State monitoring method and device for network port

A network port and status technology, applied in the direction of network interconnection, data exchange network, data exchange through path configuration, etc., can solve the problems of data packet loss, not maintaining the availability status information of remote tunnel endpoints, and not being able to perceive the tunnel status. To achieve the effect of preventing data loss

However, the GRE tunnel itself is a completely stateless design. The local tunnel endpoint does not maintain the availability status information of the remote tunnel endpoint. That is, when the remote tunnel endpoint is unreachable, the network node where the local tunnel is The tunnel sends data packets, forming a tunnel black hole, which will cause a large amount of data packet loss

Abstract

The invention provides a state monitoring method and device for a network port. The method comprises the following steps: transmitting a detection message to a destination based on a first time interval; and judging whether a response message of the destination is received within a second time interval, and if the response message is received, then resetting a receiving timer based on the second time interval, otherwise, generating and uploading unavailable status information of a current network port. The state monitoring method for the network port provided by the invention can effectively monitor whether the current network is available or not, and avoid data loss.

Description

Technical field [0001] The embodiment of the present invention relates to the field of network monitoring, in particular to a method and device for monitoring the state of a network port. Background technique [0002] GRE is a tunnel technology that can establish a virtual IP connection between two tunnel endpoints and encapsulate the original data message in a new tunnel message, thereby realizing the expansion of the layer 2 network and the creation of the layer 2 network. However, the GRE tunnel itself is a completely stateless design. The local tunnel endpoint does not maintain the availability status information of the remote tunnel endpoint. That is, when the remote tunnel endpoint is unreachable, the network node where the local tunnel is located cannot perceive the tunnel status and will continue to The tunnel sends data packets, forming a tunnel black hole, which will cause a large number of data packets to be lost. Summary of the invention [0003] The embodiment of the...
