DISTRIBUTED METHOD AND SYSTEM FOR IMPLEMENTING LINK AGGREGATION CONTROL PROTOCOL (LACP) STANDARD STATE MACHINES

摘要

The present invention provides a distributed method for implementing Link Aggregation Control Protocol (LACP) standard state machines, wherein the method includes: after receiving a message, a physical port transmits it to a receive machine; the receive machine, a periodic transmission machine, a multiplexer (MUX) machine, and a transmit machine are triggered to operate in turn; the selection logic on a master controller is triggered to operate, and the processing of the message is completed according to the physical link selection state of the selection logic on the master controller; wherein, the receive machine, periodic transmission machine, MUX machine, and transmit machine operate on the link card at which the physical port is located, and the selection logic operates on the master controller. The present invention improves the operation efficiency of the LACP state machines, and enhances the reliability and stability of the operation of the LACP state machines.
