There's never been anything like this before, and now here we go again.

Routes, tables, trees

Probably, I am getting old and sentimental, but again I couldn’t to resist the fundamental pages.
I had to take a closer look at FIB scaling issues and came across some papers.

GoBGP: BGP implementation in Go

There was an interesting challenge these days. I had to emulate BGP FlowSpec RFC 5575 peering and some announces to the DUT.
Unfortunelly, my testing and assurance software version doesn’t support this ability, but I have found out this suitable cozy project. Link below, thanks to developers.

Evaluation of an IP Fabric network architecture for CERN's data center

And another one CLOS design.
This stuff is not so modern, but quite interesting and illustrates some useful design approaches.

Testing methodologies: ITU-T Y.1564 & RFC2544

Unfortunately, I often note that there is a huge gap in understanding of network performance testing methodology.
Almost every related case goes down to “It seems it was quite better earlier”. No metrics, no anamnesis, so it makes me sad each time.

Just to be more confident I’ve gone through these canonical documents. Will keep it in mind for reference.

Meeting with Segment Routing

Finally, I’ve got a chance to take a dive into Segment Routing concepts, operations, and other aspects.
I was labbing with the migration scenario which is described in “DAY ONE: MIGRATING TO SEGMENT ROUTING”.

Have got a lot of fun, recommended.

I’m going to setup SRv6 topology as well, once I get the time.

Fiber Optic Cables Could Shake Up Our Understanding of Deep-Sea Quakes

Despite the remote and punishing environment, we already have a plethora of potential eyes on the bottom of the sea. There are around 400 fiber optic cables spanning the oceans.
These cables are already the backbone of the global Internet - what if they could be the backbone of deep-sea monitoring and research efforts as well?
