Do you have a loop connected to your switches or routers? &nbsp;Also if this is for personal use try <a href="http://www.omnipeak.com" rel="ugc">www.omnipeak.com</a>&nbsp; <br />
<br />
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.<br />
NTOP = <a href="http://www.ntop.org" rel="ugc">http://www.ntop.org</a><br />
You can do it all from your hub location and you won't have to put anything at the remote site.<br />

<div class="content wysiwyg-content">
I have several locations linked by dedicated T1s back to a hub location - basically a star configuration.<br />
<br />
Three of the four segments function well, while the fourth seems to slow down during working hours. &nbsp;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. &nbsp;Needless this to, this impacts the users on the segment.<br />
<br />
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.<br />
<br />
TIA!

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
