Embodiment Construction

[0040] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0041] The general idea of ​​the present invention is to provide a method and device for recovery and transmission of aggregated link faults, which are applied to network switches. The ports of the network switch are provided with aggregated links to transmit data. When an intermediate link in the aggregated link fails, the When data transmission cannot be carried out normally, private packets can be sent to each other through the network switches at both ends of the aggregation link, and the disconnected intermediate link can be determined according to the mutual response packets after receiving the private The link re-calculates the data transmission, transfers the data to the normal intermediate link for transmission, and realizes...

Abstract

The present invention provides a method and device for recovery and transmission of an aggregation link failure. When an intermediate link in the aggregation link fails, the network switches at both ends of the aggregation link send detection messages and response messages to each other. Both network switches can accurately find out the disconnected intermediate link, recalculate the transmitted data on the normal intermediate link, and switch the data sent by the corresponding port of the faulty intermediate link to the normal intermediate link Transport on the road. The present invention can quickly identify the faulty intermediate link without the intervention of the user, and quickly switch the data sent by the corresponding port of the faulty intermediate link to the normal intermediate link in the aggregation link for forwarding.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a method and device for recovering and transmitting aggregated link failures. Background technique [0002] In the actual application of the monitoring network, with the increase of media flow traffic and the need for long-distance transmission, the switch port in the network sends media flow through the aggregated link, in which the optical fiber transceiver or other transmission equipment will be used in the aggregated link. If the fiber optic transceivers in the aggregation link or the fiber cables between other transmission devices are disconnected, the data sent by the flow-sending switch may still go through the disconnected fiber after being hashed because the switch cannot detect it. , which will result in data loss. [0003] In the prior art, for the problem of disconnection of aggregated links, the LACP protocol is used to implement link switching...
