[0053] In the first embodiment of the present invention, a tunnel packet loss detection method is composed of a head node, several intermediate nodes and a tail node to form a tunnel, such as figure 1 As shown, the process performed by the head node includes the following specific steps:

[0054] Step S101, the head node sends a set number of detection request messages to the intermediate nodes according to the set frequency, so that each intermediate node and tail node can count the number of detection request messages sent and received by itself, and then report the statistical results to the monitoring device ; The frequency of the setting is greater than the sending frequency of the Ping message adopted when checking the network connectivity and network speed but must be the upper limit with the transmission bandwidth of the tunnel, and the transmission bandwidth of the tunnel is usually defaulted to the communication device network side The transmission bandwidth of the p...

[0065] The second embodiment of the present invention is a tunnel packet loss detection method. The method of this embodiment and the method of the first embodiment all belong to the same technical idea. The difference is that this embodiment describes the present invention from the perspective of an intermediate node. Technical solutions.

[0066] The tunnel packet loss detection method of this embodiment consists of a head node, several intermediate nodes and a tail node to form a tunnel, such as image 3 As shown, the process executed by the intermediate node includes:

[0067] Step S201 , during the process of receiving and forwarding the detection request message, the intermediate node counts the number of detection request messages sent and received. The frequency at which the detection request message is sent from the head node of the tunnel conforms to the set frequency, and the set frequency is greater than the sending frequency of the Ping message used when checking...

Abstract

The present invention provides a tunnel packet loss detection method and device, and a network communication device. Through improvement of sending frequency of sending a detection request message through a head node and quantity statistics and report of transmit-receive message in each node in a tunnel, the tunnel packet loss detection method and device, and the network communication device can realize rapid and accurate tunnel packet loss detection, can be applied to a two-way tunnel and a one-way tunnel, can perform tunnel transmit-receive packet statistics of each node on a link, accurately determine the concrete packet loss position and quantity, rapidly locate the network fault points, provide convenient means for engineering maintenance and satisfy the requirement of network operation maintenance.

Description

technical field [0001] The present invention relates to the field of MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) network technology, in particular to a tunnel packet loss detection method, device and network communication equipment. Background technique [0002] Link packet loss detection is a common network maintenance function. Accurate and fast packet loss detection is extremely important for network maintenance. Currently, there are three main types of packet loss detection tools: [0003] The first category is OAM (Operations, Administration, and Maintenance, operations management and maintenance) tools. In the commonly used MPLS-TP (Multi-Protocol Label Switching Transport Profile, Multi-Protocol Label Switching Transport Profile) OAM LM (Frame Loss Measurement, packet loss detection) function, TMP (T-MPLS Path) layer, TMC (T -The LM function of the MPLS Channel) layer can only perform end-to-end packet loss detection based on the service pa...
