 === 4.4.1  Simple Authorization Manager (SAM) ===
 
-The Simple Authorization Manager (SAM) provides configurations that set the functionality of the NEC IDU, the ASN-GW Controller and the Data Path Module (e.g., CLICK Modular Router).  
+For Case 1, the Simple Authorization Manager (SAM) talks to the ASN-GW Controller (asnctrl) and the Data Path Module (e.g., CLICK Modular Router, vi its configuration file).  
 
 The SAM sets up a single service for one set of Mobile Stations:  basic Internet Access, via one VLAN connected to the Outside Access Network.
 
-The SAM does not provide an API to the Experimenter, and does not require the presence of an OMF/OML instance.
+The SAM deals with these parameters:  MS MAC address;  gre tunnel identifier;  VLAN tag number.

 === 4.4.2  WiMAX RF Aggregate Manager ===
 
-The WiMAX RF Agg Mgr provides configurations that set the functionality of the NEC IDU, the ASN-GW Controller and the Data Path Module (e.g., CLICK Modular Router).  
-
-The SAM can set up a multiple servicse for multiple sets of Mobile Stations, via multiple VLANs connected to the Outside Access Network.
-
-The WiMAX RF Agg Mgr can get/set all parameters in the NEC IDU.
-
-The WiMAX RF Agg Mgr provides an API to the Experimenter, and for use via OMF, and it collects data and forwards it to an OML instance.
-
+For Cases 2 and 3, the WiMAX RF Agg Mgr replaces the SAM and talks to the NEC IDU, the ASN-GW Controller and the Data Path Module (e.g., CLICK Modular Router).  
+
+The WiMAX RF Agg Mgr deals with these parameters:  MS MAC address;  gre tunnel identifier;  VLAN tag number.
+
+The WiMAX RF Agg Mgr can:
+
+ * set up a multiple services for multiple groups of MSs, via multiple VLANs connected to the Outside Access Network.
+
+ * manage the NEC BTS, i.e., stop, start, restart.
+
+ * get/set all parameters in the NEC BTS.  Caution:  need to account for interactions;  see (spreadsheet)
+
+ * provides a REST-based API to the Experimenter, and for use via OMF.  This allows a MS to be added, removed, etc., and deals with MS MAC address and VLAN tag number.  Fallback is a default service like SAM.
+
+ * collects data and forwards data from BTS to an OML instance, including info on BTS, MSs, and events.  Typically, it queries BTS every 10 sec.
+
+In Case 2, the WiMAX RF Agg Mgr is controlled by the experimenter via Experiment Controller.
+
+In Case 3, the WiMAX RF Agg Mgr is controlled by the VM Agg Mgr.
+
+Configurations for the WIAMX RF agg Mgr are carried in the YAML file, see (reference below).
 
 When a MS tries to register:
 
-  The WiMAX RF Agg Mgr listens to the asntrl daemon to find the request
-
-  The WiMAX RF Agg Mgr talks to the epctrl to create a GRE tunnel between the MS and the CLICK  modular Router
-
-  The WiMAX RF Agg Mgr configures to the CLICK Modular Router to establish a path from the GRE tunnel to the Outside Access Network, and then restart the Router to begin the configuration. 
+  The WiMAX RF Agg Mgr listens to the asntrl daemon to receive the registration request with MAC address of MS, and responds with "allow".

 == 4.6  OMF/OML ==
 
+For Cases 2 and 3, an instance of OMF/OML is setup on two VMs.
+
+See (reference) for complete information on loading and initializing this software.
+
 
 === 4.6.1  Aggregate Manager Services ===
 
+These services include:
+
+ * CMC Srvc (dummy)
+ * Frisbee Server
+ * SaveImage Srvc
+ * PXE Srvc
+ * Result Srvc
+ * XMPP Server
+ * OML Server
+ * Inventory Srvc
+ * Dnsmasq
+ * DHCP 
+ * TFTP
 
 === 4.6.2  Experiment Control Services ===
 
+These services include:
+
+ * Experiment Contrl Srvc
+ * Exp App Repository
+ * Exp Description
+
 
 == 4.7  KVM Virtual Machines ==
 
+For Case 3, a set of KVM VMs is setup on the KVM VM server.
+
+One VM is assigned to process the data for each slice, and is associated with one VLAN tag.
+
 
 == 4.8  VM Aggregate Manager ==
+
+In Case 3, a VM Agg Mgr is sum in a VM on the KVM VM server.
+
+The VM Agg Mgr provides provides a REST-based API to the Experimenter, and for use via OMF.  This allows a slcie to be added, removed, etc., and is used to define the nature of the slice.
+
+In turn, the VM Agg Mgr talks to the WIMAX Agg Mgr to manage the MS for each slice.  
+
+In addition, the VM Agg Mgr works to prevent interference between slices.
