Do you know of any good tools for monitoring network traffic (preferably free) ? I'm hoping to get a better idea of any bottle-necks etc. with a view to possibly upgrading to Gigabit switches.<br />

tools for monitoring network traffic

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).
