6NET was a three-year IPv6 deployment project that featured 11 European National Research and Education Networks (NRENs). Led by Cisco, who contributed at least 16 high-end GSR routers, and including IBM, 6NET had a total project budget of over 15M Euros and 1,100 man months of resources. The project was a key precursor to the full production IPv6 services in European academic networks including GEANT. ECS' main role in the project was leadership of the IPv6 transition and integration work package, which considered interworking between IPv4 and IPv6 systems. The project was extended due to its success, and scored maximum ratings in its final assessment.
