Introduction In yesterday’s Load Balancers Be Damned post, I demonstrated how adding Free Range Routing to servers could provide a way to do anycast load balancing without the need for expensive load balancers in some cases. What I didn’t really demonstrate well was the ECMP capabilities of the leaf nodes. I also punted on the required local health checking…

Introduction Companies such as F5, A10, and Netscaler (owned by Citrix) have built their respective businesses on the need for load balancing devices in the data center and other parts of the network. While these devices can make the sharing of the load of incoming service connections (eg: HTTP, DNS, etc) very easy, they also come with a sometimes…
Just a quick post. A short while ago, I wrote this post on how to get SLI working in Battlefield V. Dice released a new Battlefield V patch as of 13 February, 2019. In it, they attempted to deal with the Level of Detail (LOD) cheaters. I’m not going to go into the details of what the LOD cheat entails,…

Introduction I’ve spent a lot of years building up the audio setup on my gaming/editing PC. The parts are listed in the “Audio” section of this page. I figured I’d write up a long post describing what’s connected to what, why I did it the way I did, and the reason for purchasing the things I have. Bear in…

Introduction The release of Battlefield V hasn’t gone without quite a number of hitches. From various annoying bugs, to Dice’s incessant fiddling with weapon balance and damage models. And we’re only about a month in to it as of this writing. However, one important thing for those of us using NVidia’s SLI technology is: there’s no support for it. …
This is just a quick entry to wrap up my adventure with online streaming. It started like anything does: with nothing but an idea. I wanted to see if I could understand and figure out the technology behind streaming. I started on YouTube because they allow a near infinite upload bandwidth (turns out: it’s 51Mbit/sec) which made it possible for…

Introduction Over the course of the last few entries, I documented my learning of Cumulus Linux, and how to do simple VXLAN with an EVPN control plane using their OS. All of this was done in a virtual environment on my server or my Mac laptop. One of the challenges of doing this in an actual network is the…

Introduction Over the course of the last few weeks or so, I’ve been working with Cumulus Linux’s VX image on VirtualBox, on my Macbook Pro. As my virtual lab grew from a few VX images to the count of ten or so, my laptop began to complain. My laptop has a 4-core 2.8Ghz Core i7 with 16GB of RAM. …

Introduction In the last few of my blog entries, I discussed setting up a virtual lab using Cumulus’ VX image for VirtualBox. I then went through and got EVPN working, and finally showed how using VXLAN, we can consider dumping MPLS for L2VPNs. This entry will focus on automating the bring-up of a new switch running Cumulus, and it’ll…

Introduction In a previous entry, I described my thoughts on using VXLAN to replace MPLS for L2VPNs across a network. After reading through it, I decided to go back and re-do the configuration examples a bit, to make things a bit more like a backbone with several hops between the customer routers. This entry will outline those changes and…
