Problems solved by technology

However, the network device cannot ensure that the Mux machine associated with the aggregation port of the peer network device of the network device is in the COLLECTING_DISTRIBUTING state
Therefore, in an actual application scenario, the aggregation link between the network device and the peer network device may have a situation where the aggregation port at one end is in the collection and distribution state, and the aggregation port at the other end is not in the collection and distribution state. As a result, packet loss occurs in business traffic

Embodiment Construction

[0045] Detailed descriptions will be given below through specific embodiments.

[0046] The LACP involved in this application can be found in the description of the Institute of Electrical and Electronics Engineers (English: Institute of Electrical and Electronics Engineers, abbreviation: IEEE) 802.1AX and IEEE 802.3AD, IEEE 802.1AX and IEEE 802.3A are incorporated by reference in their entirety. Applying. In the embodiments of this application, TRUE means "true" or "conditions are met". In computer coding, the value of TRUE can be "1"; FALSE means "false" or "conditions are not met". In computer coding, FALSE The value of can be "0". In the embodiment of the present application, UP indicates that the port is open or available, that is, the port is allowed to send and receive data packets; DOWN indicates that the port is closed or unavailable, that is, the port is not allowed to send and receive data packets. In the embodiments of the present application, "determining" may incl...

Abstract

A method, device and system for realizing a Mux machine. The method includes, the Mux machine of the aggregation port of the first network device is in the COLLECTING_DISTRIBUTING state, the aggregation port of the first network device is set to the collecting and distributing state, and the first network device starts a timer until The timer expires, the first network device determines that no LACPDU message indicating that the aggregation port of the second network device is in the collection and distribution state has not been received from the second network device, and the first network device will The Mux machine switches from the COLLECTING_DISTRIBUTING state to the ATTACHED state. Therefore, when the first network device determines that the Mux machine of the aggregation port of the second network device does not enter the COLLECTING_DISTRIBUTING state, it promptly switches the Mux machine of the aggregation port of the first network device from the COLLECTING_DISTRIBUTING state to ATTACHED state. The implementation mode of the present application realizes the detection and processing of the single-port UP of the aggregated link in the Mux machine in the coupled control mode, which helps to reduce the packet loss generated during the transmission process of the service flow.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to a method, device and system for implementing a multiplex (English: Mux) machine. More specifically, this application relates to a technology for implementing a Mux machine in a network running Link Aggregation Control Protocol (English: Link Aggregation Control Protocol, abbreviation: LACP). Background technique [0002] LACP provides a standard negotiation method for network equipment that implements data exchange. The network equipment at both ends of the LACP aggregation can automatically form an aggregation link according to its own configuration, and use the aggregation link to send and receive data. After the aggregation link is formed, the network devices at both ends of the aggregation link are responsible for maintaining the link status, and automatically adjust or dissolve the link aggregation when the aggregation conditions change. [0003] The LACP state machi...
