Embodiment Construction

[0123] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0124] The present invention aims at the problems of high cost, low precision, and small application range in the information processing scheme for packet loss data detection in the existing technology, and provides an information processing method, which is applied to the first tunnel endpoint network element, such as figure 2 shown, including:

[0125] Step 21: Send the first two-way active measurement protocol TWAMP message to the second tunnel endpoint network element;

[0126]Step 22: After sending the first TWAMP message, send a second TWAMP message to the second tunnel endpoint network element; wherein, the first TWAMP message carries the first TWAMP message to send The first number of previously sent packets; the second TWAMP packet carries a s...

Abstract

The invention provides an information processing method and device and a tunnel endpoint network element, and the information processing method comprises the steps: transmitting a first TWAMP message to a second tunnel endpoint network element; after the first TWAMP message is sent, a second TWAMP message is sent to the second tunnel endpoint network element; wherein the first TWAMP message carries a first number of messages which have been sent before the first TWAMP message is sent; the second TWAMP message carries a second number of messages which have been sent before the second TWAMP message is sent. According to the scheme, the problems that in the prior art, an information processing scheme for packet loss data detection is large in expenditure, low in precision, small in application range and the like are well solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an information processing method, device and tunnel endpoint network element. Background technique [0002] At present, SD-WAN (software-defined wide area network) is forwarded based on Overlay (overlay) tunnels. The tunnel is a point-to-point connection, which greatly simplifies the acquisition of packet loss rate, and there are multiple tunnel packet loss detection methods , mainly involving the following two types: [0003] The first method is to send detection packets, and check the loss rate of the detection packets to infer the packet loss rate; however, for this method, it needs to spend the bandwidth overhead and processing overhead of the measurement packets, and the measurement packets may not be able to cover All underlying load sharing links (such as figure 1 As shown in the network structure, there may be situations that cannot be covered), so the pac...
