Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic diagram illustrating a parameter configuration method according to an exemplary embodiment of the present application. As shown in fig. 1, the method includes:

s11, determining a corresponding application type according to the request information of the client;

s12, selecting a target optimization parameter group corresponding to the application type from a parameter calling library; the parameter calling library comprises at least one group of optimization parameter groups, and each group of optimization parameter groups comprises at least one optimization parameter;

and S13, configuring parameters used in the data transmission process of the target TCP connection responding to the request information of the client based on the target optimization parameter group.

According to the parameter configuration method, for received request information of a client, a target optimization parameter group is selected from a parameter calling library according to an application type corresponding to the request information, and based on the target optimization parameter group, parameters used in a data sending process of responding to the request information on a target TCP connection are configured. Therefore, the optimized parameters can be respectively configured for each TCP connection, and different parameter optimization processing can be performed on the same TCP connection at different time intervals, so that the differentiated requirements of services of different application types on the quality of the TCP connection are met, and the deployment of multiple services of different application types on the same server is facilitated.

For example, a CDN (Content Delivery Network) server needs to deploy multiple services, where the requirements of services of different application types on the quality of TCP connections are different, for example, some services require low bandwidth cost of TCP connections, and some services require high speed of TCP connections. When the method provided by the embodiment of the application is applied to the CDN server, the CDN server can configure optimization parameters meeting requirements for different application types of services, and therefore the various types of services deployed on the CDN server can provide high-quality network services.

In the embodiment of the application, by configuring the parameter call library, an optimized parameter group which is adaptive to the application type and balances performance and cost can be provided for services of different application types. Each group of optimization parameter groups in the parameter calling library comprises at least one of the following parameters:

(1) Parameter version number: in the optimization work of the TCP connection quality, the processing logic of the TCP protocol stack needs to be modified according to the change of the scene requirement and the update of the upstream open source community, and the optimization parameter set corresponding to the application type is adjusted. Thus, the parameter call library may be updated from time to time. The parameter version number is used to indicate the version of the parameter call library.

(2) Optimizing the scene corresponding to the parameter group: each set of optimization parameter sets in the parameter invocation library corresponds to at least one scenario. The applicable scenario is marked in each set of optimization parameter sets.

(3) Resetting a switch: the reset switch is used for indicating whether the parameters of the TCP connection are restored to default values configured in the kernel in advance. The parameters of the TCP connection can be restored to default values using the reset switch.

(4) And (3) a congestion control algorithm: configuring congestion control algorithms is an important part of regulating the behavior of the TCP protocol stack. The configuration of the congestion control algorithm may include configurations of algorithm types of the congestion control algorithm, such as a reno algorithm, a cubic algorithm, a bbr algorithm, and the like, and may further include configurations of related configuration items of the congestion control algorithm, where the related configuration items of the congestion control algorithm may include a hybrid slow start, a window-up speed, an additional window-up size, a retransmission rate threshold, and the like of the congestion control algorithm.

(5) Connecting initial window related configuration items: when a TCP connection starts, the TCP protocol stack configures initial windows of different sizes according to the current network state. The connection initiation window related configuration item includes at least one parameter in configuring the initiation window, such as a protocol stack initiation window and an initial slow start threshold.

The related configuration items connected with the initial window need to be actively configured, and can be discarded after the configuration is completed, so that the configuration items are not saved.

(6) Connection duration related configuration items: the configuration items related to the connection duration process comprise at least one parameter of processing flows such as Open, recovery, loss and the like in a TCP protocol stack state machine. The relevant configuration items in the connection duration process comprise at least one of the following items:

RTO-like parameters, such as RTO timer size;

speed compensation type parameters, such as extra window size;

a slow start class parameter, such as a window-up speed for a slow start period;

and fast retransmission classes, such as a trigger mechanism of fast retransmission, a retransmitted packet marking method, a window-dropping algorithm, and the like.

And after the configuration of the relevant configuration items in the continuous connection process is finished, the relevant configuration items are stored by the kernel and are called when the TCP protocol stack executes the corresponding flow.

It should be noted that, in some application scenarios, each set of optimization parameter sets includes a parameter version number, a scenario corresponding to the optimization parameter set, and a reset switch; one or more parameters of the congestion control algorithm, the connection initiation window related configuration item, and the connection duration related configuration item may be optional parameters.

In the embodiment of the application, the optimization parameter group comprises the parameter version number, so that the version of the optimization parameter group can be accurately indicated, and the parameter misuse is avoided; the method comprises a scene corresponding to an optimized parameter group, and can be used for conveniently judging whether the parameters of the TCP connection are wrong or not according to the scene and specific parameters during Debug (fault elimination); the server comprises a reset switch, which is beneficial to the daily maintenance of the server; including congestion control algorithms, connection initiation window related configuration items and connection duration related configuration items, parameters of the TCP connection can be optimized more comprehensively.

In some embodiments, at least one structure may be set in the parameter invocation library, where each structure corresponds to a set of optimization parameter sets.

As an exemplary implementation manner, referring to fig. 2, in step S12, selecting a target optimization parameter group corresponding to an application type from a parameter invocation library includes:

and step S121, the upper layer application selects an optimization parameter group corresponding to the scene from the parameter calling library based on the scene corresponding to the application type, and takes the selected optimization parameter group as a target optimization parameter group.

For example, if the scene corresponding to the application type is the scene a with low bandwidth cost, the optimization parameter group corresponding to the scene a is selected from the parameter call library as the target optimization parameter group. And configuring the target TCP connection corresponding to the request information of the client based on the target optimization parameter group, so that the bandwidth cost of the target TCP connection can be reduced.

According to the exemplary embodiment, the upper-layer application can select the target optimization parameter group meeting the scene requirement from the parameter calling library, and the target TCP connection is configured based on the target optimization parameter group, so that the quality requirement of the scene on the TCP connection can be met, and the service quality of the server is improved.

As an exemplary embodiment, referring to fig. 2, after step S121, the parameter configuration method further includes:

step S122, the upper layer application checks whether the parameter version number based on the target optimization parameter group and the kernel parameter version number are compatible;

step S123, if the verification result is compatible, the upper layer application sends the target optimization parameter set to the kernel through the first call system.

Generally, the update upgrade of the server kernel and the update upgrade of the upper layer application are often asynchronous. If any one of the kernel and the upper layer application is upgraded to a new version first, the situation that the respective parameter call libraries of the kernel and the upper layer application are incompatible may occur. For example, the optimized parameter set in the parameter call library of the upper layer application is version C1, and the parameter set maintained by the kernel has evolved to version C2 via upgrading, and has several deletions and additions compared with version C1, if only the latest version of parameters is supported, the kernel is no longer compatible with the parameter call library of the upper layer application once upgraded, thereby causing service interruption. On the contrary, if the parameter call library of the upper application is updated first and the new version kernel is not completely rolled out, the incompatibility is also caused. The version number is introduced to represent the form of the parameter group, and the parameter calling library and the kernel of the upper application are designed to simultaneously support the latest 2 versions, so that a time difference is reserved for asynchronous upgrading of the two versions.

According to the exemplary embodiment, the upper layer application checks whether the parameter version number of the selected target optimization parameter group and the kernel parameter version number are compatible, and sends the target optimization parameter group to the kernel under the condition of compatibility so as to improve the accuracy of TCP parameter setting.

Illustratively, the first calling system is setsockopt. In some embodiments, modifying the setsockopt system call, embedding code therein, may enable the target optimization parameter set issued by the upper layer application to be received by the kernel.

Illustratively, if the verification result is incompatible, the upper layer application disregards the target optimization parameter set.

As an example, in step S122, a process of checking based on whether the version numbers are compatible may refer to fig. 3, which includes:

step S21, reading a parameter VERSION number LIB _ VERSION of an upper application;

s22, reading a parameter VERSION number KERNEL _ VERSION of the KERNEL;

step S23, judging whether LIB _ VERSION = KERNEL _ VERSION or LIB _ VERSION N = KERNEL _ VERSION-1 is true or not; if yes, go to step S24; otherwise, entering step S25;

step S24, determining the use parameter VERSION number as a parameter of LIB _ VERSION;

step S25, judging whether LIB _ VERSION-1= KERNEL _VERSIONis true or not; if yes, go to step S27; otherwise, entering step S26;

step S26, determining a parameter with a use parameter VERSION number (LIB _ VERSION-1);

and S27, the difference value between the parameter version number of the upper application and the parameter version number of the kernel is larger than 1, and the verification result is incompatible.

In this example, both the upper layer application and the kernel support the latest two-version parameters simultaneously. Based on the method, whether a difference exists between the parameter version number of the upper layer application and the parameter version number of the kernel is checked, and whether the difference is 1 is checked. If there is a difference and the difference is greater than 1, the verification result is incompatible. And if the difference value does not exist or is 1, selecting the parameters of the low version supported by the upper application and the kernel together.

According to the example, the upper layer application and the kernel are asynchronously updated within a certain time range, and version number verification results can also be compatible. In other words, compatibility can continue regardless of which of the upper layer application and the kernel was upgraded first, as long as the two differ by no more than one version. And the flexibility of updating the parameter calling library is improved.

As an exemplary embodiment, referring to fig. 4, the parameter configuration method may further include:

and step S124, the kernel checks the received target optimization parameter group, and if the check result is that the check is passed, the kernel saves the target optimization parameter group transmitted by the upper layer application through the first calling system.

In this exemplary embodiment, after the verification is applied to the upper layer, the kernel also verifies the received target optimization parameter set, so as to prevent the target optimization parameter set sent to the kernel from being unsuitable for the target TCP connection. The accuracy of parameter configuration is improved.

Illustratively, the processing of the kernel to check the received target optimization parameter group includes at least one of:

the kernel checks the length of the target optimization parameter group;

the kernel checks the version number of the target optimization parameter group;

the kernel determines whether the target TCP connection issues a reset instruction before starting to send data for the client;

the inner core performs validity checking on the name of the congestion control algorithm.

The sequence of the above processing is not limited, for example, the version number may be checked first, and then the length may be checked; or the length can be checked first and then the version number can be checked.

If the length of the target parameter group meets the preset condition, determining that the length check is passed; if the version number of the target parameter set meets the preset condition, determining that the version number passes verification; if the target TCP connection does not issue a reset instruction before the data aiming at the client end is sent, the reset check is passed; and if the name of the congestion control algorithm meets the preset condition, the verification of the congestion control algorithm is passed.

In addition, the kernel may or may not check the version number of the target optimization parameter set; for example, in one case, the kernel and the application layer (or the upper layer application) are better matched or have better compatibility, then the upper layer application may only perform the processing of checking the version number of the target optimization parameter set (the foregoing example of the specific checking method of the upper layer application has been described in detail, and is not described again here); in another case, the matching between the kernel and the upper layer application is poor, or when the user configures that the upper layer application and the kernel both perform the processing of checking the version number of the target optimization parameter set, then both the upper layer application and the kernel perform the checking of the version number.

Fig. 5 shows a specific example of a verification process in the parameter configuration method. Firstly, the upper layer application checks the parameter version number; and after the verification is passed, triggering a first calling system, namely setsockopt system calling, and receiving the target optimization parameter group by the kernel. Then, the kernel checks the length and version number of the target parameter group, whether a reset instruction is sent or not, and the name of the congestion control algorithm. After all the verification passes, if the data transmission is started at present, setting an initial window and then storing all parameters in a target optimization parameter set issued by an upper application; if the data is sent currently, all parameters in the target optimization parameter set issued by the upper layer application are saved.

In the exemplary embodiment, the target optimization parameter group is comprehensively checked, so that the accuracy and stability of parameter configuration can be improved.

Illustratively, when the TCP protocol stack is executed to the corresponding flow, the kernel may call the corresponding parameter to optimize the TCP protocol stack according to the stored target optimization parameter group.

As an exemplary embodiment, the parameter configuration method further includes:

when receiving a target optimization parameter group, the inner core records a sequence number of a first data packet which is currently sent to a target TCP connection;

and the kernel configures the target optimization parameter group to be effective under the condition of determining that the confirmation information aiming at the first data packet is received.

If the kernel sends at least one data packet to the target TCP connection according to the previously configured parameters when the upper layer application issues the target optimization parameter set to the kernel, the time when configuring the target optimization parameter set to be valid is determined according to the exemplary embodiment.

For example, as shown in fig. 6, the kernel receives a new target optimization parameter set during the validity period of the old target optimization parameter set, records the sequence number N of the first data packet that has been currently transmitted, and still uses the old target optimization parameter set. The kernel receives ack packets corresponding to the sent data packets, and when the sequence numbers of the ack packets sent by the client are continuously increased until the sequence number N is reached, the new target optimization parameter group is configured to be effective. Here, the old target optimization parameter group may be an optimization parameter corresponding to another data transmission process, or may be understood as a target optimization parameter configured when the other data transmission process performs optimization processing on a parameter of the part of data in a process of performing data transmission using a TCP connection.

According to the exemplary embodiment, since the time for the switched parameters to take effect is that all the data packets sent before the target optimization parameter group is configured are confirmed, the parameters can be switched in the continuous process of one TCP connection, the switched parameters can take effect orderly, and the stability of parameter configuration is improved.

In some embodiments, the linked list may be used to store the target optimization parameter sets issued to the cores one by one, and each time an ack packet is received, the corresponding target optimization parameter set is taken out from the linked list according to the packet sequence number corresponding to the ack packet, and configured to be valid. The specific process can be implemented with reference to fig. 7.

As an exemplary embodiment, the parameter configuration method may further include:

and the kernel reports the optimized parameters used by the target TCP connection to the upper layer application through a second calling system.

In the exemplary embodiment, the kernel reports the optimized parameters used by the target TCP connection, so that the upper layer application updates information in time, and the stability of parameter configuration is improved.

Illustratively, the second calling system is getsockopt. In some embodiments, a getsockopt system call is modified in which code is embedded to implement functionality for the kernel to report back to the upper layer the optimized parameters used by the target TCP connection.

According to the method of the embodiment of the application, for the received request information of the client, the target optimization parameter group is selected from the parameter calling library according to the application type corresponding to the request information, and based on the target optimization parameter group, the parameters used in the data sending process of the target TCP connection responding to the request information are configured. Therefore, the optimized parameters can be respectively configured for each TCP connection, and different parameter optimization processing can be performed on the same TCP connection at different time intervals, so that the differentiated requirements of services of different application types on the quality of the TCP connection are met, and the deployment of multiple services of different application types on the same server is facilitated.
