Embodiment Construction
[0037] The algorithm of the present invention is mainly executed on the switch, and appropriate switch chips need to be selected, such as 6095F, 6061F and other chips of Marvell, and BCM53242 and BCM53262 of Broadcom. The chip must have BPDU management frames, and a specific network driver needs to be written to process BPDU management frames. BPDU management frames are different from ordinary data frames, and the network driver can process these two different data frames at the same time. Optimize the network to increase the priority of BPDU data frames, open the QOS function of the switch, and set its priority to be the highest. At the same time, in order to ensure that the CPU has enough time and resources to process BPDU frames, you can configure the switch to limit the speed at which unknown multicast and broadcast packets flood into the CPU port.
[0038] When the switch is initialized, all ports are in the blocking state and send a link up message. If the message sent ...
