Your text mainly refers to IntServ about which I make no comment. But the diffserv header field (formerly known as TOS in IPv4, known as Traffic Class in IPv6) is explicitly *not* global - it is meaningful per domain, and only makes sense in a domain that has been appropriately configured. See RFC 2474, 2475 and 3086 for more. Brian
