In my understanding, this is not strictly true - any 'systematic' code will have the unencoded chunks remain available in this manner, and any non- systematic linear code can be transformed into a systematic code with the same minimum distance. Fountain codes are often explicitly constructed to maintain this property, as in the case of RaptorQ [RFC 6330]. https://en.wikipedia.org/wiki/Systematic_code -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
