BIG-IP^® WAN Optimization Module^™

Optimize and accelerate applications across the WAN

Application performance on the WAN is affected by a large number of factors that can’t be solved by adding bandwidth alone. The natural behavior of application protocols that were not designed for WAN conditions, application protocols that engage in excessive handshaking, and the serialization of the applications themselves can all limit performance.

BIG‑IP WAN Optimization Module (WOM) saves you time and money by speeding data transfers over the WAN and enabling traffic between BIG‑IP devices to be optimized, encrypted, and highly available.

BIG‑IP WOM accelerates file transfers, email, client-server applications, data replication, and more—resulting in reliable, fast performance for all users accessing applications across the WAN.

BIG-IP WAN Optimization Infrastructure

BIG-IP WOM is built natively on the F5 TMOS^® unified architecture, integrating application delivery with WAN optimization technologies. This enables traditional acceleration technologies like SSL offloading, compression, caching, and traffic prioritizing to combine with optimization technologies like symmetric adaptive compression and application quality of service, reducing complexity in your data center.

In addition, this integration enables BIG-IP WOM to make full use of the F5 iControl^® API and F5 iRules^™ scripting language capabilities, giving you unprecedented flexibility and control in scaling, managing, and optimizing your BIG-IP system.

iSessions

As the foundation for site-to-site communication, iSessions^™ secure and accelerate data traveling over the WAN. Any two BIG-IP devices can be deployed symmetrically to create a site-to-site secure connection to improve transfer rates, reduce bandwidth, and offload applications for more efficient WAN communication.

TCP Optimization

F5's TCP/IP stack is standards-based and contains hundreds of improvements that affect both WAN and LAN efficiencies. For low-speed WANs, symmetric TCP Express^™ detects client speed and estimates bandwidth to limit packet loss and recovery in the case of dropped packets. It improves transfer rates for all connecting client types and increases bandwidth efficiency across the WAN. TCP Express dynamically and automatically optimizes TCP window sizes and TCP congestion information for each connection symmetrically and asymmetrically (every client and every server), improving throughput in high loss networks.
