Guy,
Are you aware of the product called DirecPC Enterprise Edition, which
upgrades your existing PES hubs to allow throughputs on outroute
of upto 2Mbps? I don't have a lot of details on that, but you might want
to talk to your contacts at HNS about the feasibility of this for
your application.

>>Hi Jack,

>>Couple more details :
>>- we have an inroute of 128 kbps and an outroute of 512kps.
>>- ftp traffic is carried over Transaction Reservation on VSAT
>>
>>Doing an ftp , I get 30 kps on the outroute and less on the inroute (19
>>kps). Although I'm not the only user on the VSAT network, I expected a
>>higher performance (the usage is only 20 % on inroute and 30 % on
>>outroute).
