Abstract

The embodiment of the invention provides a method for preventing service interruption and network equipment. Middle network equipment actively detects whether the middle network equipment is subjected to protocol attack according to a detection period; because the detection period is shorter than protocol conversion interruption duration, the middle network equipment informs upstream network equipment that the middle network equipment is subjected to the protocol attack before service is actively removed due to abandonment of keep-alive messages, and the upstream network equipment timely switches the service to a standby path before service interruption, so that before the service interruption of the middle network equipment due to the protocol attack, the upstream network equipment switches the service from a main path to the standby path to avoid the service interruption.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and network equipment for preventing service interruption. Background technique [0002] With the development of the Internet, the network environment is becoming more and more complex, and network attacks are becoming more and more frequent. Flooding attacks are a common network attack. Flooding attacks send a large number of protocol packets to network devices in a short period of time. The processor (Central Process Unit, referred to as CPU) is responsible for processing various protocol packets, but the processing capability of the CPU is limited, that is, the rate of protocol packets that can be processed is limited. If there is a network attack that causes the protocol packets received by the CPU to exceed the The processing capability of the CPU may cause normal packets not to be processed and service interruption may occur, or it may cau...
