"modem_LPA_packetgen.pl" is a PERL script that generates modemLPA 
packets base on -02 of the modem link property advertisement draft, 
"draft-ivancic-mobopts-modemlpa-01".  NOTE. the IRTF mobops research 
group has recently closed down.  Futher advancements of the 
specification will be within some other yet to be determined group.

The script was used to demonstrate modemLPA by controlling the rate 
on a file transfer protocol.  The file transfer protocol used was 
Saratoga and is implemented in a PERL script. The Saratoga PERL 
script is available on SourceForge.  Search for saratoga and the 
script will be in the directory saratoga_v1_perl.   

This script  and the Saratoga implementation currently use a 
multicast address of 226.1.1.2. The all routers address of 224.0.0.2 
is suppose to be used, but the particular Linux machines we where 
running on did not want to pass 224.0.0.2 and we did not have 
sufficient time to determine why.  

Eventually, we hope to include code for GNU radios that implement 
modemLPA.
