Problems solved by technology

[0007] However, because the P2P network system divides the data to be downloaded into small fragments, and downloads the small fragments in random order from each connectable node, it is difficult to realize real-time playback of data, and has to Wait until the entire data download is complete before starting to watch
For larger data, the waiting process will be very long

Embodiment Construction

[0036] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] see figure 1 , figure 1 It is a schematic diagram of partitioning and sharding data. As shown in the figure, the data to be downloaded is divided into several larger blocks, such as block 1, block 2, block 3, block 4, etc.; each larger block is divided into many small blocks Sharding, such as dividing block 1 into slice 1.1, slice 1.2, slice 1.3, slice 1.4, slice 1.5, slice 1.6, and so on. Wherein, the block is the smallest unit in the implementation of the playing system, and the blocks are downloaded in sequence; the segments are downloaded in random order (that is, there is no set order).

[0038] The workflow of the method of the present invention is introduced below.

[0039] see figure 2 , figure 2 It is a flo...

Abstract

The invention discloses a method for downloading data based on P2P technology, comprising the following steps: dividing the data to be downloaded into a plurality of blocks; sequentially downloading the blocks; dividing the blocks into a plurality of fragments during downloading the blocks; and downloading the fragments randomly. The invention maintains the advantages of P2P systems, greatly reduces the loads of servers, increases the downloading speed and overcomes the defect that the P2P systems can not play files in real time.

Description

technical field [0001] The invention relates to a data transmission and download method based on P2P technology, in particular to a data transmission and download method based on P2P technology of "local disorder, global order". Background technique [0002] In the past, the network video system used the C / S or B / S structure, that is, there was a server (Server) as an intermediate node, which processed the request of each node (Client or Browser) and sent data to the node. This process can only adopt the form of sequential downloading and sequential playing, and download and play the blocks sequentially according to the established order. [0003] The hardware defect of this structure is that the requirements for the source node are too high. Since the server often cannot meet the data capacity and transmission bandwidth required by the entire system, resulting in hardware bottlenecks, these systems often fail to meet the requirements of real-time playback. . In terms of s...
