The MPLS network inter-connecting member institutions is riding on a 10Gbps transmission capacity leased from two private telecommunications operators; Airtel Nigeria and Phase 3 Telecoms. NgREN also maintains access links to these institutions and owns and manages all core and edge network devices. The topology of the first phase of the network has four cores anchored at collocation sites in Abuja, Kano, Lagos, and Portharcourt. The 29 members currently connected have last-mile links terminating at these locations. Subsequent phases of the network will feature an expansion in the number of these core sites to 14.
