Abstract

The invention discloses a trusted video application method based on network measurement, relating to the technical field of the Internet. The trusted video application method is characterized in that a video service platform is built on the basis of a new generation of trusted Internet architecture, and safety and network measurement are integrated in one framework. According to the source address authentication technology, a trusted user is permitted to use the method to apply for certain high-performance applications at the platform and rejects unauthorized users; network measurement is carried out on a user subjected to source address verification, wherein the network measurement includes end-to-end link performance measurement and finer-granularity segmental measurement; and a network administrator can adopt a routing and resource adjusting strategy according to measurement results so as to satisfy the requirement of video application on link bandwidth and time delay. According to the trusted video application method, video application can be effectively applied and the reliability and the safety of the video application is ensured.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a trusted video application application method based on network measurement. Background technique [0002] High-performance video transmission systems (including video conferencing systems) with technical characteristics such as large data volumes and low delays are typical applications of the next-generation Internet. The application system itself puts forward high requirements. Currently popular video application systems include DVTS system, VLC system and high-definition uncompressed video system, with resolutions from standard definition (720×480) to high-definition (1920×1080), transmission bandwidth from 22Mbps to 800Mbps, with different characteristics, for users Provide different services for different needs. Due to the port speed limit, network congestion and other reasons, the current Internet may not be able to meet the bandwidth requirements of the video transm...
