Problems solved by technology
If the connection between the network block and the data source network block is disconnected, malfunctions, or the transmission efficiency is low, it will inevitably affect the data usage effect of all other users in the network block
[0007] Therefore, this currently popular algorithm has the following shortcomings in some parts on the large-scale Internet: first, low reliability; second, low stability; third, poor invulnerability; fourth, low transmission efficiency

Embodiment Construction
[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Such as Figure 1 to Figure 4 shown.
[0049]A method for maintaining high connectivity with data sources based on a global cache, including a pre-configured data live broadcast peer-to-peer network, and the technical measures taken include: at least the following operations:
[0050] Step 1: Each peer in the data live peer-to-peer network maintains two peer advertisement caches, one of which is a local cache, which stores peer advertisements exchanged with its neighbors; the other is Global cache, which stores advertisements of super peers that can maintain high-speed connections with data sources in the entire system;
[0051] Step 2: Each peer establishes network connections with several peers in the local cache, and the peers that have been established will become its neighbors;
[0052] Step 3: Each peer randomly exchanges the cached pee...

Each peer entity in peer-to-peer network of data living broadcast maintains local and global buffers. Connection is built between each peer entity and some peer entity in local buffer. Information list of peer entity in local buffer can be exchanged at random. Using peer entity data source, the invention filters out super peer entity possible to be connected by data source, and to keep connection in high speed. Through mode of peer-to-peer broadcasting, the method transfers information of super peer entity to each user peer entity effectively. Through keeping up multipoint connection with super peer entity, user peer entity keeps high connectivity with network blocks of data source. Advantages are: (1) keeping balanced load of data source as well as keeping connection to network blocks of data source in high speed; (2) capable of passing through boundary of network blocks by multiple points so as to raise data transmission efficiently; (3) raised stability and survivability etc.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method for maintaining high connectivity with a data source based on a global cache. It is applied in the data broadcast peer-to-peer network. Background technique [0002] In order to solve the problem of large-scale on-site users receiving data in real time, with the development of computer network technology, especially peer-to-peer network (P2P Network) technology and streaming media technology, the emerging network data live broadcast system based on P2P network structure has been developed rapidly. The P2P network data live broadcast system makes full use of the limited resources of the network, solves the scalability problem of the live broadcast system well, and is very suitable for large-scale video live broadcast applications. [0003] At present, the transmission network structure of the large-scale P2P data live broadcast system mostly adopts the P2P Overlay Netw...
