The tragedy is that BGP works ok. Its not broken. Its like a 30 year old pair of jeans that you know is worn out but you can’t bring your self to throw them away because of the memories.
Ok. Can we replace it ?
The challenge is building a community around that effort. Technically, there are dozens of ways to introduce a new protocol that would use modern efforts.
One problem is that everyone likes wearing 30 year old style of jeans and no one wants to throw them out.
We need to create a new fashion that everyone wants to copy/wear/consume. Thats the value of the IETF, its effectively the Gucci/Prada/Vogue of networking world. The people there create fashions, and then parade them down a catwalk to see if other people see their beauty.
A catwalk or something like it is needed to socialise ideas and build communities around.
The IETF and other standards bodies are mostly inadequate for the current rate of change. Where are the new catwalks ? The cloud companies is one catwalk but mostly they are working on what happens inside their data centres and building private WAN that bypass the internet.
And that proves my point that the internet is defective.
Where are the next wave of fashions going to come from ?
