Lossless flow series connection management method based on message buffering

Abstract

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 feedback of the message control unit and updating a link state. The method has the advantages of simple implementation method, lossless flow order preservation, high reliability and the like.

Description

technical field [0001] The invention relates to a network traffic serial connection management method, in particular to a message buffer-based lossless traffic serial connection management method, which belongs to the technical field of network serial connection. Background technique [0002] With the continuous development of modern network technology, network monitoring and analysis is an important part of maintaining the normal operation of the network. In the service scenario of network monitoring and analysis, the monitoring and analysis equipment is usually connected in series in the network system. In actual work, if the analysis system of the monitoring and analysis equipment fails, the analysis system is difficult to restore to normal in a short time, and sometimes even occurs The unrecoverable phenomenon causes the loss of business traffic, and once the analysis system cannot be recovered, the entire network will be interrupted. This kind of failure is unacceptable...

Problems solved by technology

In the service scenario of network monitoring and analysis, the monitoring and analysis equipment is usually connected in series in the network system. In actual work, if the analysis system of the monitoring and analysis equipment fails, the analysis system is difficult to restore to normal in a short time, and sometimes even occurs The unrecoverable phenomenon causes the loss of business traffic. At the same time, once the analysis system cannot be recovered, the entire network will be interrupted. This kind of failure is unacceptable

In the background technology, at present, the protection of monitoring and analysis equipment generally adopts serial optical protection equipment, but because the message analysis system in the monitoring and analysis equipment is relatively complicated and prone to failure, the existing serial optical protection equipment cannot realize Lossless protection of traffic
