Excellent Tutorials and Talks on Networking/Peering/Datacenter Ops. & Tools from NANOG Events
 Collected these for members of our network/NOC/Datacenter 
 infrastructure team. May be of interest to you. Feedback welcome.

Optics, high speed/low latency transmissions, long haul connections, undersea cables & physical limits today and in the future:

  • Tutorial: Everything You Always Wanted to Know About Optical Networking – But Were Afraid to Ask
    https://www.youtube.com/watch?v=Y-MfLsnqluM & <Slidedeck>
    (Introduction to optics and all relevant topics: fiber types, wavelengths, O,C&L-band, WDM: CWDM vs DWDM, ROADM, amplification, MUX/DEMUX, optical switches, OTN, open line systems, optical taps & splitters, monitoring, dispersion, attenuation, SNR etc)

  • Optical Fiber Capacity Limits - Where Do We Next?
    https://youtu.be/prC-1lZ_wdk?si=Oap9E1vImZ7GQYXk
    (Absolute recommendation! Topics include: How do glass fibers work between continents, what are the limits as a rule and in the laboratory, what new fiber types & trunks are there, what is Raman and doped fiber, why/from when and how do you have to amplify it, why Single mode preferred, 1Pbit/s via fiber is possible? 250Tbit common? and much more. enjoy!)

BGP on the Internet, at Exchange Points versus BGP in the data-center:

Datacenter BGP (EVPN, VXLAN, DCI, Overlay Networks, Private Peering, Interop. etc.)

MPLS & Traffic Engineering: Virtual Leased Lines (VLL)/Ethernet Circuits,...:

 old: VPLS (L2VPNs/L3VPNs)
 new: EVPN & Segment Routing

Caching at the Edge and the Border:


[might be extended in the future]

feel free to leave comments, suggestions, feedback and especially things I've might missed in the comment section below. (theoretically you can also use git as this gist is just another git object markdown file)
