Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for optimizing a communication network port, and a communication device.
Background
With the wireless update applications, the rate of partial access hotspots has exceeded 1Gbps, and communication Network ports (abbreviated as 2.5G/5G ports) based on 2.5G/5GBASE-T (Base-T is a Local Area Network (LAN) standard operating at bps, which is commonly referred to as fast ethernet) protocol have become increasingly popular because they can transmit signals along the ordinary hectometer CAT-5E/CAT-6 cable. Taking a 2.5G/5GBASE-T switch as an example, fig. 1 is a schematic diagram of a typical data transmission of the 2.5G/5GBASE-T switch, which is composed of a switch chip 11, a PHY (physical layer) chip 12, an isolation transformer 13, and an RJ45 network port 14, and is connected to an opposite-end docking device through a network cable. Specifically, when data is transmitted, a Media Access Control (MAC) protocol in the switch chip 11 determines in advance whether the data can be transmitted, and if the data can be transmitted, adds some Control information to the data, and finally transmits the data and the Control information to the PHY chip 12 in a specified format. The PHY chip 12, acting as a physical layer chip, primarily performs the conversion between data and serial data streams. The isolation transformer 13 is used for signal level coupling, can enhance signals, and enables a chip end inside the switch to be isolated from the outside, so that the anti-interference capability of the chip is greatly enhanced, and the chip is protected.
In the prior art, the signal quality of the received signal received by the 2.5G/5GBASE-T switch is improved mainly by a power back-off technique (i.e., corresponding power back-off is performed according to the power value read by the communication network port).
However, since the 2.5G/5G network port is affected by the wiring and environment of the conventional gigabit switch, the signal received by the 2.5G/5G network port is attenuated greatly, so that there is a significant risk in the operation of the 2.5G/5G network port in the hundreds of meters or more. The influence of the wiring and environment of the traditional gigabit switch on the 2.5G/5G network port specifically includes the following steps:
1) because the traditional gigabit switch has the condition that several or even dozens of network cables are bundled together in the wiring, each network cable is subjected to crosstalk of adjacent network cables, and the signal attenuation is large.
2) The wiring environments are different, and because the environment has been applied to a network cable with the length of more than 100 meters, in such an environment, transmission signals in the network cable increase along with the increase of the length of the network cable, and particularly, when the network cable exceeds 100 meters, a 2.5G/5G network port cannot be connected, so that the network port is downshifted to a gigabit mode or a hundred-megabyte mode for use, and the network throughput rate and the performance are greatly reduced.
3) The network cable brands of all environments are mixed, test parameters are good and bad, the inferior network cable has higher impedance under the same distance, and the signal attenuation is larger.
The power back-off technology is mainly used for enabling signals to work in a linear area through power attenuation so as to improve the signal quality, and received signals received by an exchanger in an ultra-long network cable transmission scene are already attenuated by the ultra-long network cable, so that the signal quality can be influenced if the attenuated signals are continuously attenuated. Therefore, for the ultra-long network cable transmission scenario, the power back-off is in a completely closed state, for example, in 5GBASE-T, if the network cable length is greater than 85, the power back-off function is closed, and in 2.5GBASE-T, if the network cable length is greater than 45, the power back-off function is closed. Therefore, for the ultra-long network cable scene, the power back-off technology has no effect of improving the signal quality.
Therefore, in such a long-line high-interference environment, how to improve the signal quality of the 2.5G/5G network port received signal is an urgent problem to be solved at present.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The execution main body of the optimization method for the communication network port provided by the embodiment of the application can be an optimization device for the communication network port or a switch for executing the optimization method for the communication network port. The optimization device of the communication network port may be a Central Processing Unit (CPU) in the communication device, or may be a control Unit or a functional module in the communication device.
The communication network port mentioned in the embodiment of the application is a network port or an electric port of communication equipment, and the communication equipment communicates with opposite-end docking equipment through a network cable connected with the communication network port. Illustratively, the communication portal includes, but is not limited to: 2.5G/5G network port, giga electric port, million electric port, ten thousand electric port, etc.
The communication port hereinafter will be described by taking "2.5G/5 GBASE-T port" as an example, and specifically by taking "port of 2.5G/5GBASE-T switch" as an example. It should be clear to those skilled in the art that the "2.5G/5 GBASE-T port" hereinafter may be replaced by a port or an electrical port of another communication device.
The basic principle of the technical scheme provided by the embodiment of the application is as follows: the purpose of adjusting the transmitting power of the communication network port is achieved by arranging the adjustable impedance module for the communication network port and adjusting the impedance value of the adjustable impedance module corresponding to the communication network port. Because the transmission power required by the attenuation degrees of different network cable lengths is different, the peak value of the signal received by the communication network port can represent the attenuation degree of the network cable connected with the communication network port to the signal. Therefore, the peak value of the received signal received by the communication network port is detected, and then the target impedance value of the adjustable impedance module corresponding to the communication network port and the peak value are determined according to the peak value, and since the target impedance value is the impedance value corresponding to the communication network port when the communication network port receives the received signal with the target signal strength in the signal attenuation scene corresponding to the peak value, if the impedance value of the adjustable impedance module is adjusted to the target impedance value, the transmitting power of the communication network port can be properly improved, the network port performance of the communication network port is further improved, and the signal quality of the long-distance transmission signal received by the communication network port is improved.
The adjustable impedance module mentioned in the embodiment of the present application may be a programmable impedance element or device such as a programmable resistor RDAC, and may also be an impedance circuit including a programmable resistor, and the impedance element, the device, or the circuit that can adjust the transmission power of the communication network port all belong to the protection scope of the present application, and are not limited herein.
It should be noted that in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
It should be noted that in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that the intended meanings are consistent when the differences are not emphasized.
The embodiment of the present application provides an optimization method for a communication network port, where the communication network port corresponds to an adjustable impedance module, and the adjustable impedance module is used to adjust the transmission power of the communication network port. As shown in fig. 2, the method comprises the steps of:
s201, detecting a peak value of a received signal received by a communication network port.
The peak value of the signal received by the communication network port can be represented as follows: the switch and the communication network port correspond to the signal attenuation degree of the network cable between the opposite end devices to the transmission signal, that is, the current signal attenuation scene can be determined based on the peak value of the received signal. For example, the signal transmission scenarios corresponding to the network cables with different lengths can be used as different signal attenuation scenarios, and are particularly suitable for ultra-long network cables (i.e., network cables with a length of one hundred meters or more than 100 meters, and generally, the signal attenuation degree of network cables with a length of more than 100 meters starts to be obvious). In an actual application scenario, the selection of the signal attenuation scenario may be set according to a specific usage scenario.
For example, when detecting a peak of a received signal received by the communication port, all peak information of the received signal received by the target communication port within a predetermined time period may be detected, so as to extract a value interval of the peak detected within the predetermined time period, or calculate an average peak of the peak detected within the predetermined time period, which is not limited herein.
In one example, the present application may detect the peak value of the received signal through an echo detection circuit, that is, detect the highest amplitude of the RX signal after attenuation through the longline. However, since the signal peak detected by the echo detection circuit is an analog signal, the detected peak analog signal needs to be converted into a digital signal and transmitted to the control module of the communication device for determination, the control module outputs the determined control signal to the high-precision digital potentiometer, and the impedance value of the adjustable impedance module is finely adjusted by the high-precision digital potentiometer, so that the transmission power of the communication network port is improved, and the output signal of the long network cable is further improved. The echo detection circuit can be arranged in the communication equipment, and can also be used as an independent detection device to be connected with the communication equipment for detection.
It should be noted that, after the communication device including the communication network port is powered on, a default reference impedance value is configured for the adjustable impedance module corresponding to the communication network port, where the reference impedance value is less than or equal to an impedance value corresponding to the communication network port when the communication network port receives a received signal of a target signal strength in a scene without signal attenuation.
S202, determining a target impedance value of the adjustable impedance module corresponding to the communication network port, which is matched with the peak value.
In the embodiment of the present application, the target impedance value of the adjustable impedance module corresponding to the communication network port is: and the communication network port receives the corresponding impedance value of the received signal of the target signal strength under the signal attenuation scene corresponding to the peak value. Illustratively, the target impedance value is an impedance value corresponding to a minimum transmission power when the communication network port receives a received signal of a target signal strength in a signal attenuation scenario corresponding to the peak value.
In one example, S202 described above can be implemented by the following process: acquiring a pre-stored impedance value list, and inquiring a target impedance value matched with the peak value and corresponding to an adjustable impedance module corresponding to the communication network port from the impedance value list; the impedance value list includes impedance values corresponding to the communication network port when receiving the received signal of the target signal strength under the signal attenuation scene corresponding to different peak values. For example, if the adjustable impedance module uses an RDAC resistor as an example, the impedance value list is an RDAC resistor value list, where the RDAC resistor value list includes a resistor value corresponding to a minimum transmission power when the communication network interface receives a received signal of a target signal strength in a signal attenuation scene corresponding to different peak values.
S203, adjusting the impedance value of the adjustable impedance module to be a target impedance value.
For example, taking the adjustable impedance module as an RDAC resistor, reducing the programmable RDAC resistor within a certain range can increase the reference current of the RDAC, thereby increasing the amplitude of the analog signal from the RDAC, and increasing the transmission power of the corresponding communication network port, so as to improve the signal quality of the received signal received by the switch after attenuation by the ultra-long network cable.
Optionally, after the peak value of the received signal received by the communication network port is detected, in order to improve the processing efficiency of the communication device, the peak value of the signal received by all the communication network ports of the communication device may be determined, so as to screen out the communication network ports with long-distance communication from all the communication network ports, and perform a transmission power adjustment procedure, that is, an impedance value adjustment procedure.
Specifically, the method further includes the following steps after S201:
a1, determining whether the peak value of the received signal is greater than or equal to a predetermined peak value threshold.
A2, if the peak value is larger than the preset peak value threshold value, executing S201 and S202; and if the peak value is less than or equal to the preset peak value threshold value, adjusting the impedance value of the adjustable impedance module to be the reference impedance value.
For example, the peak value of the signal can represent the signal attenuation degree of the network cable between the opposite-end device and the switch corresponding to the communication network port receiving the signal when the signal is transmitted, for example, the longer the network cable is, the greater the signal attenuation is for the transmission of the network cable, the smaller the amplitude peak value of the signal is, and therefore, the peak value is used as the judgment reference in the present application to determine whether to adjust the impedance value of the adjustable impedance module.
For example, the communication port in the present application is exemplified by "2.5G/5 GBASE-T port", and specifically, is exemplified by "port of 2.5G/5GBASE-T switch".
As shown in fig. 3, the present application screens out a communication port where long-distance communication exists by setting a predetermined peak threshold. Specifically, taking the adjustable impedance module as an RDAC resistor as an example, after the switch and the remote docking device are powered on, the switch may configure a default RDAC reference resistance value for the RDAC resistor in the RDAC module, detect a peak value of a received signal received by a network port of the switch after the switch is initialized successfully, determine that the received signal is a strong attenuation signal if it is determined that the peak value of the received signal is greater than or equal to a predetermined peak value threshold, perform an RDAC resistance value adjustment procedure on the RDAC resistor corresponding to the network port receiving the received signal, determine a target resistance value matched with the peak value for the RDAC resistor, and adjust the resistance value of the RDAC resistor to the target resistance value to improve the transmission power of the network port; and if the peak value of the received signal is judged to be smaller than the preset peak value threshold value, the received signal is judged to be a weak attenuation signal, the resistance value of the RDAC resistor corresponding to the network port for receiving the received signal is set to be a default RDAC reference resistance value through a Complex Programmable Logic Device (CPLD), and the switch normally works after the setting is finished.
In addition, it should be noted that the target signal strength mentioned in the present application may be a signal strength set by a user, or may be a signal strength of a signal received by the switch at an optimal transmission power in a scenario without signal attenuation.
