Detailed Description
A more complete and complete description of the preferred embodiments of the present invention is now provided in connection with the appended drawings.
As shown in fig. 2, a lossless traffic concatenation management method based on message buffering includes a message transceiving control unit, a message buffering unit, and a link detection unit.
As shown in fig. 1, a lossless traffic concatenation management method based on message buffering is implemented by the following steps:
1) and the user configures the link state detection mode of the link detection unit and configures the message buffering resource and the buffering mode of the message buffering unit.
2) And starting the link detection unit, continuously detecting whether the link state of the back-end analysis system works normally or not, and updating the link state.
3) The message receiving and sending control unit receives a service data message of a backbone network and extracts relevant control information of the service data message.
4) The message receiving and sending control unit stores the service data messages into the message buffer unit for buffering according to a certain organization rule.
5) The message receiving and sending control unit acquires the link state of the back-end analysis system.
6) And if the link of the back-end analysis system works normally, the message buffer unit sends the buffered service data message to the back-end analysis system.
7) And after the service data message is analyzed by the back-end analysis system, the service data message is sent to the backbone network through the message transceiving control unit.
8) And if the back-end analysis system link is not in normal work, the message buffer unit sends the buffered service data message to the backbone network.
9) And the link detection unit feeds back and updates the link state according to the message transceiving action of the message transceiving control unit.
10) The message buffering unit releases and recycles the message buffering resources which are sent to the backbone network.
As shown in fig. 2, the message transceiving control unit receives a message, extracts message control information, implements order-preserving buffering of the message according to an organization rule, selects a message transmission path according to a link state, performs order-preserving transmission of the message, receives the message processed by the back-end analysis system, and performs order-preserving transmission. When the link state is normal, the forwarding path of the message is (i) → ((r) → → sixthly), and when the link state is abnormal, the forwarding path of the message is (i) → seventy → sixthly.
The message buffer unit buffers the order-preserving messages according to a certain organization rule, and performs buffer resource management. When buffering the message, different organization rules may be used for buffering, for example, a timestamp of the message or a timestamp that has been hashed is used, and after the message is sent to the backbone network, the relevant message buffering resources are recycled and released.
The link detection unit continuously detects whether the back-end analysis system link works normally, receives action feedback of the message processing control unit and updates the link state. The link detection unit may be a detection mechanism independent of the back-end analysis system, such as a high-precision timer, and in a set timer time, if the message transceiving control unit does not receive a message sent by the back-end analysis system, the link is considered to be interrupted; or a detection mechanism for implementing link detection in combination with the back-end analysis system, for example, implementing link detection according to the heartbeat message of the back-end analysis system.
The above-described embodiment is only a specific embodiment of the present invention, and is not intended to limit the present invention in any way, and all other embodiments obtained by a person of ordinary skill in the art based on changes, modifications, substitutions or alterations of the technical solution of the present invention are within the scope of the present invention without any creative effort.
