Problems solved by technology

Second, because the CDN lacks sufficient understanding of the network status information of the server provided by the ISP, there is still room for optimization in the content distribution and route distribution of the CDN.
[0023] Since TCP migration is required in this solution, and the TCP migration process needs to collect all information related to the connection state, this leads to high complexity of the system

Abstract

Embodiments of the invention disclose a method and a device for cooperative processing of data between a CDN (Content Delivery Network) and an ISP (Internet Service Provider), the ISP knows a cache server, which is selected to provide the service for a client by the CDN network, and the interaction complexity is low and implementation is simple. In the technical scheme of the invention, the ISP knows the cache server, which is selected to provide the service for the client by the CDN network, so that the ISP can master the actual flow of the network in real time to provide a better cooperation basis for cooperative processing of the data between the CDN and the ISP, and furthermore, the ISP network utilizes the SDN technology to carry out real-time congestion processing and flexible routing according to the actual flow of the network, the network is more flexibly monitored and managed, and the customer experience is improved.

Description

technical field [0001] The present invention relates to the field of mobile Internet, in particular to a method and device for co-processing data between a Content Delivery Network (CDN, Content Delivery Network) and an Internet Service Provider (ISP, Internet Service Provider). Background technique [0002] The rapid growth of network traffic dominated by video content has brought great challenges to existing networks. First of all, for operators, the rapid growth of network traffic makes the network very congested, and the response speed of user requests slows down. In order to improve network conditions, operators can only continuously expand network bandwidth. However, with the reduction of voice and short message business volume and the decline of traffic and traffic charges, the network expansion of operators has not brought considerable benefits to themselves. [0003] Network congestion and slow response to user requests also put enormous pressure on content provide...
