Abstract
Real-time streaming media system based on P2P technology includes the following two aspects of research:the first is the transmission scheduling strategy of data blocks,that is media content is divided into the same size of pieces,and how to requests the data block;the second is the construction of work,this process is known as members of the
managemem,that is constructed work is closer to the work topology,
the more it can improve the overall transmission performance,Because the work topology matching、析m the underlying data transfer path call reduce data transmission dalay
and cross-ISP paper studies these two issues,the main contributions are as
1:Data scheduling algorithm is point to a laser how to obtain the required sequence of data blocks,and from which node to obtain the data data scheduling algorithm is prior to access less data blocks,SO that the share properties of fresh data would be ignored
for a long fresh data sent from the server、^,itll the larger ID and these fresh data
is on the location of the buffer,this data has enough time to stay in the buffer and it can be
requested by another on these,this paper presents gragh coloring based data scheduling algorithm GCB(Graph color-based algorithm),in this algorithm,the obtaining data nodes not only follow the principle of uniform distribution but also take the duration of the sharing sliding window into acco瑚毒sharing data in the sliding window for a longer time
will enjoy a certain priority strategy is more effective especially when sbandwidth
resources are scare and number of connections is limited.
2:Taking into account the mesh-work is effective against node dynamic,but the structures do not take into account the problem of proximity between nodes,thus increasing the amount of interact traffic and transmission pared to the mesh-work,
tree-work considers the proximity problems work,thus this structure produces l
