Back-Office traffic on the Internet
Most often when people think about the Web or the Internet they only consider the interactions between the browser and the front-end server. Indeed, although traffic between Web servers and Web browsers is readily apparent to many knowledgeable end users, fewer are aware of the extent of server-to-server Web traffic carried over the public Internet. We refer to the former class of traffic as front-office Internet Web traffic and the latter as back-office Internet Web traffic (or just front-office and back-office traffic, for short).
Back-office traffic, which may or may not be triggered by end-user activity, is essential for today’s Web as it supports a number of popular but complex Web services including large-scale content delivery, social networking, indexing, searching, advertising, and proxy services. This talk takes a first look at back-office traffic, measuring it from various vantage points, including from within ISPs, IXPs, and CDNs. We then discuss implications and opportunities that the presence of back-office traffic presents for the Internet ecosystem.
