Programmer, Runner, Creator of Ostinato network traffic generator
I’m looking for a junior dev (or intern) to work with me on Ostinato - my network traffic generator / packet crafter product.
C++, Qt, Python, networking - lots of hands-on learning.
Please share if you know someone who might be a good fit🙏

After years of steady evolution, Ostinato 2.0 is finally here.
A big milestone for the project - modernized, faster, and built for what’s next.

Don't be! Use a mount.

We often see multiple Ostinato nodes in customer topologies. For a traffic generator like Ostinato, this is not just unnecessary but inconvenient! See how you can use a single Ostinato node in your labs (a boon in node-limited platforms!) (1/2)

10G, 100G, 400G -- that's the flashy part. But control protocols are slower and timeouts can be critical. While testing your network, don't forget to test the slow protocols (1/2)

🔥 BREAKING: Ostinato Turbo does 400Gbps!
It's 1518 byte packets, not 64 byte - much more testing and experimentation is still pending.
But still 400G is BIG!

To make Lua code also use enum names rather than integers, you can export the names as Lua global variables by regitering them as a property under a Lua namespace (table). (3/4)

You can support C++ enums by specializing the LuaBridge "Stack" template class for each enum type to pass enums from C++ to Lua functions - however Lua will treat it as an integer. (2/4)
