ABSTRACT This article presents an open and functional architecture based on a next-generation network solution in order to seize its converged nature to guarantee interoperability among different platforms and terminals. The defined architecture is an integrated solution for end-to-end communication of various IP multimedia subsystem platforms marketed by different vendors, belonging to several operators located in different countries across Europe and supporting multiple terminals and technologies in order to experiment with a new broadband telephony service for the residential environment. This work addresses, in particular, the interoperability problems of name resolution and implementation of the session initiation protocol interface at the terminal as a key use in such a scenario. Also, several advanced services are developed and tested within the proposed architecture as a proof of concept of the IMS capability for quick service creation and deployment. The architecture proposed contributes to the reduction of obstacles and barriers among the European countries in order to adopt NGN architectures, allowing a new type of communication that is more complete and flexible.

    ABSTRACT: In this paper we have introduced a new concept of network management scheme aimed at maximizing the telco profit. Besides the competition among telcos, it is introduced between users as well. Telcos compete through quality of service and price. Users compete in reservation of resources, i.e. services and QoS in the specified time period and between particular sites. This concept should be supported by two different traffic policies, which we call E-policy and L-policy. E-policy is based on static (fixed), while L-policy on dynamic (statistical), MUX techniques. Major components of the system are: legal acts defined by legal authorities, telco rules for network management and control, the network under control and the traffic observer. Legal act is a public document which ensures transparency to end users. The results of simulation, obtained through extensive testing, prove the correctness of proposed method for optimizing telco profit and show that, neither pure E nor pure L policy, can give the maximum profit. This stems from the fact that both prioritize, albeit differently, the type of traffic, whereas in order to maximize the profit telco should schedule the routers to prioritize traffic by the price offered–to–bandwidth and QoS required ratio Our mixing procedure, keeping the current router schemes, and thus not requiring any new investments in equipment, makes the step in this direction, and immediately shows a possible 40% increase in telco profit due to this simple combination.

    ABSTRACT: Rationale for this paper is our opinion that in the future collaboration between ICT and humanistic sciences, today quite disjoint, it will be necessary to overcome technical details of networks (OSI seven layers) and define applications that are far beyond seventh layer. To achieve this goal we propose object oriented graphical language UML as a common language for specifying humanoid (human like thinking) applications in the future.
