FLAIR: Flexible Access networks using Intelligent and Reconfigurable elements
A collaboration between Bangor University and BT
The bandwidth need of end users increases by more than 50% each year.
Some experts are predicting subscriber demand for >1Gb/s network services by 2018. Such rates are challenging for existing copper-based access networks without shortening the copper loop to <50m or so. Furthermore, internet traffic tends to be highly dynamic nearer to the network edge because of unpredictable user behaviour. Such a dynamic traffic pattern requires new approaches to avoid network over-provisioning and inefficient utilisation of network resources. Passive optical networks (PONs) are widely deployed and provide a cost-effective and “future-proof” fibre infrastructure to enable end-users to enjoy >1Gb/s.
This project will contribute to a dynamic, application-aware, software-controlled, high throughput network framework capable of automatically and elastically extending required facilities depending upon actual application demand.
The project will:
- theoretically and experimentally explore innovative technical solutions capable of delivering DSP-enabled intelligence and software-controlled flexibility/reconfigurability, and
- extensively investigate the feasibility of introducing advanced solutions into future high-speed Passive Optical Networks) for practical implementation in intelligent, elastic and reconfigurable optical access networks.
