Title : Impairments And Other Constraints On Optical Layer
Routing
Author(s) : J. Strand, A. Chiu
Filename : draft-ietf-ipo-impairments-04.txt
Pages : 27

Optical networking poses a number challenges for GMPLS. Optical
technology is fundamentally an analog rather than digital technology;
and the optical layer is lowest in the transport hierarchy and hence
has an intimate relationship with the physical geography of the
network. This contribution surveys some of the aspects of optical
networks which impact routing and identifies possible GMPLS responses
for each: (1) Constraints arising from the design of new software
controllable network elements, (2) Constraints in a single all-
optical domain without wavelength conversion, (3) Complications
arising in more complex networks incorporating both all-optical and
opaque architectures, and (4) Impacts of diversity constraints.

In the body type:
"FILE /internet-drafts/draft-ietf-ipo-impairments-04.txt".
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.
