated ring network protocol enable the transparent transmission of spanning tree protocol packets, that is, the spanning tree BPDU packets received from a ring network port are not processed but are transmitted from the other paired ring network as they are. port forwarding;
[0022] (3) All nodes (usually the master node) on the dedicated ring network protocol receive the spanning tree protocol BPDU from the port actively blocked by themse...

The present invention discloses a method and system for enabling heterogeneous hybrid networking of the Ethernet ring protocol and the spanning tree protocol, comprising the steps of: (1) setting the spanning tree protocol node's bridge priority attribute to the root node of the spanning tree topology Fixed on the shared link of the coupled topology; (2) All non-shared nodes on the dedicated ring network protocol open the transparent transmission of spanning tree protocol messages; (3) All nodes on the dedicated ring network protocol are actively blocked from The disconnected port receives the spanning tree protocol BPDU and discards it; (4) The node on the shared link receives the spanning tree protocol BPDU from any one port of the two ring network ports and regards it as being received from the same port. The system of the present invention includes exchange chips and CPUs connected to each other, and the advantage of the present invention is that it realizes various forms of complex networking modes such as coupled multi-ring hybrid networking, ring and star network hybrid networking, and multi-homing hybrid networking. .
Description
technical field [0001] The invention relates to a method and system for heterogeneous mixed networking of the Ethernet ring protocol and the spanning tree protocol, belonging to the field of network technology. Background technique [0002] At present, the traditional Ethernet ring network is a ring topology composed of a group of IEEE 802.1-compatible Ethernet nodes. Each node is connected to two other nodes through a ring port based on 802.3 Media Access Control (MAC). Ethernet MAC can Carried by other service layer technologies, all nodes can communicate directly or indirectly. The physical topology of a separate Ethernet ring (hereinafter referred to as a single ring) is a ring redundant network topology. In order to avoid the formation of broadcast storms, the logical working network topology of the Ethernet ring is actually a chain, that is, the spanning tree of the single ring topology . At the same time, Ethernet rings can also be interconnected to form a multi-rin...
