2 minutes read time Author: Justin Wilson Path hunting in BGP shows up when the network loses a route and has to figure out what comes next. You do not usually notice it during steady state. You notice it when traffic starts taking odd paths, and latency does not line up with what you expect. … Read more
Welcome to Packets Down Range #40. Lots of projects are going on here. I have been behind on getting these out.
The network edge is one of those terms that sounds precise until you try to pin it down. Ask a few engineers where the edge is, and you will get a few different answers.
Anyone who has been to a data center has run into the problem of not having the correct tool. In this article, I discuss various tools you should have
All of these data centers are not showing up by accident. They are the physical response to a change in how the internet is used.
A hyperscaler is defined by its scale, control, and consistency, not by branding or marketing. These organizations build and run compute infrastructure
TCP Authentication Option (TCP-AO) comes in. It is defined in RFC 5925 and exists to protect TCP sessions from spoofing and reset attacks.
Traffic rarely flows where you expect. BGP picks the “best” path, but that does not always mean the fastest or cheapest one.
As many of you know, I have recently dove headfirst into the 3D printing world. One of the things I came across was these little “dust covers” for Ethernet. https://makerworld.com/en/models/2065227-ethernet-dust-cover The jury is still out on how much dust and the like these will keep out, but thats not the intriguing thing about them. Let’s … Read more
From Cambium This email is to inform you that within the next ~24 hours, Cambium expects to release a new 25.0.1 as a replacement for 25.0. Cambium became aware of a longstanding issue for potential javascript execution on log pages. 25.0 was also discovered to have a bug with Technician level user access being allowed … Read more
For network engineers, data center design goes beyond switches and routers. The goal is to create an environment where failures are predictable and repeatable, not just to ensure basic functionality.
Effective network engineering is intentionally unobtrusive. When systems remain stable, support tickets are not generated. If routing functions correctly, inquiries are absent. When redundancy operates as intended, disruptions are imperceptible.
