                  draft-ietf-nfsv4-mv1-msns-update-01

Abstract

   This document presents necessary clarifications and corrections
   concerning features related to the use of location-related attributes
   in NFSv4.1.  These include migration, which transfers responsibility
   for a file system from one server to another, and facilities to
   support trunking by allowing discovery of the set of network
   addresses to use to access a file system.  This document updates
   RFC5661.
