Specifically, the client device 200 may include a terminal device that directly receives a user operation, such as a smart phone, a computer, a tablet computer, and a smart television; the source station 300 includes a server providing an application service; the proxy server 100 includes a proxy device, which can be a server host or a routing device, for providing network transmission optimization for data requests issued by client devices.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a proxy server structure according to an embodiment of the present invention, as shown in fig. 2, a proxy server 100 includes a traffic identification module 110, a rule conversion module 120, and a detection module 130, and it should be noted that these modules are based on logic function division to clearly illustrate functions of the proxy server. In implementation, the functions of the modules can be implemented by executing the corresponding program codes.
Referring to fig. 3, fig. 3 is a flow chart of a transmission line probing method according to an embodiment of the invention. A specific implementation of the transmission line detection method according to the embodiment of the present invention will be described in detail below with reference to the drawings.
As shown in fig. 3, a transmission line probing method provided in an embodiment of the present invention, where the transmission line is used for transmitting a data request, specifically includes the following steps:
step 101: the application type and destination address to which the data request belongs are determined.
In implementation, the traffic identification module 110 in the proxy server may analyze the received data request to obtain a destination address of the data request, including a destination IP and a port, and may identify an application type to which the data packet belongs by using a deep inspection technology of a dpi (deep packet inspection) data packet, where the application type may be set according to an actual requirement, and may be classified into a game type, a video type, or another type; or specific to a particular application such as arcade, QQ, tremble, etc.
In implementation, the proxy server can identify the data request in real time and detect the corresponding transmission line when the data request is received; preferably, the proxy server may record the received data request, and periodically identify the recorded data request and detect the transmission line, so as to avoid the influence on the processing rate of the data request.
Step 102: and determining whether a corresponding detection conversion rule exists according to the application type and the destination address, if so, executing step 103, and if not, executing step 104.
In implementation, the proxy server is provided with a probe conversion rule table in advance. Probe transformation rules table as shown in table 1, the data quality transformation rules may include, but are not limited to: the method comprises the following steps of applying type, network segment information, a source station IP, a source station port, latest query time and a detection conversion rule, wherein the network segment information can be obtained based on the destination IP address statistics of a received data request; the source station IP and the source station port can comprise the IP and the port in the destination address obtained by analyzing the data request; the latest query time may comprise the time when the proxy server receives a data packet comprising the source station IP and the port; the probe translation rule may include probe address information.
TABLE 1 survey conversion rules Table
In implementation, after the proxy server obtains the application type and the destination address included in the data request, it may look up whether the corresponding probe conversion rule exists in the probe conversion rule table to determine whether the corresponding probe conversion rule exists.
Optionally, the rule converter 120 in the proxy server may first determine each IP network segment corresponding to the application type of the data request, and then determine whether there is a target IP network segment to which the destination address of the data request belongs from each IP network segment; if the data request exists, the corresponding detection conversion rule can be determined to exist, that is, the detection conversion rule corresponding to the target IP network segment is the detection conversion rule corresponding to the data request.
In implementation, after the rule converter of the proxy server determines the target IP network segment to which the destination address of the data request belongs through the above steps, the corresponding probe conversion rule may be obtained, and the probe address included in the probe conversion rule is determined to be the converted probe target, and the probe module 130 of the proxy server may obtain the quality data of each transmission line based on the converted probe target.
In implementation, the proxy server may record a detection result of the detection module, where the detection result includes quality data of each transmission line and latest detection time, and when an acquisition request of the quality data is received, a local record may be searched first to determine whether corresponding quality data exists, and if so, a difference between the latest detection time and a current time of the system may be referred to whether an effective period is exceeded or not to determine whether to directly use the quality data in the record as the quality data of each transmission line corresponding to the current detection target, and if the difference does not exceed the effective period, the quality data in the record may be directly acquired as the quality data of each transmission line corresponding to the detection target; if no corresponding record exists or the difference value exceeds the valid period, an access request can be generated based on the converted detection target and is respectively sent to the corresponding source station through each transmission line, and then the quality data corresponding to each transmission line is determined through the received response information of the source station, and the detection result is recorded at the same time. The quality data may include time delay, bandwidth, packet loss rate, cost, and the like.
For example, if the application type to which the data request belongs is determined to be GAME _ a, the destination address is 192.168.1.2, and the port is 2014, the target network segment can be determined to be 192.168.1.0/25, and the detection address 192.168.1.1 in the detection conversion rule is obtained; 2024 as a converted detection target. After the detection target is determined, whether available records exist locally or not can be inquired, if yes, corresponding quality data can be directly obtained from the records, and if not, the detection module is based on the detection target 192.168.1.1; 2024 generates access requests and sends them to the source station of 192.168.1.1 via each transmission line, and determines quality data of each transmission line based on the response of the source station.
In implementation, if the rule conversion module determines that there is no probe conversion rule corresponding to the data request or the probe conversion rule is empty, the probe module may directly perform probing on each transmission line based on the destination address in the data request to obtain quality data of each transmission line, and record the probing at the same time.
In implementation, the rule conversion module may record the application type, the destination address, and the query time to which the data request belongs, for example, in the above-mentioned probe rule conversion table, so as to update and perfect the probe rule conversion table.
In an implementation, the method for generating the probe conversion rule may include:
firstly, collecting destination addresses corresponding to each application type, and dividing according to IP network segments. The destination addresses corresponding to the application types can be collected through manual configuration and the record of the rule conversion module, and then the corresponding IP network segments are determined based on the collected destination IP.
Then, selecting a destination address in each IP network segment for detection, setting a detection address in a detection conversion rule corresponding to the IP network segment in the application type as the destination address when the server corresponding to the destination address is determined to respond normally, and determining that the corresponding detection rule is empty if the servers corresponding to all the destination addresses in the IP network segment respond abnormally. It should be noted that, in the embodiment of the present invention, whether the server responds normally may be determined based on whether the response information of the source station server can be received normally, specifically, if the response information of the source station server can be received normally, it indicates that the corresponding transmission line can perform data transmission normally, and at the same time, based on the time information of the request response, the network operator, the quality data of the transmission line may be determined Or the line delay does not exceed the threshold m, etc.
Optionally, the method for selecting the destination address in each IP network segment to perform detection may include preferentially selecting the destination address with the latest recording time.
Therefore, the transmission line detection method provided by the embodiment of the invention identifies the application type to which the data request belongs, and simultaneously obtains the detection conversion rule through the destination IP, so as to converge different detection requirements in the same network segment into a detection target, thereby reducing the detection number. Under the same application type, if the destination IPs belong to the same network segment, it means that the source station servers pointed by the destination IPs belong to the same operator and have similar geographical locations, that is, the probability of duplication or partial duplication of each transmission line from the proxy server to the source station is high, so that the quality of each transmission line of the converted detection target can directly correspond to the quality of each transmission line of the destination IP. Furthermore, the validity of the detection address in the detection conversion rule can be ensured by periodically updating the detection conversion rule, and meanwhile, the detection module can be triggered to acquire the latest quality data of each transmission line corresponding to the detection address through updating the detection address, so that the detection module can directly and quickly feed back the detection requirement in the valid period.
Based on the transmission line detection method, the embodiment of the invention also provides a routing strategy generation method. Referring to fig. 4, fig. 4 is a flowchart illustrating a method for generating a routing policy according to an embodiment of the present invention. The method can be applied to the proxy server. As shown in the figure, the routing policy generation method includes the steps of:
and S410, acquiring a data request.
In an implementation, the data request may include a data request for a business application initiated by the client device to the source station. The proxy server may obtain the data request by direct reception or by mirroring a network port or the like.
And S420, detecting the transmission line of the data request to obtain quality data of a plurality of transmission lines.
The transmission line detection method in this step can refer to the above embodiments, and is not described again.
S430, based on the quality data of each transmission line, generates a corresponding routing policy.
In implementation, after the proxy server obtains the quality data of each transmission line corresponding to the data request, one or more transmission lines can be selected from each transmission line according to the requirement of the application type to which the data request belongs on the transmission lines, so as to generate a routing strategy correspondingly. For example, if the delay and bandwidth requirements of the line are high for the game application, the line meeting the delay and bandwidth requirements can be selected from the transmission lines based on the requirements for transmitting the data request.
Further, the proxy server may forward the received data request based on the generated routing policy.
By the routing strategy generation method provided by the embodiment of the invention, a line can be detected based on a real user data request, and a proper transmission line is selected for transmitting a corresponding data request according to different line requirements, so that a corresponding routing strategy is generated, subsequent data requests of the same type can be transmitted based on the selected lines, the requirements of different application types on the transmission line are met, and the quality of a network server is improved; meanwhile, through convergence of a detection target and multiplexing of transmission line quality data, line detection requests can be greatly reduced, so that loads of a transmission line and a source station server caused by excessive detection requests are reduced, and high-quality feedback of service is preferentially ensured.

Optionally, the rule conversion module 120 may be further configured to generate the probe conversion rule, including: collecting destination addresses corresponding to the application types, and dividing according to the IP network segments; and selecting a destination address in each IP network segment to generate a detection request, sending the detection request to the detection module for detection, setting a detection address in a detection conversion rule corresponding to the IP network segment in the application type as the destination address when the server corresponding to the destination address is determined to respond normally, and determining that the corresponding detection rule is empty if servers corresponding to all the destination addresses in the IP network segment respond abnormally.

Optionally, the traffic identification module 110 receives the response information of the detection module, and may generate a corresponding routing policy based on quality data of each transmission line in the response information.
