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 = .
