Replay capture file with same cadence?

[Justin Z]

I have a packet stream from host-1 to host-2. These are both production, so I'm capturing a sample of the stream into a file, and now I need to "replay" that stream back onto a network interface so I can read it with a development-sandbox version of host-2.

The stream is data that's time-sensitive (it's a mechanical system, so data comes from position encoders, etc), so the playback needs to be at the same cadence/timing as the original stream.

Can Ostinato do that?

I'm capturing the packet stream via:

(echo "strm-name" 0,1,2 && cat) | nc host-1 <port> > capture_file

... so I would want to use capture_file as input, and replay the packets onto a network interface. Doable?

Hi Justin,

Were you able to replay the PCAP using the Ostinato pcap edit and replay functionality -  https://userguide.ostinato.org/pcap-replay/?
