Personal Communication Space in Layered Networks

Objective

- To specify, design, implement and integrate a PSCS Service Node and a Terminal Extension unit into the TRIBUNE demonstrator for demonstration of PSCS key capabilities.
- To prepare and execute experiments, simulations, demonstrations, measurements and evaluations
- To base the implementation of PSCS services on the results of certain important RACE projects
- To define and apply an on-line Service Creation Environment for service implementation support
- To define a PERCOM PCS Service Node reference model based on ODP viewpoints.
- To study the behaviour of the TRIBUNE demonstrator running PSCS services and gain practical experience in the field of PSCS service elements implementation
- To contribute to UPT/PSCS standardisation
Personal communication space (PCS) in layered networks has been studied with particular emphasis to specify, design, implement and integrate a personal services communication space (PSCS) service node and a terminal extension unit into the TRIBUNE demonstrator for demonstration of PSCS key capabilities. The conceptual basis, including network and node architecture definitions, service and service element identification and definition, functional specifications and protocol considerations, is derived from RACE II projects - and other activities such as TINA-C. Close links are also established to TRIBUNE regarding the test bed for implementation work. This basic work has resulted in a specification for a service node, selected service elements and initial demonstration scenarios. The specifications, together with investigation results from the TRIBUNE test bed, lead to an implementation of selected service elements in a PCS prototype service node using the TRIBUNE network. A distributed PSCS architecture was designed adopting the open distributed processing (ODP) paradigm and object oriented techniques. The protocol between the PSCS service node and the PSCS terminals, has been specified. The project activities, although limited in extent, are fully scaleable to much larger network environments.
Technical Approach

The conceptual basis, including network and node architecture definitions, service and service element identification and definition, functional specifications and protocol considerations, is derived from RACE II projects - (mainly MOBILISE, CASSIOPEIA and SCORE) and other activities such as TINA-C. Close links are also established to TRIBUNE regarding the test bed for implementation work.

This basic work results in a specification for a Service Node, selected service elements and initial demonstration scenarios. The specifications, together with investigation results from the TRIBUNE test bed, leads to an implementation of selected service elements in a PCS Prototype Service Node using the TRIBUNE network. A distributed PSCS architecture is being designed adopting the ODP paradigm and object oriented techniques.

After the installation a comprehensive evaluation, experimentation and test programme will start in order to demonstrate certain PCS capabilities and to offer a platform for further experiments and simulations. All these experimentation activities are expected to deliver feed-back information for improving future conceptual work.

The project activities, although limited in extent, are intended to be fully scaleable to much larger network environments.

The work is being accompanied by planning-supportive and co-ordination activities and will conclude with contributions to standard bodies as well as to CFS and the RACE project lines.

Key Issues

- Demonstration of selected PCS key capabilities.
- Implemented PCS service node based on the TRIBUNE demonstrator including PSCS Terminals.
- Reference model for a PCS prototype service node.
- Operating functions for an implemented service node.
- Service creation support.
- Demonstrator (TRIBUNE Control Server) adaptation.

Expected Impact

The project bridges the gap between conceptual work and practical realisation and so allows exchange of experience and measurement results within RACE. PERCOM results will also facilitate and support the introduction of PCS for future applications.
