Title : Comparison of Proposed PCN Approaches
Author(s) : A. Charny, et al.
Filename : draft-charny-pcn-comparison-00.txt
Pages : 33
Date : 2007-11-9
Several, sometimes conflicting proposals have been offered for the
consideration of the PCN WG regarding PCN internal node and PCN edge
node behaviors. Based on the WG charter, the WG needs to make a
decision on which of the proposed PCN-interior-node and PCN-boundary-
nodes behaviors to endorse. The primary goal of this draft is
twofold. First, we attempt to summarize the functional differences
between the proposed alternatives. Second, we provide a brief
summary of performance evaluation results. Finally we propose a view
on how a (parameterized) specification of the PCN-interior-node
metering and marking function can be described to enable several of
the proposed behaviors. We argue that if this parameterized
specification is used for specifying the PCN-interior-node behavior,
then it can support a range of behaviors at the PCN-boundary-node.
The decision on which of the PCN-boundary-node behaviors to choose
can then be considered separately. We also discuss complexities
associated with choosing such uniform approach.

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
