HP Velocity overview
HP Velocity is a Quality of Service (QoS) system that improves overall Quality of Experience
(QoE) for real-time network applications.
Streaming real-time applications over data networks will often suffer from packet loss and
transmission latency; this results in stop-and-go behavior, loss of interactivity, and an overall
reduction of an application's throughput. Ultimately, application users are likely to find
themselves dissatisfied with the experience.
HP Velocity easily integrates with existing systems to improve a streaming application's QoE
by addressing the underlying problems found in today's networks: packet loss, transmission
latency, and jitter.
Automatic discovery, session establishment, and session management are performed by HP
Velocity-enabled endpoints.
HP Velocity continuously monitors end-to-end network conditions to select the most
appropriate data delivery mechanism. Packet loss is automatically reduced and transmission
latency is minimized, thereby improving an application's QoE and throughput.
NOTE: HP Velocity only accelerates streams between HP thin clients and HP
Velocity-enabled virtual desktops or terminal services servers.

HP Velocity overview
Benefits of HP Velocity
Adaptive
HP Velocity continuously monitors end-to-end network conditions
network analysis for individual data streams, providing adaptive optimizations and
data stream acceleration.
Packet loss
protection
HP Velocity protects against packet loss, which is key to improving
an application's QoE. Even in small amounts, packet loss will
reduce application throughput, degrade or halt streaming
applications, and introduce lag for interactive applications.
Congestion
detection
HP Velocity automatically detects network congestion and adjusts
the amount of redundancy, thus maximizing QoE over data
networks.
WiFi acceleration HP Velocity automatically reduces latency and transmission times
for wireless networks and minimizes protocol overhead, resulting in
improved QoE for WiFi applications.
Seamless
integration
HP Velocity is a transparent, “plug and play” solution, which
provides QoE benefits to all applications and users.
Lightweight
HP Velocity is delivered as a lightweight implementation, which
achieves QoE benefits while keeping system resource utilization to
a minimum.

Starting the HP Velocity System Tray Application
Starting the HP Velocity System Tray Application
The HP Velocity System Tray Application controls the operational mode of HP Velocity. It
automatically launches on system startup. However, it may also be launched by performing
the following steps.
To start the HP Velocity System Tray Application:
1. Go to the Windows Start menu.
2. Go to HP Velocity > HP Velocity Tray Application.
3. Select HP Velocity System Tray Application as shown in Figure 1 below.
Figure 1. Windows Start Menu showing the HP Velocity System Tray application
When HP Velocity is running on an HP thin client, virtual desktop, or a terminal server, an icon
appears in the Windows System Tray, as shown in Figure 2 below. The icon color will change
based on the current operational mode of HP Velocity.

Identifying and setting HP Velocity operational modes
Identifying and setting HP Velocity operational modes
The HP Velocity System Tray Application icon is displayed in one of four colors that
correspond to different HP Velocity operational modes.
The following table describes the icon colors, operational modes, and their behaviors.
Icon
Color
Mode
Description
Green
Active
HP Velocity is actively accelerating one or more
streams.
Blue
Active
HP Velocity is active but no accelerated streams
have been established.
Orange Monitoring
HP Velocity is profiling present and trending network
conditions. In this mode HP Velocity does not
accelerate streams.
Gray
HP Velocity is disabled.
Disabled
Setting HP Velocity mode of operation
Once the HP Velocity System Tray Application is running, select the desired HP Velocity mode
of operation using the slider, as shown in Figure 3 below.
An administrator should only change the HP Velocity mode of operation:
• During troubleshooting to disable HP Velocity
• After troubleshooting to re-enable HP Velocity
• As directed by HP support

Displaying accelerated or monitored stream count
To set the HP Velocity System Tray operational mode:
1. Select the icon in the Windows System Tray.
2. In the resulting dialog box, select the slider control shown in Figure 3 below.
3. Move the slider control to the new mode.

NOTE: To change the HP Velocity mode of operation, administrator
privileges are required.
Displaying accelerated or monitored stream count
Position the cursor over the HP Velocity icon to display a tool tip with the number of active
streams.
Displaying HP Velocity thin client information
To obtain the version of HP Velocity on a thin client:
1. Right-click the HP Velocity System Tray icon.
2. Select About.
NOTE: This is the HP Velocity release number. It is not the HP thin client
image release number.
