I set up a SDN using Mininet and Pox, now I need to measure statistics on certain links, such as packet loss. I was suggested to use Wireshark. I thought of filtering the arriving packets with tcp.analysis.packet_loss (don't know if it does work for this purpose) but this way I need a client-server tool to generate some TCP traffic to capture, not random TCP, but at least with progressive sequence number (so I can track packet loss). iperf is not good for me because I need a tool that doesn't generate "congestion" of a link. Other methods for measuring statics are ok. Can you help me, please?
- Scapy is a packet capture, analysis, manipulation and generation tool.
- Free, gratis & open source
- Cross platform including OS-X, Windows & Linux
- Easily send a set of packets with an incrementing field
- Analysis of the results, including graphical results, within the tool
- Scapy can have its own routing table rather than using the system one
- You can save your tests as scripts so as be able to retest later
- Lots of examples and a demo
