As shown in Figure 1, Fig. 1 is a kind of determination method flow diagram of qualitative data shown according to an exemplary embodiment,
This method can be used in server, include the following steps：
Step 101, obtain user use Internet service when TCP (Transmission Control Protocol,
Transmission control protocol) data packet.
Terminal in the disclosure can be any intelligent terminal with function of surfing the Net, for example, can be specially mobile phone, flat
Plate computer, PDA (Personal Digital Assistant, personal digital assistant) etc..Wherein, terminal can pass through wireless office
Domain net couple in router, and pass through the server on router access public network.
In disclosure step, when user uses a certain Internet service, server end carries out packet capturing to TCP data packet,
It can carry out packet capturing using libpcap (Packet Capture library, packet capture function) library, can also use
Tcpdump programs carry out packet capturing.Since user may be longer using the time of a certain Internet service, thus it can capture to use and be somebody's turn to do
The TCP data packet in set period of time during item Internet service.
In the embodiment of the present disclosure, received server-side and the TCP data packet of transmission can be captured.In order to reduce server end
Performance consumption, can also TCP data packet or received server-side that only crawl server end is sent, i.e. user terminal sends out
The TCP data packet sent, due to the characteristic of Transmission Control Protocol, the TCP data packet that only crawl is received or sent does not interfere with the accurate of statistics
Property.
In the embodiment of the present disclosure, the TCP data packet that server end is received and/or sent in set period of time is taken out
Sample packet capturing or whole packet capturing can, but in the case of whole packet capturings, the accuracy of obtained qualitative data can higher.
Step 102 establishes TCP flow information based on the first packet in acquired TCP data packet.
In disclosure step, it is first determined first packet, it can be determined that the TCP marker bits SYN in the TCP data packet captured
Whether the position (synchronize, synchronous) is 1, is the head in the TCP data packet that is captured if it is 1 corresponding TCP data packet
Packet.Wherein it is possible to each TCP data packet be traversed according to the time sequencing of the TCP data packet captured, to determine first packet.
In the embodiment of the present disclosure, the information in the first packet extracted may include：Source IP (the Internet of TCP data packet
Protocol, Internet protocol) address, purpose IP address, source port, destination interface, user terminal starting Seq (Sequence
Number, sequence number) value, server end starting Seq values and initial time stamp (timestamp), be then based on and extracted
Information establishes TCP flow information.
Step 103, by TCP data packet of the transmission time after the transmission time of first packet and newly-built TCP flow information into
Row matching.
Step 104 determines that user uses the qualitative data of Internet service according to matching result.
In the embodiment of the present disclosure, server is by capturing TCP data packet and TCP data packet being analyzed and matched, just
It can determine that user is taken using the access of a certain Internet service, only need to carry out packet capturing on the server, be not necessarily to third
Method, system or client are supported, it will be able to fast and accurately obtain the qualitative data, cost is relatively low, has extensive be applicable in
Property.
As shown in Fig. 2, Fig. 2 is the determination method of another qualitative data of the disclosure shown according to an exemplary embodiment
Flow chart, above-mentioned steps 103 may include following step：
Step 201, the TCP data packet for that can match preceding four information in TCP flow information, judge the TCP data
Whether packet is first response ACK packet in acquired TCP data packet.
In the embodiment of the present disclosure, transmission time includes receiving time and sending time, and what it is for acquisition is server end hair
The case where TCP data packet sent, transmission time refers to sending time；For acquisition be received server-side TCP data
The case where packet, transmission time refer to receiving time.For the TCP data packet obtained in set period of time, with sending time
Or receiving time sequence is ranked up, first TCP data packet that be transmitted or being received is not necessarily first packet.
In the embodiment of the present disclosure, TCP data packet of the transmission time before the transmission time of first packet is abandoned, when by transmitting
Between matching process in the TCP data packet after the transmission time of first packet carries out the present embodiment with newly-built TCP flow information.For
Convenient for distinguishing, TCP data packet of the transmission time after first packet can be known as the first TCP data packet, if some first
TCP data packet cannot match preceding four information of TCP flow information, then it is assumed that it fails to match for the first TCP data packet, by this first
TCP data packet abandons；If certain first TCP data packet can at least match preceding four information in TCP flow information, then it is assumed that should
First TCP data packet successful match, continues following matching process to calculate qualitative data.
Wherein, qualitative data includes：Round-trip transmission time, Service Period sexual intercourse mutually take and TCP connection takes.
Step 202, when judging TCP data packet for first ACK packet, extract first ACK packet in timestamp.
In disclosure step, judge whether some first TCP data packet is that (ACKnowledgment is answered first ACK
Answer) packet process may include：When the first TCP data packet is the data packet that user terminal is sent, by the first TCP data packet
In user terminal starting Seq values subtract each other with 1, if met：Subtract each other the user terminal that the value obtained later is equal in TCP flow information to rise
Beginning seq value, then the first TCP data packet for meeting first condition are determined as first ACK packet.
When the first TCP data packet is the data packet that server end is sent, by the server in the first TCP data packet
End Seq values are subtracted each other with 1, if met：Subtract each other the server end starting seq values that the value obtained later is equal in TCP flow information, then
The the first TCP data packet for first being met the condition is determined as first ACK packet.
After first ACK packet is determined, the timestamp in first ACK packet is extracted.
Step 203 subtracts each other the timestamp extracted and initial time stamp, obtains past between user terminal and server end
Return transmission time.
The timestamp is subtracted into the initial time stamp in TCP flow information, obtains the RTT between user terminal and server end
(Round-trip Time, round-trip transmission time) time.
Step 301 judges that TCP data packet whether be send first of user terminal or server end includes payload
TCP data packet.
The deterministic process may include：Judge to indicate that this TCP data packet is included in the header packet information of the first TCP data packet
The data bit of data word joint number whether be 0, if not being 0, first the first TCP data packet for meeting the condition is determined
The TCP data packet for including payload for first.
In the embodiment of the present disclosure, due to being processed sequentially in time, thus first quilt to the first TCP data packet
It is judged as the TCP data packet that TCP data packet i.e. first comprising payload includes payload.
Step 302, in first for judging the TCP data packet and sending for user terminal or server end comprising payload
When TCP data packet, the timestamp in first TCP data packet comprising payload of extraction.
Step 303 subtracts each other the timestamp extracted and initial time stamp, obtains corresponding user terminal first packet time or clothes
It is engaged in the device end first packet time.
In disclosure step, for user terminal send first TCP data packet for including payload, by extraction when
Between stamp and the initial time stamp in TCP flow information subtract each other that obtain later is the user terminal first packet time, server end is sent
First TCP data packet for including payload, after the timestamp in the timestamp of extraction and TCP flow information is subtracted each other
To be the server end first packet time.
Wherein, the first packet time is the integral multiple of RTT times.
The first packet time that the RTT times and step 301-303 that above-mentioned steps 201-203 is obtained obtain may be collectively referred to as past
Return transmission time.
Service interaction keyword in step 401, extraction TCP data packet.
In disclosure step, service interaction keyword is extracted based on the full text of the first TCP data packet, which closes
Key word may include server, http etc..
Step 402 matches service interaction keyword with pre-set keyword.
Step 403, in successful match, extract TCP data packet in timestamp.
Step 404 subtracts each other the timestamp extracted and the initial time stamp in TCP flow information, obtains user terminal initiation
Ask taking for requested key node.
For example, user asks to access Sina website, this takes i.e., and initiating request to Sina website from user terminal is loaded into certain journey
The time of degree, the degree loaded depend on the keyword in data packet.
Step 501, for can match preceding four information in TCP flow information and for asking the TCP data of resource
Packet extracts user terminal Seq values or server end Seq values in TCP data packet.
The case where data packet for asking resource is directed in disclosure step.
Step 502 subtracts each other the user terminal Seq values extracted and the user terminal starting Seq values in TCP flow information, or will
The server end Seq values extracted are subtracted each other with the server end starting Seq values in TCP flow information, are obtained user terminal and are asked to right
The resource answered takes.
Wherein, requested resource size can be 1KB, 2KB, 1MB etc..
Calculated qualitative data may be collectively referred to as Service Period sexual intercourse in above-mentioned steps 401-404 and step 501-502
Mutually take.
Step 601 judges whether end FIN (Finish terminates) position in TCP data packet is 1.
Step 602, be judged as FIN for 1 when, extract the timestamp in the TCP data packet.
Step 603 subtracts each other the timestamp extracted and the initial time stamp in TCP flow information, obtains TCP connection consumption
When.
After all carrying out above-mentioned matching process to the first TCP data packet, obtained round-trip transmission time, Service Period
Interaction takes and TCP connection takes the TCP qualitative datas that i.e. user uses this Internet service.Also, step 603 it
Afterwards, TCP connection terminates,
Through the above steps, six kinds can be obtained and take (qualitative data), for a TCP data packet, it is possible to obtain
At least two take, these take and can not be superimposed, and each take can remove to weigh from some latitude quality of service, individually certain
A time-consuming or several take can combine for weighing quality of service.
The method that the disclosure provides only needs to carry out packet capturing on the server and can get user to use a certain interconnection
The access quality of network service is not necessarily to third party system or client suppor, has wide applicability, and can directly assess
The real service qualitative data of Internet service, accuracy are high.
As shown in figure 3, Fig. 3 is a kind of determination applied field of qualitative data of the disclosure shown according to an exemplary embodiment
Scape schematic diagram.In scene shown in Fig. 3, including：Server and smart mobile phone as terminal.
When user uses a certain Internet service, server obtains the TCP data packet from smart mobile phone, and according to institute
The receiving time sequence of the TCP data packet of acquisition judges whether SYN be 1 successively, and SYN are determined as 1 TCP data packet
First packet establishes TCP flow information based on the information in first packet.Then the TCP numbers by receiving time after the receiving time of first packet
It is matched successively with TCP flow information according to packet.For first ACK packet in TCP data packet, by the packet timestamp with
Initial time stamp in TCP flow information is subtracted each other, and the RTT times between mobile phone end and server end can be obtained.For
One TCP data packet for including payload, the timestamp in the packet is subtracted each other with the initial time stamp in TCP flow information can
Obtain the user terminal first packet time.The TCP numbers that can be matched with pre-set keyword for the keyword in TCP data packet
According to packet, the timestamp in the packet, which is subtracted each other with the initial time stamp in TCP flow information, can obtain user and initiate request to be asked
The key node asked takes.For the TCP data packet for asking resource, the user terminal Seq values in the packet are believed with TCP flow
User terminal starting Seq values in breath, which are subtracted each other, can obtain user's request taking to corresponding resource.For FIN be 1 TCP
Data packet, the timestamp in the packet, which is subtracted each other with the initial time stamp in TCP flow information, which can obtain TCP connection, takes.It is above-mentioned
RTT times, user terminal first packet time between the mobile phone end being calculated and server end, user initiate request to and are asked
It is all that user uses this that the time-consuming of the key node asked, user, which ask the time-consuming and TCP connection to corresponding resource to take,
The access of Internet service takes, i.e. qualitative data.
