v38 v39 89 89 === 4.4.1 Simple Authorization Manager (SAM) === 90 90 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).91 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). 92 92 93 93 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. 94 94 95 The SAM does not provide an API to the Experimenter, and does not require the presence of an OMF/OML instance. 95 The SAM deals with these parameters: MS MAC address; gre tunnel identifier; VLAN tag number. 96 97 The SAM does not provide an API to the Experimenter, and does not require the presence of an OMF/OML instance. 98 99 Configurations for the SAM are included within its code. 96 100 97 101 When a MS tries to register: … … 99 103 The SAM listens to the asntrl daemon to receive the registration request with MAC address of MS, and responds with "allow". 100 104 101 The SAM talks to the asnctrl, which talks to the epctrl, to create a GRE tunnel between the MS and the GRE tunnel endp point, 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. 102 106 103 107 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. … … 106 110 === 4.4.2 WiMAX RF Aggregate Manager === 107 111 108 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. 115 112 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). 113 114 The WiMAX RF Agg Mgr deals with these parameters: MS MAC address; gre tunnel identifier; VLAN tag number. 115 116 The 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. 127 128 In Case 2, the WiMAX RF Agg Mgr is controlled by the experimenter via Experiment Controller. 129 130 In Case 3, the WiMAX RF Agg Mgr is controlled by the VM Agg Mgr. 131 132 Configurations for the WIAMX RF agg Mgr are carried in the YAML file, see (reference below). 116 133 117 134 When a MS tries to register: 118 135 119 The WiMAX RF Agg Mgr listens to the asntrl daemon to find the request120 121 The WiMAX RF Agg Mgr talks to the epctrl to create a GRE tunnel between the MS and the CLICK modular Router122 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 beginthe 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. 124 141 125 142 126 143 == 4.6 OMF/OML == 127 144 145 For Cases 2 and 3, an instance of OMF/OML is setup on two VMs. 146 147 See (reference) for complete information on loading and initializing this software. 148 128 149 129 150 === 4.6.1 Aggregate Manager Services === 130 151 152 These 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 131 165 132 166 === 4.6.2 Experiment Control Services === 133 167 168 These services include: 169 170 * Experiment Contrl Srvc 171 * Exp App Repository 172 * Exp Description 173 134 174 135 175 == 4.7 KVM Virtual Machines == 136 176 177 For Case 3, a set of KVM VMs is setup on the KVM VM server. 178 179 One VM is assigned to process the data for each slice, and is associated with one VLAN tag. 180 137 181 138 182 == 4.8 VM Aggregate Manager == 183 184 In Case 3, a VM Agg Mgr is sum in a VM on the KVM VM server. 185 186 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. 187 188 In turn, the VM Agg Mgr talks to the WIMAX Agg Mgr to manage the MS for each slice. 189 190 In addition, the VM Agg Mgr works to prevent interference between slices. 191 139 192 140 193 === 4.8.1 Accessibility ===
