Great info, thx. Using this opportunity to rant about city-wid networks, I'd have done something so different than what the governments and ISPs have inflicted on us, substituting redundancy for reliability.
I'd have used bog standard ethernet over fiber instead of gpon. The only advantages to gpon were that it was a standard normal folk (still) can't use, it offered encryption to the co-lo, and the gpon splitter at the neighborhood cabinett could be unpowered, and a telco-like design could be made telco-level reliable.Theoretically. In reality it constrains the market and raises the price of gpon capable gear enormously, thus creating a cost for the isp and a healthy profit margin for the fiber vendor. Neighborhood cabinets would be cross connected north, east, west, south, uplink1, uplink2, thus rendering the entire network immune to fiber cuts and other disruptions of service and allowing competition for service from multiple isps. Fiber or copper or wireless (cell) to the building from there. Your neighbor would be one hop away. Local cellular or wifi would spring out of smaller towers distributed above those cabinets. Lest you think I'm entirely insane, that's how amsterdam's network was built out 10+ years ago. https://arstechnica.com/tech-policy/2010/03/how-amsterdam-was-wired-for-open-access-fiber/ I'd have avoided MPLS, and gone with something like 64xlat to deal with the ipv4 distribution problem. There'd be a secure routing protocol holding the city-wide network together. And there'd be ponies. Lots of ponies. _______________________________________________ Cake mailing list [email protected] https://lists.bufferbloat.net/listinfo/cake
