Packet loss compensation method, system and equipment based on cloud network fusion technology

A packet loss compensation method based on a cloud network fusion technology comprises the following steps: establishing a TCP protocol optimization algorithm model, and executing TCP protocol optimization; and performing FEC intelligent forward error correction; wherein the step of executing the TCP protocol optimization further comprises the following steps: providing a sending-confirmation mechanism, and sending out an instruction which requires a receiver to feed back and confirm the reception while sending out each data packet by a TCP sender; detecting whether each data packet sent by the TCP sender receives feedback information confirmed to be received by the receiver or not; detecting whether a link packet loss state exists or not; wherein when the feedback information which is sent by the receiver and is used for confirming receiving is not received or the link packet loss state is detected to exist, the TCP sender resends the data packet until the feedback information which is confirmed by the recei
