Problems solved by technology

However, the controllability of the P2P network topology is poor, and the flow of data is disorderly. At the same time, each client node can join and exit the network at any time, which brings many challenges to the stability of the system.
When some of the network users in the P2P group suddenly withdraw from the P2P group, there may be faults in the network streaming media resources in the P2P group, which will affect the download process of the streaming media resources of the users.
Among them, the P2P network topology is built based on the C / S architecture. However, it is not so commonly used in the browser system B / S architecture where streaming media transmission is more frequent.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0026] The present invention provides a kind of method of streaming media multi-level cache technology, the method is:

[0027] 1. With the advantages of CDN network acceleration service, build a CDN streaming media network structure belonging to the present invention, and distribute streaming media resources to resource servers and edge node cache servers.

[0028] 2. Since this system runs on a WebRTC-based browser, according to the real-time communication characteristics of WebRTC web pages, WebRTC technology supports point-to-point connections of clients. So when the client connects, the signaling server is introduced. It enables the clients in the group to be connected to each other, and realizes the client P2P network structure in the group.

[0029] 3. Since mul...

Abstract

The invention discloses a streaming media multi-level cache network acceleration system based on WebRTC. The system comprises a CDN network structure and an intra-group client P2P (Peer to Peer) network group structure. The intra-group client P2P network group structure obtains cache resources from edge cache nodes of the CDN network structure. The intra-group client P2P network group structure comprises a client in support of WebRTC, and a signaling server. The client in support of WebRTC applies a browser cache technique. The system is equipped with a center data source multi-point data cache structure, and the service capability reliability of the system is improved.

Description

technical field [0001] The invention relates to the field of network acceleration, in particular to a streaming media multi-level cache network acceleration system and method based on WebRTC. Background technique [0002] The P2P (Peer to Peer) technology is introduced into the CDN system, and the transmission mode between the content server and the user in each edge autonomous domain adopts the P2P mode. However, the controllability of the P2P network topology is poor, and the flow of data is disorderly. At the same time, each client node can join and exit the network at any time, which brings many challenges to the stability of the system. When some network users in the P2P group suddenly quit the P2P group, there may be a fault in the network streaming media resources in the P2P group, which affects the downloading process of the streaming media resources of the users. Among them, the P2P network topology is built based on the C / S architecture, but it is not so commonly ...
