Active and passive optical networks are compared. Based on a reference model that covers AON and PON as well as the interfacing equipment, the different sites and locations in an access network are identified. Such a reference model is necessary in order to make a proper techno-economical comparison between the various optical access network architectures.… (More)
We propose a fibre access network paradigm achieving low latency, high throughput and energy efficiency, by combining the best of PON and AON, optical and electrical forwarding, and the concepts of software defined networks, flexible grid, and cache assisted networking.
Next-generation optical access networks will deliver substantial benefits to consumers including a dedicated high-QoS access to bit rates of hundreds of Megabits per second. They must also deliver significant benefits to network owners/operators to justify the needed infrastructure investment expected to reach billions of Euros. Benefits to network… (More)
This paper focuses on the problem of coherent resource allocation within home and access networks. The interdomain QoS signaling discussed here enables the initiation of the QoS provisioning in the home and access from the end device in users home. The home network considered in this paper is UPnP-QoS enabled while the access network is GMPLS based. We… (More)
Distribution of media data over the Internet is increasing in popularity and volume. This poses challenges not only for network operators but also for service providers when it comes to serving the demand in a cost-efficient way. In this paper, we approach this problem by investigating the potential of co-operative approaches where locality in space (users… (More)
