Problems solved by technology

[0004] However, in another case, the outbound interface is not down, but the business load is too large, and the packet flow is very large, which will seriously affect the speed of service implementation.
At this time, because the interface status is still up (up), the effective outbound interface selected by policy routing will not be switched to the backup interface, and this problem cannot be solved.

Embodiment Construction

[0022] The technical solutions of the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0023] figure 1 is a schematic diagram of a network device in an embodiment of the present invention, such as figure 1 As shown, the network device in this embodiment includes: a detection module and a switching module.

[0024] Wherein, the detection module is used to detect the traffic of the forwarded message of the first interface link, and when it is detected that the traffic of the forwarded message of the first interface link reaches a predetermined condition, a signal is output to the switching module; specifically, the detection module is used for Obtain the idle index of the first interface link forwarding the message, the idle index is the ratio of the idle bandwidth to the total bandwidth when the first interface link forwards the message, and when it is detected that the idle index is less than a predeterm...

Abstract

The invention discloses a method and a network device for switching interface links. The invention can regularly detect the current forwarding performance of the interface and switch routes according to the current forwarding performance of the interface link. The method is used in a network device capable of forwarding messages and comprises the following steps: detecting the flow rate of message forwarded by a first interface link; and when the flow rate of the message forwarded by the first interface link achieves a preset condition, switching the forwarded message to a preset second interface link.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and network equipment for realizing interface link switching. Background technique [0002] With the development of network technology, the application of IP technology in NGN (Next Generation Network, next-generation network), IPTV (Internet Protocol Television, Internet Protocol Television) and other service bearer fields, IP network from a simple Internet (Internet) , The data service bearer network has gradually become a data, voice, and video multi-service bearer network, and the traffic of network services has also continued to grow rapidly. In the practical application of policy routing, it is urgent to be able to switch the effective outbound interface of policy routing according to the traffic forwarding performance status of the current outbound interface, so as to ensure that various business applications will not be seriously affected when the traffic is lar...
