Title : Resource Unavailability (RU) Per Domain Behavior
Author(s) : G. Karagiannis, et al.
Filename : draft-karagiannis-ru-pdb-03.txt
Pages : 13
Date : 2006-10-20
This draft specifies a Per Domain Behavior that provides the ability
to Diffserv nodes located outside Diffserv domain(s), e.g., receiver
or other Diffserv enabled router to detect when the resources
provided by the Diffserv domain(s) are not available. The
unavailability of resources in the domain is monitored and detected
by proportionally marking packets whenever the current link rate
exceeds some pre-configured SLS agreed throughput (bandwidth)
threshold. It is considered that the SLS agreed throughput threshold
is not statically but loosely defined in order to allow a more
efficient utilization of the Diffserv domain(s) and a simpler network
management operation. This PDB can be applied in association with
either a single Diffserv domain or multiple neighboring Diffserv
domains, when a trust relationship exist between these multiple
Diffserv domains. This specification is denoted as Resource
Unavailability (RU) PDB and it follows the guidelines given in
[RFC3086].

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.
