[Essnet] ESS inter-site network description

All, the description and offer has now been narrowed down to a description of the inter-site connectivity, on the assumption that ESS requires (and will be getting) upstream connectivity to DeIC and SUNET anyway. Please read and comment; I will send the document to ESS this week. /Lars -- Lars Fischer - Strategy & Policy, NORDUnet <lars(a)nordu.net>, +45 2288 1729, @lpfischer
