The APAC WAN Optimization Controller (WOC) market witnessed good growth in 2011, as WOC demand remained strong among enterprises. Nonetheless, market growth was somewhat dampened by global economic uncertainties, which caused enterprises to be prudent and cautious towards IT spending. In many ways, the growing issues faced by WANs around application latency and network congestion justified the need for WOC adoption. This was further emphasized by the need for enterprises to deliver more equitable levels of network performance across WANs as they expanded rapidly in size and across borders.
