BlueCoat’s Mach5 (pictured) and PacketShaper appliances are WAN optimizers tailored for specific needs. Mach5 is targeted at businesses with consolidated IT, video, cloud or mixed IPv4 and IPv6 infrastructures. PacketShaper is aimed at businesses that depend on both network and web-based applications. Mach5 appliances combine protocol acceleration, compression, object and byte caching and QoS to help accelerate applications such as file access, email, web, storage replication and backup; and also support specialized live and on-demand video optimization for Adobe Flash, Windows Media, Silverlight and HTML5, among others. Mach5 also features cloud-caching engines to enable faster SaaS application access. BlueCoat recently went private under a $1.3 billion deal.
