WAN Optimization (WAN OP) products seek to accelerate a broad range of applications accessed by distributed enterprise users. They work by eliminating redundant transmissions, staging data in local caches, compressing and prioritizing data, and streamlining chatty protocols such as CIFS. WAN OP also helps avoid packet delivery issues including the latency common in WAN environments (e.g. MPLS and Internet VPNs). WAN OP enables organizations to improve overall application performance and allow for geographical consolidation of data and applications.
