The Juniper Networks WXC application acceleration platforms provide distributed enterprises with a scalable approach to accelerating application delivery over the WAN. Based on the integrated WX Framework, which delivers all the elements needed to accelerate applications and optimize WAN performance, the WXC platforms help businesses improve application response times, maximize WAN investments, and control and prioritize key applications.The hard drives provide support for Network Sequence Caching, which dramatically speeds the transfer of large files by eliminating repetitive data sequences. The hard-drive storage supplies the capacity needed to store long data sequences for long periods of time, enabling up to 100-fold increases in WAN capacity. The WXC platforms constantly communicate, exchanging vital information such as topology, accessibility, and path-performance metrics. The WXC platforms also interoperate with the Juniper Networks WX application acceleration platforms. In addition, the WXC Stack pairs WXC 500 platforms with a WX 100 platform to extend support for Sequence Caching to 155 Mbps bandwidth levels.
