2. GENI WiMAX Base Station Configuration

2.1 Case 1a: Start with Simple Authorization Manager (SAM)

This is the simplest configuration, and is the configuration implemented by the native Rutgers base station kit. It is characterized by:

  • The Simple Authorization Manager (SAM) is used as the control module; it has no API.
  • An instance of OMF/OML is NOT required.
  • Only a "default service" is provided, that provides all registered Mobile Stations (MSs) with access to one VLAN, that typically provides a DHCP service and allows the MS to access the Internet.

2.2 Case 1b: Install WiMAX RF Agg Mgr

  • The Wimax RF grid service provides the connection manager functionality of Simple Authorization Manager as well as a web based interface to query and set all BTS parameters including client parameters as heard by the BTS.

  • An instance of OMF/OML is required.
  • Only a "default service" is provided, that provides all registered Mobile Stations (MSs) with access to one VLAN, that typically provides a DHCP service and allows the MS to access the Internet.

2.3 Case 2: Integration with OMF/OML for experiment support

  • The WiMAX RF Agg Mgr is used in place of the SAM as the control module; it provides an API to setup the offered service(s), which is used by the Experimenter via OMF/OML.
  • An instance of OMF/OML is typically provided.
  • Multiple services can be provided, plus a "default service" , where each service provides selected Mobile Stations (MSs) with access to one VLAN; registered MSs that have not been selected are provided with access to one VLAN, that typically provides a DHCP service and allows the MS to access the Internet.
  • Each service can be associated with a GENI slice, but there is no support for slice configuration.

2.4 Case 3: Add KVM VMs and VM Agg Mgr

  • To upgrade to this case, a server is added and KVM VMs are installed on the server; a VM is typically used to process data for each slice.
  • A VM Agg Mgr is added, which is used to setup each slice by configuring the VMs and by utilizing the WiMAX RF Agg Mgr API.
  • Each slice can implement one service, and the VM Agg Mgr works to minimize interactions between the services.
