Parameters
Table 19: /config/liveq parameters
config/livetcp
Description
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.
The /proc/net/hp-velocity/config/livetcp file provides the configuration parameters to customize the
acceleration settings. The following parameters are supported:
• LatencyThreshold: Activate LiveTCP latency mitigation once the specified delay threshold (in milliseconds) is exceeded.
• CongestionControl: 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.
• AccelerationFilters: 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.
• PersistentFilters: 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.
Read / Write
• Read: Enter the following to query the configuration parameters:
cat /proc/net/hp-velocity/config/livetcp
• Write: Any single value using a string with the format <parameter> = <value>.
