Verizon Business said Wednesday it is delivering its first mesh design configuration across the trans-Atlantic portion of its global IP network.
The configuration, which is based on Ciena Corp.’s CoreDirector Multiservice Optical Switches, provides six paths for re-routing traffic, if needed, on three submarine cable network systems. The six-way mesh network design provides reliability for customer voice and data traffic crossing the Atlantic Ocean, Verizon said.
Each circuit is assigned a specific end-to-end path, and if a service interruption occurs, transport equipment switches to protection circuits and traffic is routed to the next best available path. Previously, protection was only available against a single failure in the network.
Ciena’s On-Center Service Layer Manager provides automatic mesh restoration and service management.
"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.
Due to the success of this meshed configuration, Verizon Business said it will expand the project to the terrestrial global IP network in both the United States and Europe in 2007.
