ntop is a free opensource network traffic probe that shows the network usage. ntop is based on libpcap and can run on Linux/Unix and Windows operating system. ntop provides a very easy to use a web access to navigate through ntop traffic information and get a dump of the network status.

A group called the Traffic Squeezer project released an open source application that accelerates WAN network traffic. The Traffic Squeezer software uses lossless compression and other procedures to accelerate traffic on Linux-based network devices, and it's said a port to an embedded hardware version is planned.

By using my Network Monitoring Appliance we noticed a link in MRTG always under heavy load. On this link a lot of different traffic aggregates, so we decided to analyze of what quantities of protocols and therefore applications the cumulative traffic consists.

This how-to will teach you two commands, iftop and nethogs, that you can use to monitor network traffic on a Linux machine. You can use iftop to view traffic by individual connection, port, network segment, or remote host, which gives you a detailed accounting of all packets coming in and out of your machine.

mz (Mausezahn) is a versatile packet creation and network traffic generation tool. Using this tool You can Jam a Network.

This utility is used for Stress Testing of Networks and Firewall Testing. also for Finding weaknesses in network software or appliances.

IPTraf is a console-based network statistics utility for Linux. It gathers a variety of figures such as TCP connection packet and byte counts, interface statistics and activity indicators, TCP/UDP traffic breakdowns, and LAN station packet and byte counts. IPTraf is an IP traffic monitor that shows information on the IP traffic passing over your network.

The vaunted "$100 laptop" that Massachusetts Institute of Technology researchers dreamed up for international schoolchildren is becoming a slightly more distant concept.

"...They explain that there is research currently underway to address this issue using local-area wireless technology. This technology will allow vehicles to form an ad hoc network that can exchange timely information about traffic conditions, incidents, and accidents. The research team has a vision for such a traveler-centric, zero-infrastructure system they have named Autonet..."

So you got that shiny new Netbook, installed Linux on it and carry it along everywhere you go. The default enabled Firewall blocks incoming traffic so you feel safe when connecting to that anonymous WiFi network at your favorite fastfood restaurant.
