Anthony Chan, Huawei Technologies Charlie Perkins, Tellabs Telemaco Meria, Alcatel-Lucent Bell Labs Hui Deng, China Mobile Wassim Haddad, Ericsson IETF79 MEXT WG1

2 Background and motivation Mobile data is literally growing exponentially Smartphones generate much more traffic than plain old mobile phones Mobile operators are starting to offload mobile traffic to WiFi networks and deploy local Content Delivery Network Standardization for mobile data offload is underway in other SDOs 3GPP LIPA/SIPTO This issue is not only for one SDO, but for the whole Internet Renovate the conventional mobile network More distributed and scalable model IETF79 MEXT WG2

3 Where to distribute…? IETF79 MEXT WG APAP HA/LMAHA/LMA AR/FA/MAGAR/FA/MAG 3 MHMH Core-level AR-level Access-level Mobile Core Network Access Network Host-level

4 Core-level distribution Keep existing hierarchy Traffic and mobility bindings are distributed over HA/LMAs Handover, signaling and/or routing may be needed between HAs/LMAs IETF79 MEXT WG4 APAP HA/LMAHA/LMA AR/FA/MAGAR/FA/MAG MHMH Core-level AR-level HA/LMAHA/LMAHA/LMAHA/LMA AR/FA/MAGAR/FA/MAGAR/FA/MAGAR/FA/MAG APAPAPAP MHMH InternetInternet

5 AR-level distribution Role of HA/LMA is regressed Traffic and mobility bindings are distributed over ARs Signaling and routing needed between ARs IETF79 MEXT WG5 APAP AR/FA/MAGAR/FA/MAG MHMH AR-level HA/LMAHA/LMA AR/FA/MAGAR/FA/MAG AR/FA/MAGAR/FA/MAG APAPAPAP MHMH InternetInternet

6 Access-level distribution Role of mobile core is regressed Part of AR functionality is combined with AP Access Node (AN) =AP+AR Distribute traffic and mobility bindings over ANs Signaling and routing needed between ANs IETF79 MEXT WG6 FA/MAGFA/MAG MHMH Access-level HA/LMAHA/LMA MHMH InternetInternet ANANANANANAN

7 Access NW Mobile Core Host-level distribution Peer-to-peer communication between MHs More independent of the mobile network Signaling and routing needed between MHs IETF79 MEXT WG7 MHMH Host-level MHMH InternetInternet

8 How to distribute…? Possible approaches for Distributed Mobility Management Partially distributed approach Fully distributed approach IETF79 MEXT WG8

9 Partially distributed approach (I) Control and data plane separation Control plane: Centralized Data plane: Distributed IETF79 MEXT WG MAMA MAMA MAMA MAMA MAMA Control Function 9 MA: Mobility Anchor Registration Route Setup MH1MH1 MH2MH2

10 Partially distributed approach (II) Dynamic mobility management Mobility is provided on demand IETF79 MEXT WG10 AR1AR1 MH1MH1 CH1CH1 CH2CH2 AR2AR2 MH1MH1 IP1 IP2 IP1 MHMH MHMH MHnMHn MHMH MHMH CHnCHn MH1 mobility binding MH1 mobility binding

11 Fully distributed approach Both control and data planes are distributed IETF79 MEXT WG11 MAMA MAMA MAMA MAMA MAMA MA: Mobility Anchor (including control function) MH1MH1 MH2MH2 Dynamic mobility management also applies Selection of the appropriate mobility anchor is an issue

12 Mobility anchor selection in fully distributed approach Ex.1: broadcast/multicast approach No routing is needed Good for regional area, probably not for global IETF79 MEXT WG MAMA MAMA MAMA MAMA MAMA 12 MH1MH1 MH2MH2

13 Mobility anchor selection in fully distributed approach (contd) Ex.2: Search & delivery Efficient look-up mechanisms exist, but still takes time to discover the corresponding MA scalability issue could remain IETF79 MEXT WG MAMA MAMA MAMA MAMA MAMA 13 MH1MH1 MH2MH2

14 Analysis and proposal More flat architecture is preferred for effective distribution Flexible and manageable routing is needed for selective traffic offload AR/Access-level distribution Scalability must be considered Partially distributed approach is likely to be more practical so far IETF79 MEXT WG14
