There was a paper published by PacketDesign 1-2 years ago which suggested that features like MPLS fast-reconvergence were solving a problem which could be better done by getting IGP protocols to re-converge faster. There was some discussion that IGPs could be updated to support this (much bigger pipes means one could sending hellos much more periodically; running new forms of SPF which only re-computed the part of the tree which would change, etc.)
I see that there was an IS-IS ID published in 2000 that discussed these topics. The ID has since expired and so I don't know the real content of what was proposed. Looks like this work was also presented at Nanog 20. It doesn't look like this ID became an RFC. Anyone have an idea where the technology is around fast reconvergence? Are folks still thinking that it can be done by IGPs alone or must we use other mechanisms (MPLS fast-reconvergence, DPT/RPR, etc.)?
