In this paper, we propose Mutualcast, a new delivery mechanism
for content distribution in peer-to-peer (P2P) networks.
Compared with prior one-to-many content distribution approaches,
Mutualcast achieves full utilization of the upload bandwidths
of the peer nodes, thereby maximizing the delivery
throughput. Mutualcast splits the to-be-distributed content into
many small blocks, so that the more resourceful nodes may redistribute
more blocks, and the less resourceful nodes may redistribute
fewer blocks. Each content block is assigned to a single node
for distribution, which can be a content-requesting peer node, a
non-content-requesting peer node, or even the source node. The
throughput of the distribution is controlled by redistribution
queues between the source and the peer nodes. Furthermore, Mutualcast
can be reliable and synchronous. Thus, it can be applied
to file/software downloading, media streaming, real-time audio/
video conferencing, etc.
