Problems solved by technology

[0016] Although this scheme can find the failure of the receiving device on the communication node and the failure of the communication link, it does not specify how to notify the user of the found failure.
At the same time, it is also impossible to identify the failure of the communication node itself
The failure of the communication node itself refers to the failure of the core software or hardware inside the communication node, resulting in the failure of the entire communication node to operate normally.

Embodiment 1

[0035] The schematic diagram of the principle of setting the management node for the Ethernet communication system provided by this embodiment is as follows figure 1 shown. exist figure 1 Among them, the first communication node and the second communication node are two communication nodes establishing a business communication relationship, and the Ethernet full-duplex link between the first communication node and the second communication node can be regarded as two bidirectional simplex aisle. Each channel consists of a RX, TX (Transmitter, transmitter) and a unidirectional link.

[0036] Configure a management node for the above-mentioned first communication node and second communication node, and the management node communicates with the first communication node and the second communication node respectively through different management dedicated channels, and the management dedicated communication channel is not controlled by the first communication node. 1. The influen...

Embodiment 2

[0040] In this embodiment, if the first communication node detects frame error and wrong symbol failure in its receiving direction, and detects that the heartbeat detection between the second communication node and the second communication node is normal, the first communication node reports its reception to the management node. The schematic diagram of link quality failure is as follows: image 3 shown. In this case, the first communication node may determine that neither the RX of the first communication node nor the TX of the second communication node is faulty, and the quality of the link in the receiving direction of the first communication node is problematic. Then, the first communication node sends a general event notification to the second communication node, so as to notify the second communication node that the receiving link quality of the first communication node is faulty.

[0041]The first communication node reports the failure of the receiving link quality of ...

Embodiment 3

[0043] In this embodiment, if the first communication node does not detect its own RX failure, but detects that the heartbeat detection with the second communication node fails, the first communication node reports to the management node that its receiving link is interrupted. Schematic such as Figure 4 shown. In this case, the first communication node can conclude that the link in its receive direction is broken. After the receiving link of the first communication node is interrupted, the first communication node will not receive any notification or data sent by the second communication node, and when the quality failure of the receiving link occurs at the first communication node, the first communication node detects Wrong frame and wrong symbol faults to own receive direction. Then, the first communication node sends a fatal event notification to the second communication node, so as to notify the second communication node that the receiving link of the first communicatio...

Abstract

The invention provides a fault handling method and a fault handling device for Ethernet. The method mainly comprises that: a management node receives fault information reported by communication nodes at two ends of an Ethernet link; the management node acquires the fault information of the Ethernet link and the communication nodes at two ends according to the fault information and the heartbeat detection information between the communication nodes at the two ends of the Ethernet link. In the embodiment of the invention, the special management node is set and a special management communication channel is used to monitor the states of the communication nodes, so the communication link fault information and the communication node fault information in the Ethernet can be acquired and differentiated effectively; and thus, quick fault clearing can be performed conveniently.

Description

technical field [0001] The invention relates to the technical field of Ethernet communication, in particular to a method and device for processing faults in the Ethernet. Background technique [0002] With the continuous development of Ethernet in MANs and WANs, operators pay more and more attention to OAM (Operations Administrations and Maintenance, maintainability) of Ethernet devices and links. [0003] Existing OAM solutions focus on the management and maintenance of point-to-point Ethernet links, providing a complete Ethernet OAM solution. As an optional sublayer of the MAC (Media Access Control, Media Access Control) layer, the OAM sublayer provides an effective mechanism for monitoring the link operating status when it is in effect, and can be applied to any full-duplex, A point-to-point Ethernet link, or a simulated point-to-point Ethernet link. [0004] In the existing OAM solution, link fault indication and location are performed through fatal event notification ...
