Description
Technical field
The present invention relates to network communication applications field, especially a kind of utilize to establish congestion control data list optimization TCP
The method and device of connection.
Background technology
Congestion control is to be responsible for control data transmission mechanism inside Transmission Control Protocol, packet loss, overtime treatment mechanism etc., whole
Congestion control plays the role of the service quality of TCP critical inside a Transmission Control Protocol.
TCP connection is established initial stage, the parameters of congestion control all can there are one default values, then in actual transmissions process
In constantly adjust the process for generally requiring an adjustment so that transmission quality and stability are optimal effect here, so TCP
The initial stage of foundation is connected to not best laser propagation effect can not reached at once, needs etc. just to reach most when being adjusted to optimal value
Good transmission quality, and in view of the link-quality of different TCP connections is all different, so the parameter of congestion control can only be needle
One connection cannot be shared, under default situations, each newly-established connection is required for being calculated according to actual transmissions situation, together
When, when TCP connection interruption has been destroyed then congestion control data and can also be deleted, then after thering is the same Target IP to establish TCP connection, gather around
Plug data will recalculate, and for the same Target IP, can not quickly establish high efficiency of transmission channel.
Invention content
To solve the above problems, it is an object of the invention to by establishing congestion control data list in server end, deposit
The congestion control data for storing up the same Target IP directly invoke upper primary congestion control number when the IP resettles TCP connection
According to.
Technical solution is used by the present invention solves the problems, such as it：
A method of optimizing TCP connection using congestion control data list, includes the following steps：
The corresponding congestion control number of the TCP connection newly received is searched in the congestion control data list at current service end
According to；
If finding, the congestion control data indirect assignment of gained will be searched to the congestion control data of current TCP connection；
Otherwise, the corresponding congestion control data of current TCP connection are calculated, and the congestion control data are saved in the congestion control of server-side
Data list processed.
Further, when current service termination receives newly-established TCP connection, while the source IP of current TCP connection is obtained
Address.
Further, the congestion control data list stores the TCP connection using the source IP address of TCP connection as key assignments
Congestion control data.
Further, the key assignments of congestion data control list is searched using the source IP address of current TCP connection as keyword.
Further, IP address and its port numbers can also be used as key assignments, i.e., when current service termination receives new foundation
TCP connection when, while obtaining the source IP address and port numbers of current TCP connection.
Further, using the source IP address of TCP connection and port numbers as key assignments, storage should for the congestion control data list
The congestion control data of TCP connection.
Further, congestion data control list is searched as keyword using the source IP address of current TCP connection and port numbers
Key assignments.
Further, in the memory at the congestion control data list storage and current service end.
Further, when the congestion control data variation of TCP connection, corresponding data in congestion control data list are updated
Record, until TCP connection is closed.
A kind of device optimizing TCP connection using congestion control data list, including
Searching unit, for searching the TCP connection pair newly received in the congestion control data list at current service end
The congestion control data answered；
Processing unit, the lookup result for handling the searching unit will search the congestion control of gained if finding
Otherwise the congestion control data of data indirect assignment to current TCP connection calculate the corresponding congestion control number of current TCP connection
According to, and the congestion control data are saved in the congestion control data list of server-side.
Further, the searching unit is when receiving newly-established TCP connection, while obtaining the source of current TCP connection
IP address, or obtain the source IP address and port numbers of current TCP connection.
Further, the searching unit is using the source IP address of current TCP connection or source IP address and port numbers as keyword
Search congestion data control list.
Further, the processing unit updates congestion control data list in the congestion control data variation of TCP connection
In corresponding data record, until TCP connection close.
The beneficial effects of the invention are as follows：The above method and device are only congestion control data using congestion control data list
It stands on TCP connection to save, when finding to have identical TCP connection, just be obtained from previously stored congestion control data
Corresponding value is taken, the congestion control data inside indirect assignment to TCP connection avoid the TCP for coming from the same source
The congestion control data of connection, which are repeated several times, to be calculated, and the congestion calculated can be used when so that TCP connection is established at the beginning
Control data are transmitted control, promote TCP transmission efficiency, reduce the TCP congestion control calculated loads of repetition.

Specific implementation mode
Referring to Fig.1, a method of optimizing TCP connection using congestion control data list, first as the present invention
Embodiment includes the following steps：
The corresponding congestion control number of the TCP connection newly received is searched in the congestion control data list at current service end
According to；
If finding, the congestion control data indirect assignment of gained will be searched to the congestion control data of current TCP connection；
Otherwise, the corresponding congestion control data of current TCP connection are calculated, and the congestion control data are saved in the congestion control of server-side
Data list processed.
