TYPE A PROJECTS
PROJECTS IN THIS CATEGORY PLANNED TO BE STARTED IN 1984/85 ARE DESCRIBED BELOW . IN COMMUNICATION SYSTEMS ARCHITECTURE , SUPPORT OF MORE THAN ONE PROJECT IS CONSIDERED WHEN DIFFERENT ASPECTS NEED TO BE EMPHASIZED .
4.3.1 . COMMUNICATION SYSTEM ARCHITECTURE
DESCRIPTION
DETERMINE THE TOPOLOGIES MOST APPROPRIATE FOR TYPICAL OFFICE SITUATIONS INCLUDING LOCAL , DISTRIBUTED AND LONG-HAUL LINKED OFFICES , GIVEN BY TRAFFIC REQUIREMENTS AND DISTANCE . DEFINE NETWORK MANAGEMENT STRATEGY INCLUDING APPROPRIATE NETWORK ACCESS PROTOCOLS AND MULTIPLEXING SCHEMES , EXPLORING THE POSSIBILITIES OF NETWORK ERROR RECOVERY , RECONFIGURATION AND OVERALL CONTROL . THE ARCHITECTURE SHOULD PROVIDE FOR GATEWAY FUNCTIONS TO TAKE ACCOUNT OF FUTURE DEVELOPMENTS IN THE PUBLIC NETWORK AND ALSO FOR PRIVACY AND SECURITY REQUIREMENTS .
THE INDUSTRIAL INTEREST FOR THE DEVELOPMENT OF STANDARDS AND THE EXECUTION OF CONFORMANCE TESTS IS PART OF THE PROJECT DEFINITION .
PROGRAMME
YEAR 1 :
- STUDY ALTERNATIVES OF ARCHITECTURES , WITH PARTICULAR RESPECT TO DISTRIBUTED WORKING , TECHNOLOGIES TO BE EXPECTED , TRAFFIC CHARACTERISTICS , REQUIREMENTS FOR MONITORING AND LOGGING , NETWORK MANAGEMENT AND CONTROL , AND FOR SECURITY OF ACCESS AND DATA TRANSFER .
YEARS 2 TO 5 :
- DESIGN BASIC ARCHITECTURES ( E . G . LAN-BASED , PBX-BASED ) ON THE KNOWLEDGE ACQUIRED ABOVE ;
- FIRST STATEMENTS ON ECONOMICS , PERFORMANCE , STANDARDS ;
- DEFINITION OF COMMUNICATION SERVER AND OTHER GATEWAY FUNCTIONS , INCLUDING FUNCTIONS WHICH CONVERT THE DIFFERENT TYPES OF PROTOCOLS INTO A COMMON LAN PROTOCOL FOR INTRA-OFFICE NETWORKING , INTER-OFFICE OPEN SYSTEM INTERCONNECTION , DATA-BASE ACCESS AND REMOTE INFORMATION CENTRES ;
- REFINEMENT OF ARCHITECTURE ( E . G . ROUTING ) ; STANDARDIZATION ACTIVITIES ; PREPARATION OF EXPERIMENTAL IMPLEMENTATION AS FAR AS APPEARS NECESSARY ( E . G . PILOT COMMUNICATION SERVER ) ;
- STANDARDIZATION ACTIVITIES ; REALIZATION OF EXPERIMENTAL IMPLEMENTATION ;
- EVALUATE ARCHITECTURE BY RESULTS OF EXPERIMENTAL WORK .
YEAR 3 :
- WORK ON TOOLS TO BE STARTED IN YEAR 3 :
- IDENTIFICATION OF TOOLS REQUIRED . IDENTIFICATION OF RELEVANT STANDARD COMMUNICATION INTERCHANGE AND MANAGEMENT PROTOCOLS ( SESSION , TRANSPORT AND NETWORK ) . IDENTIFICATION OF RELEVANT EQUIPMENT ARCHITECTURES . DEFINITION OF TOOL ARCHITECTURE ,
- SPECIFICATION OF INDIVIDUAL TOOLS . DESIGN AND CONSTRUCT TOOLS .

4.3.2 OPTICAL WIDEBAND LAN
DESCRIPTION
IDENTIFY AND FORMULATE ARCHITECTURES AND STANDARDS FOR OPTICAL WIDEBAND LOCAL AREA NETWORKS , DEFINE THE DESIGN REQUIREMENTS OF VLSI CHIPS AND DEMONSTRATE THE FUNCTIONAL
