    11= 4.  Software =
    22
     3== NEC BTS ==
     4
     5The NEC BTS comes with firmware that sets its function;  it does not need to be installed.
     6
     7However, that are many parameters that must be configured; see (reference below).
     8 
    39== ASN-GW Controller ==
    410
    5 
    6 The ASN-_GW controller code is provided by NEC, and is based upon their commercial code.
    7 
    8 Three components are provided by NEC, in binary only:
     11The ASN-GW controller code is provided by NEC, and is based upon their commercial code.
     12
     13It was originally written in c, c++ and shell.
     14
     15It is a much simplified version of their commercial ASN-GW code, with several major functions removed, including:  all AAA;  handoff managment.
     16
     17Three components are provided by NEC, in binary only, totaling approx 25MB:
    918
    1019 * trapctrl - used for (snmp) alerts management   (not currently used)
    1120
    12  * asnctrl - Daemon process that is in charge of R6 control functions.  (well defined API)
    13 
    14  * epctrl - Daemon process that is in charge of R6 interface datapath.  (sets up GRE tunnel from Mobile Station (MS) to data path module (e.g., CLICK modular router)
    15 
     21 * asnctrl - Daemon process that is in charge of R6 control functions.
     22
     23                * opens a TCP port and listens; provides a well-defined API
     24                * see (* updated document) for details of the API
     25                * controls epctrl to setup data path
     26               
     27 * epctrl - Daemon process that is in charge of R6 interface datapath. 
     28 
     29                * sets up GRE tunnel from Mobile Station (MS) to GRE tunnel device, numbered gre_emc_xx
     30                * controlled by asnctrl
    1631
    1732These must currently be loaded with various libraries, including the SF Tables library; some could be eliminated.
    1833
    19 The asnctrl API can be found at:
    20 
    21 These is an ASN_GW Controller configuration file;  see below.
    22 
    23 
    24 [wiki:/Software/Create Create Debian Package][[BR]]
    25 [wiki:/Software/Configuration Create Package Site][[BR]]
    26 
     34There ia an ASN-GW controller configuration file;  see (reference below).
    2735
    2836== Data Path Module ==
    2937
    30 For Case 1, the Data Path Module carries data between the NEC IDU and tbe GENI Access Network.
    31 
    32 For Case 2, the Data Path Module carries data between the NEC IDU and tbe KVM VMs.
    33  
     38For Cases 1 and 2, the Data Path Module carries data between the NEC BTS and tbe GENI Access Network.
     39
     40For Case 3, the Data Path Module carries data between the NEC BTS and tbe KVM VMs.
     41
    3442Currently, the only supported Data Path Module is the Click Modular Router
    3543
     
    3846=== Click Modular Router ===
    3947
    40 The current supported Data Path Module is the Click Modular Router, v1.6.
    41 
    42 These is CLICK Modular Router configuration file;  see below.
     48The currently supported Data Path Module is the Click Modular Router, v1.6;  later, this is planned to be replaced with v1.8.
     49
     50The 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.
    4351
    4452=== Open Flow Switch ===
     
    4654== Control Module ==
    4755
    48 The Control Module sets the functionality of the NEC IDU, the ASN-GW Controller and the Data Path Module (e.g., CLICK Modular Router).
    49 
    50 For Case 1, the Control Module us the Simple Authorization Manager (SAM).
    51 
    52 For Case 2, the Control Module is the WiMAX RF Aggregate Manager.
     56The Control Module controls the functionality of the NEC BTS, the ASN-GW Controller and the Data Path Module (e.g., CLICK Modular Router).
     57
     58For Case 1, the Control Module is the Simple Authorization Manager (SAM).
     59
     60For Cases 2 and 3, the Control Module is the WiMAX RF Aggregate Manager.
