Henrik, I was talking with Chin about the following example and his understanding was different than mine. I think I have it wrong but wanted to check. For the link "urn:ogf:network:aruba:bonaire-otn" my understanding was from Bonaire I could use EVTS to reach Curacao with a cost of 2, and I could use OTN to reach Bonaire (back to me) with a cost of 1. Chin indicated that the type of service used on the link "urn:ogf:network:aruba:bonaire-otn" is not described as it is know between the two ends of the link (implicit), and what the entries indicate is you can reach Curacao with EVTS through Aruba at a cost of 2. So if the implicit service on link "urn:ogf:network:aruba:bonaire-otn" is OTN, then adaptation will occur somewhere to get you to the "EVTS" service in Curacao. So in Chin's explanation a single service type is on the link "urn:ogf:network:aruba:bonaire-otn" and the service adaptations are described. In mine the services on the link are described but adaptation is not. Could you please clarify? Thanks, John On 2015-02-05, at 9:59 AM, Henrik Thostrup Jensen <htj@nordu.net> wrote:
