Title : QoS-guaranteed MPLS-based NBVPN with centralized resource controller
Author(s) : D. Li
Filename : draft-defeng-l3vpn-qos-crc-00.txt
Pages : 17

This document focuses on the QoS problem in NBVPN, analyses the QoS
requirement for NBVPN, the insufficiency of QoS guarantee in the
current NBVPN schemes in the related IETF work group, and proposes
a QoS-guaranteed NBVPN reference model with centralized resource
controller, in this model, some new concepts are introduced,
such as VPN Logical Bearer Network(VPN-LBN), VPN Centralized
resource controller(VPN-CRC); and mechanism of guaranteeing the VPN
QoS is explained in details, including address space, isolation
between VPNs, VPN route distribution, forwarding, interface
requirement signaling requirement, hybrid QoS-VPN, intra-domain VPN,
inter-domain VPN.

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.
