Technology Overview | HP Velocity Quality of Experience with HP Velocity HP Velocity is a Quality of Service (QoS) software engine that improves the overall Quality of Experience (QoE) for real-time network applications. Real-time streaming applications delivered over data networks can be compromised by packet loss, transmission latency, and Wi-Fi congestion. This results in stop-and-go behavior, loss of interactivity, and an overall reduction in the throughput of an application. HP Velocity easily integrates with existing systems to protect application flows between HP thin clients and HP Velocity-enabled servers, including terminal services and virtual desktops hosted by VMware®, Citrix®, or Microsoft® hypervisors. It improves the QoE of a streaming application by addressing the underlying problems found in today's networks: packet loss, latency, and congestion. HP Velocity 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. By managing packet loss, Wi-Fi congestion, and the impact of network latency, HP Velocity improves QoS, providing a better experience for the end user. 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 to log files, making them available for analysis and troubleshooting. Benefits of HP Velocity Adaptive network analysis Monitoring Packet loss protection Latency mitigation Congestion detection Wi-Fi optimization Seamless integration Lightweight HP Velocity continuously monitors end-to-end network conditions for individual data flows, providing adaptive optimizations and application-flow protection. HP Velocity collects and reports an extensive set of statistics: • System information • Endpoint and per-flow network statistics: network-loss rates, corrected-loss rates, throughput, and latency HP Velocity provides packet-loss protection, which accelerates UDP application flows by reducing packet loss and the number of retransmissions. HP Velocity boosts application QoE in a high-latency environment. By actively adapting TCP, HP Velocity automatically calibrates congestion control parameters for each TCP flow, based on the conditions present in the network. HP Velocity automatically detects network congestion and adapts accordingly to maximize QoE. HP Velocity automatically reduces latency and transmission times for wireless networks and minimizes protocol overhead, resulting in improved QoE for Wi-Fi applications. HP Velocity is a transparent, plug-and-play solution that provides QoE benefits to applications and end users. HP Velocity is delivered as a lightweight implementation, which achieves QoE benefits while keeping system resource use to a minimum. 1
