Embodiment Construction

[0018] In the embodiment of the present invention, RRPP is a link layer protocol specially applied to the Ethernet ring. This protocol can prevent the broadcast storm caused by the data ring when the Ethernet ring is complete; and when a link on the Ethernet ring is disconnected, it can quickly activate the backup link to restore the communication between the nodes on the Ethernet ring.

[0019] An Ethernet topology of ring connections to which RRPP is applied is called an RRPP ring, and multiple RRPP rings form an RRPP domain.

[0020] The master node is the main decision-making and control node on the RRPP ring. Each RRPP ring must have one and only one master node, and the transit node is a node other than the master node on the RRPP ring.

[0021] Among the two ports connecting the master node and the transit node to the Ethernet ring, one is the master port and the other is the slave port. The role of the port is determined by the user's configuration. The primary port ...

Abstract

The invention provides a service switching method for a ring network, which is applied in an RRPP (Rapid Ring Protection Protocol) ring composed of transmission nodes and a master node. The method comprises the steps that forwarding relation information is renewed after status transformation information of the rapid ring protection protocol ring is obtained and according to the rapid ring protection protocol ring, an ARP (Address Resolution Protocol) item is renewed according to the renewed forwarding relation information, and the protocol item is analyzed on the basis of the renewed address to perform the forwarding of service message. Through the utilization of the service switching method, the time for renewing the ARP item by the nodes and the delay of the three-level forwarded service switching of the RRPP ring can be reduced.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a ring network service switching method and device. Background technique [0002] Ring network technology, in simple terms, is a technology that connects some network devices together through the shape of a ring to achieve mutual communication. Existing ring network technology: such as Spanning Tree Protocol (STP, Spanning Tree Protocol). When the inventor realizes the present invention, he finds that the prior art has at least the following defects: the topology convergence speed is fast (higher than 50 ms) and the convergence time is related to the number of nodes on the ring network. Contents of the invention [0003] The embodiment of the present invention provides a ring network service switching method and device, so that the delay of the ring network service switching can be shortened. [0004] The purpose of the embodiments of the present invention is achieved thr...
