All, Attached is the following document: Inter-Domain Controller (IDC) Protocol Specification We would like to submit this document to the NSI Working Group to consider for publication as a NSI WG Informational Document. This is being submitted on behalf of the DICE Control Plane Working Group, where the IDC Protocol (IDCP) was developed. DICE is a collaboration amongst DANTE (GEANT), Internet2, CANARIE, ESnet, USLHCnet, and others. This protocol has been implemented and is currently deployed by ESnet, Internet2, GEANT AutoBAHN, USLHCnet, and others. The objective of this submission is to provide another example of a currently deployed protocol in this area, in case it is helpful to the ongoing NSI standardization efforts. Another objective of this submission is that we would like to have the IDCP specification formally documented as an informational release in this OGF working group.
