Locality Analysis of Today's Internet Web Services   

Joachim Charzinski (Nokia Siemens Networks)

In the beginning of the Web, one Web page was equal to one HTML file that was
retrieved from one server and contained links to other pages which might reside
on other servers. Today, Web pages contain many elements that are collected from
different servers. With the advent of Web APIs, even mashups are designed that
retrieve and combine data from a number of remote servers on the Internet. This
paper investigates the locality structure of modern Internet Web services by
analyzing the number of hosts, routing domains and external services contacted
by a Web client that uses some of today's most popular Web sites. Those results
are compared to the characteristics shown by selected mashup sites.
