Problems solved by technology

[0014] The first purpose of the present invention is to provide a method for preventing logical topology oscillation, in order to solve the existing network equipment, such as the logical topology oscillation and the logical topology oscillation that occurs when the switch cannot normally receive BPDU and / or VRRP messages under high load conditions. Problems such as network paralysis and instability are caused, and the logic topology oscillation is prevented under the condition of high equipment load, and the stability of the network is improved. If BPDU and VRRP messages cannot be received normally, the topology of STP and VRRP will not be oscillated.
[0015] The second object of the present invention is to provide a switch, which is used to solve the problems of logical topology oscillation and network paralysis and instability caused by the failure of the existing switch to receive BPDU and / or VRRP messages under high load conditions. , realize the prevention of logical topology oscillation under the condition of high load of the switch, and improve the stability of the network

Embodiment Construction

[0039] Referring to FIG. 8 , it is a flowchart of Embodiment 1 of a method for preventing logic topology oscillation according to the present invention. This example includes:

[0040] Monitoring the load utilization of the equipment itself and / or adjacent equipment;

[0041] Obtain whether the equipment itself and / or adjacent equipment are in an overload state according to the detection results;

[0042] When the device itself and / or adjacent devices are in an overload state, keep the logical topology state of the device unchanged, otherwise allow the logical topology to oscillate.

[0043] In the operation of obtaining whether the equipment itself and / or the adjacent equipment is in an overload state according to the detection results in the method, it is also possible to continue to detect the load utilization of the equipment itself and / or the adjacent equipment at the same time; keep the logical topology state of the equipment unchanged. During the operation, the operat...

Abstract

Said method comprises: detecting the load utilizing state of current device and / or its neighboring devices; according to the detection result, knowing that if the current device and / or its neighboring devices are at overload state; if yes, keeping the logical topology state of device unchangeable.

Description

technical field [0001] The present invention relates to a method for preventing logical topology from oscillating, especially a method for keeping logical topology from oscillating under high network load and improving network stability; A switch for keeping the logical topology of the network from oscillating under load conditions belongs to the technical field of communication. Background technique [0002] Network topology is divided into physical topology and logical topology. The physical line connection relationship between network devices is called the physical topology, and how packets flow on these connection lines is called the logical topology. [0003] A loop means that one device can be connected to another device through two paths. Usually, the line connection between two devices forms a ring physical topology. As shown in Figure 1, port 1 of switch A is connected to port 1 of switch B, and port 2 of switch A is connected to port 2 of the switch. In this way,...
