Mobile CORD

A more detailed outline of the M-CORD Roadmap is available here (7.4MB powerpoint).

...

  • RAN Slicing – Policy-based resource isolation

    • vBBU assigns and manages radio resource blocks to different slices under the control of an ONOS slicing app
    • Slicing app talks to RAN agent (vBBU) through proposed OF-extensions
    • Slicing app acts on UE-based, time-based, location-based, and services-based policies
    • Service classification is implemented by UE and/or BBU using tagging (e.g., network cookies)
    • Build closed control loop to analyze power and channel quality (related to A-CORD)
      • Adjust power
      • Spin up new BBUs
  • Core Slicing – Flexible allocation of resources to EPC components
    • Dynamic assignment of EPC resources (e.g. MME, SGW-C, PGW-C, SGW-D, PGW-D…) to slices
    • Resources can be dedicated or shared between slices
    • Coordinate core with RAN and Fabric slicing (e.g., vBBU gets slice information from slicing app to select appropriate core slice for incoming packets)
    • Build closed control loop to analyze singalling workload (related to A-CORD)
  • Connectionless RAN – Non-GTP based data forwarding model

    • Disaggregate eNB/SGW/PGW components to enable a centralized entity to manage new (non-GTP) data plane

    • vBBU data plane and service gateway data plane are controlled by ONOS apps

    • Get rid of GTP tunnels; replace with proactive OF rules in data path element

  • Edge Services – Demonstrate edge services taking advantage of capabilities

    • CDN – Utilize slicing to provide policy-based quality-of-experience

    • Public Safety – Utilize slicing to steer emergency traffic (e.g., police, fire)

    • AR/VR – Utilize slicing to meet high throughput needs of AR/VR

    • m-Health – Utilize slicing by dedicating resources to critical m-Health applications
