+It was originally written in c, c++ and shell.

+It is a much simplified version of their commercial ASN-GW code, with several major functions removed, including:  all AAA;  handoff managment.

+Three components are provided by NEC, in binary only, totaling approx 25MB:
 
  * trapctrl - used for (snmp) alerts management   (not currently used)
 
- * asnctrl - Daemon process that is in charge of R6 control functions.  (well defined API)

 These must currently be loaded with various libraries, including the SF Tables library; some could be eliminated.

+The currently supported Data Path Module is the Click Modular Router, v1.6;  later, this is planned to be replaced with v1.8.

+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.
