AI Technical Summary

Problems solved by technology

[0003] When faults occur frequently, the switch chip frequently reports the received CCM messages to the CPU, causing a large amount of CPU resources to be occupied, resulting in the inability to process other messages reported to the CPU in a timely manner.

Embodiment Construction

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0032] The chip-based method and device for realizing RDI disclosed by the present invention realizes the setting and clearing of the RDI flag bit through the chip, reduces the burden of the CPU, and improves message processing efficiency.

[0033] Such as figure 1 As shown, a chip-based method for implementing RDI, including

[0034] Receiving the CCM message, and judging whether the CCM message has the RDI flag bit, and updating the state of the chip to have a fault when the CCM message has the RDI flag bit;

[0035] Specifically, CCM packets are used to detect the connectivity of the link. In 802.1ag, the connectivity of the link is detected by periodically sending CCM packets. If three consecutive CCM packets are lost, the other party is considered unreachable. , that is, the li...

Abstract

The invention discloses a method and device for implementing RDI based on a chip. The method comprises the following steps: receiving a CCM message by the chip, determining whether the CCM message hasan RDI flag bit, and updating the status of the chip as that there is a fault existing when the CCM message has the RDI flag bit; when the status of the chip is that there is a fault existing, periodically sending the CCM message with the RDI flag bit to the remote end, and clearing the RDI flag in the CCM message by the chip after the fault is recovered. The method and device realize the settingand clearing of the RDI flag through the chip, with no need to report to the CPU to set and clear the RDI flag through the upper layer software, thereby reducing the burden on the CPU and improving the processing efficiency of the message.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a chip-based method and device for realizing RDI. Background technique [0002] RDI (Remote Defect Indication, Remote Defect Indication) is used to exchange fault conditions between the local MEP and the remote MEP. For example, the local MEP notifies the remote MEP after detecting a defect or fault, or the remote MEP detects a defect or After the fault occurs, the local MEP is notified. When a defect or failure occurs, in the receiving direction, the switch chip receives the CCM message with the RDI flag, and reports the CCM message to the CPU, and instructs the switch to perform corresponding operations through the upper layer software; in the sending direction, and in the fault During the continuous period, the RDI flag in the CCM message is set to 1 by the upper layer software, and after the fault is recovered, the RDI flag in the CCM message is also c...
