Ping triangulation: A process developed by IBM in which client requests over the Internet can be routed to the cell that is geographically closest. When one or more mirror sites exist, ping triangulation uses a process called echo-location. When a server receives a client request, it sends out an ICMP echo, or ping, packet across the Internet to the mirror sites and times the echo response. From this information, the most appropriate site to respond to the client request is determined.

XSP: Short for eXtensible Server Pages. The XSP language is a core technology of Cocoon, XML-based Web publishing in Java and one of the seven parts of the Apache XML Project. XSP is used to build dynamic XML content. It was originally created to allow Web authors to generate dynamic content without forcing them to learn a programming language. Because a Web document’s content, style and logic are often created by different working groups or individuals, Cocoon aims for a complete separation of the three layers. Using XSP, content, style and logic are separated into different XML files using an XML DTD and are merged using XSL transformation capabilities.
