Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only present invention a part, instead of all the embodiments.Based on the present invention
In embodiment, all other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, as the first aspect of the present invention, providing a kind of rapid data parsing side based on ten thousand megastream amounts
Method, which comprises
The data in the region audited will be needed to import in a mirror-image fashion after network convergence device converges and accept flow
The high-performance data that range is 0~10000M acquires network interface card, and the data include the session attribute of a variety of types；
By Filter module according to the good filtering rule of configured in advance to high-performance data acquire network interface card in data into
Row filtering, the session attribute that clearance security audit concern needs, and filtered data are transferred to cache module；
Load balancing is carried out to the data in cache module, data are referred to difference according to different session attributes
Stream in, realize the balanced of data and shunt；
Packet capturing and dissection process are carried out to data in stream by packet capturing parsing module, each packet capturing parsing module is corresponding
The processing of data packet in single stream；
Data after parsing are transferred to cluster server to be stored and integrated, and carry out data on administration interface
Classification is shown.
In above-described embodiment, the present invention first converges the area data flow for needing to audit by network convergence device,
Flow after convergence imports the high speed acquisition mouth of high-performance data acquisition network interface card, the high-performance data acquisition in a mirror-image fashion
The range of flow that network interface card is accepted is 0~10000M (10G), in the actual environment, since the data of inflow include a variety of types
Session attribute, such as HTTP, HTTPS, mail, multimedia, FTP, UDP, file etc., for security audit, not all class
The data of type require to pay close attention to, if the multi-medium data of UDP type is there is no need to pay close attention to, in order to filter unnecessary classification number
According to the present invention filtering rule good according to configured in advance by Filter module carries out the filtering of different business classification data, only
The useful data type of clearance security audit concern, can also be transferred to data by this measure to avoid invalid classification data
Process layer drags slow treatment effeciency to waste unnecessary process resource；Then the data in cache module load
Weighing apparatus, data are referred in different stream according to different session attributes, are realized the balanced of business datum and are shunted, after being
Continuous parallel, quick processing is prepared.It can be according to the quantity of the stream of configuration, starting pair after packet capturing parsing fusion program starting
The packet capturing parsing process answered, each process are responsible for corresponding to the processing of data packet in single stream；Finally by the data after parsing
It is transferred to cluster server to be stored and integrated, and carries out the classification displaying of data on administration interface.
The mechanism of the mating processing of multi-process is corresponded to, due to devising more stream so as to realize from serially one by one
Handle session data to it is concurrent a batch one batch processing session data transformation, data packet capturing, parsing processing speed obtained pole
Big to be promoted, for configuring 5 stream, test data processing speed is promoted to original 4 times.
Preferably, described that data progress packet capturing and dissection process in stream are specifically included by packet capturing parsing module:
Packet capturing parsing module receives data from corresponding stream by its matched data receiver API in time；It will connect
The data received carry out tcp group packet according to the sequence number parameter carried in message, are incorporated to tcp_connect queue preservation；When connecing
End message is received, then the complete session flow data that sequence, group packet is completed is subjected to dissection process；Data after parsing pass through
The mode of socket communication is transmitted to cluster server and is stored, further integrated, and is finally divided on administration interface
The displaying of class data is checked convenient for user, concludes and is analyzed.
Wherein, the end message is the end messages such as time_out, reset or fin.
Due to consideration that system operation will appear due to individual sessions do not have for a long time time_out, reset or
The end messages such as fin arrive, and the data dissection process movement of next step can not be triggered, to cause EMS memory occupation to rise violently, system
Fluctuation of service problem, devises timeout mechanism, and when a session is not received by end message within a preset time, active is inserted
Enter an end message as timeout packet, triggers current overtime conversation end, be transferred to the movement of next step dissection process, and then release
The memory source not discharged is occupied for a long time before putting, and both ensure that session data can be handled quickly, and had been also ensured system
Stable operation.
