The largest chunk of bytes that a transport protocol can forward across specific medium is called MTU – Maximum Transmission Unit. If we speak about Ethernet, which is today the most common, he has by default 1522 bytes MTU. The story about MTU is that the MTU of specific protocol basically defines how much payload (or highest protocols headers + their payload) it can carry in its biggest packet, not counting his own headers. Putting more payload into single packet than the MTU allows will result in fragmentation, the process of slicing the frame into more smaller frames so that

He promised on behalf of the “mobile operator fraternity” that they will never throttle speeds.
A few weeks ago, I set out to the beautiful city of Vancouver’s convention center, along with a boatload of rocket turtles and a stellar team. It was a great time with a wonderful scenic view of the ocean. I’ve been at Cumulus a few months now, but I can’t help but enjoy looking around, seeing the friends I’ve made in the industry, and the friends and companies Cumulus has worked with over the years. It is exciting to have thousands of people coming together at OpenStack Summit Vancouver to work on a shared goal.
This year, we were lucky enough to have our very own Pete Lumbis take the stage with David Iles of Mellanox to present our joint solution around the latest SDN revolution, which is centered on creating efficient virtualized data center networks using VXLAN & EVPN.
In the next few paragraphs, I’ll share some highlights of the event, some photos, and a recap of that exact discussion. There was a lot to learn and discover, and I’m excited to share the details.
On our first day, lots of things were going on — we Continue reading

In preparation for Chrome’s Not Secure flag, which will update the indicator to show Not Secure when a site is not accessed over https, we wanted people to be able to test whether their site would pass. If you read our previous blog post about the existing misconceptions around using https, and preparing your site, you may have noticed a small fiddle, allowing you to test which sites will be deemed “Secure”. In preparation for the blog post itself, one of our PMs approached me asking for help making this fiddle come to life. It was a simple ask: we need an endpoint which runs logic to see if a given domain will automatically redirect to https.
The logic and requirements turned out to be very simple:
Make a serverless API endpoint
Input: domain (e.g. example.com)
Output: “secure” / “not secure”
Logic:
if http://example.com redirects to https://example.com
Return “secure”
Else
Return “not secure”
One additional requirement here was that we needed to follow redirects all the way; sites often redirect to http://www.example.com first, and only then redirect to https. That is an additional line of code I was prepared to handle.
I’ve done some Continue reading
