Ostinato 2.1 will have more stream stats improvements:

1. Remove limitation that Tx stats are 0 during Transmit
2. Manual or Auto refresh stream stats during transmit
3. Shows stream names in addition to GUIDs

With Ostinato 2.0 we reorganized the stream stats view from a wide table to a tree view which was a major improvement.

The best way to learn something is to practice it - we all know this.

That's why labbing is important for network engineers for cert study.

If you are learning or curious about Path MTU discovery, our latest Ostinato guide shows how to lab this feature.

Technically speaking, only hardware can detect bit error rate as software only sees frames/packets. But you can use the packet drop/error rates to approx it - or check the NIC stats which has more detailed stats than what the Linux kernel exports.

Why Ostinato TX uses only one core - or does it? Why Ostinato TX uses one CPU core per port and when it actually uses multiple cores. Includes performance optimization tips and Turbo Transmit details.

"I have a multi-core CPU, but Ostinato is using only one core while the rest are idle" - this is a common performance question we get from customers.

Ostinato can emulate a host device - multiple devices in a subnet actually.

Not just that - you can even emulate multiple networks behind a single Ostinato port.

Our latest guide shows you how!

That's where Open Build Service (OBS) really shines! One set of packaging scripts to build for multiple Linux distros.
In my latest blog post, I show how to enable RedHat's multi-repo layout in OBS for RedHat (and clones). (2/3)

As a cross-platform software, Ostinato runs on Windows, MacOS and Linux. But there's not one single Linux, but various distros - Ubuntu, RedHat etc. DEB/RPM packages need to be built individually for each distro. (1/3)

Streams vs Flows - if you have only used iperf before, the distinction may not be clear. Our latest guide clarifies this concept.
