Applicability of Proxy Mobile IPv 6 for Service

Applicability of Proxy Mobile IPv 6 for Service Provider Wi-Fi Deployments Byju Pularikkal Rajeev Koodli Sri Gundavelli

Motivation • PMIPv 6 is specified as a mobility protocol which is access agnostic. The specifications do not make any assumptions on the access technology. • There has been lot of momentum around the use of PMIPv 6 based Architecture models for SP Wi-Fi deployments • In addition to the requirements around mobility, various Wi-Fi specific deployment needs can be addressed by the PMIPv 6 protocol and the extensions • Objective is to go over the architecture use cases for SP Wi-Fi based up on PMIPv 6 and discuss some of the key deployment considerations

Scope of the document • Architecture Models o Flat Model Deployments with EPC Integration o Hierarchical deployments with domain chaining • WLAN Access Network Types o Controller based o Autonomous • Deployment Considerations o o o IP addressing Access authentication & user identity Realizing Point to Point link models on WLAN access Policy Provisioning Accounting Considerations SIPTO Considerations
