HP Velocity functional overview

Real-time applications delivered over data networks can be compromised by packet loss and transmission latency. This results in stop-and-go behavior, loss of interactivity, and an overall reduction in the throughput of an application.

HP Velocity is a Quality of Service (QoS) software engine that integrates seamlessly and, when protecting application flows, enhances the user’s Quality of Experience (QoE) by managing packet loss, congestion, and the impact of network latency.

HP Velocity easily integrates with existing systems to provided either single-sided or bookend protection. It automatically ensures the best end-user QoE by optimizing the use of the underlying network to meet the requirements of bandwidth-intensive applications over wired and wireless, managed and unmanaged networks.

HP Velocity continuously monitors end-to-end network conditions to select the most appropriate data-delivery mechanism. Rich reporting capabilities enable HP Velocity to provide end-to-end visibility to key flow information. The system’s network monitoring and reporting tools capture in-depth statistics and make them accessible for further analysis and troubleshooting.

HP Velocity configuration

HP Velocity is installed with a default configuration suitable for most deployments. This section provides information about using the HP Velocity Policy Engine to create a custom HP Velocity configuration on a supported Windows platform and covers the following information:

HP Velocity Policy Engine

HP Velocity configuration settings

HP Velocity account privileges

Note:

For information about accessing a report that describes the current configuration, see

“Generating the HP Velocity Configuration Report” on page 30 . For information about specifying

configuration settings that apply only temporarily (i.e., until a system restart), see

“HP Velocity management” on page 23

.

HP Velocity Policy Engine

The HP Velocity Policy Engine uses Microsoft Group Policy, which provides centralized management and configuration of users and computers in a Windows Active Directory (AD) environment.

Group policy settings are contained in a group policy object (GPO), which can be used to centrally manage and propagate new settings for HP Velocity over an entire Windows AD domain.

To create a GPO, use the Group Policy Management Console (GPMC), which is available for download from the

Microsoft Download Center

web site. After the GPO is created, add the HP Velocity

Administrative Template to it (see

“Adding an HP Velocity Administrative Template to a GPO” on page 10 ).

Each HP Velocity Administrative Template consists of policies that allow administrators to create a

custom configuration for HP Velocity (see “Configuring HP Velocity using the Group Policy Object” on page 11 ). They also specify which registry keys are set when a custom configuration is created.

Adding an HP Velocity Administrative Template to a GPO

Note:

The HP Velocity Administrative Templates are included with the HP Velocity installation packages available at http://www.hp.com/support

.

1. Open the applicable Group Policy Editor:

• For local group policy administration, use gpedit.msc

.

• For domain group policy administration, use gpmc.msc

and select the applicable GPO.

2. Click Computer Configuration.

3. Right-click Administrative Templates, and click Add/Remove Templates.

4. Click Add.

5. Browse to and select hp_velocity_configuration_REL#-R#.adm

Policy Filter (Port & IP) settings

Global policy filters (

Table 5

) allow administrators to filter and optimize application flows on the basis of port number, destination IP address, or both. When multiple policy filters are configured, they are evaluated in a predefined order.

The Policy Filter (Port & IP) settings specify the following parameters:

• Transparent Ports TCP, UDP: The TCP and UDP port numbers whose application flows HP Velocity will not protect, but will instead pass on transparently.

• Special TCP, UDP Ports: The TCP and UDP port numbers to which HP Velocity will provide support for certain protocols (see

Table 6

).

• Whitelist TCP, UDP Ports: The TCP and UDP ports whose application flows HP Velocity will protect when the following criteria are met:

- The destination IP address for the application flow is not specified in the IP Blacklist filter.

- The destination IP address for the application flow is specified in the IP Whitelist filter.

• IP Address Blacklist: The destination IP addresses of application flows that HP Velocity will not protect, but will instead pass on transparently.

• IP Address Whitelist: The destination IP addresses of application flows that HP Velocity will protect.

Important:

When the IP Whitelist filter is configured, HP Velocity protects an application flow only if its destination IP address matches an address included in this filter.

Note:

If the IP Whitelist filter includes subnet destination IP addresses, the IP Blacklist filter can be used to filter IP addresses in that subnet whose application flows HP Velocity will not protect.

Figure 6: Policy Filters (Port & IP) settings

LiveQ Packet Loss Protection settings

LiveQ Packet Loss Protection applies a mathematical transformation to original input packets. The transformation outputs one or more segments for each original packet received as input. Each segment logically represents a portion of the input packet and might carry additional information, such as redundancy data. The number of logical segments used to represent an original packet varies based on current network-loss conditions.

Target Loss Rate policy filters can be used to specify the IP addresses and ports of application flows to which a specific level of packet loss protection is applied.

LiveQ Packet Loss Protection configuration settings (

Table 7

and Table 8 ) specify the following

parameters:

• Global Target Loss Rate: The Target Loss Rate (TLR) that HP Velocity will attempt to achieve for

HP Velocity-protected flows.

Note:

TLR refers to the amount of packet loss that an application can tolerate while still delivering an acceptable QoE. The recommended TLR for applications is 0.04%.

• Congestion Avoidance: Analyze network links to identify those with bandwidth constraints, and then automatically adjust packet-loss protection to accommodate the constraints.

• Bandwidth Control: The encoding level applied to HP Velocity-protected flows. HP Velocity constantly monitors network loss and automatically applies the protection mode required to reduce network loss to the default TLR. The protection mode used at any given time depends on the real-time loss measured in the network.

• Burst Loss Protection (BLP): Protect against correlated (sequential) loss in the network that can otherwise prevent HP Velocity from reconstructing source packets at the remote endpoint.

17

Administrator Guide for PCs | HP Velocity

Note:

The net effect of BLP is added resiliency against burst loss. Its success depends on the number of source packets that are encoded by HP Velocity and the sequential loss duration. BLP might degrade performance for highly latency-sensitive applications.

• BLP Buffer: The amount of packet buffering (in milliseconds) that HP Velocity can use when protecting against bursty or correlated loss.

• Target Loss Rate Policy Filters: The TLR that HP Velocity will attempt to achieve for all protected flows whose destination IP address, TCP port number, or UDP port number are included in this policy filter.

“Network Monitor graph” on page 26 ) to

verify whether the rate specified is being achieved.

• Disabled

• Enabled

Note: When Congestion Avoidance is enabled and bandwidth constraints are detected, the bandwidth and default TLR settings are overridden to ensure the best network performance possible.

• Dynamic: Maximize performance while minimizing the required bandwidth (recommended for environments where bandwidth is not constrained).

• Low: Cap the estimated HP Velocity protection overhead at or below 27% (recommended for environments where bandwidth is very constrained).

• Medium: Cap the estimated HP Velocity protection overhead at or below 40% (recommended for environments where bandwidth is moderately constrained).

• High: Maximize performance in environments where bandwidth is not constrained, but network loss is high. When

HP Velocity is at the far end, High mode uses aggressive encoding without first measuring the loss in the network.

Note: Higher encoding levels protect against greater network loss, but require more bandwidth.

LiveTCP Latency Mitigation settings

As HP Velocity observes the network and detects packet loss, the LiveTCP congestion control algorithm dynamically adapts to changing network conditions, boosting QoE in high-latency networks.

Note:

LiveTCP Latency Mitigation configuration settings are included only in the HP Velocity

Administrative Template.

LiveTCP Latency Mitigation settings (

Table 9

) specify the following parameters:

• Latency Threshold: Activate LiveTCP Latency Mitigation once the specified delay threshold (in milliseconds) is exceeded.

• Congestion Control: The level of congestion control required. LiveTCP adapts its algorithm to automatically provide congestion control that is optimized independently for each TCP flow (LAN, remote network, Wi-Fi) and the conditions in the network.

19

Administrator Guide for PCs | HP Velocity

• Advanced Congestion Detection: Apply advanced tuning that detects and reacts to packet loss.

• Peering Filters: The port numbers on HP Velocity-enabled endpoints to which the LiveTCP algorithm is applied to application flows.

• Non-Peering Filters: The port numbers for which the LiveTCP algorithm is applied to application flows being transported from an HP Velocity-enabled endpoint to a non-HP Velocity-enabled endpoint. The algorithm will not be applied to application flows being transported from the non-HP Velocity-enabled endpoint to the HP Velocity-enabled endpoint.

FAQs

This section provides information for the following scenarios:

All HP Velocity application flows are blocked

Protected flows are not established

TCP-based VPNs are not protected

All HP Velocity application flows are blocked

HP Velocity uses the IP ID value 0x420B and the IP option 0x880477FB in IP headers, and the TCP option 0x01000000 & 0x00000000 in TCP headers.

Intrusion Detection Systems (IDS) and firewall systems might require configuration to support

HP Velocity-enabled traffic so that devices will not block it. Consult your device manuals to configure these settings.

Protected flows are not established

Architectures that require devices to access servers via a proxy service provided by a connection broker (such as VMware View Manager) must have HP Velocity installed on the connection broker.

This ensures that protected flows are established for connections to a VMware desktop where HP

Velocity is installed.

TCP-based VPNs are not protected

HP Velocity does not provide protection for point-to-point connections for the Secure Socket

Tunneling Protocol (SSTP) VPN type.
