Geni wimax spectrum management

GENI WiMAX Spectrum Management

  • Agreement with Sprint

    • Sprint and Rutgers University have signed a master spectrum agreement

      encompassing all WiMAX sites, to ensure operation in the EBS Band.

    • An emergency stop procedure, in case of interference with Sprint service, has been agreed upon.

  • SciWinet GENI Mobile Virtual Network Operator (MVNO)

    - Partner with Sprint and Arterra (a Sprint partner) to create and operate an (MVNO) that serves the academic research community

    - The effort is led by Jim Martin, KC Wang and Ivan Seskar, to learn more:http://sciwinet.org

GENI WiMAX Portal Integration

  • GENI Portal accounts work with OMF login service.

  • GENI wireless resources can be reserved and used with Portal accounts.

  • WiMAX handoff tutorial @ GEC 20 used portal accounts to reserve ORBIT resources.

  • Expansion plan to include to all GENI WiMAX sites by GEC 21.

Compute layer concepts

Compute Layer Concepts

Service Extension Header

  • Provide easy extensibility/upgrade options for data plane.

  • ISPs can use in-network computing to provide value added services (e.g. caching, security, etc.).

  • Computing hosts running service instances strategically deployed at one or more Points of Presence (PoPs).

Compute layer examples

Compute Layer Examples

  • In-network processing and aggregation of sensor data:

    • sensed data from vehicles and other in-field sensors can be aggregated in the network by a compute layer service explicitly requested by the originator of the sensed data, thus reducing load on a centralized server.

  • Dynamic binding for Context GUID:

    • a local context defined as ‘unoccupied cabs in location X’ can be named using a GUID and resolved dynamically by an in-network compute layer service pulling information from a dispatch service to determine what end points qualify for delivery request messages.

  • In-line video transcoding:

    • More to follow…
