Embodiment

[0035] See figure 1 , several physical devices RD form a VM (virtual machine). In the present invention, RD is regarded as a container providing network services, that is, it can install any network service program (RD APP) that meets the requirements, and on the other hand it is an output unit of network bandwidth, that is to say, RD can send The Internet provides bandwidth resources. RDs interact with clients for data, and agent modules are installed on these RDs. The role of the agent module is to monitor the status of RDs, mainly the uplink and downlink bandwidth status of RDs, obtain the operating load of RDs, and send instructions to RDs. On the top of the agent module, a virtualized API is set. The virtualized API is a bridge connecting the RD and the virtualized scheduling unit, and the optimal RD device is automatically selected to provide services to the client through the virtualized API. The upper UI interface communicates with the virtualization scheduling unit,...

Abstract

The invention discloses a CDN acceleration system realized by virtualization technology, comprising: a CDN server, a virtual server and a client, wherein the CDN server is used to send data to the virtual server; the virtual server distributes the received data to the client; Wherein, a physical device RD is set in the virtual server, and the physical device RD gathers the surplus uplink and downlink bandwidth. The present invention realizes network acceleration by using the excess bandwidth in the network system, adds a special device RD on the upper layer of the client to form a virtual network, utilizes the surplus bandwidth of the uplink and downlink, and provides network access through the application program loaded on the special device. Serve. The virtualized service layer of the present invention is combined with the traditional CDN-P2P network to replace the CDN layer and the client for data transmission, which can effectively reduce the bandwidth dependence of the live broadcast service on the CDN. Due to the flexibility of the architecture, different network services can also be provided by deploying different applications on the RD.

Description

technical field [0001] The present invention relates to a framework and a method for distributing real-time content such as audio and video, and in particular to a system and method for CDN dynamic acceleration. Background technique [0002] As the number of Internet users continues to increase, the user's requirements for audio and video live broadcast quality / sound quality continue to increase, the code stream of live content continues to increase, and the number of online users continues to increase. The requirements for bandwidth and concurrent online users are gradually restricting this business. the bottleneck. Calculated with a bit rate of 1Mbps, 1G bandwidth can only support 1000 concurrent users, but to ensure 1 million users are online at the same time, 1000G bandwidth is required, which is very expensive for a single live program. On the other hand, 1 million concurrent streaming access is also an impossible task for the performance of ordinary servers. Therefor...
