Routing-information-based server selection in widely distributed web servers

摘要

In a traditional simple server client model, many service requests overconcentrate to the server. Now, CDN (Content Delivery Network) is used to solve this problem. To construct a CDN, request-routing system is required. It navigates a user request to one of appropriate servers. In this paper, we present a new server selection mechanism. This system refers routing information, and is based on DNS servers. It is independent of servers and clients. We evaluate the system in a solar eclipse live web servers at 21 June, 2001. In this experiment, we navigated 80.9% of requests to one of their neighbor server.
