Developing and testing new GSM services requires use of proprietary hardware and software which can be tedious due to inherent high complexity and cost. The product GSM call service developed by nine master students at Uppsala University provides a vendor independent, low cost, IP based solution according to 3GPP specifications. The system designed and developed using Erlang/OTP is a framework capable of calls, subscriber management and additional GSM services. The finished product offers developers a testing environment to build and ex-

As more and more Web services are delivered in the form of Common Gateway Interfaces (CGI) scripts, the efficiency at which Web servers execute CGI scripts is becoming ever more important. In this paper we show that the performance overhead associated with invoking a conventional CGI script could

services are created and deployed rapidly. In the World Wide Web, the Common Gateway Interface (CGI) has served as popular means towards programming web services. Due to the similarities between the Session Initiation Protocol (SIP) and the Hyper Text Transfer Protocol (HTTP), CGI is a good candidate

Software which mediates is common today, but the structure, the interfaces, and implementations vary greatly, so that automation of integration is awkward. By formalizing and implementing mediation we establish a partitioned

This paper factors out the common denominator underlying these variants: full decoupling of the communicating entities in time, space, and synchronization. We use these three decoupling dimensions to better identify commonalities and divergences with traditional interaction paradigms. The many
