摘要：Minimum Physical Hop (MPH) has been proposed as a peer selection algorithm for decreasing inter-AS(Autonomous System) traffic volume in P2P live streaming. In MPH, a newly joining peer selects a peerwhose physical hop count (i.e., the number of ASes traversed on the content delivery path) from it is theminimum as its providing peer. However, MPH shows high inter-AS traffic volume when the number ofjoining peers is large. In this paper, we propose IMPH that tries to further decrease the inter-AS trafficvolume by distributing peers with one logical hop count (i.e., the number of peers or origin streamingservers (OSSes) traversed on the content delivery path from an OSS to the peer) to many ASes andencouraging the following peers to find their providing peers within the same AS. Numerical examplesshow that IMPH achieves at the maximum of 64% lower inter-AS traffic volume than MPH.
