Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the technical solutions of the present specification will be clearly and completely described below with reference to specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present specification with reference to the accompanying drawings.
Fig. 1 is a flow chart of a network data transmission method provided in the present specification, which specifically includes the following steps:
s100: first network data to be received is determined, and data parameters of the first network data are determined, wherein the data parameters comprise at least one of transmission rate and data length.
The embodiments of the present specification provide a transmission method of network data, and an execution process of the transmission method of network data may be executed by a port for transmitting data.
The method is different from the prior art that when data is transmitted, parameters such as the rate of network data to be transmitted are not controlled, so that under the condition that the equipment encounters capacity exhaustion attack, the attack behavior can be solved only by restarting the equipment and the like, and the equipment cannot transmit information before restarting.
The present disclosure provides a new method for transmitting network data, after receiving first network data, determining a data parameter of the first network data, and when the data transmission is matched with port configuration information of the port, receiving the first network data again, and when the transmission rate of the first network data is too fast and/or the data length of the first network data is too long, storing the first network data in a storage unit, and when the transmission rate and the data length of the first network data are adjusted by the storage unit, then transmitting the first network data to the port. Therefore, the network data received by the port for receiving the first network data can not occupy the network resources of other ports of the device, and the data transmission efficiency is ensured.
Based on the above brief description of the transmission method of the network data, it can be seen that the transmission method of the network data needs to determine whether to directly receive the first network data based on the data parameters of the first network data. Thus, the terminal may determine the first network data.
Specifically, as previously described, each port has its corresponding transmission channel. The data sender may then transmit the first network data to the port via the transmission channel.
The port may then determine the first network data to be received.
The port may then determine a data length of the first network data. Alternatively, the port may determine the transmission rate of the first network data.
Finally, the port may use at least one of the determined data length and the determined transmission rate as a data parameter of the first network data.
S102: and determining preset port configuration information, and judging whether the data parameters and the port configuration information are matched. If yes, go to step S104. If not, go to step S106.
In one or more embodiments provided herein, the port has its port configuration information preset. The port configuration information may be a maximum transmission rate of the port, or a maximum data length that the port can transmit. Therefore, after determining the data parameter of the first network data, it may be determined whether the data parameter of the first network data matches the port.
Specifically, if the port configuration information is the maximum transmission rate of the port, the port may determine whether the transmission rate of the first network data is not greater than the maximum transmission rate of the port. If so, the port may receive the first network data. If not, the port can store the first network data in advance.
If the port configuration information is the maximum length of network data that the port can transmit, the port can determine whether the data length of the first network data is not greater than the maximum length. If so, the port may receive the first network data. If not, the port can store the first network data in advance.
Of course, the port configuration information may also be a device identifier of a data sender of the network data, etc. The data type corresponding to the port configuration information can be set according to the requirement, and the specification does not limit the data type.
It should be noted that, the port may also match the data transmission rate and the data transmission rate, and if any of the judging results is negative, the port may determine that the matching result is not matching. In particular, how the matching result is determined may be set according to needs, and this specification does not limit this.
S104: the first network data is received.
In one or more embodiments provided herein, upon determining that the data parameters of the first network data and the port configuration information of the port match, the port may receive the first network data and process the first network data after the receiving.
S106: and forwarding the first network data to a storage unit, and receiving target data sent by the storage unit, wherein the target data is generated by the storage unit after the first network data is adjusted according to the port configuration information.
In one or more embodiments provided herein, when the data parameter of the first network data and the port configuration information of the port do not match, the port may store the first network data in the storage unit, and the storage unit adjusts the first network data and then resends the first network data to the port.
Specifically, the storage unit is used for storing network data with unmatched data parameters and port configuration information, so as to avoid the abnormal loss of key data caused by port blocking due to sudden data transmission. As shown in fig. 2.
Fig. 2 is a schematic flow chart of a data transmission method provided in the present disclosure. The data sender and the port are connected through a network, and under the condition that the data parameters are not matched with the port configuration information, the port can not receive the first network data, but forward the first network data to the storage unit.
The storage unit can receive the first network data, and adjust the transmission rate or the data length of the first network data according to the transmission rate and the data length corresponding to the port configuration information so as to obtain target data with data parameters matched with the port configuration information.
The memory unit may then transfer the target data to the port.
The port may receive the target data sent by the storage unit.
Based on the transmission method of the network data shown in fig. 1, after receiving the first network data, determining the data parameters of the first network data, and when the data transmission is matched with the port configuration information of the port, receiving the first network data, and when the transmission rate of the first network data is too fast and/or the data length of the first network data is too long, storing the first network data in a storage unit, and after the transmission rate and the data length of the first network data are adjusted by the storage unit, sending the first network data to the port. Therefore, the network data received by the port for receiving the first network data can not occupy the network resources of other ports of the device, and the data transmission efficiency is ensured.
In addition, in order to avoid the situation that the third party device initiates the network attack through the port, the port may also store an address of a designated device that can communicate with the port. When the first network data is received, whether the data sender of the first network data is trusted or not can be judged, and the first network data is received again under the condition of the credibility. The address may be a network address or a physical address.
Specifically, in the case of receiving the first network data, the port may determine an address of a target device that transmits the first network device.
Then, the port can judge whether the address of the target device exists in the addresses of the designated devices according to the address of the target device and the addresses corresponding to the designated devices stored in advance by the port. Wherein each designated device is a trusted device for that port. The port may determine that the target device that sent the first network data is a trusted device if present and an untrusted device if not present.
The port may then receive the first network data if it is determined that the target device is authentic.
And in the event that the target device is not trusted, the port may discard the first network data as untrusted data.
Further, for the data transmission process, in order to ensure data security in the data transmission process, the data transmitted between the two ports or the two devices may include valid data or invalid data. Therefore, after receiving the first network data, the port can also determine whether the first network data is valid, and when the first network data is valid, the port can receive the first network data again.
In particular, in general, it may be determined for a first identification that is predetermined in advance for two ports that transmit network data, as to how to distinguish whether the network data is valid. Thus, after receiving the first network data, the server may determine a first identifier carried in the first network data. The first identifier may be a first digit of the network data, or may be a result obtained by performing hash operation on the first network data, where the first identifier may be specifically determined how to be set as required, which is not limited in this specification.
The port can then determine whether the first network data is valid data according to the first identifier.
If so, the port may receive the first network data. If not, the port may discard the first network data.
Further, in this specification, the network data transmitted by the port may have a priority corresponding to the network data, so as to avoid the situation that the port is occupied by the data with higher priority for a long time, and the data with lower priority cannot be transmitted, and the port may be provided with channels corresponding to different priorities. That is, in this specification, network data of different priorities is transmitted on different channels, which correspond to different network resources. For example, the bandwidth resource corresponding to the network data with the priority of 1 is 1k-10kbit/s, and the bandwidth resource corresponding to the network data with the priority of 2 is 10k-100kbit/s.
In addition, when the port transmits data, the second network data can be transmitted in the channel corresponding to the corresponding priority based on the priority of the network data.
Specifically, the port may determine second network data to be transmitted and determine a target priority of the second network data.
The port may then determine a channel for transmitting the network data of the target priority and add the second network data to a message queue corresponding to the channel.
Finally, the port can transmit the second network data according to the transmission rate and the data length corresponding to the port configuration information based on the message queue. The first network data is the network data received by the interface, and the second network data is the network data which needs to be sent by the interface.
Further, in the process of transmitting data through the port, the port abnormality may occur, so that the data transmitted through the port does not conform to the port configuration information. Therefore, in the present application, the port may be further connected with a calibration unit to determine, in real time, a data parameter of the network data transmitted by the port, so as to avoid the occurrence of the above situation based on the data parameter.
Specifically, the port is connected to a calibration unit for measuring the transmission rate and the data length of the second network data. As shown in fig. 3.
Fig. 3 is a schematic flow chart of a data transmission method provided in the present disclosure. The data receiver is connected with the port through a network, and the port is connected with the calibration unit. The calibration unit may measure a data parameter of the second network data when the port transmits the second network data to the data receiver.
Then, the port can receive the measurement rate and the measurement length obtained after the calibration unit measures the second network data, and determine whether the measurement rate and the measurement length match the port configuration information.
If so, the port may continue to transmit the second network data.
If not, the port may send a prompt to the user. The prompt message is used for prompting that the port has an abnormality. The user may be a user transmitting data using the port.
In addition, in this specification, the configuration information of the port may also be set for a user who uses the port to transmit data.
Specifically, the port is connected to a setting unit, which can determine a port setting parameter according to an operation performed by a user.
The port may then receive the port setting parameters determined by the setting unit according to the user operation. Wherein the port setting parameter may include at least one of an identification of a designated device in communication with the port, a maximum transmission rate of the port, and a maximum length of network data that the port may transmit.
The port may be configured according to the received port setup parameters.
Further, in the present specification, when the data parameter of the first network data does not match the configuration information of the port, the user may also adjust the configuration information of the port based on the data parameter of the first network data.
Specifically, the port is connected to the setting unit. The port may then receive the pending transmission rate and the pending data length determined by the setting unit according to the user operation. And configuring the port according to the pending transmission rate and the pending data length, and determining pending configuration information of the port.
The port is also connected to a calibration unit for measuring the transmission rate and data length of the first network data.
The port may then receive the data parameters of the first network data determined by the calibration unit and determine whether the pending configuration information matches the data parameters of the first network data.
If so, the port may continue to receive the first network data.
If not, the port may send the determined data parameter of the first network data to the setting unit.
The setting unit can receive the data parameters of the first network data sent by the port, and prompt the user that the undetermined transmission rate and the undetermined data length are abnormal according to the data parameters, so that the user adjusts the undetermined transmission rate and the undetermined data length according to the data parameters of the first network data.
Then, the setting unit may re-determine the port setting information in response to an input operation of the user, and transmit the re-determined port setting information to the port.
The port reconfigures the port according to the re-received port setting information.
The port in the present specification may be a port for transmitting data by a physical device, and may be connected to each unit to achieve the functions of ensuring data transmission efficiency and avoiding network attacks as described above. The port may further include a transmission unit for transmitting data, and each unit may be built in to realize the functions of ensuring data transmission efficiency. As shown in fig. 4.
Fig. 4 is a schematic structural diagram of a port provided in the present specification. In the figure, the four units of the storage unit, the transmission unit, the setting unit and the calibration unit form a port. The port can receive the network data sent by the data sender and can also be used as the data sender to send the network data to the data receiver. The port may then receive the port setting parameters sent by the setting unit and configure the transmission unit according to the port setting parameters. The transmission unit may receive the first network data transmitted by the data transmitter, determine a data parameter of the first network data, and determine whether the data parameter and the configuration information of the transmission unit are matched. And if so, receiving the first network data. If not, the first network data is forwarded to the storage unit.
The storage unit receives the first network data, adjusts the data parameters of the first network data, obtains target data and sends the target data to the transmission unit.
When the transmission unit transmits the second network data as the data transmission direction, the calibration module may determine a measurement parameter of the second network data, and transmit the second network data based on a result of whether the measurement parameter matches configuration information of the transmission unit itself.
It should be noted that the connection relation between the above units is only illustrative, the calibration unit may also be used to measure the data parameter of the first network data, and the calibration unit may also be connected to the setting unit, etc. In particular, how the units in the port are connected may be set according to needs, which is not limited in this specification.

In the 90 s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable Gate Array, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented by using "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before the compiling is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but not just one of the hdds, but a plurality of kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), lava, lola, myHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
The system, apparatus, module or unit set forth in the above embodiments may be implemented in particular by a computer chip or entity, or by a product having a certain function.
