New Release of F5's WAN Optimization Product Offers Comprehensive CIFS Acceleration and Tops the Industry for Throughput

WANJet, the newest member of F5's market leading Application Delivery Networking solutions, provides superior acceleration of file access across the WAN for rapid return on investment

F5 Networks, Inc. (NASDAQ: FFIV), the global leader in Application Delivery Networking, today announced a new software release (version 4.0) of its WAN optimization product, WANJet® which now features CIFS acceleration. WANJet offers the highest levels of scalability in the industry - scaling up to 622 Mbps of throughput and up to 10,000 concurrent optimized connections on a single appliance. WANJet's CIFS capability significantly accelerates Windows file sharing, including remote access (across a WAN) of common Microsoft applications such as Word, Excel, and PowerPoint.

In addition, CIFS acceleration works seamlessly with F5's TDR™ (Transparent Data Reduction) technology to further boost acceleration on repeated CIFS data transfers. TDR is a F5 developed technology that provides high-speed application performance by reducing the amount of data transferred over a WAN link by up to 95%. TDR delivers significantly more bandwidth for applications and effectively expands WAN capacity above specified rates.

"As IT departments centralize servers to achieve regulatory compliance and lower costs, WAN optimization controllers (WOCs) must deliver LAN like application performance to remote clients. This must be done without requiring massive increases in WAN bandwidth charges" said Joe Skorupa, Research Director at Gartner, Inc. "Additionally, enterprises with large numbers of remote users require WOCs that scale to a very large number of optimized connections and very high throughput. This allows the network to scale without massive central site complexity."

"Navio's goal is to provide its customers with more flexibility, scalability and new forms of commerce through its world-class digital commerce services," said Will Lee, Director of Operations at Navio Systems. "F5's products including BIG-IP, FirePass and WANJet help enable us to achieve this key objective. The WANJet product has proven to be a solid return on investment for Navio and is a perfect complement to F5's family of Application Delivery Networking products. We look forward to the added performance and scale that the new WANJet release will deliver."

WANJet is now part of F5's leading Application Delivery Networking solution portfolio. F5's WAN optimization solution highlights include:

Greater productivity for Microsoft Windows file sharing - WANJet's CIFS acceleration enables customers to perform Windows file sharing (e.g. file download/upload, directory browsing and remote Microsoft file access) much more efficiently across a WAN.

Affords superior scale for high volume network environments - WANJet's scalability in terms of concurrent optimized connections (10,000 for WANJet 400) and TDR throughput (up to 400 Mbps) fulfills a critical requirement for organizations with a high volume network environment or numerous types of applications.

Easy-to-Use Interface - WANJet now features a powerful new user interface that is consistent with the BIG-IP product's interface. Its intuitive design increases the productivity of WAN administrators.

Trusted solution for comprehensive application acceleration - As an integral part of F5's Application Delivery Networking solution, WANJet is complemented by the high availability, security and scale that the F5 solution portfolio delivers. By deploying WANJet with F5's BIG-IP Local Traffic Manager, for example, customers can achieve virtually unlimited scalability, ideal for large enterprises and extremely high volume networks.
