    43 For Cases 1 and 2, the Data Path Module carries data between the NEC BTS and tbe GENI Access Network.
    44 
    45 For Case 3, the Data Path Module carries data between the NEC BTS and tbe KVM VMs.
     43The data path is built to support pure layer 2 (L2) traffic to and from the Mobile Stations (MSs), even though WiMAX is inherently an IP (L3) service.
     44
     45For Cases 1 and 2, the Data Path Module carries UL and DL L2 flows between a GRE tunnel on the NEC BTS side, and a VLAN tag on the GENI Access Network side.
     46For Case 3, the Data Path Module carries UL and DL L2 flows between a GRE tunnel on the NEC BTS side, and a VLAN tag on the KVM VM side.

    4748Currently, the only supported Data Path Module is the Click Modular Router
    48 
    4949Later, it is expected that an Open FLow Switch will be supported.

    5353The currently supported Data Path Module is the Click Modular Router, v1.6;  later, this is planned to be replaced with v1.8.
    5454
    55 The functionality of the CLICK Modular Router is set by its configuration file;  see (reference below).  This configuration file is initialzed and then updated by the Control Module.  With the current v1.6 implementation, the CLICK moduler router must be restarted after the configuration file is updated.
     55The functionality of the CLICK Modular Router is shown in Fig 4.
     56
     57It is based on a dynamically configurable L2 learning switch.
     58
     59Both UL and DL data paths are automatically created and installed when MSs associate.
     60
     61Data paths are setup by the CLICK configuration file;  see (reference below).  This configuration file is initialized and then updated by the Control Module.  With the current v1.6 implementation, the CLICK modular router must be restarted after the configuration file is updated.
