Janet Futures
The Janet network provides connectivity for research and education in the UK. It aims to deliver high bandwidth and availability to connect the UK research sector and infrastructure to global networks. Janet is designed for research and education purposes, not commercial or central government use. It has a hierarchical design with access connections to customer sites, regional infrastructure, and a national backbone with high-capacity external connections. Looking ahead, Janet plans to standardize equipment, rationalize its infrastructure, and increase use of fibre to reduce costs and complexity while improving availability, speeds, and flexibility.
