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 of TCP flows in high-latency networks.
LiveTCP configuration settings (Table 9 on page 20
) specify the following parameters:
• Latency Threshold (ms)—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.
• Acceleration Filters—The port numbers that receive TCP flow acceleration is applied. Use a space-separated list of
ports or ranges; for example, 80 1750 1751 2003-2050.
• Persistent Filters—The port numbers that receive TCP flow acceleration and maintain the connection information for
reconnections. Use a space-separated list of ports or ranges; for example, 80 1750 1751 2003-2050.
