+1 If isolation is not the right term in IETF, I'd think a reasonable compromise is to use terms like 'sharing property' or a similar term. The extreme case of the attributes under this property disjointness in port/node/link/path level. This would be equivalent to private dedicated network level if you will. Other level of sharing can be enumerated thereof. Thanks.
