Global Crossing has upgraded the terrestrial capacity of its Wavelength Service to 40 Gbps 
and begun offering new benchmark-setting network performance service level agreements (SLAs) and a new route diversity planning service. The capacity upgrade, which is being implemented on terrestrial routes in North America, Europe and the UK, is designed to deliver 40 Gbps services in both core and edge sites.
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.
