Description
Technical field
The present invention relates to Internet technical field, in particular to a kind of TCP connection method, network delay determine method, dress
It sets and server.
Background technique
As network application and content are more and more abundant, network also increasingly congestion, but user is to network response speed
It is required that it is higher and higher, in order to which user's access speed is accelerated or optimized, can will usually be used by modes such as agencies
Family flowing of access guides environmentally being handled to acceleration or optimization.
In traditional agent way, agency is usually realized by the way that the request message of user is redirected forwarding
Function, specific implementation process may include: client and proxy server establishes connection, proxy server again with response server
Establish connection.In above-mentioned agent way, client is actually and proxy server establishes connection, therefore client is seen
Network delay is actually the time delay between client and proxy server, rather than network delay is (i.e. end to end for full link
Client is between response server).It is most of close to client network when due to proxy server deployment, client and
Network delay between proxy server is often below the network delay between proxy server and response server, then client
Network delay between proxy server may only have 1/the tens or even 1 percent of full link network time delay.That
, for needing the application using full link network delay data, such as need to carry out network test to server-side in client
The game application etc. of the real-time time delay of full link is obtained, after having used agency to be accelerated, the network delay actually obtained is
Client then can not correctly reflect the network delay of full link, may correspond to the network delay between proxy server
Data processing etc. causes misdirecting.
Therefore, a kind of Network Connection that client can be allowed accurately to detect full link network time delay is needed at present.
Summary of the invention
The application be designed to provide a kind of TCP connection method, network delay determines method, apparatus and server, energy
Enough improve the accuracy for the full link network connection time delay that client detects.
To achieve the above object, on the one hand the application provides a kind of TCP connection method, comprising: proxy server load is pre-
If kernel module, following network connection procedures are realized:
The first SYN message that request transmitting terminal is sent is monitored and received to the proxy server；
The proxy server and request responder establish connection；
The proxy server sends first SYN-ACK corresponding with the first SYN message to the request transmitting terminal
Message；
The proxy server receives the first ACK message that the request transmitting terminal is sent, so that the request transmitting terminal
It completes to be connected to the network with the proxy server.
To achieve the above object, on the other hand the application provides a kind of network connection time delay and determines method, comprising:
Transmitting terminal is requested to send the first SYN message to proxy server；
The request transmitting terminal receives first SYN- corresponding with the first SYN message of the proxy server feedback
ACK message, and the first ACK message is sent to the proxy server；Wherein, the first SYN-ACK message is the agency
It is issued when server and request responder completion establishment of connection；
The request transmitting terminal determines network delay according to the first SYN message and the first SYN-ACK message.
To achieve the above object, on the other hand the application also provides a kind of server, and the server is proxy server,
It include: request signal receiving unit, response server connection unit, response signal transmission unit and confirmation signal receiving unit；
Wherein,
The request signal receiving unit is used for and receives the first SYN message that request transmitting terminal is sent；
The response server connection unit, for establishing connection with request responder；
The response signal transmission unit is used for when the response server connection unit completes establishment of connection, to
The request transmitting terminal sends the first SYN-ACK message corresponding with the first SYN message；
The confirmation signal receiving unit, the first ACK message sent for receiving the request transmitting terminal；Described first
ACK message is corresponding with the first SYN-ACK message.
To achieve the above object, on the other hand the application also provides a kind of network delay determining device, comprising: request is sent
Unit, response confirmation unit and time-delay calculation unit；Wherein,
The request transmitting unit, for sending the first SYN message to proxy server；
The response confirmation unit, for receiving the corresponding with the first SYN message of the proxy server feedback
First SYN-ACK message, and the first ACK message is sent to the proxy server；The first SYN-ACK message is the generation
It is issued when reason server and the request responder completion establishment of connection；
The time-delay calculation unit, for determining network according to the first SYN message and the first SYN-ACK message
Time delay.
To achieve the above object, on the other hand the application also provides a kind of server, including memory and processor, described
Memory is for storing computer program, when the computer program is executed by the processor, realizes above method embodiment party
The method executed in case.
Therefore technical solution provided by the present application requests transmitting terminal to proxy server during TCP connection
SYN message is issued, proxy server immediately will not SYN-ACK message corresponding with the SYN message after receiving the SYN message
It is sent to the request transmitting terminal, but establishes connection with request responder, when the proxy server and the request respond
It holds after completing establishment of connection, then the SYN-ACK message is sent to the request transmitting terminal.Therefore, when request transmitting terminal
When receiving the SYN-ACK message that proxy server is sent, proxy server and request responder have been successfully established network
Connection, it is ensured that after requesting transmitting terminal and proxy server to establish connection, the request transmitting terminal with request responder it
Between can successfully realize that data are transmitted, improve request transmitting terminal and request the reliability of full link connection between responder.Together
When, when calculating network delay based on the connection method, it is ensured that the network delay being calculated is the network delay of full link,
The accuracy of network delay value is improved, can prevent the network delay being calculated from causing to the data processing etc. of application
Misdirecting improves the user experience of application.
