  1. DMM Framework based on Functional Elementsdraft-liebsch-dmm-framework-analysis-02 M. Liebsch, P. Seite, G. Karagiannis IETF88, Vancouver DMM WG08th November 2013

  2. Preamble.. • DMM can be enabled by deployment • Mobility protocols and components • Other components, e.g. Transport Network • Interworking between these components • Proven technology is available in operators’ TN • IP, IP-MPLS, SDN technology • Objectives • Provisioning of technology to enable operators with tools to deploy DMM in their network • Consider extensions of existing protocol functions • Consider provisioning of hooks and definition of attributes to enable inter-working • Increase gain in deploying DMM • Increased networking performance (data path) • Lower costs (transport, encapsulation, data path)

  3. Methodology • A protocol-agnostic Functional Framework supports building DMM solutions around existing mobility protocols • Enables various deployment models (self contained mobility protocols or by system integration) • Used to build missing capabilities (gaps) to accomplish DMM • Distributed mobility context management and transfer between distributed anchors • Traffic steering after runtime anchor change • Advanced traffic steering by mobility state exposure and inter-working with transport network (Forwarding Control, Forwarding Elements)

  4. Methodology • This framework document defines 4 Functional Elements (FE) to close identified gaps (mobility control and data path management) • Supports the specification of required protocol gaps • Document defines clear reference points between FEs • Supports the specification of hooks/attributes to enable optimal deployment Forwarding Element(Ingress) Rules for traffic steering DMM_I Traffic Steering andForwarding Control Ctrl Expose Mobility States(e.g. Routing Locator) Forwarding Element(Egress) DMM_E Mobility ContextManagement and Transfer CTX

  5. One abstract deployment model Data Mobility Context Management and Transfer CTX Expose Mobility States (e.g. Routing Locator) Ctrl Traffic Steering and Forwarding Control Rules for trafficsteering New Mobility Anchor Previous Mobility Anchor DMM_E DMM_I DMM_E DMM_I Note:For detailed deploymentmodels with MIPv6, PMIPv6, please refer to the draft Mobile Node

  6. Another abstract deployment model Data CTX Expose Mobility States(e.g. Routing Locator) Rules for traffic steering Ctrl DMM_I New Mobility Anchor Previous Mobility Anchor DMM_E DMM_E Note:For detailed deploymentmodels with MIPv6, PMIPv6, please refer to the draft Mobile Node

  7. Summary ..What’sNext? • DMM analysis and specification of extensions should be done on a functional level • Proposed functional framework enables the specification of protocol gaps and hooks for optimal deployment • WG indicated large interest in working on a frameworkat IETF87 • Framework considered mature • Receivedcommentswill go intonextrevision • Publishwithreasonable effort and lowlatency • Considered as suitable documentation to support nextstepsin the DMM WG
