The title is clickbait, of course, (L3 routing is obviously not going away) but the essay is insightful.
Given that he mentioned Amazon, I'm surprised to see that there wasn't more in this essay regarding Amazon (and Googles) efforts to build their own routers. Also, a number of networking companies have started off by discarding all the legacy networking functions, and starting afresh (Juniper). It would be interesting to review the field and see who else is doing this, particularly in the last 5 years, and what their success has been.
Also - surprised that SDN only gets a brief mention in the conclusion - I thought, reading the essay, that's the direction he was going, and then it was over.
- ealexhudson 10y agoPresumably part of the solution he envisages is the rtbrick thing he's working on, which doesn't unstealth until next month. Feels like the start of a marketing trail to me.
- dang 10y agoWhat would be a better (i.e. accurate and neutral) title?

- ghshephard 10y agoFrom the conclusion: The router, and the dynamic control-plane, as basic forwarding paradigm of the Internet, remains undisputed. However, it gets challenged using new concepts like SDN and NFV, which promise much faster network adoption, automated control, reduced time-to-revenue, which all are good business solutions. In order for router designs to be competitive to those challenges, requires to re-imagine how router hardware and software get engineered. So, "Re-imagining the future of routers"
- dang 10y agoGood idea. Thanks! (All: suggesting a good title is the best way to complain about a bad one.)
- danellis 10y agoYeah, I thought SDN was the link to the title: "replace routers with L3 switches that populate their forwarding tables using OpenFlow queries", or something.
