Carlson Wagonlit

Travel firm Carlson Wagonlit has slashed its network traffic by a third after deploying WAN optimization and file sharing devices from Expand Networks across Asia and Australia.

The project is part of a broader strategy to streamline Carlson Wagonlit's branch office infrastructure, no mean feat when Australia alone is almost as big as Western Europe. "[The goal is] maintaining LAN-like performance whilst moving to WAN-delivered services," explained Daniel Oertli, Carlson Wagonlit's vice president of IT for Asia-Pacific, in an email to Byte and Switch.

The Sydney, Australia-based exec deployed three 6940 devices from Expand in his data center, and a total of five 6910 devices in branch offices across Australia, Singapore, Hong Kong, Thailand, and India. (See Expand Wakes Up to WAFS, Expand Intros WAFS, CIFS Acceleration, and Storage & Networks Converge.)

The idea behind WAN optimization and Wide Area File Services (WAFS) is that users can ease the strain on their corporate networks by hosting key applications and files in a central location as opposed to keeping multiple copies of applications and data in branch offices.

Carlson Wagonlit has already boosted its network performance, less than a year after deploying the devices. "Direct benefits include a 30 percent reduction in network traffic, thanks to compression," explains Oertli.
