BitTorrent constructs an overlay network without considering the structure of the underlay network and the redundant traffic between ASes causes the increase in the peering cost. Although one of the ways to eliminate redundant traffic is to utilize in-network cache in programmable nodes, the challenge is to retain high cache hit ratio. This paper proposes three steps for resolving this issue: (1)infer the pieces of files to be exchanged in near future, (2)caching algorithm, and (3)SDN flow control to increase hit ratio, and especially reports the evaluation in (1). To be concrete, we think it effective to infer rare pieces perceived by peers transparently to peers, since BitTorrent adopts Rarest First Algorithm where rare pieces are to be exchanged first. Thus, inspecting BITFIELD/HAVE messages within network, we evaluate by simulation how effectively our proposed method infers the rare pieces that peers observe. |
