Audio and video system, access method, routing and forwarding method, and readable storage medium

Abstract

The invention discloses an audio and video system, an access method, a routing forwarding method and a readable storage medium. The audio and video system includes an audio and video cloud network and an operator network, wherein the audio and video cloud network includes: a control center, including a dispatch center and routing center; media nodes, including transit nodes and edge nodes; among which, transit nodes communicate with routing centers, edge nodes communicate with transit nodes and dispatch centers, audio and video cloud networks communicate with operator networks, and the network architecture of audio and video cloud networks Match the network architecture of the operator's network. By matching the audio and video cloud network with the operator's network, traffic detours are reduced and the service quality of the link is enhanced; by controlling the client's nearby access or preferential access to the edge node, the client's access to the audio and video cloud network is improved. At the same time, the routing and forwarding method is used to improve the transmission reliability within the audio and video cloud network, thereby improving the stability of audio and video communication and improving the user experience.

Description

technical field [0001] The present invention relates to the technical field of real-time audio and video communication, and in particular, to an audio and video system, an access method, a routing and forwarding method, and a readable storage medium. Background technique [0002] With the popularization of mobile Internet and the commercialization of 5G (5th-Generation Mobile Communication Technology), people's demand for low-latency, high-reliability audio and video applications is growing. Real-time audio and video communication (Real Time Communication, RTC) has become a hot technology field. In particular, the arrival of the global epidemic has accelerated the development of various industries such as RTC-based video conferencing, interactive live broadcast, and video surveillance. Today, RTC has evolved into a complex field including network transmission, streaming media processing, transmission protocols, codec algorithms and other related technologies. [0003] In t...

AI Technical Summary

Problems solved by technology

[0004] The user audio and video experience cannot reach the level of communication: audio and video data transmission links are lengthy, the network structure is complex, and the underlying network lacks quality assurance

For example: the transmission delay is large, the ability to resist weak networks is poor, and the player often has problems such as jitter and blurred screen

[0005] Low performance: The jump between network element nodes lacks intelligent scheduling and routing systems, and nodes have single-point bottlenecks, which cannot support large-scale traffic

For example: all data goes to the optimal link, causing the link to be saturated soon, while other links are idle

[0006] High cost: the transmission network of each business line is fragmented, and some functions are duplicated; and the coupling degree of each module structure is high, and the operation and maintenance workload is heavy

For example: conferences and live broadcast interactive audio and video networks are independent of each other, and the cost of repeated construction is high; and when an alarm occurs on a certain link, a lot of manual investigation is required, and new resources must be coordinated and allocated

[0007] With the deepening of technology research and development, the above phenomena and disadvantages have been implemented in actual projects, and finally evolved into: QoS (Quality of Service) guarantee of each layer of network, the initial (final) ) one-kilometer access, network internal link transmission and other technical problems, which lead to unstable audio and video communication and poor user experience
