Flightplan demo & FDP video
Hi all, we're making the finishing touches on a demo for the Flightplan system for P4:
https://flightplan.cis.upenn.edu/
The demo runs completely in the browser and won't require you to install anything.
It features visualisation, animations, and graphs. It also links back to P4 code
that you'll see executing in the visualised network.
We're seeking feedback from the community on a mature beta. We've engineered it
to be intuitive, and faithful to low-level details, but additional feedback will
help us improve it further.
Please ping me off-list if you'd like to volunteer to try out the beta.
We're mindful that you're very busy, and to avoid taking too much of your time
we prepared some notes to quickly familiarise you with the demo and
to help structure the feedback to minimise the time you need to spend on it.
Heena (cc'd) did a great job on this demo, which we're pivoting into an online
teaching platform for networking -- you can see a video here: https://flightplan.cis.upenn.edu/SIGCSE_FDP.mp4
She's enthusiastic about working on SDN in industry after finishing her
MSc -- do reach out to her if you're looking for talent.
Hi Nik,
I am working on an experiment where I am making several parallel
connections between client and server machine.
Currently to check which packet accesses our register and modified or read
value, we largely rely on switch logs and log_msg function.
Sometimes for a large number of parallel connections, logs become so large
that it becomes hard to pinpoint errors in logic of the program.
So, my questions are:
- Whether Flightplan contains GUI support to visualize packet processing
events.
Like from the point it enters the port, then interacts with
parser->ingress->egress->deparser. - If not, are you planning to create some support in future to visualise
how different packets interact with pipeline elements like registers,
tables, etc.
If not, then perhaps see if your team can add a feature that records packet
interaction with pipeline elements and produce a video/graphics that show
how different packets interact with pipeline elements as time passes. I
believe such support would ease testing of their P4 program logic.
Regards
Sahil Gupta

Hi Sahil, thanks for reaching out. We've used a similar workflow for
debugging, as well as looking at the pcap files from some of the inputs
and outputs. The visualisation has helped us with debugging -- to get a
high-level idea of what's happening without digging into the detailed
information. The visualisation is generated automatically from the raw
information through an analysis that Heena (cc'd) implemented.
So, my questions are:
- Whether Flightplan contains GUI support to visualize packet processing
events.
Flightplan's only concerned with program splitting, but FDP (the
visualisation/demo system) does provide an in-browser interactive
visualisation of packet-processing events.
Like from the point it enters the port, then interacts with
parser->ingress->egress->deparser.
2. If not, are you planning to create some support in future to visualise
how different packets interact with pipeline elements like registers,

We don't plan to tackle that level of detail at present since we haven't
encountered the need for our work. But extensibility is one of FDP's
design goals, and if anybody else wants to take it up then we'd be happy
to support. If there's any particular feature that you feel would be
useful, then we'd be happy to share code for you to build on.
Thanks for the input,
Nik

We're releasing FDP soon -- we'll ping this list when we have further
info and I'll get back to a pending thread with Sahil.
