Hi ALTO folks, a bit of background on this draft. I'm a network
plumber, i.e., someone that has been dealing with optical pipes for the
last 12 years or so. Initially, we applied GMPLS techniques to SONET/SDH
networks and more recently wavelength division multiplexing (WDM) networks.
The application of GMPLS like techniques to SONET/SDH has seen wide
deployment by carriers in core networks world wide. GMPLS and PCE are
great control techniques within a network (sometimes segmented by
particular network layers), but do not make a good interface to the
"application layer". Some carriers offer "web portals" to allow optical
VPN customers to change the optical connectivity (bandwidth allocations)
amongst their sites. However such an interface would be both optical
transport layer and carrier specific.
The current ALTO protocol work contains many concepts and mechanisms
that would be useful for dealing with applications layer entities that
need to find out about large bandwidth availability to various locations
and the costs. The draft illustrates some use cases and additional
information and interfaces for "large bandwidth" users.
Best Regards
Greg B.

Hi,
We have submitted a new I-D:
http://www.ietf.org/internet-drafts/draft-bernstein-alto-large-bandwidth-cases-00.txt
This draft addresses use cases/applicability of the ALTO concept that would
allow network query, high bandwidth reservation to request network resources
from application stratum in data center/cloud networking environments.
We'd appreciate your input to this draft.
Regards,

Abstract:
This draft describes two generic use-cases that illustrate
application layer traffic optimization concepts applied to high
bandwidth core networks. For the purposes here high bandwidth will
mean bandwidth that is significant with respect to the capacity of a
wavelength in a wavelength division multiplexed optical transport
system, e.g., 10-40Gbps or more. For each of these generic use cases,
we present a generic optimization problem, look at the type of
information needed (query interface) to perform the optimization,
investigate a reservation interface to request network resources, and
also consider enhanced availability and recovery scenarios.
