seem to figure out why. Here is the basics of the config:

By looking at your partial config and the NAT pool names these look
like Internet connections. If that is the case how is this a multiple
connection to a single network??

Hi all,
I have an OC-3 155Mbps UBR WAN link between two sites.
When I transfer files between these two sites using
windows explorer or ftp, I only have about 8Mbps.
Sprint told me I need to change the registry:
TcpWindowSize to get better throughput. Have anyone
experienced this before?
Thanks

This is a common complaint. Sprint is most likely correct, your
application simply can't utilize the bandwidth. The samller your window
size the less bandwidth you will utilize.
You can see this first hand by using ttcp between the two routers and
changing the window size on the router with

I once had a similar problem. The problem ended up being that the individual
files were so small that the ftp client simply couldn't get up to speed. It
would basically start slow for each file and accelerate during the upload.
They were so small, though, that basically it keeps starting over from
Yes, that would be the TCP Slow Start algorithm doing its job. I should add
that to my list of items that affect throughput. There's a good discussion
of it in RFC 2002, written by W. Richard Stevens, author of TCP/IP
Illustrated.
And surprisingly, I found a great page at Microsoft, of all

That should say RFC 2001.

Hi all,
I need to verify to see if the WAN connection is somewhat full-duplex
?
another word, for a 64kbps WAN connection, do I have 64K incoming and
another 64 K outgoing or the total of incoming and outgoing is 64 Kbps
?
Much thanks
Yes, WAN connections are almost always full duplex. I say almost
because there are probably some that I'm not aware of that are half
duplex.

When we talk of WAN encapsulations, are we talking just about the connection
from CPE to carrier's switch/entry point of cloud? Which encapsulations
deal with total path, end-to-end?
