Background
With the development of internet technology, more and more servers are connected to the network, so that the amount of data to be transmitted in the internet, that is, network traffic, is larger and larger. In this case, in order to prevent the network from being congested, in the prior art, different network traffic is generally shunted to different network links by a network traffic shunting method. Generally, a network traffic offloading method is to identify an application corresponding to a network traffic through a classification technique, and then offload the network traffic corresponding to different applications to a network link of the application corresponding to the network traffic based on an identification result of the application. Software deadlock, referred to herein as process deadlock, is a computer technology term. It is a state of operating system or software running: in a multitasking system, a deadlock is created when one or more processes wait for system resources, which are in turn occupied by the process itself or by other processes. Because the resource occupation is mutually exclusive, when a process applies for resources, the related process can never allocate necessary resources and can not continue to operate without the assistance of external force, and a special phenomenon is generated. The network traffic shunting method aiming at the software deadlock and high-load jump technology in the prior art does not exist.
