10-Gigabit-capable Passive Optical Network (XG-PON), one of the latest standards of optical access networks, is regarded as one of the key technologies for future Internet access networks. In this paper, we propose and discuss the design and implementation of an XG-PON module for the NS-3 network simulator. The aim is to provide a standards-compliant,(More)
—Content Distribution currently accounts for the vast majority of Internet traffic. Peer-to-Peer represents a scalable and inexpensive strategy to deliver content to end-customers; unfortunately, it poses a sever strain on the network core and generates high costs for service providers. Locality-aware policies have been proposed to tackle these issues, but(More)
We report on an emerging application focused on the design of resilient long reach passive optical networks using combi-natorial optimisation techniques. The objective of the application is to determine the optimal position and capacity of a set of metro nodes. We specifically consider dual parented networks whereby each customer must be associated with two(More)
—Current DSL products that provide broadband over copper pair are reaching their capacity limits. In many cases, their peak rate struggle to deliver HDTV video streams, which are widely acknowledged as one of the killer Internet applications in the near future. Fibre to the premises (FTTP) solutions are being deployed to address the problem of scarce(More)
—We present an application focused on the design of resilient long-reach passive optical networks. We specifically consider dual parented networks whereby each customer must be connected to two metro sites via a local exchange sites. An important property of such a placement is resilience to single metro node failure. The objective of the application is to(More)
