Title : An architecture for a gradual deployment of end-to-end
QoS on an Internet-wide scale (Virtual Service-aware
Network)

This document introduces Virtual Service-aware Networks (VSNs) as a
solution for inter-domain resource reservation with Quality-of-
Service (QoS) on an Internet-wide scale. A VSN is a single-domain
overlay network that consists of guaranteed QoS pipes. VSNs of
neighboring domains that offer the same level of QoS establish
peering relationships. As such, they form a network of QoS-enabled
networks with a specific (QoS) routing context. In this network,
admission control for traffic flows is performed in two phases. The
two-phase approach allows for the use of an off-path signaling
protocol, which enables the gradual introduction of this
architecture without changing the existing routers.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
