چکیده
The recent move towards market deregulation and open competition has sparked a wave of serious introspection in the telecommunications service industry. Telecom providers and operators are now required to open up their primary revenue channels to competing industries. In this paper, we examine the service structure of two major global communication networks the Telephone Network and the Internet and explore their weaknesses and strengths. Building upon the experience we gained during the development of the initial xbind prototypes, we discuss the realization of an open programable networking environment based on a new service architecture for advanced telecommunication services. Our approach to the problem stems from two angles one conceptual, the other implementational. In the first, we attempt to develop a service model that is open and reflects the economic market structure of the future telecommunications service industry. We believe that investigating such a model will help clarify some of the pertinent issues confronting the telecommunications service industry today as it comes of age. An engineering model for realizing the service market model is proposed as a vehicle for creating multimedia services on broadband networks. In the second, we investigate the feasibility of engineering this model from an implementation standpoint. We address some of the important issues fully aware that our work has opened new vistas that call for additional research. We believe that our work will lead to a major shift of paradigm in research and development of service architectures for telecommunication networks. It has already found strong resonance with the members of the OPENSIG international working group and its foundations have been proposed for possible standardization by Nortel.

Stochastic Optimization Problems in Telecommunications
We survey different optimization problems under uncertainty which arise in telecommunications. Three levels of decisions are distinguished: design of structural elements of telecommunication networks, top level design of telecommunication networks and design of optimal policies of telecommunication enterprize. Examples of typical problems from each level show that the stochastic programming par...

HLP (hub location problem) tries to find locations of hub facilities and assignment of nodes to extended facilities. Hubs are facilities to collect, arrange, and distribute commodities in telecommunication networks, cargo delivery systems, etc. Hubs are very crucial and their inaccessibility impresses on network whole levels. In this paper, first, total reliability of the network is defined bas...
