Hi, It took a little while to come up with a clear problem statement but we now have an I-D (http://www.ietf.org/internet-drafts/draft-ahmad- mter-problem-statement-00.txt (thanks to the authors)) that will hopefully trigger some discussion with the objective to see whether there is enough interest to pursue this work at the IETF. The draft has been structured so as to first show three scenarios where various recovery mechanisms could be used in combination. This does not aim to cover all possible cases but some pretty common deployment scenario for the sake of illustration. Then various Multi- TEchnology Recovery (MTER) issues are discussed. What is the objective of this work ? Let's start with the set of non-objective first ... * There is no intention to come up with protocols extensions that are being worked out in existing WGs (ISIS, IDR, CCAMP, ....) * Discuss implementation-specific issues Now the objectives ... What has been shown through the three MTER deployment cases making use of multiple recovery mechanisms in combination is the following: -> There are cases where being able to identify the root failure cause would significantly improve various recovery metrics such as the convergence time, required backup capacity, ... and so on. Do we need to work on such mechanisms at the IETF is an open question ? -> MIBs and OAM tools have been defined for most of the recovery techniques (IGP, BGP, MPLS FRR, GMPLS, ... ) and there are clearly no such tool for the aspects related to their combined use. It looks like the availability of such tools would help Service Providers to manage, tune and troubleshooting their network. Again, feed-backs from this ML are critical to see how to move forward and if the community expressed some interest. Thanks for your feed-backs. JP, Jean-Louis and Raymond. _______________________________________________ MTER mailing list MTER@ietf.org https://www1.ietf.org/mailman/listinfo/mter
