Ciena Wins Mesh Deal
Ciena won the job early in the year, and the work was done during the summer. (See Verizon Picks Ciena for Atlantic Mesh.)
The size of the build-out isn't being disclosed, but it involves hefty 10-Gbit/s pipes connected via Ciena's CoreDirectors. "You can get the idea this is a major network," says Ihab Tarazi, Verizon Business's vice president of global network planning.
Verizon wanted more reliability crossing the pond. The Sonet ring structure wasn't enough, because the unlikely event of two ring cuts will paralyze that part of the network. "All of us have been affected by some catastrophic situation," Tarazi says of his carrier brethren.
To ease the paranoia, Verizon has set up a mesh with six possible paths, as oppose to the two paths (clockwise or counterclockwise) offered by a ring. Customers are now given a "linear" 10-Gbit/s pipe that fails over to one of the five alternatives, Tarazi says.
Tarazi hinted that CoreDirector is the likely choice for some upgrades to come, such as the creation of a seventh path for restoration, and the buildout of nodes in Amsterdam and Philadelphia. Tarazi adds: "We looked at a lot of vendors, and we do have other vendors for this type of application on domestic networks."
