In today’s distributed enterprise, applications such as Microsoft® SharePoint and Windows® File Sharing transmit an increasing number of files and data sets over Wide Area Networks (WANs), overburdening available WAN bandwidth. To make matters worse, these collaboration applications can retransmit entire files (rather than just incremental changes) multiple times. The result is an inefficient utilization of available bandwidth and an unnecessary increase in WAN traffic. IT often responds by expending budget on more bandwidth or enhanced services. Alternatively, WAN acceleration technology can resolve the problem by enabling more efficient utilization of the existing network bandwidth.
