Problems solved by technology

[0004] However, with the continuous expansion of the communication network, there are more and more network devices. Once the data channel of a certain network device fails, it will trigger multiple network devices in the communication network to re-plan the relevant transmission paths. From the entire communication network From the point of view, the resulting re-planning of the transmission path requires a very large amount of calculation, and the re-convergence time of the entire communication network will be very long.

Embodiment Construction

[0039] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0040] In the traditional fault handling method, once the network device detects the failure of the data channel between two internal forwarding units, it will actively shut down all service interfaces on the forwarding unit. When other connected network devices sense the interface down event of this network device, they will block the communication with this network device and re-plan the transmission path so that the service tra...

Abstract

Embodiments of the present disclosure provide a fault handling method, device, network device, and machine-readable storage medium. The network device detects the data channel between every two forwarding units inside it. If fault occurs, the fault information will be sent to the neighbor network device. After receiving the fault information, the neighbor network device will block sending the destination address to the network device according to the fault information and the corresponding relationship between the internal forwarding information of the device and the destination address. The data packet of the first destination address, and re-plan the transmission path for the first destination address, wherein the fault information includes: the device ID of the network device and the channel ID of the data channel where the fault occurred, and the internal forwarding information of the device includes the device ID and channel ID. With this solution, rapid convergence of the communication network after a data channel failure inside the network device can be realized.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a fault handling method, an apparatus, a network device, and a machine-readable storage medium. Background technique [0002] In the current communication network, network equipment mostly adopts distributed architecture, such as figure 1 As shown, a network device includes a main control unit, a plurality of forwarding units, a control channel and a data channel. Each forwarding unit exchanges routing protocol information with the main control unit through the control channel. The main control unit calculates the optimal forwarding path according to the routing protocol information of each forwarding unit, and sends the calculation result to each forwarding unit, and each forwarding unit generates an indication locally. Forwarding entry for data packet forwarding. On each forwarding unit, the data packet enters from the inbound interface. By checking the...
