Motivation

Service Providers are deploying Wi-Fi Services over residential architectures. They are exploring protocol options for build a new service model

that can meet all the service requirements.

Document ScopeIdentify

requirements

for deploying SP WI-Fi Services

IPv6 addressing is a key to the new service modelsome of the requirements for the service may be not IPv6 specific but may have an impact. This document should Identify protocols that can be used to support these architectures. Provide analysis for the different approaches

The goal is not define protocol extensionsbut may identify the gaps in existing tools, which can be the basis for new protocol workSlide6

ConclusionsThis proposal got

good

reviews

. There is lot of interest for this work.There are signficant amount of investments in Service Provide WiFI deployments. This work is highly relevant for ensuring those deployments leverage the existing IETF tools and make the right design choices.Authors request the draft be adopted as the WG document.
