Cisco Wide Area Application Services (WAAS) Mobile extends Cisco WAAS Software application acceleration benefits to mobile employees who travel outside the branch office and to branch-office and mobile users who access applications hosted in public cloud environments. Acceleration of mobile VPN connections over the public Internet brings different technical challenges than those for corporate WAN and branch-office optimization.
Lower-quality network connection than the corporate WAN
Instead of dedicated branch-to-corporate- WAN leased lines, mobile users are using public Internet connections such as DSL, Wi-Fi, satellite, dial-up, cable, and cellular. These connections have less bandwidth, higher packet loss and latency, and additional challenges such as time-slicing delay in cellular environments.
Shared computing resources on PC or laptop
Shared computing resources on PC or laptop: in contrast to branch-office users, who can rely on a dedicated branch device to provide application acceleration, mobile users have to share laptop or PC computing resources and the TCP software stack with many other PC applications.
Support cost and manageability concerns
The open environment of a Microsoft Windows PC, in contrast to the controlled environment of an appliance, has a very different class of stability and interoperability requirements, with numerous applications running on the PC: a variety of operating systems, browser versions, endpoint security applications, and VPN client software and a wide range of business applications.
