Work Package 1 (WP1) provided the network requirements and analysis to form the foundation of the subsequent work packages in the ETNA project. The work undertaken in WP1 is described within the final deliverable document which is available here.

Ethernet has established itself as the technology of choice in the local area network (LAN). The recent addition of carrier class features is allowing Ethernet to extend beyond the LAN into metro and core transport networks which were traditionally dominated by circuit-switching technologies.

The broad vision of the ETNA project addresses the requirements for a future transport network based on carrier-class Ethernet technologies. WP1 has defined the overall vision based on the anticipated user requirements, the new service possibilities and the evolution of transport network technologies which are increasingly Ethernet-centric.

We have taken particular care to reflect operator demand based on projected customer bandwidth requirements over the next decade. This demand, in conjunction techno-economic trends in the marketplace will shape the ETNA architecture.

In WP1 we have addressed the high-level business drivers, the current mix of transport technologies deployed by European operators and the future service and bandwidth trends. Using this as a point of departure the ETNA project can now focus its efforts to define an architecture which addresses challenges in key areas such as inter-carrier/inter-domain services, mobility, scalability and network control.

A key output of WP1 is a network model that divides the network functionality into three distinct layers: the transport layer, the transport services layer and the value-added services layer.

The network requirements are rooted in real services and customer demand. We have produced a comprehensive “demand matrix” which captures the key attributes and requirements. These are referenced to a suite of typical services that address the real needs of wholesale, business and residential customers. Related service requirements have been assigned to “orthogonal” categories covering capacity, provisioning, delay, robustness, as well as management and operational issues

The WP1 deliverable contains tables covering the specific service requirements within each category. When combined these tables form the “demand matrix” that acts as a key point of reference for the transport network requirements to guide the subsequent work packages.

The output of WP1 will feed into the ETNA architecture (Work Package 2) and ultimately into the demonstrator (Work Package 7) which will be built in the later stages of the project.
