Technology Overview | HP Velocity HP Velocity components HP Velocity consists of the following components, which form an integrated system designed to improve overall QoE. Policy Engine Network Profiler QoS Controller Optimizers • Matches application requirements • Tunable through API or the Group Policy feature in Windows® • Profiles the network path between HP Velocity-enabled endpoints • Identifies the type of network connectivity (wired or wireless) and measures key network metrics (packet loss, latency, and bandwidth constraints) independently for each flow • Continually updates the QoS Controller with current end-to-end network conditions • Uses the current and trending network conditions provided by the Network Profiler to intelligently activate and adjust the optimizers • LiveQ: Provides end-to-end packet-loss protection to UDP application flows by automatically adapting the amount of added redundancy. For more information, see LiveQ on page 3. • LiveWiFi: Improves performance for congested Wi-Fi networks and increases the efficiency of TCP over Wi-Fi. LiveWiFi protects application flows by leveraging Wi-Fi standards to minimize latency, resulting in the prioritization of HP Velocity-protected flows. For more information, see LiveWiFi on page 4. • LiveTCP: Optimizes TCP throughput over all networks and provides latency mitigation for the RDP, HP Remote Graphics Software (RGS), PCoIP, VMware Blast, and Citrix ICA protocols. LiveTCP improves the throughput of streaming and remote desktop applications by modifying TCP flow control mechanisms to perform better in high-latency environments. For more information, see LiveTCP latency mitigation on page 6. Note: HP Remote Graphics Software (RGS) versions 6.0 and newer include HP Velocity as a built-in feature that is integrated into the HP RGS user interface on both the server side (RGS Sender) and client side (RGS Receiver). If you want to utilize HP Velocity solely for HP RGS, you do not need to install any standalone HP Velocity software components. For more information about using HP Velocity in HP RGS, see the User Guide for your version of HP RGS. HP RGS versions prior to 6.0 are not compatible with and do not include HP Velocity.
