Specific embodiment
The present invention gives a kind of flow stores the method and system of quick indexing, in order that those skilled in the art more fully understand the technical scheme in the embodiment of the present invention, and it is understandable the above objects, features and advantages of the present invention is become apparent from, below in conjunction with the accompanying drawings technical scheme in the present invention is described in further detail：
Present invention firstly provides a kind of method that flow stores quick indexing, as shown in figure 1, including：
S101 captures flow；
Stream in Transmission Control Protocol and udp protocol belonging to each message and/or session in S102 sign outflows；
S103 is directed to stream and/or session establishment incremental index number and sets up stream and/or session information structure；
One call number being made up of timestamp and incremented sequence number is generated to the stream belonging to first message finding in flow and/or session；
The stream information structure includes call number, five-tuple, initial time, end time, up-downgoing message number, byte number；
The session information structure includes call number, initial time, end time, up-downgoing message number, byte number, next session call number, storage location；
Information in stream and/or session is stored by S104 according to the call number size order of stream and/or session；
Information in stream and/or session is stored in stream file and/or session file in the way of structural array according to fixed size, and the storage location of stream and/or the information in session in stream file and/or session file is stored by the ascending order of call number, after the byte number stored in stream file and/or session file reaches the scope of user preset, automatically by follow-up stream and/or information Store in session in next stream file and/or session file, call number of the filename of stream file and/or session file comprising stream minimum in file and/or session, by filename, in file, stream and/or the relation between session and call number are saved in independent index file；
Based on Information Extracting strategy，When original flow information in session is stored，By multiple similar original flow informations according to the time numerical value for extracting，Ascending sequential storage is in same storage file,The entitled incremental numerical value of N of storage file，During storage，A header structure is added for each original flow information，Call number of the header structure comprising the session belonging to original flow information、The positional information of original flow message length original flow information similar with the next one，After storage，Record deviation post O of the original flow information in storage file，Storage file name N and deviation post O composition positional information structures L，If original flow information is first original flow information of affiliated session，In the session information structure that then positional information structure L is saved in belonging to original flow information，The header structure of a upper original flow information of current original flow information in session is searched otherwise，Positional information structure L is saved in the header structure of a upper original flow information，After the byte number stored in storage file reaches the scope of user preset，Automatically by follow-up original flow information Store in next storage file;
Based on Information Extracting strategy，When also original in session is stored，By multiple similar time numerical value of the also original according to extraction，Ascending sequential storage is in same storage file，The entitled incremental numerical value of N 1 of storage file，During storage，A header structure is added for each also original，Call number of the header structure comprising the session belonging to also original、Reduction file size、Reduction file type and also original HASH value，After storage，Record also deviation post O1 of the original in storage file，Storage file name N1 and deviation post O1 composition positional information structures L1，Positional information structure L1 is saved in the session information structure belonging to also original and also original HASH value and positional information structure L1 will be stored in file HASH storehouses，In storage also original，Whether there is the HASH values when pre reduction file in judging file HASH storehouses，If there is no，Then store，Otherwise by file HASH storehouses when positional information structure L1 corresponding to pre reduction file is updated in the session information structure belonging to also original，After the byte number stored in storage file reaches the scope of user preset，Automatically follow-up also original is stored in next storage file;
S105 sets up the index with call number as major key；
It is that major key creates index that call number can be replaced with IP address or port or domain name or URL or file HASH values；
Information of the S106 according to needed for the call number of stream and/or session is retrieved；
Stream file and/or session file that the information in stream and/or session is located quickly are navigated to according to index file, position of the information in stream file and/or session file in stream and/or session is then quickly positioned according to the call number of stream and/or session.
Present invention also offers the system that a kind of flow stores quick indexing, as shown in Fig. 2 including：
Trapping module 201, for capturing flow；
Sign module 202, for indicating stream and/or session in outflow in Transmission Control Protocol and udp protocol belonging to each message；
First sets up module 203, for being directed to stream and/or session establishment incremental index number and setting up stream and/or session information structure；
Memory module 204, for the information in stream and/or session is stored according to the call number size order of stream and/or session；
Second sets up module 205, for setting up the index with call number as major key；
Retrieval module 206, for the information needed for being retrieved according to the call number of stream and/or session.
In sum, the present invention is first to capturing stream and/or session of the message in flow according to belonging to Transmission Control Protocol and udp protocol are indicated, and for stream and/or session establishment incremental index number and stream and/or session information structure, information in stream and/or session is stored according to the call number size order of stream and/or session, according to the information with call number as needed for the indexed search of major key goes out.In traditional method, large storage capacity and quick-searching can only meet first, and the present invention can consume it is relatively low compared with low-resource and hardware version in the case of, meet the requirement of bulk information amount of storage, stream and/or session quick-searching requirement, and many condition be combined retrieval data on flows requirement.
