| 10 : | camrdale | 78 | I began work on a Master's in Computing Science (thesis option) at Simon Fraser University in |
| 11 : | September of 2006. This is a change from my [[undergraduate work|Undergrad]], in which my major | ||
| 12 : | was in Physics, though I did minor in Computing Science. | ||
| 13 : | camrdale | 17 | |
| 14 : | camrdale | 78 | I chose Networking as the main area for my research, and further decided to focus on |
| 15 : | peer-to-peer networking. This has led me to choose Dr. Jiangchuan Liu as my supervisor, as he has | ||
| 16 : | contributed a lot of reasearch in this area, including the introduction of | ||
| 17 : | [CoolStreaming](http://en.wikipedia.org/wiki/CoolStreaming). | ||
| 18 : | camrdale | 17 | |
| 19 : | camrdale | 78 | My work is partially funded by an |
| 20 : | [NSERC Canada Graduate Scholarship M](http://www.nserc.ca/sf_e.asp?nav=sfnav&lbi=2a), | ||
| 21 : | which I was awarded in March of 2007. | ||
| 22 : | camrdale | 17 | |
| 23 : | camrdale | 78 | #### Research |
| 24 : | camrdale | 17 | |
| 25 : | camrdale | 140 | My current research is focussed mainly on [BitTorrent](http://en.wikipedia.org/wiki/Bittorrent). |
| 26 : | camrdale | 78 | One aspect I have studied is the effectiveness of the |
| 27 : | [*rarest-first* policy](http://wiki.theory.org/Availability) to evenly distribute | ||
| 28 : | pieces of the download throughout the peers. I have found that the policy is mostly effective at | ||
| 29 : | maintaining a near-optimal piece population distribution, though there are some areas for | ||
| 30 : | improvement. | ||
| 31 : | |||
| 32 : | camrdale | 140 | I have also examined the different network topologies formed between peers in a BitTorrent swarm. |
| 33 : | camrdale | 78 | Some of the networks I have found to have |
| 34 : | camrdale | 141 | [scale-free behaviour](http://en.wikipedia.org/wiki/Scale-free_network), verifying the resilience of the swarm to the failures and |
| 35 : | departures that are common in all peer-to-peer networking scenarios. Others that were previously thought to have | ||
| 36 : | [small-world characteristics](http://en.wikipedia.org/wiki/Small-world_network), I have found to contain very little | ||
| 37 : | camrdale | 142 | clustering. I have therefore designed an enhancement to the BitTorrent tracker to introduce clustering |
| 38 : | camrdale | 141 | and create a small-world from the BitTorrent swarm, which should improve the |
| 39 : | effectiveness of the BitTorrent protocol at | ||
| 40 : | distributing the download to peers. | ||
| 41 : | camrdale | 78 | |
| 42 : | camrdale | 141 | Using this work as a foundation, I am currently working on a new peer-to-peer download system for |
| 43 : | distributors of free content (mostly software packages) over the web. | ||
| 44 : | The system uses a Distributed Hash Table to support | ||
| 45 : | downloading the individual content files from peers, which reduces the strain | ||
| 46 : | on the network of mirrors that is usually required to support the downloads. | ||
| 47 : | This work includes implementing a new download client for software packages of | ||
| 48 : | Debian-based systems called [[apt-p2p]]. | ||
| 49 : | camrdale | 135 | |
| 50 : | camrdale | 78 | To simulate and measure BitTorrent swarms, I have been able to use the |
| 51 : | camrdale | 142 | [PlanetLab](http://www.planet-lab.org/) network, a global co-operative research network in over |
| 52 : | camrdale | 78 | 300 locations around the world that supports the development of new network services. For more |
| 53 : | information on this research, see my [[PlanetLab]] page. | ||
| 54 : | |||
| 55 : | In collaboration with another student, [Xu Cheng](http://www.cs.sfu.ca/~xuc/personal/), we have | ||
| 56 : | studied the video sharing site [YouTube](http://www.youtube.com). This new type of video | ||
| 57 : | distribution has not seen much research yet, and we find some interesting differences between it | ||
| 58 : | and traditional video distribution. My work focussed mostly on the social networking aspect of | ||
| 59 : | camrdale | 141 | YouTube, which is unique among video sharing sites. The results showed that YouTube videos form a |
| 60 : | camrdale | 78 | [small-world network](http://en.wikipedia.org/wiki/Small-world_network), which suggests that |
| 61 : | camrdale | 140 | videos are strongly correlated with each other. This feature can be used to develop interesting caching |
| 62 : | or peer-to-peer distribution strategies for videos. | ||
