Each partition has at most one ULA. When the partition heals, a single ULA is retained. > Shouldn't this be a voting mechanism to retain the "most popular" existing > ULA? If I read the intent correctly, HNCP assumes that partitions are an exceptional occurrence, so when the partition heals an arbitrary ULA is retained (the one with the higher id). > Well even then you have the corner case of a split, stable operation, > remerge, where one of the two ULA prefixes will disappear. Yes. > Thoughts? HNCP already contains provisions for naming -- see Sections 8 and 10.5 of RFC 7788. The procedures described there are fairly primitive, and don't do anything to enforce stability. Its main flaw is that it doesn't provide a priority field, so there is no obvious way to prefer a human- configured name to an automatically generated one. If partitions are indeed a rare occurrence, then what is already in RFC 7788 should be sufficient. If you feel that this is not good enough, we could doubtless devise something more refined. -- Juliusz _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
