Exploring PMIPv6 Applications in Service Provider Wi-Fi Deployments

This paper discusses the applicability of Proxy Mobile IPv6 (PMIPv6) for service provider (SP) Wi-Fi deployments. PMIPv6 architecture is agnostic to access technologies, making it suitable for various deployment models. We cover architecture use cases, including flat and hierarchical models, deployment considerations like IP addressing and user identity, and factors such as policy provisioning and accounting. By examining the requirements and benefits of PMIPv6, we identify how it can address the specific needs of Wi-Fi networks, enhancing mobility and service performance.

  1. Applicability of Proxy Mobile IPv6 for Service Provider Wi-Fi DeploymentsByju PularikkalRajeev KoodliSri Gundavelli

  2. Motivation • PMIPv6 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 PMIPv6 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 PMIPv6 protocol and the extensions • Objective is to go over the architecture use cases for SP Wi-Fi based up on PMIPv6 and discuss some of the key deployment considerations

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