Hi Rohit, I am not claiming that with flooding optimizations the network meltdowns/failures, which the paper observes "could" be typical(its been some time since I read the paper though), would be solved, not optimizing aggravates the problem further. The same is true about our draft. Though flooding optimizations by themselves wont suffice they do help solve part of the problem. I think if "flooding optimizations" can be achieved without cluttering up the spec/code, it would be helpful, besides from the two documents I refer to it could mean the problem has been seen by the operators too(though I am not sure of the no workarounds in site part of it).

One of our =>drafts "Congestion Avoidance and Control for OSPF networks" talks about =>problems that have been caused by flooding overload in production networks. [snip] Vishwas, I am familiar with Aman's work. The problem identified there was that of (a) sub-optimal network/ospf configuration and (b) broken router. This does not ofcourse justify building new protocol mechanisms, thereby complicating the protocol. I will look at the congestion again to see if/why it concludes otherwise. Regards, --rohit.
