On Network-Aware Clustering of Web Clients

The paper "On network-aware clustering of web clients" presented at SIGCOMM ’00 by Krishnamurthy and Wang proposes clustering techniques to move content closer to the clients which are generating most of the traffic.

Before the paper, cluster of clients were simply /24 networks. The authors propose to group clients by BGP prefixes.

The paper is focused on web traffic and to determine the quality of the BGP clustering, the authors analyses web server logs. Based on the logs, they map client IP addresses to BGP prefixes.

The paper "An Overview of Routing Optimization for Internet Traffic Engineering" presented by Wang et al. in IEEE Communications Surveys volume 10, N°1 presents a complete survey of the current techniques for traffic engineering.

In this blog, we will not summary the survey, just present the structure.

The paper divides TE according to four criteria.

1. scope: interdomain vs intradomain
2. enforcement: MPLS-based vs IP-based
3. timescale: online vs offline
4. type: unicast vs multicast
