We conducted a series of side-by-side live experiments, involving two clients running on the same machine downloading the same file at the same time. We found that the download latency varied significantly, sometimes by a factor of 2. Surprisingly, the main contributing factor isn't the network bandwidths of the set of neighbors that a client is given. Rather, it has to do with the frequency of turn-overs in \"close\" neighbors, i.e. those that are in a stable data-exchange relationship with the client. Analysis of the log data shows that a client obtains over 90% of the file from a small set of close neighbors, and if a close neighbor leaves the network, it takes the client a long time,\n            <jats:italic>over half an hour<\/jats:italic>\n            , to find another one. This suggests that self-organizing P2P file distributions indeed need external help in order to provide QoS guarantees, but such guarantees are achievable with proper enhancements to the P2P network.\n          <\/jats:p>","DOI":"10.1145\/1151374.1151382","type":"journal-article","created":{"date-parts":[[2006,10,18]],"date-time":"2006-10-18T22:35:32Z","timestamp":1161210932000},"page":"22-30","update-policy":"http:\/\/dx.doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Can self-organizing P2P file distribution provide QoS guarantees?"],"prefix":"10.1145","volume":"40","author":[{"given":"Ruchir","family":"Bindal","sequence":"first","affiliation":[{"name":"Stanford University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pei","family":"Cao","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2006,7]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Proceedings of SIGMETRICS, 2005","author":"Bharambe A.","year":"2005","unstructured":"A.
