Obiettivo
The main objective of the ATMOSPHERIC project is to identify network configurations and solutions which will accommodate the uncertain service growth and mix during a network transition towards full ATM based IBC. Verification and evaluation of recommended solutions will be supported through the construction of a model to assess technology performance requirements, the flexibility / compatibility of network architectural concepts and design options, and the economic viability of ATMOSPHERIC's solutions for upgrading the local distribution network to provide IBC.
The main objective of the ATMOSPHERIC project is to identify network configurations and solutions which will accommodate the uncertain service growth and mix during a network transition towards full asynchronous transfer mode (ATM) based integrated broadband technology (IBC). Verification and evaluation of recommended solutions will be supported through the construction of a model to assess technology performance requirements, the flexibility/compatibility of network architectural concepts and design options, and the economic viability of ATMOSPHERIC's solutions for upgrading the local distribution network to provide IBC.
Market predictions for the transition phase leading to a mature broadband network have been issued. For the network, novel features and concepts have been promoted, including: the flexible architecture and building-block (BB) concept, definitions of a set of reusable generic key elements (GKE) and key components (KC), completion of designs of demonstrator versions of these building blocks and the extended stratified reference model (ERM), which proposes a new way of using the lower three layers of the open system interconnection (OSI) reference model.
A demonstrator configuration has been defined from selected network capabilities and services, required during the transitional period.
ATMOSPHERIC has contributed to standardisation and common functional specification (CFS). It has constructed building blocks using appropriate technologies and high technology components, application specific integrated circuits (ASIC).
Technical Approach
The principal areas of study within the project are network functionality, network configuration, and technology. The first two aspects are derived from service and network evolution considerations. Techniques for network resource allocation and management have been studied as inputs to building block specification.
Implementation technology has been evaluated in three stages: Identification of the key technologies available in the late 1990s; selection of currently available technologies for demonstrator implementation; and identification of key industry-standard components for use in IBC networks.
Key Issues
- Interworking with existing public networks and supporting access from existing terminals and subscriber premises networks.
- Development of a flexible and economic network and system architecture allowing reuse of existing network resources.
- Validation in a demonstrator of the proposed solutions and recommendations.

ATMOSPHERIC has contributed to the work of all three Parts of RACE I, ie: contributions to standardisation and CFS; it has constructed building blocks using appropriate technologies and high-tech components (ASICs); and contributed to the BIPED and BUNI demonstrators.
Expected Impact
ATMOSPHERIC is uniquely positioned to provide inputs to actors within the telecoms sector, on the 'hybrid solutions' required during a network transition towards full ATM operation. These inputs cover the relevance of new transmission standards and switching techniques, and how these may interwork within hybrid networks. ATMOSPHERIC can explain the means by which existing terminals and services may continue to be supported, and the benefits provided by an open architecture.
