Global Crossing has upgraded the terrestrial capacity of its Wavelength Service to 40 Gbps 
The new network performance SLAs cover “propagation delay” on wavelengths. Propagation delay is the round-trip time required for a signal to travel the distance between two Global Crossing points of presence. Global Crossing said these network performance SLAs are important to customers because they give them a measurable assurance that their business-critical data is delivered in a timely manner. They also raise the bar for industry practices, which do not typically offer SLAs for propagation delay on wavelength services.
In addition, Global Crossing now provides a diversity planning service to give customers the ability to assign alternate, redundant routes by wavelength. This enables customers to stipulate a specific route for wavelength circuits. It also provides assurances that routing will not be changed without a customer’s agreement and allows customers to create multiple diversity scenarios that include circuits provided by other service providers, as well as Global Crossing.
