    v38 v39  
    8989=== 4.4.1  Simple Authorization Manager (SAM) ===
    9090
    91 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). 
     91For 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). 
    9292
    9393The SAM sets up a single service for one set of Mobile Stations:  basic Internet Access, via one VLAN connected to the Outside Access Network.
    9494
    95 The SAM does not provide an API to the Experimenter, and does not require the presence of an OMF/OML instance.
     95The SAM deals with these parameters:  MS MAC address;  gre tunnel identifier;  VLAN tag number.
     96
     97The SAM does not provide an API to the Experimenter, and does not require the presence of an OMF/OML instance. 
     98
     99Configurations for the SAM are included within its code.
    96100
    97101When a MS tries to register:
     
    99103  The SAM listens to the asntrl daemon to receive the registration request with MAC address of MS, and responds with "allow".
    100104
    101   The SAM talks to the asnctrl, which talks to the epctrl, to create a GRE tunnel between the MS and the GRE tunnel endppoint, number gre_emc_xx.
     105  The SAM talks to the asnctrl, which talks to the epctrl, to create a GRE tunnel between the MS and the GRE tunnel endpoint, number gre_emc_xx.
    102106
    103107  The SAM configures changes the configuration file for the CLICK Modular Router to establish a path from the GRE tunnel endpoint, to the VLAN tag, and then restarts the Router to execute the configuration.
     
    106110=== 4.4.2  WiMAX RF Aggregate Manager ===
    107111
    108 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). 
    109 
    110 The SAM can set up a multiple servicse for multiple sets of Mobile Stations, via multiple VLANs connected to the Outside Access Network.
    111 
    112 The WiMAX RF Agg Mgr can get/set all parameters in the NEC IDU.
    113 
    114 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.
    115 
     112For 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). 
     113
     114The WiMAX RF Agg Mgr deals with these parameters:  MS MAC address;  gre tunnel identifier;  VLAN tag number.
     115
     116The WiMAX RF Agg Mgr can:
     117
     118 * set up a multiple services for multiple groups of MSs, via multiple VLANs connected to the Outside Access Network.
     119
     120 * manage the NEC BTS, i.e., stop, start, restart.
     121
     122 * get/set all parameters in the NEC BTS.  Caution:  need to account for interactions;  see (spreadsheet)
     123
     124 * 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.
     125
     126 * 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.
     127
     128In Case 2, the WiMAX RF Agg Mgr is controlled by the experimenter via Experiment Controller.
     129
     130In Case 3, the WiMAX RF Agg Mgr is controlled by the VM Agg Mgr.
     131
     132Configurations for the WIAMX RF agg Mgr are carried in the YAML file, see (reference below).
    116133
    117134When a MS tries to register:
    118135
    119   The WiMAX RF Agg Mgr listens to the asntrl daemon to find the request
    120 
    121   The WiMAX RF Agg Mgr talks to the epctrl to create a GRE tunnel between the MS and the CLICK  modular Router
    122 
    123   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.
     136  The WiMAX RF Agg Mgr listens to the asntrl daemon to receive the registration request with MAC address of MS, and responds with "allow".
     137
     138  The WiMAX RF Agg Mgr talks to the asnctrl, which talks to the epctrl, to create a GRE tunnel between the MS and the GRE tunnel endpoint, number gre_emc_xx.
     139
     140  The WiMAX RF Agg Mgr configures changes the configuration file for the CLICK Modular Router to establish a path from the GRE tunnel endpoint, to the VLAN tag, and then restarts the Router to execute the configuration.
    124141
    125142
    126143== 4.6  OMF/OML ==
    127144
     145For Cases 2 and 3, an instance of OMF/OML is setup on two VMs.
     146
     147See (reference) for complete information on loading and initializing this software.
     148
    128149
    129150=== 4.6.1  Aggregate Manager Services ===
    130151
     152These services include:
     153
     154 * CMC Srvc (dummy)
     155 * Frisbee Server
     156 * SaveImage Srvc
     157 * PXE Srvc
     158 * Result Srvc
     159 * XMPP Server
     160 * OML Server
     161 * Inventory Srvc
     162 * Dnsmasq
     163 * DHCP
     164 * TFTP
    131165
    132166=== 4.6.2  Experiment Control Services ===
    133167
     168These services include:
     169
     170 * Experiment Contrl Srvc
     171 * Exp App Repository
     172 * Exp Description
     173
    134174
    135175== 4.7  KVM Virtual Machines ==
    136176
     177For Case 3, a set of KVM VMs is setup on the KVM VM server.
     178
     179One VM is assigned to process the data for each slice, and is associated with one VLAN tag.
     180
    137181
    138182== 4.8  VM Aggregate Manager ==
     183
     184In Case 3, a VM Agg Mgr is sum in a VM on the KVM VM server.
     185
     186The 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.
     187
     188In turn, the VM Agg Mgr talks to the WIMAX Agg Mgr to manage the MS for each slice. 
     189
     190In addition, the VM Agg Mgr works to prevent interference between slices.
     191
