TLDR
Clusters---a grouping of clients that are close together topologically and likely to be under common administrative control are introduced, using a ``network-aware" method, based on information available from BGP routing table snapshots.Abstract:
Being able to identify the groups of clients that are responsible for a significant portion of a Web site's requests can be helpful to both the Web site and the clients. In a Web application, it is beneficial to move content closer to groups of clients that are responsible for large subsets of requests to an origin server. We introduce clusters---a grouping of clients that are close together topologically and likely to be under common administrative control. We identify clusters using a ``network-aware" method, based on information available from BGP routing table snapshots.read more

Community detection in graphs
TL;DR: A thorough exposition of community structure, or clustering, is attempted, from the definition of the main elements of the problem, to the presentation of most methods developed, with a special focus on techniques designed by statistical physicists.

Distributing streaming media content using cooperative networking
TL;DR: This work considers the problem that arises when the server is overwhelmed by the volume of requests from its clients, and proposes Cooperative Networking (CoopNet), where clients cooperate to distribute content, thereby alleviating the load on the server.

On the placement of Web server replicas
TL;DR: This work develops several placement algorithms that use workload information, such as client latency and request rates, to make informed placement decisions, and evaluates the placement algorithms using both synthetic and real network topologies, as well as Web server traces.

Topologically-aware overlay construction and server selection
TL;DR: In this paper, the authors present a binning scheme whereby nodes partition themselves into bins such that nodes that fall within a given bin are relatively close to one another in terms of network latency.

Flash crowds and denial of service attacks: characterization and implications for CDNs and web sites
TL;DR: An enhancement to CDNs is proposed that offers better protection to Web sites against flash events and trace-driven simulations are used to study the effect of the enhancement on CDNs and Web sites.

Web caching and Zipf-like distributions: evidence and implications
TL;DR: This paper investigates the page request distribution seen by Web proxy caches using traces from a variety of sources and considers a simple model where the Web accesses are independent and the reference probability of the documents follows a Zipf-like distribution, suggesting that the various observed properties of hit-ratios and temporal locality are indeed inherent to Web accesse observed by proxies.
