Dear sun-managers,

many thanks for your help concerning my problem. The solution is to use
a 100Mbit/s full duplex connection (dedicated ethernet point to point
link between the two machines to transfer the data).

Many thanks again to these people (I hope I do not forget anyone):

the additional serial cable)

My original question was :
I am sending live MPEG-2 video (8 Mbit/s) over a LAN (10Mbit/s) using
Optibase's MPEG-2 encoder system. During transmitting the signal from
workstation1 to workstation2 (using UDP) I have to transmit 2kbit/s in
the other direction (from workstation2 to workstation1 using TCP/IP). My

problem is that I have only one network card in each workstation.

Is there a possibility to send TCP/IP packets and UDP packets at the
same time, or do I have to use two network cards :
One for the MPEG-2 videosignal and one for the TCP/IP signal ?
