Hybrid equivalent and master-slave type data transmission architecture and method

Abstract

The invention discloses a hybrid equivalent and master-slave type data transmission architecture and a hybrid equivalent and master-slave type data transmission method, wherein an original source end determining the data transmission mode of linked points is an equivalent mode or a master-slave mode, and then a plurality of linked points are divided into an equivalent group and a master-slave type group. Besides, the original source end dynamically determines the quantity of individual members in the equivalent group and the master-slave type group and the regulated and allocated upload bandwidth, so that a balance point on efficiency can be obtained between transmission time delay, limit of upload bandwidth of the data source end, network capacity and system load during data transmission.

Description

technical field

[0001] The present disclosure relates to a hybrid (Peer-To-Peer, P2P) and client-server (client-server) data transmission system and method. Background technique

[0002] For an Internet service, such as multimedia streaming (streaming), file download (filedownload), etc., the size of the network bandwidth is equivalent to the packet delay time (delay time) that affects the quality of service (Quality-of-Service, QoS) important parameter. Adopting a client-server data transmission architecture can reduce unnecessary transmission time delay (propagation delay), but a large upload bandwidth is required on the server side. The larger the upload bandwidth leased, the higher the operating costs. The P2P data transmission architecture does not require a large upload bandwidth on the server side, but it will cause a long transmission time delay. For time-sensitive applications, the delay will make it impossible to watch real-time audio and video data. For file d...
