Embodiment Construction

[0015] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] It is necessary to respond immediately to the down of the port, because it is impossible to confirm whether the down is real or false. .

[0017] The present invention mainly focuses on the Up of the port, especially the situation where the port changes from Down to Up. Facts have proved that on a port with a poor link status, the port can go up / down thousands of times within 1 second. Frequent up / down of the port will cause network vibration and poor service quality.

[0018] For this deficiency, the present invention proposes a solution, by setting a confidence period to ensure the stability of the Up state, for example, the confidence period of a port can be set to 5 seconds, so only if the port is always Up within 5 consecutive seconds , the network device is notified that the port is Up if it has not been Down. If the port is Down again w...

Abstract

The invention provides a method and a device for improving the stability of network equipment. The method comprises the following steps: continuously detecting each port to detect whether a Down-to-Upevent occurs; if detecting that the Down-to-Up event occurs to a port, continuously detecting the port in a preset confidence cycle to judge whether an Up-to-Down event occurs to the port; if not detecting that the Up-to-Down event occurs to the port in the preset confidence cycle, informing an upper layer protocol stack of the port Up. Under the condition that a network physical link has a poorstate, the method lessens network faults caused by link-state shock to a maximum extent, and improves the network stability by a delayed network state-reporting mechanism.

Description

technical field [0001] The present invention relates to the field of data exchange, in particular to reducing network failures caused by link state oscillations to the greatest extent through a link state delay reporting mechanism when the physical link state of the network is poor, and improving network security. Method and apparatus for stabilization. Background technique [0002] Nowadays, the speed of network development is astonishing, and the stability of the network is also more prominent. For network devices (including routers, switches, etc.) Especially important. [0003] Many network services today are related to the opening or closing of physical ports (Up / Down). At this time, the port is Up, and some services need to be switched back to the restored link. [0004] From the simple example above, it can be seen that every Up / Down of a physical port will cause some adaptive changes in many running services. These changes are for emergency use. The port must be ...
