  1. SP Wi-Fi Services over Residential Architectures(draft-gundavelli-v6ops-community-wifi-svcs) IETF 83, March 2012 Authors: Sri Gundavelli(Cisco) Mark Grayson (Cisco) Yiu Lee (Comcast) Pierrick Seite (FT - Orange) Hui Deng (China Mobile)

  2. Motivation • Service Providers are deploying Wi-Fi Services over residential architectures. They are exploring protocol options for build a new service modelthat can meet all the service requirements. Wi-FI Service Cloud Public SSID Residential Access Point Residential Access Point Provider Access Point Private SSID Private SSID

  3. Document Scope • Identifyrequirements for deploying SP WI-Fi Services • IPv6 addressing is a keyto the new service model • some of the requirements for the service maybe 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 extensions • but may identify the gaps in existing tools, which can be the basis for new protocol work

  4. SP Wi-Fi Service for Retail Model Operator-1 CPE Internet IP Tunnel CPE Access Aggregation Gateway WLC S2a (PMIPv6 or GTP) CAPWAP Operator-2 Layer-2 CAPWAP CPE Subscriber Service Control IP Tunnel Operator-3 CPE SP Wi-Fi Network Mobile Packet Core (Partner Networks)

  5. Key Service Requirements • CPE Identity and Authorization • Subscriber Authentication • 802.1x/EAP Authentication • Web-based Authentication • Transparent Auto Login • Location based Services • Local Services Access • Integration with Mobile Network • Multiple Home Network Service Access • Overlapping IPv4 Address Support • Mobile Network Integration • IP Mobility • Roaming within the WLAN Access Network • Roaming across Cellular and WLAN Access Network • Selective IP Traffic Offload • Service Differentiation • SSID to which the user is attached • Home User vs., Visitor • Rate Limiting & QoS Control • IPv6 Accounting • Lawful Interception • Charging Function • Service Provisioning and Monitoring

  6. Conclusions • What is expected from IETF? • Recommendations of the protocols that can be used to support this new service model • Identify IPv6 specific gaps in each of those models • Analysis of each of the option and how it addresses different requirements
