Aggregation Network Design Methodologies for Triple Play Services

Triple-play services and P2P IPTV have not only led to an increasing demand for bandwidth in broadband access networks, but also to the need for new service delivery architectures. The choice of an appropriate architectural approach and sizing model for the aggregation network is studied in this paper through cost optimization models, which encompass aspects of non-stop delivery, service flexibility, policy management and cost allocation. We propose two independent quantitative programming models that identify the cost of each architecture and the corresponding effect of each of the hardware constraints and traffic flows. We show that due to the next generation applications, the ISPs will need to re-engineer the broadband access infrastructure to accommodate intelligent aggregation and optimize for QoS-sensitive services.
