(Panabit is a 7-layer flow control engine. The full name of the software copyright registration certificate is: network application layer flow control monitoring and management engine software panabit[panabit for short]. Panabit is a software system based on the intelx86 platform and positioned at the device level of flow control. Its research and development background is in the Internet application environment where P2P applications are popular. It is dedicated to the identification and control of P2P applications, often referred to as P2P flow control. It is a new generation of application layer QoS system. It needs to be installed in the independent intelx86 hardware and can be used normally when connected in series at the network outlet. To be more specific, panabit is based on flow analysis and application layer bandwidth management. It can be understood that traditional bandwidth management upgrades application layer bandwidth management. Panabit helps the broadband network manage the bandwidth of the application layer, but does not do content level analysis and restoration, that is, non behavior control and audit products. It is a well-known professional pure flow control system.)
