Power Line communications (PLC) provides “Broadband Ethernet” connectivity directly to the customer’s socket in home without additional cabling. However, PLC networks do not provide global end-to-end connectivity and need to rely on incumbent’s telecom networks. In order to lower the cost of CAPEX and OPEX the network interconnection is done at “Ethernet” level. Most of Incumbent’s networks are based on SONET/SDH Rings, and efficient transport of Ethernet over those technologies is a prime requirement. Ethernet over SDH/SONET (EoS), enables internet services over existing SONET/SDH systems using a simple structure. However, SONET/SDH is a TDM technology optimized for voice, and the standard rates are bandwidth inefficient when data is transported. With virtual concatenation it is possible to provide fine granularity in the transport of data traffic over SONET/SDH. The combination of these two technologies (EoS and virtual concatenation) in the same system will allow remote LANs to be connected together at lower costs in a very simple and bandwidth efficient way.

This paper describes the Broadband For All Cluster, which resides within the IST (Information Society Technologies) Thematic Area of the EU’s 6 Framework Programme. By explaining the topics being addressed by the projects in the Cluster, it gives a summary of the current trends in broadband provision in the access and core networks, from the perspective of the major industrial and network operations organisations throughout Europe. Since there will be further Calls for projects in this Strategic Objective, it can be a useful guide towards assessing where important topics have been overlooked.

Convergence is a key concept in development of a broadband infrastructure. The concept of broadband for all is often linked with the idea of one ubiquitous broadband network But the point of departure for ensuring broadband access for all is however quite different. The existing communication infrastructure is made up by a number of networks, with different architectures and serving different communication needs. This paper discusses the implications and challenges of convergence, which have to be addressed if the vision of broadband for all is to be realised.

The standardization work has been successfully achieved under the leadership of CableLabs, with the successful launch of DOCSIS 1.0 and 1.1 products, and the finalization of the DOCSIS 2.0 [1] specification. Definition of an interoperable Voice over IP architecture covering signaling, provisioning, security has been achieved [2], allowing MSO to deploy data and voice access systems on an economical way.

An important problem of broadband Internet infrastructures is efficient resource utilisation at access points, while keeping the Quality of Service (QoS) demands of applications stable and optimal. Considering the resource bottleneck of broadband access networks, there is a need for integrated performance management of such networks providing “feedback” from monitoring and analysis of traffic, QoS parameters, topology and anomaly effects for the purpose of short and long term bandwidth resource planning. This paper is aimed to discus design challenges of advanced performance management architecture for efficient bandwidth resource planning of broadband access networks with monitoring “feedback”. Based on resource planning and performance data base, the proposed architecture is designed to include techniques and algorithms for modelling and simulation of optimal resource allocation strategies in advance considering impact of traffic, topology selection, and anomaly analysis as well as feedback from QoS analysis. Application specific QoS monitoring and analysis is used for validation of resource allocation planning considering QoS based applications, such as VoIP, multimedia and Grid. The architecture is derived from the experiences of INTERMON project for inter-domain QoS analysis studying the impact of topology and traffic (see [1], [2], [4]). A scenario for the integration of QoS and topology analysis of INTERMON toolkit in the proposed performance management architecture is described.
