We've gotten to the place that it would be nice to see how some commercial stacks compare.
-
The number one request I get for BGP Performance testing is to do filtering tests.
-
What happens if we try to test with 1000 Neighbors with full internet routes to open source BGP stacks?
-
making changes to the network safely
-
these posts are as much about me figuring out how to test BGP stacks as they are about actually measuring those stacks
-
In this post I'm addressing the the issues of testing with real internet routes so we get to stress the best path algorithm
-
After I published the post on measuring open source BGP stacks I was embarrassed after I realized how haphazard the testing was.
-
As you notice what breaks, what is hard to change, what pages you in the middle of the night, think about how to make the network simpler.
-
Open source BGP stacks are very important, but I don't think they get the love they deserve. I thought I'd like to quantitatively compare them.
-
It's very important that the networking team that owns the design, build, and operations of the network is responsible to know that the network it is operating is not working before it's users do.
-
Do you ask "Is my network healthy?" Do you know how to answer that well?
-
closed loop automated testing is key to making safe network changes
-
Networks are complicated, have lots of moving pieces, and are hard to understand. How do you explore your network now to find out what protocols you are using, or if is is operating as expected?
-
Is my network behaving as I think it should be?
-
Getting the network out of the way was an important concept for me to think about in my AWS career. Spending money on networking saves money overall, assuming you use that money to get the network out of the way.

A screencast demonstrating path tracing in Suzieq
-
Our 0.8 release has (finally!) added a GUI.
-
Observability is useful for more than troubleshooting
-
There is a lot going on in the field of the highest speed network ASICs.
-
An evaluation of different SSH libraries in Python
-
An evaluation of different approaches to perform IP's longest prefix match in pandas.
-
In general I dislike load balancers and IP multicast ... But they've been very important for my career.
-
One of the things I've learned recently is that OSPF can't be used for Clos leaf-spine networks. I've heard that it can't keep up with the scale of the modern network. ... This is a shock to me since we built large OSPF Clos networks a decade ago.
-
In this post we look at an example of simulation in another field and think about how we can apply that to networking.
-
In this post we discuss how Suzieq handles time
-
In this post we interrogate Suzieq with 5 questions
-
Suzieq is new software for Network Observability. This is an exploration of using Suzieq to understand your network.
-
In this post, we introduce a new open source tool we've authored called Suzieq.
-
Simulating network design is really important and we can use cloud computing to try things out.
-
If you're a network operator faced with Kubernetes arrayed on the other side, what do you do?
-
What is an Elegant Network and why does it matter?
-
In this post, we’ll consider the effects of a high switch port count chip such as Tomahawk 4 on the Clos topology
