Introduction
Service engineering, or more simply service engineering, is the discipline that addresses the technologies and engineering processes for the specification, implementation, testing, deployment, usage of end-user services in communication networks. Communications networks fall under two umbrellas: conventional networks and challenged (or non conventional) networks. Challenged networks are networks that violate one or more of the TCP/IP Internet design assumptions. An example of conventional network is the Third Generation Partnership Project (3GPP) 3G network that comes with the IP multimedia system (IMS). Another example of conventional network is the enterprise network. Mobile ad hoc networks (MANETs) and wireless sensor and actuator networks (WSANs) are examples of challenged network. They are either sessions-based (e.g. multimedia/multiparty games, distance learning) or non-session based (e.g. instant messages, video on demand). Engineering end-user services in communication networks is a big challenge. The widest possible range of services needs to be engineered; all the phases of the life cycle (e.g. development, deployment, execution, usage and withdrawal) need to be reckoned with; and the specifics of the communications networks need to be taken into account. Comprehensive architectures are required. End-user services are the raison d’ętre of communications networks. This gives a strategic importance to service engineering. However, there are still very few research laboratories in academia focusing on service engineering. The Telecommunications Service Engineering (TSE) Laboratory is among these few laboratories. It has been created in January 2003 as a joint laboratory between the Concordia Institute for Information Systems Engineering (CIISE) and the Electrical and Computer Engineering department (ECE). We deal with all aspects of service engineering in communication networks, including:
