Re: [rrg] Next topic?

Hannu, 
please admit that Columbus routing is part of multipath forwarding and I will admit that I deliberately obstained from submitting a 01-version of the TARA-draft that contained in detail how to do Columbus routing based on TARA.

I don't know the secret why DV is such sacrosanct but I know for sure that enhancements for routing via more and more remote nodes would blow up DV.

Offlist I received comments about what to do with so many alternative paths, when provided. Indeed, they need to be utilized for the overall benefit
(traffic balancing, congestion avoidance, congestion handling). This however would need a rearview mirror i.e. knowledge about upstream paths from where the traffic comes from. Again: not possible based on DV.

Based on my reading of TARA it was all about geographical addressing.

Obviously no one, because this was a main goal of ignored TARA: multipath forwarding based on a network graph which is composed of  

inter- AND intra-network links and which  not only comprises  ECMPs but also  detouring paths  via equidistant or even more remote routers.

Hi, 

What about doing some work in multi-path routing in the inter-domain? 
i.e. enabling a router to use multiple paths with potential different characteristics to forward packets across domains. 
Would people find this topic interesting? 

regards, marcelo
