Abstract

The invention provides a state detection method and device. The state detection method comprises the steps of sending a PDP (Port Detect Protocol) detection message sent by an appointed progress at a detected device; receiving a PDP response message returned by the detected device; and carrying out state detection on the appointed progress based on the received PDP response message. In the state detection method, as whether the appointed progress at a target device is alive can be detected, the problems in the prior art can be solved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for state detection. Background technique [0002] In order to protect key applications, certain redundant backup links are designed in the network. When a network failure occurs, network devices can quickly detect the failure and switch traffic to the backup link to speed up network convergence. [0003] The existing technology can detect whether the target device is running normally, but cannot detect whether the specified process on the target device is running normally. Therefore, when a fault occurs in the network, the existing technology can only locate the fault to the target device, but cannot accurately locate the fault to a specific process on the target device. Contents of the invention [0004] In view of this, the present application provides a method and device for state detection to solve the problem that the existing t...
