Technology Overview | HP Velocity
HP Velocity components
HP Velocity consists of the following components, which form an integrated system designed to improve overall QoE.
Figure 1: HP Velocity components
Policy Engine
• Matches application requirements
• Tunable through API or the Group Policy feature in Windows®
Network Profiler
• 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
QoS Controller
• Uses the current and trending network conditions provided by the Network Profiler to
intelligently activate and adjust the optimizers
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.
