Re: Routed optical networks

Hi Etienne, Below is our (Cisco) definition of the Routed Optical Network. The goal, metro or long haul or subsea, is to reduce the number of control planes. By migration TDM traffic using CEM or PLE to the IP layer, you eliminate the OTN control plane and management. Eventually, when standards are

Re: Best Linux (or BSD) hosted BGP?

+lots. I've used a number of Linux routing thingies (BIRD, Quagga, VyOS/Ubiquiti, OpenBGPd, ExBGP), and FRR is (for me at least) by far the friendliest. It's trivial to spin this up on a cloud VM and start announcing a prefix. For doing something like Anycast though (where you are mostly just ann

Re: Routed optical networks

Hello Eve, Thank you for weighing in; I'm eager for feedback from the field. This eagerness stems from my work, over the past two years, to form my understanding of where current- and next-gen metro area networks are heading. I need this understanding to help academics in my field of specializatio

Re: Routed optical networks

Very helpful observations, Matt, thank you. How comfortably does the phrase "routed optical networks over Ethernet without ROADMs" sit with you? I mean: would you accept a limitation of "optical network" to the case of a network without optical layer switching (of the type done by add-drop multipl

Re: Routed optical networks

So right Jaredmagic has been in the NPU capacity increase that's driven the cost per 100G down on 1RU routers; and the integration of DSPs and more into QSFP-DD form factors at much lower power than expected. The standards for optical links are maturing as well, but we still have work to do on
