    摘要： Embodiments of the present invention provide a cache method, a cache edge server and a cache core server, where the cache method includes: receiving, from the cache core server by using a channel, information about a Transmission Control Protocol flow; determining, according to the information, whether the cache edge server stores content corresponding to the information; sending a migrate-out request to the cache core server based on that the cache edge server stores the content corresponding to the information; receiving a migrate-out response from the cache core server upon the sending of the migrate-out request; performing a Transmission Control Protocol connection to user equipment according to the migrate-out response; and reading content corresponding to the connection from storage of the cache edge server according to a byte quantity, sent by the cache core server, of the content, and sending the content to the user equipment. In this way, the network cache system in the embodiments of the present invention can still implement an existing function in a case of no cache token server. In addition, because a cache token server is omitted, a download speed is further improved and costs for deploying the cache token server are further reduced.

    摘要： Embodiments of the present invention provide a network system and a network communication method. The network system includes: a third-party server and an edge node that are located in a radio access network or an IP transport network between the radio access network and a wireless core network, where the edge node steers a TCP packet that is of user equipment for a central server and that corresponds to a TCP connection to the third-party server, and the third-party server includes an application server or a cache server, and is configured to store delivery data of the central server and respond to the TCP packet according to the delivery data. In the embodiments of the present invention, a cache server or an application server is moved from an IDC equipment room in a metropolitan area network to a local radio access network or an IP transport network between the radio access network and a wireless core network, and an edge node is deployed to steer a TCP packet for a central server to the cache server or the application server, to implement traffic scheduling. In this way, a transmission delay from the radio access network to a packet core network is reduced, thereby improving user experience.
