Paul, All; I have been thinking along the same
lines. Many of the experiments that may want to use GENI will be focused
on end equipment or end-to-end protocols, apps, etc, and therefore not
require the same granular flexibility that network-based experiments will
require. I suggest that there may be a partition (slice?) of GENI
substrate that is standardized and fairly stable for this sort of
experimentation. Concurrently, the ability to partition and slice at a very
granular level some pool of resources independent from the ‘standardized’
platform is required. I tend to think of this model in terms of virtual
private networks (VPNs). To Paul’s point, ATCA is certainly
one solution for unifying the substrate resources into a common chasis with
benefits of common power supply, hardware interconnection bus (can be bypassed
using port to port front panel connections) and a common low-level h/w
management capability (resource configuration & inventory). The openness
of ATCA would seem to simplify the development and introduction of new H/W and
S/W into the substrate, with the potential downside that the ATCA specification
could be overly constraining to some H/W development not yet mature enough to
fit into the necessary form factor. -Stu From:
substrate-wg-bounces@... [mailto:substrate-wg-bounces@...] On Behalf Of Paul Morton In addition to the use of modified
commercial equipment, what do people think about the use of a common hardware
platform as part of GENI D&P? One option is the ATCA (Advanced
Telecom Computing Architecture) platform (www.picmg.org/v2internal/newinitiative.htm),
or a new version the ATCA300 platform (www.rtcmagazine.com/home/article.php?id=100478&pg=1),
which offer an excellent opportunity for us to create a single unit that can
include all, or a choice of, physical layer technologies (processing, storage,
optical and wireless communications, switching and routing). Developing
such a ‘research’ platform could provide us full programmability of
the different substrate technologies. Jon Turner presented a processing
platform based on ATCA (see presentation at GENI Engineering Conference at www.geni.net), which already includes some of
the basic software infrastructure that may support other technologies. If
we could extend this approach to include different modules for all required
technologies, this would provide an excellent research platform for all GENI
folks to utilize. From an optical perspective, an
example could include modules that together provide a low-cost WDM
communication system plus an ROADM module for wavelength switching -
Universities in a region could potentially connect these platforms with dark
fiber to create their own network, building and comparing different topologies
and networking approaches to inform the next cycle of GENI design. Please respond to this suggestion,
plus, additionally, provide perspectives from other communities (e.g. wireless,
networking, …) on how such a platform could be developed and used in this
first cycle of D&P. An important aspect of such a D&P proposal
would be the true ‘cross layer’ R&D to be carried out on the
hardware. _______________________________________________ substrate-wg mailing list substrate-wg@... http://lists.geni.net/mailman/listinfo/substrate-wg |
