UDP packet frequency problem.

Hello
I have a query / problem regarding the "shaping" of udp.
I have is 2 applications talking to each other on ports 10000 - 29000 via
UDP.
The problem I have is application 1(Solaris 8 system) is sending packets in
very tightly spaced intervals then taking a break and doing it again.
Application 2 (Custom system running who knows what) can only handle
constantly streamed packets.
I need a packet spacing of about 5 milliseconds (not much bandwidth being
used).
Does anyone know what sort of set-up could do this or have any other
suggestions?

What I was thinking was using a Linux system with transparent packet
forwarding between the two to "smooth" the data from 1 to 2.

I have tried several settings on the Solaris system via ndd but eventually
traced it back to the application not the OS.
Both of the applications can not be changed.

Regards,
Harv.

Not my software, I am the admin with the heartburn.
One of the worst systems I have ever had to get working.
Luckly I only need it to work for about 8 hours then I can throw it
away as it only for a short term test.
Best bit is I can have zero packet loss.

With a token ring network, you could calculate the maximum delay. However,
with ethernet, you can't do that, though using switches will minimize the
problem.
