P2P流媒体直播中一种AS友好的节点选择算法的性能改进

Performance Improvement of an AS-friendly Peer Selection Algorithm for P2P Live Streaming

Yukinobu Fukushima, Kazuki Kobayashi, Tokumi Yokohira

摘要:

最小物理跳数(MPH)是一种用于减少P2P流媒体直播中自治系统(AS)间流量的节点选择算法。在MPH中,新加入的对等体选择其物理跳数(即,在内容传递路径上经过的AS的数量)作为其提供对等体是最小的。然而,MPH显示高AS间的流量时,加入对等体的数量是大的。在本文中,我们提出了IMPH,试图通过分配具有一个逻辑跳数的对等体(即,在从OSS到对等体的内容传递路径上经过的对等体或源流服务器(OSS)的数量)到许多AS,并鼓励后面的对等体在同一AS内找到它们的提供对等体。数值例子表明,IMPH实现在最大的64%,降低AS间的流量比MPH。

英文摘要:

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 peer whose physical hop count (i.e., the number of ASes traversed on the content delivery path) from it is the minimum as its providing peer. However, MPH shows high inter-AS traffic volume when the number of joining peers is large. In this paper, we propose IMPH that tries to further decrease the inter-AS traffic volume by distributing peers with one logical hop count (i.e., the number of peers or origin streaming servers (OSSes) traversed on the content delivery path from an OSS to the peer) to many ASes and encouraging the following peers to find their providing peers within the same AS. Numerical examples show that IMPH achieves at the maximum of 64% lower inter-AS traffic volume than MPH.
