Description
Technical field
The present invention relates to data network quality test field, more particularly to a kind of data network quality auto-dial testing method
And a kind of data network quality auto-dial testing system.
Background technology
Existing network e measurement technology carries out classification according to whether transmission message and can be divided into passive measurement technology and active testing
Technology.Passive measurement does not send message, but is chosen just in communication message as the case may be as bearing message, i.e., normal
Communication process in realize network measure, its principle be by capture bearing message information, passively realize network measure.
Active testing is actively to send bearing message, infers shadow of the network to these packet states according to the feedback message for returning
Ring, be derived from the status information of network.As passive measurement is difficult to understand performance end to end, it is also difficult to obtain global performance
View, and multi-party cooperation when measuring, is needed, therefore measurement range is limited.Additionally, passive measurement implementation complexity is higher, and
And need to check user data package, the secrecy and safety to user profile also brings certain threat.
Active testing technology is divided into Internet testing and application layer testing again, Internet testing by destination server,
The network equipment, pc client send ICMP(Internet Control Message Protocol, internet control message association
View)Message, so as to reach the purpose for understanding tested network.Application layer testing can be estimated to Network, by mesh
Mark server sends the analog message consistent with actual services message, to business in a network running status carry out true simulation with
Test.
Existing testing equipment is operated using manual type.When user adopts Internet testing, testing sets
It is standby send ICMP echo request data package to the network equipment or server according to fixed interval, and according to receiving
ICMP echo response response data packets carry out the statistics of the indexs such as packet loss, time delay.When user adopts application layer testing
When, testing equipment sends HTTP GET/POST request data package to server according to fixed interval, just for receiving
The round packet data recording of HTTP response responses receives the time, operating process all must user manually operate and complete.
However, during above-mentioned employing manual type carries out testing to Internet and application layer respectively, user needs
Understand the framework of whole network, and Internet or application layer group are carried out according to the failure condition for reporting to the network equipment or server
Survey.Function is automatically analyzed to failure as testing equipment lacks, after needing reporting fault, by user according to testing result, people
Work point analyses fault type.If user is unfamiliar with to fault type or the network to safeguarding lacks comprehensively understanding, then
Will be unable to during testing using suitable testing means, it is possible to causing trouble analyzes inaccurate problem occurring, nothing
Method reaches the purpose for carrying out accident analysis using testing equipment to network.
The content of the invention
Based on this, it is necessary to for the inaccurate problem of above-mentioned accident analysis, there is provided a kind of data network quality automatic poking
Survey method and system.
For achieving the above object, the present invention is adopted the following technical scheme that:
A kind of data network quality auto-dial testing method, comprises the following steps:
After the traffic order that testing server is issued is received, initiate to user terminal and destination application server respectively
Internet testing;
Judge whether Internet testing is successful;Carry out fault location if Internet testing is unsuccessful, and by positioning result
It is uploaded to the testing server;
If Internet testing success, dns resolution test is initiated to destination application server, and whether judge dns resolution
Success;DNS failure analysis result is uploaded if dns resolution is unsuccessful to the testing server;
If dns resolution success, initiate TCP handshake requests to destination application server, and judge TCP shake hands whether into
Work(;If TCP shake hands it is unsuccessful if upload TCP failure analysis results to the testing server;
If TCP shakes hands successfully, initiate HTTP connection requests to destination application server, and judge HTTP connections whether into
Work(;HTTP failure analysis result is uploaded to the testing server if HTTP connections are unsuccessful;Will if HTTP successful connections
Successful result is sent to the testing server.
A kind of data network quality auto-dial testing system, including testing equipment, the testing equipment include:
Starting module, for after the traffic order that testing server is issued is received, respectively to user terminal and target
Application server initiates Internet testing;
First judges and transmission module in result, for judging whether Internet testing is successful;If Internet testing is unsuccessful
Fault location is then carried out, and positioning result is uploaded to into the testing server;
Second judges and transmission module in result, for judging that the judged result with transmission module in result is yes described first
In the case of, dns resolution test is initiated to destination application server, and judge whether dns resolution is successful;If dns resolution not into
Work(then uploads DNS failure analysis result to the testing server;
3rd judges and transmission module in result, for judging that the judged result with transmission module in result is yes described second
In the case of, TCP handshake requests are initiated to destination application server, and judge whether TCP shakes hands successful;If TCP can not shake hands
Work(then uploads TCP failure analysis result to the testing server;
4th judges and transmission module in result, for judging that the judged result with transmission module in result is yes the described 3rd
In the case of, HTTP connection requests are initiated to destination application server, and judge whether HTTP connections are successful;If HTTP connects not
Successful then upload HTTP failure analysis result is to the testing server;Successful result is sent to into institute if HTTP successful connections
State testing server.
By above scheme as can be seen that a kind of data network quality auto-dial testing method and system of the present invention, establish
Fault type automatic decision flow process, by survey of shaking hands to the dns resolution test in Internet testing and application layer testing, TCP
Examination, the judgement of HTTP connecting tests, can know rapidly occurred fault type, realize testing equipment to fault type
Automatically analyze, reduce the workload of user, and it is also not high to the technical merit requirement of user, even if user is to testing equipment
Function be unfamiliar with or the network to safeguarding lacks comprehensively to understand and can also carry out auto-dial testing, so as to efficiently solve biography
System carries out the network measure institute inaccurate problem of caused accident analysis by manual type;Can also be dropped using this programme in addition
Low network O&M cost, improves the network operation efficiency of management.
