Slow WAN Segment

I have several locations linked by dedicated T1s back to a hub location - basically a star configuration.

Three of the four segments function well, while the fourth seems to slow down during working hours.  There are no more or less devices on the troubled segment than are on the good, but the slow segment shows ping times across the one hop to the hub exceeding 500ms consistently, sometimes peeking at 800ms.  Needless this to, this impacts the users on the segment.

What I would like to know is if there is a freeware/trial package I can install on that segment that will help me identify which device(s) are consuming the bandwidth.

Do you have a loop connected to your switches or routers?  Also if this is for personal use try www.omnipeak.com 

Another good tool is Ethereal.

What kind of routers do you have? If you have Cisco, I would recommend enabling Netflow and exporting the flow data to a NTOP box.
NTOP = http://www.ntop.org
You can do it all from your hub location and you won't have to put anything at the remote site.
