A global framework for architecture analysis in telecommunications

One currently observes a multiplication of actors and technologies involved in the provisioning of telecommunications services. To represent them and their relationships, to understand the stakes, many models have been designed, each one with its own application zone: business models, network management and architectures, etc. At the same time, the road towards next generation networks (NGN) needs to be carefully mastered. NGN are expected to support all kind of services, to provide generalized mobility with QoS guarantee and to be open with standardized interfaces and protocols. So one needs tools to deal consistently with this context complexity. This paper addresses a global framework for telecommunications architecture analysis, able to deal with the complexity of the domain. The framework is then illustrated by two applications: the first one presents a global QoS framework and the second one deals with the IP QoS issue.
