Stephane, Much progress on the topic has been made since that much preliminary Infocom paper. So here come more up-to-date reference points to compare:
Graceful Convergence in Link-State IP Networks F. Clad, P. Mérindol, J.-J. Pansiot, P. Francois and O. Bonaventure In IEEE/ACM Transactions on Networking, 2013 documents the most optimised algorithm known so far for the link shutdown case, with extensive simulation results and performance analysis. Graceful Router Updates for Link-State Protocols F. Clad, P. Mérindol, S. Vissicchio, J.-J. Pansiot and P. Francois In proceedings of IEEE ICNP 2013, Göttingen, Germany, October 2013 provides an algorithm to do the same in the node shutdown case, smarter than doing one link after the other.
