On the other hand, due to the high sensitivity and the high aggregation of users in scenes such as internet bars, hotels and the like, the size and the severity of complaints caused by user group faults are far larger than those of household broadband individual users, so that the normal business of merchants is greatly influenced, and the loss of customers is caused.

Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The application provides a traffic distribution method, which can be applied to a system architecture as shown in fig. 1. In the system architecture, an application server, a traffic distribution device and a user client can be included. The traffic distribution device may respond to the request and transmit data traffic between the user client and the requested application server through the acceleration link.
In this embodiment, a plurality of user clients may share the same source IP address. For example, in an application scenario of an internet bar, an institution, an enterprise, and the like, a plurality of user clients may be in the same local area network, and the user clients may have different intranet IP addresses in the local area network, but external public network IPs of the user clients may be the same source IP, that is, the source IP address is a public network IP address. Thus, the traffic distribution device can receive different acceleration requests from the same source IP, and can process each acceleration request respectively to implement the acceleration function of the application program.
In this embodiment, the application program may be software such as a network game, a video playing application program, and a browser, and the acceleration link may refer to a transmission link established between the traffic distribution device and the application server and the user client. For example, an acceleration platform vendor may act as a traffic distribution device (or become an acceleration node) by deploying a proxy server or a two-wire VPN server. When the user client sends a data request to the application server through the acceleration client, the acceleration client may send the data request to the traffic distribution device, and then the traffic distribution device selects an acceleration link with better communication quality, and transmits the data traffic between the application server and the user client through the selected acceleration link.
Specifically, an embodiment of the present application may provide a traffic distribution method applied to the traffic distribution device. In the traffic distribution device, an acceleration link list of each application may be stored, and in the acceleration link list, a plurality of available acceleration links may be included.
In one embodiment, the accelerated link list of each application stored in the traffic distribution device may be established after the network environment is tested. In order to establish the accelerated link list for different applications, corresponding link screening thresholds may be set for the different applications first, considering that the network quality requirements of the different applications are usually different. The link screening threshold may be used to select acceleration links meeting acceleration conditions from a plurality of candidate acceleration links, and the selected acceleration links may be added to an acceleration link list of the application program as available acceleration links. In practical applications, the link screening threshold may be one parameter or a combination of multiple parameters. For example, the link screening threshold may be a parameter that characterizes a link delay, or may be multiple parameters that characterize the link delay, a link packet loss rate, and a link jitter value. The process of setting the link screening threshold for the application program may be manually set by an administrator of the traffic distribution device, or may be automatically set and updated according to the requirement of the application program on the network quality.
In one embodiment, taking a target application to be accelerated as an example, after setting a link screening threshold for the target application, the traffic distribution device may determine each candidate acceleration link with the target application server. The candidate acceleration link may enable data transfer between the traffic distribution device and the target application server, but the quality of the data transfer may need to be further evaluated. Specifically, the traffic distribution device may traverse each of the candidate acceleration links described above, and dial-test the server address of the target application through each of the candidate acceleration links. The server address may be an IP address of the server of the application program, or a combination of the IP address of the server of the application program and the access port.
In practical applications, the implementation manner of dial testing may include multiple ways, for example, the traffic distribution device may issue a PING or TCPING command for the server address of the target application program, and identify a parameter representing network transmission quality from response data fed back by the target application program server, and this part of the parameter may be used as a dial testing result for the target application program. In practical applications, the dialing test result and the link screening threshold are generally consistent in type, for example, if the link screening threshold is a delay threshold, the dialing test result may be a transmission delay between the traffic distribution device and the target application server. For another example, if the link screening threshold is a delay threshold, a packet loss rate threshold, or a delay jitter threshold, the dialing test result may be transmission delay, packet loss rate, or delay jitter between the traffic distribution device and the target application server.
In this embodiment, after receiving the dial-up test result returned by the target application server, the traffic distribution device may compare the dial-up test result with the set link screening threshold. If the dial test result of the current candidate acceleration link meets the link screening threshold requirement, it indicates that the transmission quality of the current candidate acceleration link meets the requirement, so that the current candidate acceleration link can be used as an available acceleration link and added to the acceleration link list of the target application program. Specifically, if the dialing test result of the current candidate acceleration link meets the link screening threshold requirement, the numeric value of the dialing test result may be within a numeric range defined by the link screening threshold. For example, if the link screening threshold is an upper limit value, if the dial test result of the current candidate acceleration link is less than or equal to the link screening threshold, it indicates that the transmission quality of the current candidate acceleration link meets the requirement. In this way, by traversing the candidate acceleration link, a plurality of available acceleration links with better transmission quality can be screened out from the plurality of candidate acceleration links, and the available acceleration links can be added to the acceleration link list of the target application program.
In one embodiment, the link screening threshold may include three indicators: after configuring a link screening threshold for the target application program, the delay threshold, the packet loss rate threshold and the delay jitter value threshold may be respectively counted for the delay, the packet loss rate and the delay jitter value from the outlet of each candidate acceleration link to the target application program server. Specifically, to reduce the error of data statistics, the dial testing process may last for a certain duration. Within the period of time, the server address of the target application program can be dialed and tested for many times, the mean values of the parameters such as the time delay, the packet loss rate and the time delay jitter value can be finally calculated respectively, and the calculated mean values can be used as the final dialing and testing result. Subsequently, the parameters may be compared with the corresponding link screening thresholds one by one, so as to determine whether the current candidate acceleration link meets the requirement.
Specifically, if the time delay, the packet loss rate, and the time delay jitter value of the current candidate acceleration link are respectively less than or equal to the time delay threshold, the packet loss rate threshold, and the time delay jitter threshold, it indicates that each parameter is within a range defined by the threshold, and at this time, the current candidate acceleration link may be added to the acceleration link list of the target application program.
It should be noted that, the above time delay, the packet loss rate, and the time delay jitter value are taken as examples, and the technical solution of the present application is only for convenience of explanation, but this does not indicate the technical solution of the present application, and is only applicable to a scenario of the time delay, the packet loss rate, and the time delay jitter value. It should be known to those skilled in the art that in practice, the dial-test result may include more or less parameters, and different parameters may have different weight values. When determining whether the candidate acceleration link meets the requirement, the size relationship between each parameter and the corresponding threshold value can be compared one by one, or each parameter can be fitted to obtain a comprehensive index, and then the comprehensive index is compared with the index threshold value. These modifications and variations are considered to be within the spirit of the present disclosure and, therefore, all such modifications and variations are intended to be included within the scope of the present disclosure.
In one embodiment, the number of available acceleration links obtained by screening in the above manner may be too large or too small, and in this case, the number of available acceleration links in the acceleration link list may be flexibly adjusted by adjusting the link screening threshold. In particular, a quantity screening threshold may be further provided in the traffic distribution device, and the quantity screening threshold may be used to determine whether the quantity of the acceleration links available in the acceleration link list meets the requirement. If the number of the available acceleration links in the acceleration link list is smaller than the number screening threshold after the candidate acceleration links are traversed, it indicates that the number of the available acceleration links in the acceleration link list is small, and at this time, the link screening threshold may be updated, so as to increase the number of the available acceleration links in the acceleration link list. For example, the link filtering threshold may be increased step by step, and the number of available acceleration links in the acceleration link list is counted once after each link filtering threshold is changed, until the number of available acceleration links in the acceleration link list is greater than or equal to the number filtering threshold.
Referring to fig. 2 and fig. 3, the application and the traffic distribution method in the traffic distribution device provided in the present application may include the following steps.
S1: a plurality of target acceleration requests directed to the target application from the same source IP address are received.
In this embodiment, the traffic distribution device may receive acceleration requests from the same source IP address, and these acceleration requests may be directed to different applications, where the source IP address is a public IP address, and the acceleration requests from the same source IP address may be from different users in the same local area network respectively.
After receiving the acceleration requests, the traffic distribution device may identify the application programs corresponding to the respective acceleration requests. Specifically, the acceleration request sent by the user client may carry a server address of the application program. In the traffic distribution apparatus, however, there may also be a mapping table between the application and the server address. Therefore, after receiving the acceleration requests sent by the same source IP address, the traffic distribution equipment can identify the server addresses carried in the acceleration requests, and can query the identified server addresses in the mapping table, so as to determine the application programs corresponding to the acceleration requests.
Furthermore, acceleration requests for different applications typically carry different packet characteristics. The packet characteristics may be analyzed based on a series of information such as a message structure, a communication protocol, an access address and a port in the acceleration request. In practical applications, feature extraction tools such as wireshark, tcptrace, tstat, etc. may be employed to identify packet features in acceleration requests. Meanwhile, in the traffic distribution apparatus, there may be a mapping table between the application and the packet characteristics. In this way, after receiving the acceleration requests sent by the same source IP address, the traffic distribution device can identify the packet characteristics of each acceleration request, and can query the identified packet characteristics in the mapping table, thereby determining the application program corresponding to the acceleration request.
In this way, for a target application, after receiving multiple acceleration requests from the same source IP address, the traffic distribution device may screen multiple target acceleration requests directed to the target application from the multiple acceleration requests. Specifically, the traffic distribution device may identify a server address and/or a packet characteristic of each acceleration request, and if the identified server address and/or packet characteristic matches the target application, may use the acceleration request as a target acceleration request directed to the target application.
In an embodiment, if an application program matched with an acceleration request is not queried through a server address and a data packet feature, it indicates that the application program corresponding to the acceleration request does not open an acceleration service, at this time, a traffic corresponding to the acceleration request may be distributed to a default route, and data between a server of the application program and a user client may be transmitted through the default route.
S3: and responding to the plurality of target acceleration requests, and distributing the traffic of the target application program requested by the same source IP address to a plurality of acceleration links in the acceleration link list.
In this embodiment, for a target acceleration request directed to a target application, the traffic distribution device may forward data of the target application server to the user through the acceleration link, and at the same time forward data of the user to the target application server. In the process, a plurality of acceleration requests from the same source IP address and pointing to the target application program can be distributed to different acceleration links in the acceleration link list, so that the problem that all communication of users under the same source IP is interrupted when one or more links with the best quality fail can be avoided.
In this embodiment, traffic corresponding to a plurality of target acceleration requests may be distributed among a plurality of available acceleration links according to a plurality of policies. For example, the traffic distribution device may randomly select one available acceleration link from the acceleration link list of the target application for traffic distribution according to the current target acceleration request. In some application scenarios, in order to ensure that load balancing is achieved among the available acceleration links, traffic of the target application program requested by the same source IP address may be distributed to the acceleration links in the available acceleration link list based on a load balancing policy.
In practical application, the traffic distribution device may follow a source IP polling policy, and specifically, for multiple target acceleration requests directed to a target application program, the traffic distribution device may sequentially distribute, according to an ordering order of available acceleration links in an acceleration link list, traffic corresponding to the multiple target acceleration requests to different available acceleration links. For example, in the target application acceleration link list, there are currently three available acceleration links, a, B, and C. Then when the traffic distribution device receives a first acceleration request directed to the target application, the acceleration link a may be used as the acceleration link corresponding to the first acceleration request. When the traffic distribution device receives a second acceleration request directed to the target application program, the acceleration link B may be used as an acceleration link corresponding to the second acceleration request, and so on. After receiving the fourth acceleration request, a new round of training process may be resumed, and the acceleration link a is used as the acceleration link of the fourth acceleration request. In addition, the traffic distribution device may also distribute, according to a minimum connection policy, the current traffic of the target application program requested by the same source IP address to the acceleration link with the smallest load in the acceleration link list.
Of course, in practical applications, the traffic distribution device may also adopt other load balancing strategies. For example, the traffic distribution device may employ a consistent hash algorithm, convert the current acceleration request into a hash value, and distribute an acceleration link corresponding to the converted hash value to the current acceleration request.
Of course, if there is no available acceleration link in the current acceleration link list, the traffic corresponding to the current acceleration request is distributed to the default route, and the data between the server of the application program and the user client is transmitted through the default route, or a new acceleration node is introduced to obtain a new acceleration link to meet the requirement of the acceleration link.
The application also provides a traffic distribution device, which is provided with an acceleration link list of a target application program, wherein the acceleration link list comprises a plurality of available acceleration links. Referring to fig. 4, the traffic distribution apparatus includes:
the request receiving unit is used for receiving a plurality of target acceleration requests which are from the same source IP address and point to the target application program, wherein the source IP address is a public network IP address, and the acceleration requests of the same source IP address can be from different users in the same local area network respectively;
and the traffic distribution unit is used for responding to the plurality of target acceleration requests and distributing the traffic of the target application program requested by the same source IP address to a plurality of acceleration links in the acceleration link list.
In one embodiment, the traffic distribution apparatus further comprises:

a threshold comparison unit, configured to traverse candidate acceleration links, dial and test a server address of the target application program through each candidate acceleration link, and compare a dial-test result with the link screening threshold;
and the list establishing unit is used for adding the current candidate acceleration link into the acceleration link list of the target application program as an available acceleration link if the dialing test result of the current candidate acceleration link meets the link screening threshold requirement.
In one embodiment, the traffic distribution unit is further configured to distribute traffic polls of the target application requested by the same source IP address to each acceleration link in the acceleration link list; or the method is also used for distributing the current flow of the target application program requested by the same source IP address to the acceleration link with the minimum load in the acceleration link list.
The present application further provides a traffic distribution device, please refer to fig. 5, where the traffic distribution device includes a memory and a processor, the memory is used for storing a computer program, and when the computer program is executed by the processor, the traffic distribution device implements the traffic distribution method described above.

The computer terminal 10 may include one or more (only one shown) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission module 106 for communication functions. It will be understood by those skilled in the art that the structure shown in fig. 6 is only an illustration and is not intended to limit the structure of the electronic device. For example, the computer terminal 10 may also include more or fewer components than shown in FIG. 6, or have a different configuration than shown in FIG. 6.
The memory 104 may be used to store software programs and modules of application software, and the processor 102 executes various functional applications and data processing by executing the software programs and modules stored in the memory 104. The memory 104 may include high speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory located remotely from the processor 102, which may be connected to the computer terminal 10 over a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
The transmission device 106 is used to receive or transmit data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider of the computer terminal 10. In one example, the transmission device 106 includes a Network adapter (NIC) that can be connected to other Network devices through a base station so as to communicate with the internet. In one example, the transmission device 106 can be a Radio Frequency (RF) module, which is used to communicate with the internet in a wireless manner.
As can be seen from the above, according to the technical solution provided by the present application, for a target application to be accelerated, a traffic distribution device may store an acceleration link list of the target application. In the acceleration link list, a plurality of available acceleration links may be included. When receiving a plurality of target acceleration requests from the same source IP address and directed to the target application program, the traffic distribution device may distribute the traffic of the target application program requested by the same source IP address to a plurality of acceleration links in the acceleration link list, instead of distributing the traffic of the target application program to the same acceleration link, so that the problem that when one or more optimal acceleration links with the best quality fail, all the acceleration requests under the same source IP are interrupted in communication can be avoided, thereby improving the stability of traffic distribution.
