Network system and network communication method

Abstract

The embodiment of the invention provides a network system and a network communication method. The system comprises a third party server of an IP transmission network located at a wireless access network or between the wireless access network and a wireless core network, and a border node, wherein the border node guides a TCP message corresponding to the TCP connection aiming at a center sever by the equipment to the third party server; the third party server comprises an application server or a cache server for storing the distributing data of the center server and responding to the TCP message according to the distributing data. Through the adoption of the system provided by the embodiment of the invention, the cache server or the application server is sunk to the IP transmission network located at the local wireless access network or between the wireless access network and the wireless core network, and the border node is deployed to guide the TCP message aiming at the center server to the cache server or the application server to realize the flow dispatching. Therefore, the transmission delay to a grouping core network from the wireless access network is reduced, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a network system and a network communication method. Background technique [0002] A content delivery network (Content Delivery Network, CDN) is a content delivery and traffic distribution network that is built on a basic network protocol (Internet Protocol, IP) bearer network and is oriented to various business needs. The purpose of CDN is to publish the application content of the website to the network "edge" closest to the user's device by adding a new layer of network architecture to the existing Internet (Internet), so that the user's device can obtain the required content nearby. It does not need to be obtained from the application server, which can solve the congestion of the Internet network and improve the response speed of the user's equipment when accessing the website. [0003] The content distribution network can distribute the content...

Problems solved by technology

However, in the existing CDN solution, the service nodes are generally deployed in the Internet Data Center (IDC) computer room of the metropolitan area network. Therefore, the time delay for mobile network users to access the service nodes is long and the user experience is poor.
