Network Requirements of Warehouse-Scale
Computing for Cloud Applications. Paulie
Germano; Google, USA. The ever-increasing
ubiquity and speed of Internet access has enabled
applications to move from the desktop
to a Web-based service delivery model. This
distributed model is commonly referred to as
cloud computing.The underlying infrastructure
consists of data centers housing massive
amounts of compute and storage resources.
These resources are not simply a collection of
servers but a carefully controlled and scheduled
distributed machine. The network plays an
critical role in maximizing the efficiency of the
most expensive component of these systems,
the servers themselves, by reducing constraints
on workload placement.The panel will consist
of experts in the cloud computing space and
will cover the unique network requirements,
design challenges, and desired future hardware

providing connectivity at data rates of up to 2.5
Gbps. In the meantime IEEE and ITU/FSAN
are defining the standards for next-generation

and discussions have started on how to push
access network speeds even further. This panel
will focus on the drivers and applications of
high speed PON systems. How do residential

OTuA4 • 3:00 p.m. Tutorial
Numerical Modeling in Optical Fiber
Design, John Fini; OFS Laboratories,
USA. Fiber design uses a range of
numerical tools to bring out physics
of how a novel design beats the
usual design tradeoff. Some recent
fiber types and applications highlight
different modeling approaches and
challenges.
John M. Fini has been modeling and
designing optical fibers at OFS Laboratories
since 2002. He developed resonant
mode suppression designs useful
in a number of applications, including
a successful commercial deployment
in fiber to the home. He uncovered an
important bend-induced limitation in
scaling of large-mode-area amplifier
fibers, and proposed new design rules
for mitigating this limitation. His work
on a wide variety of design problems
builds on several numerical codes he
developed in-house, and a curiosity
for novel physics that emerges from
microstructure and other advanced
fibers. He received his PhD at MIT in
2001, researching quantum solitons
and polarization mode dispersion.

FTTP Opportunities in Emerging Markets,
Benoit Felten, Diffraction Analysis. FTTP is
often considered to be a mature market development,
and therefore thought to have little
relevance for emerging markets. Things, however,
are not as clear-cut and aggressive FTTP
deployment in Emerging Asia (China, India,
Malaysia...), Middle East and Africa (Saudia
Arabia, Algeria...), Latin America (Brazil,
Chile...) and Eastern Europe (Hungary, Roumania,
Russia...) suggests that there are business
models for FTTP in emerging economies,
although the market rationale and deployment
models might be significantly different from
what we see in developed countries.

Tradeoffs and Drivers for Tunable/Colorless
Networks, Zeljko Bulut; Nokia Siemens

OpEx reduction through automation, and
more efficient bandwidth utilization are the
key drivers for the deployment of dynamically
reconfigurable optical networks. While some
key ingredients necessary to build tunable
ROADMs have been available for some time,
fully operational tunable networks are yet
to be offered and deployed. Beside tunable
ROADMs and transponders such solutions
must deliver a well-tuned control plane with
an integrated physical layer engine. A number
of technologies today are competing to enable
the most optimized and cost-efficient ROADM
architecture, each with its own inherent set of
advantages and disadvantages. We will discuss
the business drivers for tunability and explore
these key technologies and tradeoffs facing
equipment suppliers and network designers
when considering deployments of new optical
infrastructure.
