Problems solved by technology

Generally, a separate Tap splitter is used to mirror and copy the data packets from the network equipment. Equipment failure will cause the interruption of the data source and make it unavailable.
Multiple packet processors generally only receive data from the Tap splitter, and have no connection with each other, so there is no mechanism for detecting faults and automatically switching packet processing
At the same time, the historical data packets stored by each data processor are also independent of each other, so that once the data packet processor fails, the stored historical data will not be available

Embodiment 1

[0049] According to the present invention, a high-availability system for bypass traffic processing is provided, including:

[0050] Module M1: The data packet gateway cluster receives network data packets from multiple Tap splitters;

[0051] Module M2: The main data packet gateway in the data packet gateway cluster partitions the network data packets, and sends each partition traffic to the main partition processing inside the corresponding data packet processor in the data packet processor cluster according to the partition information in the traffic device;

[0052] Module M3: The main partition processor processes the data packet traffic and stores the result data, and synchronously sends the result data to the standby partition processor located in the same partition inside other data packet processors;

[0053] Module M4: the standby partition processor backs up and stores the result data.

[0054] Specifically, it also includes: the data packet gateway cluster receiv...

Embodiment 2

[0079] Embodiment 2 is a preferred example of embodiment 1

[0080] The invention extends the working mode of using a single server to complete bypass flow collection and processing in the existing system to clusters to achieve high availability and performance scalability.

[0081] A loop mutual standby high-availability system that bypasses traffic processing bypasses network traffic to a data packet gateway cluster, and the data packet gateway cluster then copies and sends the network traffic to the data packet processing cluster.

[0082] In a cluster of packet gateways, the primary gateway is always responsible for sending packets. The standby gateway is responsible for sensing the state of the primary gateway.

[0083] The master gateway partitions the packets, with each partition preassigned to a set of packet processors in the packet processor cluster. The master gateway sends partition traffic only to those packet processors in the set that contain the master partit...

Abstract

The invention provides a cyclic mutual-backup high-availability system for bypass flow processing. According to a module M1, a data packet gateway cluster receives network data packets from a plurality of Tap optical splitters; according to a module M2, a main data packet gateway in the data packet gateway cluster partitions the network data packets, and according to partition information in the traffic, the traffic of each partition is sent to a main partition processor in a corresponding data packet processor in the data packet processor cluster; according to a module M3, the main partition processor processes data packet flow storage result data and synchronously sends the result data to standby partition processors located in the same partitions in other data packet processors; and a module M4: the standby partition processor backs up and stores the result data. According to the invention, the data source sending system and the data processing system are clustered, automatic failover of the processing stream and backup of historical data are realized, and high availability is integrally realized.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a high-availability system with loop mutual backup for bypass traffic processing. Background technique [0002] Bypass traffic processing refers to the mirror copying of business network traffic to the processing system. Through the capture, decoding, filtering, statistics, correlation and other processing of data packets, valuable information for monitoring business status is obtained. [0003] Bypass traffic processing often requires 7x24 hours of stable operation to achieve the purpose of monitoring business systems. Traditional bypass traffic processing lacks a high-availability design. Generally, a separate Tap splitter is used to mirror and copy the data packets from the network equipment. Equipment failure will cause the data source to be interrupted and unavailable. Generally, multiple data packet processors only receive data from the Tap splitter...
