Efficient Content Distribution and Storage P2P System based on Information Dispersal

Recent advances in communication networks and the computing capabilities of computers have opened up new opportunities for content storage and distribution, where cloud storage and media distribution over the Internet have gained significant popularity. However, most computer systems may have failures on both the software and hardware side. Furthermore, as the Internet has grown, traditional server based system have introduced new problems such as bandwidth bottlenecks, limited performance and dependability. In this paper, we propose a fault-tolerant collaborative architecture for storing and distributing multimedia files based on the information dispersal algorithm (IDA). Our proposed architecture is based on the P2P paradigm in such a way that the nodes can take both the server and client roles at the same time. In this way, a file can be allocated efficiently to many peers by using the information dispersal algorithm, and only a subset of these peers are required to rebuild the original file.
