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.
