Dear All, I object to the decision of removing the FQDN option, because this option is crucial for supporting load balance and redundancy in our deployment scenario. If needed, I'm available to work with the authors in order to clarify both the use case and the language in the draft in order to address the points raised by the IESG.

As I mentioned in previous e-mails, the FQDN name option is needed for some scenarios such as load balancing. Having DHCP server acting as a load balancer is not an option for us. If the problem is only with the language as mentioned by D. Hankins, then the spec should be clear enough. I hope the wg will re-consider this position and defines the name aftr option. Cheers, Med -----Message d'origine----- De : softwires-boun...@ietf.org [mailto:softwires-boun...@ietf.org] De la part de Alain Durand Envoyé : mardi 12 octobre 2010 21:01 À : Softwires list Cc : Ralph Droms Objet : [Softwires] DHCP option for DS-lite Dear wg: draft-ietf-softwire-ds-lite-tunnel-option<mailto:draft-ietf-softwire-ds-lite-tunnel-opt...@tools.ietf.org> has been reviewed by the IESG with input from the dhc wg. Their conclusion was that having both an IP option and an FQDN option to describe the tunnel-end-point was redundant. After many discussion between the IESG and the authors, the authors decided to remove the FQDN option, leaving only the IP address option in place. The rationale is that the B4 element should remain as simple as possible and presenting multiple tunnel-end point alternative would seriously complicate the implementation on the client side. For example, the client would have to keep track which end-point is currently the best alternative and we would have to develop a complex mechanism to do that. Load balancing is better achieve by the DHCP server sending the proper tunnel end-point to the B4 element. There are cases where more complex B4 elements could benefits from having multiple tunnel endpoint to choose from, but those are not expected to be the common case and they should be dealt with differently. Our AD, Ralph Droms, asked us to verify there is consensus in the wg to do this. > David, Alain - The authors made a significant change to > draft-ietf-softwire-ds-lite-tunnel-option, deleting the FQDN option based on > IESG review and input from the dhc WG.
