HP Velocity functional overview
Operational modes
HP Velocity protects and optimizes data flows between HP thin clients and HP Velocityenabled virtual desktops or terminal services servers. It provides three operational modes:
Protect, Monitor, and Off.
Protect mode
Protect mode is the default and recommended operational mode. In this mode, HP Velocity
provides session establishment, HP Velocity-protected flow statistics, packet loss protection,
WiFi optimization, and latency mitigation.
Monitor mode
In Monitor mode, HP Velocity monitors for packet loss and continuously profiles the end-toend network conditions over established flows. This mode disables all HP Velocity network
optimizers and is useful for acquiring baseline network characteristics.
Off mode
In Off mode, HP Velocity passes all network flows transparently and does not perform any
monitoring or optimization.
HP Velocity Server Side Deployment Guide8
HP Velocity functional overviewEstablishing a connection
Establishing a connection
An HP Velocity-protected connection is established over four steps (Figure 1):
• Initialization
• Beaconing
• Handshaking
• Protected state
Figure 1. Establishing a connection
Initialization
During initialization, HP Velocity-enabled endpoints start streaming data transparently. No
optimizations are performed.
HP Velocity Server Side Deployment Guide9
HP Velocity functional overviewEstablishing a connection
Beaconing
Once an HP Velocity-enabled endpoint detects that a bidirectional network path is available, it
periodically modifies packet headers (both IP and TCP) in a seamless way to advertise itself to
other HP Velocity-enabled endpoints (Figure 2).
IP headers can contain both IP ID-based beacons (using an option value of 0x420B) and IP
Option-based beacons (using an option value of 0x880477FB). TCP flows can use TCP
Option-based beacons (using an option value of 0x01 No-Operation and seven sets of End of
Option Lists 00000000000000).
Once an HP Velocity-enabled endpoint processes enough beacons on a network flow to
discover that another HP Velocity-enabled endpoint is at the other end, handshaking occurs.
NOTE: The use of TCP Option-based beacons for TCP flows and IP
Option-based beacons for UDP flows can be controlled through the
HP Velocity Policy Engine.
Figure 2. IPQ beaconing
Handshaking
An HP Velocity-enabled endpoint will initiate a three-way handshaking procedure with an
HP Velocity-enabled endpoint discovered during beaconing. Once the handshake is
completed, both HP Velocity-enabled endpoints enter the protected state.
Protected state
In the protected state, HP Velocity-enabled endpoints exchange information about current and
trending network conditions. This information is then used to intelligently activate and adjust
various optimizers.
HP Velocity Server Side Deployment Guide10
Deployment configurations
HP Velocity server-side deployments vary based on the virtualization architecture in use.
This chapter covers the following information:
• Deployments
• Deployment considerations
Deployments
HP Velocity is preinstalled on HP thin clients. Use the following table to determine where to
install HP Velocity on the server side.
Virtualization architecture
HP thin clients are directly connected to virtual
desktops or applications.
HP thin clients use a connection broker as a proxy to
access virtual desktops or applications.
The virtualization environment supports both direct
and proxied connections to virtual desktops and
applications.
HP thin clients connect to a terminal services server.

operating systems.

Virtualization architectures that allow an HP thin client to connect directly to a virtual desktop
must have the HP Velocity server installed on the virtual desktop. In this deployment, a

and B, as indicated by the color of the dotted lines.

Proxied
Virtualization architectures that require an HP thin client to access their virtual desktop via a
proxy service provided by a connection broker (such as VMware View Manager) must have an
HP Velocity server installed on the connection broker.
In Figure 4, thin clients A and B are connected to their virtual desktops via the connection
broker. An HP Velocity server is installed on the connection broker. This results in flows that
are protected by HP Velocity between the thin clients and the connection broker.

Direct and proxied
Some virtualization architectures allow both direct and proxied access to virtual desktops. In
this deployment, the HP Velocity server must be installed on:
• Virtual desktops that are accessed directly
• Connection brokers that provide a proxy service to access the virtual desktop
In Figure 5, thin client A connects to virtual desktop A through the connection broker, and thin
client B connects to virtual desktop B directly.

Terminal services
In a terminal services deployment, multiple HP thin clients are connected to a terminal
services server such as a Windows Server.
In this deployment, the HP Velocity server must be installed on the terminal services server
(Figure 6).
Figure 6. Example of a terminal services deployment
Protected flows - Multiple thin clients to terminal services server
HP Velocity supports a range of 16 to 1024 simultaneously protected flows.
The minimum supported protected flows are:
• 16 for HP thin clients
• 16 for virtual desktops
• 256 terminal services servers
HP Velocity defaults to the minimum supported simultaneous flows. If the default setting is
changed, the system must be rebooted for the change to take effect.
NOTE: HP Velocity server-to-server flows are only monitored, not protected. Only
flows between a server enabled with HP Velocity and an HP thin client are
protected.
NOTE: LiveTCP will provide latency mitigation for up to 32 simultaneous
protected flows.
About HP Velocity beacons
HP Velocity advertises its presence in a non-intrusive way by modifying IP and TCP headers
in compliance with International Engineering Task Force (IETF) standards.
If either IP or TCP Option beacons are enabled, HP Velocity will add up to 4 bytes of data to
the IP or TCP headers. This is in compliance with RFC 791 and RFC 793. Some applications
might not be compliant with RFC 791 or RFC 793, and as a result might not be able to process
IP or TCP Option beacons. If this occurs, disabling IP and/or TCP Option beacons should
resolve the issue.
For more information on configuring beacons, see the HP Velocity User Guide.
NOTE: HP Velocity beacons are:
IP Option - 0x880477FB (UDP Flows)
TCP Option - 0x010000000000000000 (TCP Flows)

HP Velocity management
This section covers the following information:
• HP Velocity Management Application modes
• Identifying the HP Velocity operational mode on Windows
• Setting the HP Velocity operational mode
HP Velocity Management Application modes
HP Velocity supports two Management Application display modes on Windows: Basic and
Advanced.
• Basic mode is launched by clicking the HP Velocity Management Application icon in the
taskbar. By default, the Basic mode is enabled for HP thin clients.
• Advanced mode provides a toolset for monitoring and troubleshooting HP Velocity-
protected flows and is launched by right-clicking the HP Velocity Management Application
icon in the taskbar (Figure 11) and selecting Management. By default, the Advanced mode
is enabled for server-side installations. For information, see “Using the Management
Application” on page 45.
Identifying the HP Velocity operational mode on Windows
The HP Velocity Management Application automatically launches on system startup and runs
in the background. The HP Velocity Management Application icon appears in the Windows
taskbar (Figure 11).
Figure 11. HP Velocity taskbar icon on Windows
The HP Velocity Management Application icon appears in one of four colors that correspond to
the HP Velocity operational modes (Tab le 1).
