Method and system for detecting end-to-end data transmission quality

Abstract

The invention provides a method and system for detecting the quality of end-to-end data transmission. By adding probe messages in the communication data stream, the encapsulation maintains three-layer standard encapsulation, and only the serial number is added in the data field without resorting to any Proprietary communication protocol, adding packet insertion, counting, and sampling methods at the entrance and exit of each device to realize the generation and statistics of probe messages, and realize agile monitoring of the transmission quality of business messages according to the reception of probe messages, and improve the basis The problem that the current technical means cannot quickly delimit the packet loss location of the service message realizes the rapid positioning of the packet loss problem of the end-to-end service message, and solves the problem that the current data communication network cannot quickly and easily deploy service-based end-to-end packet loss detection problem.

Description

[0001] The present invention relates to the technical field of network communication, in particular to a method and system for detecting end-to-end data transmission quality. Background technique [0002] Network stability is a difficult problem in the field of communication technology, which means that the data of one or more data packets (packets) cannot reach the destination through the Internet. Packet loss may cause jittering in streaming media technology, VoIP, online gaming and video conferencing, and will affect other online applications to a certain extent. There are currently three mainstream packet loss detection methods in the field of data communication technology, namely, transport layer packet loss detection based on TCP retransmission timer, three-layer forwarding scene detection, and application layer segmented deployment ping script detection. [0003] The transport layer packet loss detection method based on the TCP retransmission timer can only detect servi...

Problems solved by technology

The above-mentioned invention needs to modify the packet header of the real service message, insert a specific mark in the packet header of the service message, so as to realize the detection at the receiving end, but the method of directly modifying the packet header is both burdensome to the TM module and the PFE module. Relatively large, and modifying the packet header has a direct impact on the structure of the service message, and may be discarded in the form of an error packet on the device that does not recognize the header along the way; device, cannot be deployed on some low-end network devices or consumer-grade network devices

[0009] Based on the above analysis of existing technologies, there are the following problems: First, the transmission quality of service packets is mainly monitored through the TCP retransmission mechanism, and the transmission of UDP service packets cannot be effectively monitored; second, the current technology that supports end-to-end packet loss detection It is impossible to accurately locate the location of packet loss, and the technology that can accurately locate the location of packet loss does not support end-to-end deployment; third, the implementation mechanism of packet loss detection technology is complicated, and there are many internal calling modules. Compatible with consumer grade products and communication products with lower performance
