Want to throw away this effort because of this one issue? > You think another solution won't have issues as well? I have to agree with Dino on this one. What we are talking about here is engineering. And more than that, its engineering with a large constraint set (i.e., the Internet). But engineering is about tradeoffs (well, its part art, part economics, and part luck too). So as Dino says, other solutions are going to have different tradeoffs. Some worse (for sure), and possibly some better. But it is clear that all of the solutions on the table (and likely any other solution) have complex issues sets, so we need to look at the bigger picture (rather than focus on any one issue in isolation). > We design for the optimal case and hopefully with experience and data > from operators more networks move to the optimal case. Right, and experience and data are the fundemental compliments to both research and engineering. > And later if we have to still solve the suboptimal case, we do > fragmentation. > > Can we agree with this?
