Architecture design firm dwp has adopted a WAN optimisation system from Silver Peak to accelerate file transfers and reduce infrastructure costs by 80 percent. The platform, Virtual Acceleration Open Architecture (VXOA), is now able to speed up transfers of AutoCAD-based files from days to minutes. According to dwp, it now takes only a few minutes to transfer 1 GB of data across the distributed enterprise, which includes 12 locations across Asia Pacific and the Middle East. There was an urgent need for dwp to lower its operating expenditure (OPEX) costs, which soared dramatically due to an increase in bandwidth costs necessitated by poor network connectivity between its data centre located in Bangkok and the various branch offices. In addition, link costs and latency were the highest between Bahrain and Bangkok.
