Verizon Business Enhances Trans-Atlantic Network

Basking Ridge, New Jersey (ots/PRNewswire) -

- Advanced 'Mesh' Configuration Enables Multinational Businesses
to Benefit From Unsurpassed Reliability

Verizon Business, one of the largest providers of IP global
communications services, has deployed a technologically advanced
network configuration on the trans-Atlantic portion of its global IP
network to provide more diverse routes to benefit large-business and
government customers.

This new configuration, called a mesh design, provides six diverse
paths for rerouting traffic, if needed, on three major submarine
cable network systems. The six-way mesh network design provides
unsurpassed reliability for customer voice and data traffic
traversing the Atlantic Ocean.

Previously, trans-Atlantic submarine networks used ring
configurations to provide redundant paths. However, that architecture
provides protection against only a single failure within any network
ring. In the event of a service interruption on two or more segments
of the same network system, no physical cable restoration is
available until a cable ship is deployed to make repairs.

"Although mesh designs have been used in the past on terrestrial
networks, we believe this is the most advanced design used for an
undersea cable network system," said Ihab Tarazi, vice president of
Verizon Business' global network planning. "As a result, we are able
to provide our large-business and government customers with
unsurpassed reliability for their mission-critical voice and data
traffic.

"This advanced design allows our customers to have their traffic
travel over pre-determined 'home' paths and special protection
circuits," Tarazi said.

Each customer circuit is assigned a specific end-to-end path. If
there is a service interruption, transport equipment switches to
protection circuits that are either pre-assigned or determined by the
system. Traffic is rerouted to the next best available path or paths.

Verizon Business has added multiple 10 gigabit paths to establish
more trans-Atlantic diversity and has deployed Ciena CoreDirector(R)
multiservice optical switching platforms at locations in both the
United States and Europe. Networked CoreDirectors continually
evaluate the health of the network and maximize its resiliency.

Verizon Business provides its customers with unparalleled
trans-Atlantic service reliability based on a unique combination of
customer-defined routing and protection paths over specific undersea
cables with automatic mesh restoration and real-time service
management using Ciena's ON-Center(R) Service Layer Manager.

In addition, for STM-1 (155 megabits per second) circuits and
above, Verizon offers options to customers for various levels of
protection. For example, the customer can specify the home route as
well as up to three prioritized protection paths while excluding
specific protection paths. If the customer specifies both a home
route and a dedicated protection route, restoration should occur
within 50 milliseconds (ms).

Due to the success of this new meshed network design
configuration, Verizon Business will expand this project to the
terrestrial global IP network in both the United States and Europe in
2007.
