- Accurate time at packet capturing nodes. What is the software which will give us adequate time accuracy and time resolution? Although VMs are probably not the best machines to keep accurate time, we should try to install the software which will be used in our final solution.
- Traffic generation software:
- Traffic capturing software (capable to capture all the significant parts of a packet): just tcpdump/tshark or whatever at the very begining (in order to emphasize their limits)?
- Mechanism to transport captured traffic from packet capturing points to the management station: just rsync or whatever at the very begining?
- Software needed to emulate delay, jitter, loss
- netem – check if this is sufficient for us, and if it can be installed/used
- Compare our statistics with basic active measurements (that can be also sniffed)?
We have to make:
- Addidional node configuration to match all our experimentation goals (additional VLANs, define final testbed and service topology)
- Application/script which extracts only the necessary data from the packet capture
- Application/script which transports captured data to the central management station
- Define method and create and application/script which analyses gathered results and provides results in the human readable form (no nice GUI though).
