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.

Back in 2017 Google shared details about Espresso which is their SDN solution for scaling up their routing. Saw this fascinating presentation from Google at SIGCOMM 2017. This blog post covers it in detail besides the talk. Key design principles for their routing platform Hierarchical control plane consisting of both global as well as local control. Global takes care of overall traffic flow, inputs coming from performance metric etc while local take care of failure of BGP sessions, port/device failure etc.
