Lossless flow series connection management method based on message buffering

The invention discloses a lossless flow series connection management method based on message buffering. The main technical characteristics are as follows: a message receiving and transmitting controlunit, a message buffer unit, and a link detection unit are included; the message receiving and transmitting control unit receives the message, extracts message control information, implements order-preserving buffering of the message according to an organization rule, selects and saves a message sending path according to the link state and sends the message a sequence-preserving manner, receives amessage processed by a rear end analysis system and sends the message a sequence-preserving manner; the message buffer unit is used for buffering the sequence-preserving messages according to a certain organization rule, performing buffer resource management, and the link detection unit is used for continuously detecting whether a link of the rear-end analysis system works normally or not, receiving and processing action
