Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In the conventional data transmission process, coupling management is generally performed in two ways, for example, the Linux Kernel module lksctp (Linux Kernel sctp) provides two coupling management ways for the server application.
In the first coupling management method called udp-style like, the system provides a socket resource of SOCK _ SEQPACKET type, and after the monitoring is started, all couplings connected to the monitoring port are associated with the socket resource, so as to form a many-to-one relationship in which a plurality of couplings are bound to the same socket resource. The coupling management mode has a poor support effect on the multi-thread concurrent access, and because the data from a plurality of couplings are stored in the same receiving (or sending) buffer area, the multi-thread access from the user layer is executed in a serialized manner in the system kernel, the real effect of the concurrent access cannot be achieved, and the performance bottleneck in the case of large throughput is easy to occur. In a second coupling management mode called tcp-style like, the system provides socket resources of an SOCK _ STREAM type, and after a listening port is started, any coupling connected with the listening port can be associated with the coupling by creating a new socket resource, so that a one-to-one relationship that each coupling is individually bound with one socket resource is formed. The coupling management mode is suitable for multithreading to access different socket resources respectively, can give full play to the concurrency performance of the system, and has the defect that socket resources are consumed too fast, and are not beneficial to connection and management of a large number of couplings.
Compared with the udp-style link coupling management mode, the coupling management method, the coupling management device and the coupling management system in data transmission can completely access and process different couplings belonging to different socket resources in parallel, and improve the concurrency rate and the throughput to the maximum extent; compared with a tcp-style like coupling management mode, one socket resource is not limited to binding one coupling, and a large number of couplings can be accommodated and managed more effectively.
The coupling management method in data transmission provided by the present invention can be applied to the application environment shown in fig. 1, in which the terminal 102 communicates with the server 104 through a network. When the user layer needs to perform priority migration on the high-priority couplings, a request can be sent to a server through a terminal, and the high-priority couplings are migrated to first socket resources in a socket resource group in a one-to-one correspondence mode through the server; and migrating each low-priority coupling to each second socket resource in the socket resource group according to an average allocation rule, so that the concurrent throughput of the socket resources and the data is balanced, and the coupling management efficiency is improved. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a coupling management method in data transmission is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:
step S210, migrating each high-priority coupling to each first socket resource in the socket resource group in a one-to-one correspondence manner; the number of first socket resources is the same as the number of high priority couplings.
Wherein, coupling refers to a corresponding relationship between two SCTP endpoints. The association contains the two SCTP endpoints and protocol state information including information such as the authentication tag and the transport sequence number. High priority couplings refer to couplings having a high priority level, wherein the priority level of the coupling may be customized by the user layer. For example, the user layer may set a portion of the special couplings as high-priority couplings according to actual traffic needs. Socket refers to a communication mechanism by which development of a client/server system can occur either locally on a stand-alone machine or across a network. For example, the functions provided by Linux (e.g., print services, ftp, etc.) are typically communicated through sockets. The socket resources include a source IP address, a destination IP address, a source port number, a destination port number, and the like. The first socket resource refers to a socket resource for associating high priority couplings. The socket resource group is composed of a certain number of socket resources preset in the system.
Specifically, all the couplings may be prioritized according to the actual service requirements. The high-priority couplings can be migrated to the first socket resources in the socket resource group in a one-to-one correspondence manner, wherein the number of the first socket resources is the same as the number of the high-priority couplings, so that one high-priority coupling is associated with a single first socket resource, and better throughput performance is provided for the high-priority couplings.
Step S220, migrate each low priority couple to each second socket resource in the socket resource group according to the average allocation rule.
Wherein the average allocation rule is used to allocate each low priority couple to each second socket resource. For example, if there are 6 low priority couplings allocated to 3 second socket resources on average, each second socket resource allocation results in 2 low priority couplings, that is, 2 low priority couplings are migrated to one second socket resource. And 7 low-priority couplings are averagely distributed to 3 second socket resources, each second socket resource is distributed to obtain 2 low-priority couplings, and the rest low-priority couplings are randomly distributed to any second socket resource. The second socket resource refers to a socket resource for associating low priority couplings.
Specifically, all the couplings may be prioritized according to the actual service requirements. For low-priority couplings, each low-priority coupling can be migrated to each second socket resource in the socket resource group according to an average allocation rule, so that the data concurrency rate and the throughput are improved to the maximum extent.
In a specific embodiment, if there is no special coupling according to the actual traffic demand, it is required to provide higher priority and throughput performance, i.e. there is no need to set high priority couplings. All the couplings can default to low priority couplings and each low priority coupling can be migrated to each second socket resource in the socket resource group according to the average allocation rule. The method realizes the management of a large number of couplings under the limited socket resource, and improves the overall concurrent throughput while effectively using the socket resource.
In the above embodiment, in data transmission, when there is a high-priority coupling that needs to be associated with a socket resource, each high-priority coupling may be migrated to each first socket resource in a socket resource group in a one-to-one correspondence manner, where the number of the first socket resources is the same as the number of the high-priority couplings, so that a user layer may designate a separate socket resource (first socket resource) for the high-priority coupling to be associated according to an actual service requirement, and provide higher throughput performance for the high-priority coupling. In data transmission, for low-priority couplings in a coupling group, each low-priority coupling can be migrated to each second socket resource in a socket resource group according to an average allocation rule, so that a large amount of couplings can be managed under the condition of limited socket resources, the overall concurrent throughput is improved while the socket resources are effectively used, and the coupling management efficiency is improved.
In one embodiment, as shown in FIG. 3, a first flow diagram of a low priority coupled migration step is shown. Wherein migrating each low-priority coupling to each second socket resource in the socket resource group according to the average allocation rule comprises:
step S310, inquiring the socket serial number of the second socket resource which is equal to the index value, and confirming the second socket resource corresponding to the socket serial number as the target socket resource; the index value is obtained by taking the modulus of the number of the second socket resources to the number of the coupling numbers of the low-priority couplings.
The target socket resource refers to a second socket resource with a socket sequence number equal to the index value. The socket number refers to the number of the second socket resource. For example, all the second socket resources may be numbered in an order from 1 to n, where the socket number is any one of numbers from 1 to n, and n is a positive integer. The coupling number value refers to the number of the low priority coupling. For example, all low priority couplings may be numbered in an order of 1 to n, so that the coupling number is any one number from 1 to n, and n is a positive integer. The index value is obtained by taking the modulus of the number of the second socket resource to the number of the low-priority coupled coupling numbers.
Specifically, according to the number of the second socket resources, a modulus is taken for the coupling number value of the low-priority coupling to obtain an index value corresponding to the low-priority coupling; the socket serial number equal to the index value can be obtained by inquiring the socket serial number of the second socket resource, and the second socket resource corresponding to the socket serial number is confirmed as the target socket resource. And further, the target socket resource is obtained.
Step S320, migrating the low-priority coupling to the target socket resource.
Specifically, when a target socket resource corresponding to a low-priority coupling is obtained, the low-priority coupling may be migrated to the target socket resource. The association of the low-priority coupling with the target socket resource is achieved.
For example, the number of the low-priority couplings and the number of the second socket resources are modulo to obtain the index value m, then the second socket resource with the socket serial number m is selected as the target socket resource, and the low-priority couplings are migrated to the target socket resource. Furthermore, one socket resource is not limited to be associated with one coupling, so that the socket resource is more effectively used for accommodating and managing a large number of couplings, and the coupling management efficiency is improved.
In one embodiment, as shown in FIG. 4, a second flow diagram of a low priority coupled migration step is shown. The method comprises the following steps:
step S410, inquiring the socket serial number of the second socket resource which is equal to the index value, and confirming the second socket resource corresponding to the socket serial number as the target socket resource; the index value is obtained by taking the modulus of the number of the second socket resources to the number of the coupling numbers of the low-priority couplings.
The specific content process of step S410 may refer to the above content, and is not described herein again.
Step S420, if the target socket resource is in the unavailable state, the identity information corresponding to the monitored socket resource is separated according to the monitored socket resource, and the identity information is assigned to the target socket resource.
Wherein, listening socket resource refers to socket resource with listening function. Identity information refers to information indicating the identity of a socket resource.
Preferably, the identity information comprises local address and port information.
Specifically, when a target socket resource having a socket sequence number equal to the index value is acquired, it may be checked whether the target socket resource has been used and allocated in association. If the target socket resource is in the unavailable state, the identity information which is the same as the monitoring socket resource can be separated according to the preset monitoring socket resource, and the identity information is endowed to the target socket resource. And then separating to obtain a second socket resource which is used for the same identity information with the monitoring socket resource, and taking the second socket resource as the target socket resource.
Further, if the target socket resource is found to be in an available state, the corresponding low-priority coupling is directly migrated to the target socket resource.
Step S430, migrate the low-priority coupling to the target socket resource.
The specific content process of step S430 may refer to the above content, and is not described herein again.
In a specific embodiment, step S410 is preceded by:
generating a COMM _ UP event corresponding to the low-priority coupling according to a stream control transmission protocol;
the number of couples corresponding to the low priority couple in the COMM _ UP event is obtained.
Stream Control Transmission Protocol (SCTP) is a protocol for simultaneously transmitting a plurality of data streams between two ends of a network connection. The COMM _ UP event refers to a connection setup complete event.
Specifically, when the SCTP handshake completes the connection establishment, a COMM _ UP event corresponding to a low-priority coupling may be generated through a COMMUNICATIONs UP notification primitive, and further, a coupling number value corresponding to the low-priority coupling in the COMM _ UP event may be obtained.
It should be noted that, when capturing a COMM _ UP event, information such as event state information corresponding to low-priority coupling, an opposite-end destination address list, an outgoing flow number, an incoming flow number, and the like may also be acquired.
In the above embodiment, in data transmission, for a low-priority coupling in a coupling group, an index value m may be obtained according to a coupling number value modulo polling rule, that is, according to a coupling number value of the low-priority coupling and a total number of second socket resources modulo, and then an mth second socket resource is selected to be associated with the low-priority coupling. The method and the device realize the management of a large number of couplings under the limited socket resource, improve the overall concurrent throughput and improve the coupling management efficiency while effectively using the socket resource.
In a specific embodiment, as shown in FIG. 5, a third flow diagram of the low priority coupled migration step is shown. The specific working process of the low-priority coupled migration may include the following steps (step 1 to step 5):
And 2, obtaining an index value n by taking a module according to the obtained number value of the low-priority coupling and the total number n of the second socket resources, and migrating the low-priority coupling corresponding to the index value n to the nth second socket resource for management.
And 3, checking whether the nth second socket resource is used and allocated for migration, and if the nth second socket resource is not available, performing the step 4.
And 4, applying for socket resources according to a preset monitoring socket source, and separating a socket resource which has the same local address and port information with the monitoring socket resource.
And 5, establishing an association relation between the low-priority coupling with the corresponding index value n and the second socket resource by taking the monitoring socket resource, the coupling number value and the second socket resource as input parameters under the condition that the nth second socket resource is available, and realizing the transfer of the low-priority coupling to the second socket resource.
Based on the embodiment, by changing the incidence relation between the low-priority couplings and the second socket resources, the many-to-one and one-to-one relation of the traditional coupling management mode is expanded, and the many-to-many relation of binding a plurality of low-priority couplings and the non-single second socket resources is formed. The concurrency rate and the throughput of data transmission are improved to the maximum extent, and the coupling management efficiency is improved.
In one embodiment, as shown in fig. 6, a coupling management method in data transmission is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:
step S610, migrating each high priority coupling to each first socket resource in the socket resource group in a one-to-one correspondence manner; the number of first socket resources is the same as the number of high priority couplings.
The specific content process of step S610 may refer to the above content, and is not described herein again.
Step S620, cache the coupled data with high priority coupling to the corresponding buffer area of the first socket resource.
Specifically, the high-priority couplings are migrated to the first socket resource, that is, after the high-priority couplings are associated with the first socket resource, the coupling data of the high-priority couplings may be cached in a buffer of the first socket resource. The buffer may be a receiving buffer of the first socket resource, or may be a transmitting buffer of the first socket resource. The coupling data refers to unprocessed data associated with the high priority coupling. The method realizes the change of the incidence relation between the high-priority coupling and the first socket resource, and simultaneously transfers the unprocessed data related to the high-priority coupling to the buffer area of the first socket resource.
Step S630, migrate each low priority coupling to each second socket resource in the socket resource group according to the average allocation rule.
The specific content process of step S630 may refer to the above content, and is not described herein again.
In the above embodiment, when there is a high-priority coupling that needs to be associated with a socket resource in data transmission, each high-priority coupling may be migrated to each first socket resource in the socket resource group in a one-to-one correspondence manner, and the coupling data of the high-priority coupling is cached in the buffer area of the corresponding first socket resource. The user layer can assign independent socket resources (first socket resources) to the high-priority coupling according to actual service requirements to be associated, and higher throughput performance is provided for the high-priority coupling. In data transmission, for low-priority couplings in a coupling group, each low-priority coupling can be migrated to each second socket resource in a socket resource group according to an average allocation rule, so that a large amount of couplings can be managed under the condition of limited socket resources, the overall concurrent throughput is improved while the socket resources are effectively used, and the coupling management efficiency is improved.
In one embodiment, as shown in fig. 7, a coupling management method in data transmission is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:

Specifically, after the low-priority coupling is migrated to the second socket resource, that is, the low-priority coupling is associated with the second socket resource, the coupling data of the low-priority coupling may be buffered in a buffer of the second socket resource. The buffer may be a receiving buffer of the second socket resource, or may be a transmitting buffer of the second socket resource. Coupled data of a low priority coupling refers to unprocessed data associated with the low priority coupling. The method realizes the change of the association relationship between the low-priority coupling and the second socket resource, and simultaneously transfers the unprocessed data related to the low-priority coupling to the buffer area of the second socket resource.
