Bundled DNS Name Redirection

More and more internationalized domain name labels [RFC3490] appear in the DNS trees.  Some labels [RFC3743] are equivalent in some languages.  The internet users want them to be identical in the DNS resolution.  For example, color.exmaple.com==colour.example.com.  The BNAME represents for bundle names. This document defines a new DNS Resource Record called "BNAME", which provides the capability to map itself and its subtree of the DNS name space to another domain.  It differs from the CNAME record which only maps a single node of the DNS name space, from the DNAME which only maps the subtree of the DNS name space to another domain.
