Problems solved by technology

However, there are also some problems in the tree structure network. For example, compared to other network topologies (grid, ring, star, etc.), the Peer nodes in the tree structure network The dependence of the CDN server in the network will be relatively large, which will not be conducive to the future development of the CDN-P2P fusion network. Peer nodes whose nodes are farther away have poorer performance, which will also affect the overall performance and scalability of the CDN-P2P fusion network, which is not conducive to the growth of network layers

Embodiment Construction

[0053] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0054] In order to combine the flexibility and expansibility of the grid structure and the manageability and controllability of the tree structure, the present invention proposes a brand new CDN-P2P fusion network topology—tree CDN-P2P fusion based on the grid structure network architecture.

[0055] The invention is a network structure design scheme applied in the CDN-P2P fusion network networking scheme. Specifically, the present invention is a brand-new network framework that combines the existing tree-type CDN-P2P fusion network framework and grid-type CDN-P2P fusion network framework, hoping to provide CDN service providers and users with a The CDN-P2P converged network architecture that takes advantage of CDN and P2P ensures the robustness of the CDN-P2P converged network while guaranteeing the service quality of the network.

Abstract

The invention provides a tree CDN-P2P fusion network framework based on a grid structure and a method thereof, and belongs to the field of content delivery networks and the field of P2P (Peer to Peer) networks. The tree CDN-P2P fusion network framework based on the grid structure comprises a CDN server and Peer nodes on each layer, wherein the grid structure is formed between the Peer nodes on the upper layer and the Peer nodes on the lower layer under the precondition that a tree network topology is integrally maintained; the CDN server can provide the service capability of Nc, namely the concurrent connections of Nc strips; each Peer node needs k connections for service, and the k connections are respectively connected to k different Peer nodes to form the grid structure.

Description

technical field [0001] The invention belongs to the field of content distribution network (Content Delivery Network) and peer-to-peer network P2P (Peer to Peer) field, and specifically relates to a tree-type CDN-P2P fusion network framework and method based on grid structure. Background technique [0002] While the transformation and development of network technology has brought great progress to society, it has also made people no longer satisfied with obtaining static content and text information on the network. The popularity of multimedia content (Multi-media Content) has promoted the continuous development and transformation of network technology to meet people's needs to a certain extent. At present, among the more popular network technologies, there are two technologies that are very suitable for the distribution and distribution of multimedia content. Delivery, they are content distribution network CDN (Content Delivery Network) and peer-to-peer network P2P (Peer to ...
