Embodiment Construction

[0036] The improvement of the present invention to the continuity detection mechanism in the prior art lies in the deactivation step. When the source-end MEP receives the deactivation instruction sent by the operation and maintenance personnel, it starts to periodically send the time-to-live TLV to the sink-end MEP and set it to 0 When the sink MEP receives the CCM message whose TLV is 0, it sends a CCR (Continuity Check Reply) response message to the source MEP, and the source MEP only receives After the sink MEP sends a CCR response packet, it stops sending CCM packets with a TLV of 0 and performs subsequent processing. In this way, when the faulty link is restored, the sink MEP can avoid the failure of receiving CCM packets with a TLV of 0. False alarms caused by messages.

[0037]The present invention will be described in detail below in conjunction with the accompanying drawings. The present invention improves the deactivation step without changing the original activation...

Abstract

The invention relates to a method for controlling the continuous detection on Ethernet chain. Wherein, said method comprises: when the source maintain end of chain receives the inactive instruction for stopping continuous detection, starts to periodically send continuous detection report with detection information to the host maintain end; when the host end receives said report, it feedbacks response eject report to the source end and stops the continuous detection; when the source end receives said eject report, it stops sending continuous detection report and ejects detection. With said invention, the continuous detection will not be lost and the alarm can be eliminated on time, when the network error is recovered from accidence.

Description

technical field [0001] The invention relates to the Ethernet, in particular to the detection and maintenance technology of the Ethernet, and discloses a method for controlling the continuity detection of the Ethernet link. Background technique [0002] At present, in the Ethernet end-to-end OAM (Operations, Administration and Maintenance) mechanism, continuity check (CC, Continuity Check) is usually used for automatic discovery of network faults, and ITU-T (Institute of Electrical and Electronics Engineers, Institute of Telecommunications Electronics Engineers) and IEEE (International Telecommunication Union, International Telecommunications Union) both groups have conducted research on this. [0003] Ethernet network failures may be caused by link failures, loops, and software configuration errors. The continuity detection mechanism provides a method that can detect both hardware failures and software failures such as memory exhaustion and configuration errors. Continuity ...
