while looking through recent IETF meeting notes i found interesting idea - splitting OSPF area zero without incurring outage. it’s very interesting idea for flawless, in-service migrations.

on the other side, another OSPF concept that I was afraid somebody will bring up is… enabling FlowSpec capabilities. oh my…

also, overlay networking effort is gaining grounds, with architectural choices as well as security. it’s interesting how much longer it will take.

the I2RS interface is moving forward as well, which is a good sign. problem space is enormous, but progress here means we’re closer to deploying vast number of different SDN architectures.

so, despite the fact that some of the network engineers describe watching IETF work “just as much as interesting as watching the grass grow” - we’re moving ahead.
