Strategy point storehouse 122, be the policy library at management and control center at the mirror image of local management and control node unit, storage be the monitoring strategies of a rule.Monitoring strategies is the matching template that the data flow of specific characteristic is carried out to specific operation.Monitoring strategies is mainly divided three classes: filtering policy, block strategy, replacement policy.Wherein, block strategy and refer to that management and control node unit blocks the stream information coupling of comparing according to blocking in strategy, in the time that the match is successful, illustrate to meet and block strategy, will abandon the follow-up data bag of current data packet and this data flow.Filtering policy refers to that management and control node unit, according to the coupling of comparing of the filtration stream information in filtering policy, in the time that the match is successful, illustrates and meets filtering policy, by the packet of deleting in coupling.Replacement policy refers to that management and control node unit, according to the coupling of comparing of the replacement stream information in replacement policy, in the time that the match is successful, illustrates and meets replacement policy, and the packet in coupling is replaced with to replacement stream information.
Wherein, first all-network data by management and control node unit will enter data input module 123, this data input module 123 is input to the data of Executive Module 125 for input data are carried out to preliminary treatment to optimize, and related data is stored in data memory module 126.
Concrete, data input module 123 need to carry out preliminary treatment to input data, and the Thread Count starting according to Executive Module 125, formulates the execution pretreatment unit corresponding with it to each thread.Each execution pretreatment unit is responsible for each packet and carries out parameter setting to simplify the operation of Executive Module 125, reduces system-level memory copying, to reach the target of single packet single duplication.In this preprocessing process, pretreatment unit needs the initial pointer alignment of setting data bag, and the initial pointer alignment of this packet is not only for storing the initial address of packet, and is in charge of and safeguards that one for storing the Buffer Pool of packet.The length of each initial pointer alignment is fixing in initial configuration, forms the operation of circular linked list minimizing system locking and de-locking, improves execution efficiency.Pretreatment unit is the space storage packet of each allocation of packets fixed length, the advantage of which is to reduce release and the application of memory space, can effectively utilize the memory page management of system simultaneously, reduce the generation of memory fragmentation, reduce the switching of memory pages, thereby improve the execution efficiency of whole managing and control system.Wherein, the executive capability of Executive Module 125 is determined by the size of the Buffer Pool of packet to a certain extent.
Wherein, all data of processing through Executive Module 125 finally all need by data outputting module 124, data outputting module 124 sent on network processing data by setting up buffer queue, and data outputting module stores relevant data and transmission record etc. in data memory module 126 into simultaneously.The buffer capacity of data outputting module 124 is relevant to the size of the Buffer Pool of packet, to be sent as possible principle, the packet of processing is sent from management and control node unit.
Executive Module 125, is the nucleus module of management and control node unit, has been responsible for the processing operation of all data, mainly comprises filter operation, break-in operation, replacement operation.This Executive Module 125 can be according to the optimization of being correlated with of the hardware of management and control node unit, to improve data-handling capacity.The processing operation of this Executive Module 125 also will be saved in data memory module 126.
Concrete, Executive Module 125 is nucleus modules of node, its execution efficiency will directly affect the overall performance of management and control node unit.In the present embodiment, Executive Module 125, for each execution CPU distributes fixing single execution thread to process data, can reduce like this system thread and switch the interruption producing, and reduces the handover operation in thread space, improves the service efficiency of CPU.Carry out data processing for each execution thread in the mode of chain type serial.In addition, in the present embodiment, three kinds of monitoring strategies can arrange different spreadabilities, and further the execution flow process of Executive Module 125 is optimized according to spreadability separately, for example: set and block tactful spreadability maximum, next is filtering policy, it is finally replacement policy, in the time blocking strategy and be performed, to directly skip filtering policy and replacement policy, in the time that filtering policy is performed, will directly skip replacement policy, and replacement policy just can exit after must executing all replacement policies.
For example: when monitoring strategies only comprises while blocking strategy, the handling process of Executive Module 125 comprises: packet buffer memory on the link of interception place, the packet of interception is compared and mated with the stream information that blocks blocking in strategy, in mating time, by other data packet discardings after the packet of the packet of interception and interception, in not mating time, other packets after the packet of the packet of interception and interception are let pass.
