Global Crossing's 'Different' 40G Strategy

Global Crossing (Nasdaq: GLBC) says its new 40Gbit/s (gigabits per second) service in North America and Europe, using Infinera Corp. (Nasdaq: INFN) gear, will come with Service Level Agreements (SLAs) and a route-diversity program to enable those services to function more like existing Synchronous Optical Network (Sonet) services.

"We are trying to differentiate the product by adding more layers of SLA protection to give the customers the feel and the confidence that despite it being a wavelength service, it is highly reliable," says Mark Manioci, director of transport product management for Global Crossing.

Why this matters
Every major service provider is planning the transition from 10Gbit/s links that have been the industry standard to 100Gbit/s links for greater bandwidth. Some are including a stop at 40Gbit/s along the way.

Balancing the economics of what to deploy when is still a challenge -- one Heavy Reading analyst Sterling Perrin will be addressing on Feb. 8 in a free Webinar, Navigating the 40G/100G Market.

Here’s a quick look at Global Crossing's strategy:

Differentiation: By offering propagation delay and availability guarantees via SLAs, Global Crossing hopes to prove service reliability to enterprises that want faster links for financial trading, greater bandwidth for video and reliable service for connections between data centers for cloud offerings and more.

Route Diversity: The route diversity option -- which comes with a planning tool for enterprises -- is intended to convince enterprises that may be buying multiple 10Gbit/s circuits from different carriers to buy a 40Gbit/s from Global Crossing. "We will then guarantee them diverse routing of those circuits to offer the same level of protection," Manioci says.

The Challenge: Whatever service Global Crossing or any other service provider unveils, there is immediate pressure to make it available cheaply, and that adds to the pressure to get the technology right from the outset, Manioci says, and to avoid deploying anything that will require expensive endpoints.
