    267267=== 6.1  Configuration ===
    268268
    269 Fig 1-2a)  System Configuration with Three Servers  [[BR]]
     269A full WiMAX testbed system configuration utilizes three servers, per Figure 1-2a): [[BR]]
     270 ASNGW-C, that provides combined ASN GW functions, and includes a CLICK router. [[BR]]
     271 ASNGW-V, that provides virtualized ASN GW functions, for separate slices, with one VM assigned to each slice. [[BR]]
     272 OMF, that provides a full set of OMF/OML functions. [[BR]]
     273 
     274All servers run ubuntu Linux, and the ASNGW-V server implements kvm virtualization.  [[BR]]

    272 Figure 1-2a) shows the system configuration with three servers: [[BR]]
    273  ASNGW-03, that provides combined ASN GW functions. [[BR]]
    274  ASNGW-02, that provides virtualized ASN GW functions, for separate slices. [[BR]]
    275  OMF-04, that provides a set of OMF/OML functions. [[BR]]
    276 
    277 In some cases, a campus already has a set of OMF/OML functions, and would likely not require the OMF-04 server:[[BR]]
     279In some cases, it should be possible to combine the ASNGW functions into one server, for a WiMAX testbed system configuration that utilizes two servers, per Figure 1-2b).  [[BR]]
     280 ASNGW, that provides all ASN GW functions
     281 OMF, that provides a full set of OMF/OML functions. [[BR]]
     282 
     283Both servers run ubuntu Linux, and the ASNGW server implements kvm virtualization, with the combined ASN GW functions (non-virtualized) running in Dom0.  [[BR]]
     284
     285In some cases, a campus already has a set of OMF/OML functions, and would likely not require the OMF server:[[BR]]
    278286 Rutgers, WINLAB[[BR]]
    279287 Rutgers, Bush Campus[[BR]]
    280288 Polytechnic Institute of NYU[[BR]]
    281289 
    282 In many cases, it should be possible to combine the ASNGW functions into one server, for a total of two servers;  see Figure 1-2b.  [[BR]]

    286293
     294Finally, in many cases, it should be possible to combine all funtions within one server, for a WiMAX testbed system configuration that utilizes one server, per Figure 1-2c).  [[BR]]
     295 ASNGW_OMF that provides all ASN GW and OMF/OML functions. [[BR]]
     296 
     297This server runs ubuntu Linux, and implements kvm virtualization, with the combined ASN GW (non-virtualized) and OMF/OML functions running in Dom0. Note that this server must have a total of four ethernet ports to provide all of the requirted conenctivity. [[BR]]
     298
     299When this configuration uses a high-capacity (i.e., dual-CPU) server, it should have sufficient capacity for most installations.  Thus, it is the configuration that will be used for the initila installations at all campuses/sites.  [[BR]]
     300
     301Later, additonal servers can be added as necessary for capacity.  For example, if specialized functions such as video coding were included in a slice's VM, then additional capacity may be required.[[BR]]
