Embodiment Construction

[0018] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The network architecture disclosed by the present invention is as figure 1 As shown, CNE (Content Network Endpoint, content network device or software) is deployed on the user side, and CNA (Content Network Array, content network array device) is deployed at the data center and Internet backbone of each ISP (Internet Service Provider, application provider). or software). The process link and process process of content network transmission are as follows: figure 2 As shown, the process processing frame covers the deployment of the management plane of the content network delivery, the coordination method of the control plane, and the design of the data plane. Through CN (Content Network, content network) control plane technology, a point-to-multipoint CNC (Content Network Chain, content network chain) chain is formed between CNE and CNA. The...

Abstract

The invention discloses an architecture for transmitting content through a network, and belongs to the technical field of communication networks. The architecture comprises a CNE deployed at the userside and CNA devices or software deployed at all ISP data centers and internet backbones, point-to-multipoint CNC links are formed between the CNE and the CAN devices or the software, and the CNE monitors the quality of the CNC links through real-time lines between the CNE and the CNA devices or the software, and dynamically updates a CNT table arranged in the CNE according to a line quality monitoring result. An overlay network constituted by the CNE and the CNA devices or the software transmits business requests of the user side and content data accessed by an ISP operator, and data transmitting with high real-time performance, large capacity and high availability is achieved.

Description

technical field [0001] The invention discloses a framework for realizing content network transmission, which belongs to the technical field of communication network. Background technique [0002] The basic idea of ​​Content Delivery Network (CDN) is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. By setting up CDN node servers at the edge of the network, the CDN system can redirect the user's request to the service closest to the user based on comprehensive information such as network traffic, connection of each node, load status, distance to the user, and response time in real time. On the node, its purpose is to enable users to obtain the required content nearby, alleviate the congestion of the Internet network, and improve the response speed of users visiting websites. [0003] The existing CDN is based on the business model of B2C (...
