Service provider Ethernet loop detection and loop disposing method

Abstract

The invention provides a novel service provider Ethernet loop detection and loop disposing method. The service provider initiates loop detection at ports of an access node and a aggregation node and filters a detection message on a core node side corresponding to the aggregation node; the access node or the aggregation node makes a loop alarm after detecting the loop and performs loop disposing; the loop disposing comprises measures of closing a port and opening after waiting and the measure of filtering and aggregating the detection message by the access node. The service provider Ethernet loop detection and loop disposing method comprises that: the port of the access node initiates loop detection; the port of the aggregation node initiates loop detection; a core node port filters the detection message; the access node makes the loop alarm after detecting the loop and disposes the loop; the aggregation node makes the loop alarm after detecting the loop and performs disposing on the loop. The service provider Ethernet loop detection and loop disposing method enables the service provider Ethernet to effectively detect the loop through unique control on the processes, then performs alarming and disposing on the loop and then requires to check whether the loop disappears according to waiting time.

Description

technical field [0001] The invention relates to the field of carrier Ethernet, in particular to a novel carrier Ethernet loop detection and loop handling method. Background technique [0002] The development of Ethernet technology has brought about the technical upgrade of carrier networks. PBB (Carrier Backbone Bridge) technology is an Ethernet technology based on Mac-in-Mac encapsulation. By introducing I-SID and encapsulating MAC addresses, the scalability of the network is realized. Carrier Ethernet combines Ethernet technology with carrier networks to achieve high-bandwidth and highly reliable access, high-quality network protection, and convenient network management. [0003] Carrier Ethernet, as the bearer network of carriers, undertakes networking services for a large number of users. Due to the uncontrollability of the network environment at the user end, once a loop occurs at the user end, broadcast data packets will be forwarded cyclically in the loop, eventuall...

AI Technical Summary

Problems solved by technology

Due to the uncontrollability of the network environment at the user end, once a loop occurs at the user end, broadcast data packets will be forwarded cyclically in the loop, eventually causing a broadcast storm, resulting in a sharp decline in the performance of ports, links, and even nodes, resulting in Network blocking failure

On the node side of the local end, due to the negligence of the construction personnel at the local end or the failure of the equipment itself, it may also cause a loop phenomenon
