Wide Area Application Services (WAAS) is a Cisco Systems technology that improves the performance of applications on a wide area network (WAN). WAAS combines Cisco's Wide Area File Services (WAFS) with WAN optimization inside of a router, accelerating TCP-based applications on a given network.
WAAS gives networking professionals a tool that is integrated with existing enterprise network architectures with minimal configuration steps. WAAS allows administers to manage and optimize networks to increasingly burdened by bandwidth-intensive applications like VoIP, video and Web applications.
