Coming
soon: High-speed network, high availability

Deploying a new enterprise network capable of meeting
the performance demands of an increasingly complex and forward-thinking
organization like Emory is one of the critical foundation issues
currently being addressed by the Office of Information Technology.
The new network will provide the backbone for communicating
across the campus and with colleagues around the country and the
world.
Whether in the research
lab, the classroom or one of Emory’s health care facilities, this project
will benefit all campus users by improving network capacity, performance, reliability
and security.
By increasing network capacity from one gigabit to
10 gigabits, the new network core will be able to better support
high-bandwidth,
low-latency application demands
such as medical imaging, high-definition video and central storage and backup.
With a new, more flexible architecture, the network also will allow for cost-effective
solutions to some long-standing challenges.
For example, it could allow Emory to quickly and cost
effectively meet regulatory requirements (e.g., HIPAA restrictions)
for transporting
patient health information.
In the past, this would have required an entirely new network with dedicated
hardware and fiber-optic cable; with the new advanced core, we can create a secure
virtual network using the same hardware, thereby reducing cost and expediting
delivery.
Other improvements include eliminating any single point
of failure, both internally and externally. Within the campus network,
all
of the critical network devices
will be joined together in a cube-like structure—each connecting to at
least two other devices. For Internet connections, the new design will use two
distinct but pooled Internet service providers (ISPs). One router or ISP failure
will not bring down network communications, and advanced networking software
will allow in-service upgrades without disruptions in service. This same technology
isolates software bugs and mitigates the risk of one software failure bringing
down an entire router.
Implementation of the new core is in progress, under
the leadership of Network Communications (NetCom) with executive
sponsorship from
Rich Mendola, vice president
for information technology and CIO. NetCom is testing and installing the new
routers in key locations across campus and developing a migration plan for moving
links from the old network to the new advanced core. The goal: full deployment
of the new core infrastructure by August 2006.
“In the field of life science and bioinformatics, there is a marked influence
on sharing data and the use of remote resources,” said Walt Hultgren, chief
information officer for Yerkes National Primate Research Center. “The equipment
and software needed to manage large data sets is not cheap; you want to leverage
as much as possible the things that other people are doing, both in the sense
of sharing resources and learning from the data and information of others. It’s
almost the cost of admission into world-class research.”
Recently awarded National Institutes of Health funding
for the Biomedical Informatics Research Network (BIRN) initiative,
Yerkes was selected
to head up a scientific “test
bed” for nonhuman primate research in collaboration with 21 U.S. universities
who share brain-imaging data. Such collaborative research involves network
sharing of large digital files, where a typical MRI or PET scan generates from
0.5 to
2 GB of data.
“The goal of the BIRN project is to serve as a data repository of biomedical
(ranging from imaging to microarray) data and data-analysis software, to facilitate
the sharing of data nationally and internationally, to enhance translational
research, and to speed up scientific discovery,” said Timothy Duong, director
of magnetic resonance research at Yerkes and associate professor of neurology. “Improving
network resources will definitely have a big impact on whatever
we do.”
