Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a port connection system, a port connection method, and a computer device.
Background
With the rise of the industrial internet, more and more factory devices need to access the internet. For port communication among sub-units in the equipment or among different equipment, the access modes of the ports in the current products mainly comprise the following steps:
1. fixed ports, i.e. the ports are allocated in advance to programs, units, devices, etc. which need to communicate. However, the existing environment in which the device is located may not be consistent with the preset deployment environment, and thus, there is a high likelihood that the fixed port is already occupied;
2. all ports of more than one device may start cycling from a certain port, automatically increment once occupied, and allocate the next port. This way, it is possible to avoid situations where ports are already occupied and cannot be allocated. However, if the corresponding allocation policy exceeds the maximum port number, the port cannot be allocated again even if any;
3. in order to solve the problem in the second mode, taking the module when the port number reaches the maximum value, so that the port can be reassigned from the beginning, that is, the port occupied by the previous assignment is released after the use, and the reassignment can screen out the port in the partial available state. The problem that the port number exceeds the maximum value can be solved by the method, but the mode taking reassignment inevitably generates the condition that the port number can be found out by being distributed for a plurality of times, for example, the port number starts from the beginning and is counted once every +1, if the port is occupied, the port is again +1, and thus a certain resource waste can be caused.
Therefore, the prior art has the technical problem of low port connection efficiency caused by a port random allocation mode.

Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the application belong. The terms (such as those defined in commonly used dictionaries) will be interpreted as having a meaning that is the same as the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in connection with the various embodiments of the application.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic diagram of a system composition of a port connection system according to an embodiment of the present application.
The port connection system 10 includes an output unit 11, a port synchronization unit 12, and at least one preset receiving unit 13, where the output unit 11 and each preset receiving unit 13 are respectively connected to the port synchronization unit 12.
The output unit 11 is configured to send a connection request to the port synchronization unit 12, where the connection request includes first destination identification information, second destination identification information, and an output port number corresponding to a destination output port 111 of the output unit 11. The first target identification information is first preset identification information of a port connection device to which any preset receiving unit 13 belongs, and the second target identification information is second preset identification information corresponding to any preset receiving unit 13.
Specifically, a "port" is an outlet through which one device communicates with other devices. Ports can be divided into virtual ports and physical ports, where virtual ports refer to ports within a computer or within a switch router that are not visible. Such as 80 ports, 21 ports, 23 ports, etc. in a computer. The physical ports are also called interfaces, and are visible ports, RJ45 network ports of a computer backboard, RJ45 ports of a switch router hub and the like. The ports referred to in the present application are virtual ports.
The output unit 11 and the preset receiving unit 13 are two terminal devices or computer programs that establish port communication. After determining the output unit 11, a target receiving unit that needs to be port-connected may be selected from all preset receiving units 13 according to a selection instruction input by the user. Since the output unit 11 and each preset receiving unit 13 may be in the same electronic device, or may be in different electronic devices. Specifically, the terminal device or computer program providing the port service corresponds to one IP address, but the same terminal device or computer program may provide a plurality of services such as a database service, an FTP service, a Web service, and the like at the same time. The port number is used to distinguish between these different services provided by the same terminal device or computer program, and as is commonly known, the port number 21 indicates an FTP service, the port number 23 indicates a Telnet service port number 25 indicates an SMTP service, and so on. The port number is generally a 4-bit integer, and the port number cannot be repeated on the same computer, otherwise, a port number conflict occurs.
Therefore, the first preset identification information in the connection request may be an IP address of the port connection device to which the preset receiving unit 13 belongs, and the second target identification information may be any data information for distinguishing between different preset receiving units 13, such as a character string of a name and a number. In implementation, other data information which can be used for distinguishing different terminal devices or computer programs can be selected as the first preset identification information according to specific use requirements and application situations of users, and the first preset identification information is not limited further herein.
The port synchronization unit 12 is configured to forward the connection request to each preset receiving unit 13 in the port connection device corresponding to the first target identification information. Each preset receiving unit 13 is configured to determine whether the second preset identification information corresponding to each preset receiving unit 13 is the same as the second target identification information, where the preset receiving units 13 corresponding to the second preset identification information that is the same as the second target identification information are target receiving units, and all the preset receiving units 13 except the target receiving units do not respond to the connection request.
The target receiving unit is configured to select any unoccupied preset receiving port 131 as a target receiving port, and establish a port communication channel based on the target receiving port and the target receiving port.
In a specific implementation, the preset receiving ports 131 include an associated receiving port and a blank receiving port, the associated receiving port is a preset receiving port 131 associated with a preset network service type, the blank receiving port is a preset receiving port 131 not associated with the preset network service type, and the connection request further includes a target network service type.
The ports of an IP address are numbered by 16 bits, which can be up to 2 16 =65536 ports. Different ports are used to support different network services, and in general, the port numbers may be divided as follows:
0-1023: the port numbers are acknowledged, i.e. have been or will be acknowledged as being reserved for software, e.g. 80 ports for browsing of web pages, 20 and 21 for FTP requests etc. The web browsing and FTP requests are different preset web service types;
1024-65535: is a port number that is not commonly defined and the user can define the roles of these ports himself.
Specifically, the associated receiving port is the port defined with the preset network service type, and the blank receiving port is the port undefined with the preset network service type. The above-mentioned port dividing rule can be adjusted accordingly according to the actual use requirement of the user and the specific application scenario, for example, instead of 80 ports being used only for HTTP service, HTTP is not used only through 80 ports.
The target receiving unit is further configured to determine whether the association receiving port which is unoccupied and associated with the target network service type exists in the target receiving unit, where the target network service type is any one of the preset network service types. At this time, for different judgment results, the subsequent processing steps may be specifically divided into:
1. and if the associated receiving port which is unoccupied and associated with the target network service type exists in the target receiving unit, the target receiving unit is further used for selecting the corresponding associated receiving port as the target receiving port.
For example, the target network service type is a service, the preset receiving port 131 associated with the a service is X, and if the X port is not occupied at this time, the target receiving unit may select the X port as the target receiving port.
2. And if the unoccupied associated receiving ports associated with the target network service type do not exist in the target receiving unit, the target receiving unit is used for selecting any unoccupied blank receiving port to be associated with the target network service type, so as to obtain the target receiving port.
Since the blank receiving port is not associated with any preset network service type, i.e. the blank receiving port is not allocated with a certain service, the blank receiving port can be dynamically allocated or associated with any preset network service type. Corresponding to the above example, if the X port is already occupied, at this time, any blank receiving port, for example, a Y port, may be selected from all blank receiving ports of the target receiving unit, and the Y port is associated with the target network service type a service, so as to obtain the target receiving port.
3. If the target receiving unit does not have any unoccupied associated receiving port associated with the target network service type and/or the target receiving unit does not have any unoccupied blank receiving port, the target receiving unit is configured to send feedback information of connection failure to the port synchronization unit 12.
According to the port connection system provided by the application, the connection request comprising the first target identification information and the second target identification information corresponding to the target receiving unit is sent to the port synchronization unit, so that the target receiving unit meeting the requirements responds to the connection request to select any unoccupied preset receiving port as a target receiving port, and a port communication channel is established based on the target receiving port and the target receiving port, the process that the output equipment sequentially traverses each preset receiving port to judge whether the corresponding target receiving port exists in the target receiving unit is greatly reduced, and the port connection efficiency is greatly improved.

Step S202, the port synchronization unit forwards the connection request to each preset receiving unit in the port connection device corresponding to the first target identification information.
In step S203, each preset receiving unit determines whether the second preset identification information corresponding to each preset receiving unit is the same as the second target identification information, where the preset receiving unit corresponding to the second preset identification information that is the same as the second target identification information is a target receiving unit, and all the preset receiving units except the target receiving unit do not respond to the connection request.
In step S204, the target receiving unit selects any unoccupied preset receiving port as a target receiving port, and establishes a port communication channel based on the target receiving port and the target receiving port.
In specific implementation, the preset receiving ports include an associated receiving port and a blank receiving port, the associated receiving port is a preset receiving port associated with a preset network service type, the blank receiving port is a preset receiving port not associated with the preset network service type, and the connection request further includes a target network service type;
