Abstract

A local application streaming proxy can create a virtual image of storage media, which allows cloud operators to rapidly deliver applications, or deliver any operating system remotely, while providing better security, network utilization, low power requirements, and consistent performance for streamed applications and operating systems. A station using its WiFi/LAN provides QoS guarantees (or priority) for application streaming network communications to create a consistent user experience regardless of other application bandwidth utilization. “HTTP demand paging” is also possible.
