A method for establishing a terminal connection, a terminal and a server

Abstract

The invention provides a method enabling a terminal to establish connections, a terminal and a server. The objective of the invention is to solve the problem of incapability to realize communication between a second terminal and a first terminal when the second terminal is in a local area network or the second terminal and the first terminal are located in different local area networkers in the prior art. The method includes the following steps that: the first terminal generates a connection request containing identification information of the second terminal and sends the connection request to the server, and the server is made to transmit the connection request to the second terminal according to the identification information of the second terminal; the first terminal receives a connection request reply message which is generated by the second terminal and contains the candidate addresses of the second terminal and is forwarded by the server, wherein the candidate addresses of the second terminal include the upnp address of the second terminal and port speculation addresses of the second terminal which are distributed in disorder; and the first terminal carries out communication detection according to the candidate addresses of the second terminal, and establishes a connection with the second terminal when communication detection is successful.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a method for establishing a terminal connection, a terminal and a server. Background technique [0002] Media streaming refers to a multimedia application in which video, sound and other data are carried by the real-time transport protocol and transmitted from the source to the destination in the form of a continuous stream, and can be played after receiving certain cached data at the destination. With the wide application of video-on-demand, the traditional media streaming transmission system has exposed many problems. The impact of user-on-demand on the server is too large, which is easy to cause a single point of failure, so the introduction of peer-to-peer (Peer to Peer, P2P) transmission The so-called P2P technology refers to the direct transmission of data between network users, and each node for data transmission is equal. At present, the application of P2P techno...
