This post covers analysis of Google’s IP routing backbone

This post covers option to exclude CGNAT for the Google’s GGC cache traffic

This post covers information about Google’s plan to stop peering via route servers as well as possible speculation around why they are doing that.

This post analyses Google Cloud routing tiers and how they relate in the BGP world

I am in Bangalore for two days. While there are many things packed into these two days short schedule, one of the most exciting ones is Google Global Network India Innovation Summit. While Google has presented across various events in past talking about their AS15169 backbone, this is the first summit where they are covering it in detail and that too with the Indian context!

Must say that I find AS15169 quite fascinating on the BGP side of things. A massive network which follows “cold potato” routing i.e keeping the majority of traffic over IGP over larger locations, terminating BGP sessions on the virtual appliance with SDN backing, a pretty robust failover design with BGP + DNS taking care of server(s) and even entire PoP failing. I blogged about them back in 2020 here. So this should be fun!
