That leads me to wonder whether the IETF will be chartering multiple WGs to standardize EAP encapsulation over IP. Although my understanding of both PANA and NEA is no doubt incomplete/wrong/confusled, having multiple EAP encapsulation standards seems duplicative to me. > As for 3GPP2, I can get into really gory details of what has been happening > there, but it's not technical at all (if you are familiar with 3GPP2 and the > relevant players in this discussion, you can guess). The issue is that integration of PANA with link layer technologies requires the support of the organizations that own those link layers. Without that link layer integration (for whatever reason) the scenarios can't be realized, at least in a mainstream way. It seems to me that one of the motivations for PANA is to *avoid* link layer dependencies in situations where link layer technology is inadequate/can't be deployed, and a forklift upgrade isn't in the budget. In those circumstances, integration with link layers or IPsec VPN technology is not under consideration -- because that would require a forklift upgrade. For example, the wireless hotspot case where something more sophisticated than a Web portal is needed, but a forklift upgrade to WPA2 or a VPN deployment isn't a realistic alternative. Or the shared wired media case where "network port authentication" doesn't really work, and wholesale switch port replacements aren't affordable. In both of those cases, EAP over IP might provide a light weight, easily deployed solution. Yet, rather than focusing on the specific scenarios in which PANA might be compelling, the PANA framework document tries to cover a wide range of potential uses, trying to position PANA for use in scenarios where the case is less obvious. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
