Applications Driving Ethernet

•Top Market Sectors• Healthcare, finance, education, government, media

•Principal Applications• Site-to-site access, server consolidation, business

continuity/ disaster recovery, software as a service (SaaS), service orientated architecture (SOA), Internet access, distributed imaging, distributed storage area networks, converged networking, virtualization, cloud computing

Migration Considerations

• Bandwidth growth as a triggering event avoid new legacy purchases

• Multiple p-p circuit aggregation Simplify, reduce costs and scale

• Convergence of separate Voice, Data lines on single Ethernet Simplify, reduce costs and scale

• Full network migration to support new Business/IT/application strategies Develop new platform for application growth

• Facilities relocation as a trigger

Case Study: Health Care

Virginia Mason Medical Center

Key Facts

• Situated in Seattle, USA with 10 branches and numerous clinics spread across hundreds of square miles.

• Ranked amongst top 5% in the nation based on health grades.

• Network is comprised of 5,000 nodes & phones, 4,000 desktop devices & 250 servers.

• Each patient’s scans need to be analyzed by multiple specialists located in different locations.

• Many cases require 1,000+ scans per patient, Film-based scanning is inefficient and costly.

• Required a solution to link mobile CT scanners to main clinic in real time.

Virginia Mason Medical Center

The Legacy WAN: • Based on satellite and multiple T1’s

Replacement Network Criteria: • High speed. Required 100mb+ connection to each remote

branch and clinic.

• Reliable – zero packet loss to ensure real-time transfer of large images to multiple clinics.

• Scalable – to support upgrade from 4-16-64 slice CT scans.

• Cost – VMMC is a non-profit organization.

Virginia Mason Medical Center

The Benefits VMCC can now provide a centralized diagnostics service.

• Real-time transfer and diagnosis of images whilst patient is still in the scanner.

• Centralized diagnostics service – multiple specialists based in different locations viewing identical image.

• Significantly reduces time and costs associated with patient diagnosis.

• Exceeded customer expectations.

• Very cost efficient.

The Solution• Ethernet Virtual Private Line (EVPL)

Case Study: Education

New York Law School

Key Facts

• Preeminent independent law school founded in 1891.

• Based in lower Manhattan – 8 blocks from ground zero.• Strict security access regulations for underground cable access.

• 3 sites:-• Main campus – currently a construction site.

• Temporary accommodation – across the street.

• Halls of residence – several blocks away.

• Needed a new WAN built within an “impossible timescale” and amidst construction chaos.

• Seamless transition from legacy network during vacation.

New York Law School

The Legacy WAN • Multiple T1 circuits.

• Wireless link between main building and temporary accommodation across the street.

Replacement Network Criteria • Scalable – to meet current + future bandwidth demands of new

applications such as IPTV & collaborative learning.

• High-speed Internet access.

• Provisioning & management.

• Seamless virtual LAN between main campus and HoR.

• Cost.

New York Law School

The Solution• Ethernet Virtual Private Line (EVPL)

The Benefits • Cost-effective bandwidth increments as required.

• Easier to maintain, support and scale.

• Secure V-LAN.

• Future proof foundation for new applications.
