Abstract

The invention aims at providing a method and device for controlling data block transmission in a network based on a peer-to-peer protocol. The method is particularly applicable to the situation of user equipment DHT agency. A directory server receives address information sent by agent user equipment for requesting user equipment, and judges whether to allow the agent user equipment to acquire a data block or not according to the address information. By implementing the invention, regional control in a P2P network live broadcasting system can be well guaranteed, and live broadcasting signals can be effectively controlled to be transmitted only in a defined area.

Description

technical field [0001] The invention relates to a method and a device for controlling data transmission in a network based on a point-to-point protocol, in particular to a method and a device for controlling data transmission in the field of streaming video playing. Background technique [0002] With the increasing popularity of the Internet and the rapid development of new technologies, a large number of emerging network multimedia applications have emerged and become an important part of people's work and life. These multimedia applications in the Internet, especially the dissemination of multimedia information based on video often require the support of streaming media technology. Streaming media refers to the continuous audio and video data streams transmitted and played in chronological order on the data network, which has the characteristics of continuity, real-time and timing. Due to these characteristics of streaming media, it has become the main way to transmit aud...
