2. GENI WiMAX Base Station Configuration

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

Fig 2-1) Case 1 WiMAX Base Station Configuration

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.

• No 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.

2.2 Case 2: Change to WiMAX RF Agg Mgr

• 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.

2.3 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.
