The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses an interface rate adjusting method, the flow of which is shown in figure 1, comprising the following steps:
step S11, acquiring the current system traffic and the current interface rate;
firstly, the current system traffic and the current interface rate are detected. The current interface rate may be a preset default rate.
Further, the current interface rate may also be a preset rate set according to the approximate range of the traffic volume after the system detects the traffic volume for the first time, so as to ensure that the subsequent processing process can be adjusted on the basis of the preset rate.
Step S12, judging whether the current system traffic is matched with the current interface rate according to the preset corresponding relation between the traffic and the interface rate;
and step S13, when the interface rate corresponding to the current system traffic is judged not to match the current interface rate, adjusting the current interface rate.
The preset corresponding relationship between the traffic volume and the interface rate in this embodiment may be in various forms, where the corresponding relationship may be that a certain traffic volume value or a traffic volume interval corresponds to a certain interface rate value one to one, the larger the traffic volume value or the traffic volume interval in which the traffic volume value or the traffic volume interval is located is, the larger the corresponding interface rate value is, or the larger the traffic volume is, the different traffic intervals may be divided according to the size of the traffic volume, the interface rate is set to different rate levels according to the size, a certain level of the interface rate corresponds to a certain traffic volume interval of the system traffic volume, and the larger the interface rate corresponding to the interval with the higher traffic volume is, in a specific judgment process, it is only necessary to judge whether the traffic interval to which the traffic volume of the current system belongs corresponds to the rate level to which the.
The specific adjustment process comprises the following steps:
if the interface rate corresponding to the current system traffic is higher than the current interface rate, increasing the current interface rate;
and if the interface rate corresponding to the current system traffic is judged to be lower than the current interface rate according to the preset corresponding relation between the traffic and the interface rate, reducing the current interface rate.
Further, the method also comprises the following steps:
and step S14, when the interface rate corresponding to the current system traffic is judged to be matched with the current interface rate, keeping the current interface rate.
And when the interface rate is matched with the current interface rate, maintaining the current interface rate to receive and transmit the traffic.
In the interface rate adjusting method disclosed by the invention, the current system traffic and the current interface rate are detected, whether the current system traffic corresponds to the current interface rate is judged according to the preset corresponding relation, and then the non-corresponding interface rate is adjusted to adapt to the current system traffic, so that the purpose that the interface rate can be adjusted according to the size of the current traffic is realized, the resource waste caused by transmitting smaller data by adopting higher bandwidth is avoided, and the energy consumption of the system is reduced, for example, when the high-speed serial port rate is changed from high bandwidth to low bandwidth, the power consumption of each channel can be reduced to 10-50% of the original power consumption, for example, when the rate is reduced from 10Gbit/s to 2.5Gbit/s, the power consumption is reduced by 85%, and meanwhile, the bandwidth utilization rate is improved.
Further, the above embodiment further includes:
step S15, determining that the system traffic at the next time of the current time is the current system traffic, determining that the adjusted interface rate is the current interface rate, and returning to execute step S11.
In this embodiment, the adjustment process of the interface rate is determined as a real-time and repeated process through the loop step, so that it is ensured that the rate of the interface can be adjusted in real time according to the size of the traffic in the working process of the whole interface, and the interface rate can better adapt to the size of the traffic or be matched with the size of the traffic, thereby further reducing the power consumption of the system and improving the utilization rate of the system.
When the preset corresponding relation between the traffic volume and the interface rate is as follows: fig. 2 shows a flow of another interface rate adjustment method disclosed in the embodiment of the present invention when a certain level of the interface rate corresponds to a certain traffic interval of the system traffic and the interface rate corresponding to the interval with higher traffic is higher, the flow includes:
step S21, acquiring the current system traffic and the current interface rate;
step S22, judging whether the current system traffic is 0, if yes, executing step S29, and if not, executing step S23;
if the current system traffic is 0, it indicates that data transmission and reception are not needed.
Step S23, judging whether the current system traffic is matched with the current interface rate according to the preset corresponding relation between the traffic and the interface rate, if so, executing step S28, and if not, executing step S24;
in this embodiment, matching means that the current system traffic is in the service interval corresponding to the current interface rate level, and the current system traffic is inevitably not less than the lower limit of the service interval and not more than the upper limit of the service interval.
Step S24, judging whether the current system traffic is larger than the upper limit of the traffic interval corresponding to the current interface rate grade, if so, executing step S25, otherwise, executing step S26;
step S25, adjusting the interface rate upwards by one level, and returning to execute step S22;
step S26, judging whether the current system traffic is less than the lower limit of the traffic interval corresponding to the current interface rate grade, if yes, executing step S27, if no, returning to step S21;
if the value is not greater than the upper limit or less than the lower limit, but is still determined to be not matched, an error occurs in the available system traffic or the interface rate, and at this time, the step S21 is returned to perform the re-acquisition for determination.
Step S27, adjusting the interface rate downward by one level, and returning to execute step S22;
step S28, keeping the current interface speed;
and step S29, turning off the high-speed interface.
After the high-speed interface is turned off, if the traffic at the next moment is not 0, the high-speed interface can be turned on again, and the work of receiving the traffic is continuously executed.
In the embodiment of the present invention, the execution sequence of the steps such as S24 and S26 may be adjusted according to a specific application scenario, which is not limited herein.
In this embodiment, the condition of turning off the high-speed interface is not limited to that the obtained traffic of the current system is 0, and when a board corresponding to the high-speed interface in the base station is in a backup state or a plurality of baseband service board group resource pools in the base station have no high-speed interface linked with an RE (radio equipment), the high-speed interface may be turned off as well.
In this embodiment, it is not limited to perform the interface rate adjustment step by using the above steps, and other manners may be also used, for example, determining a traffic interval corresponding to the current system traffic and an interface rate corresponding to the traffic interval, and directly adjusting the current interface rate to the interface rate corresponding to the traffic interval. If the current traffic is larger than the upper limit of the traffic interval corresponding to the current interface rate level, the difference between the current system traffic and the upper limit of the traffic interval corresponding to the current interface rate level can be obtained, and the difference can be divided by the range of the traffic contained in the traffic interval, so that several interface rate levels are determined to be adjusted upwards, the interface rate is directly adjusted to the corresponding level, the adjustment rate is accelerated, and the system performance is improved.
The interface rate adjusting method disclosed by the above embodiment of the invention can be applied to a serial interface and can also be applied to a parallel interface. No matter which interface is applied, the principle of realizing the rate adjustment of the interface is the same, and the rate adjustment is changed in the specific implementation process according to the characteristics of the parallel interface and the serial interface. When parallel data is transmitted, a sending device transmits a plurality of data bits to be transmitted to a receiving device through corresponding data lines, and the receiving device can directly use the received data without any transformation. During serial data transmission, the sending device needs to convert data into a serial mode through the parallel-to-serial conversion circuit and then send the serial mode to the receiving device through the transmission line bit by bit, and the receiving device needs to convert the received data into a parallel mode again from the serial mode through the serial-to-parallel conversion circuit.
Therefore, when the method is applied to the parallel interface, the purpose of adjusting the interface rate of the current interface can be achieved by directly adjusting the clock frequency of the bus clock of the parallel interface controller in the parallel interface.
When applied to a serial interface, the adjustment process in the above embodiment may be:
and adjusting the reference clock frequency of the serial-parallel conversion circuit and/or adjusting the internal phase-locked loop frequency multiplication coefficient of the serial-parallel conversion circuit to adjust the current interface rate.
Fig. 3 is a schematic diagram of a relationship between a reference clock in a serial-parallel conversion circuit and a high-speed serial port, and it can be seen from the diagram that the reference clock is input to a clock phase-locked loop PLL of the serial-parallel conversion circuit, and under other conditions, when the frequency of the reference clock is changed, the output frequency of the PLL in the serial-parallel conversion circuit is correspondingly adjusted, and the data rate of the output of the high-speed serial port is consistent with the output frequency of the PLL in the serial-parallel conversion circuit, so that the adjustment of the frequency of the reference clock can achieve the corresponding adjustment of the rate of the high-speed serial port.
Specifically, a process of adjusting the reference clock of the serial-to-parallel conversion circuit to adjust the interface rate is shown in fig. 4, and includes:
step S41, sending configuration information to a clock generating circuit;
specifically, the configuration information may be sent to the clock generation circuit through a clock adjustment line.
And step S42, the clock generating circuit adjusts the reference clock of the serial-parallel conversion circuit according to the configuration information.
In the speed adjustment of each single-board high-speed serial port inside the base station, an OM (Object Management) link is usually used for implementation.
Similarly, when the reference clock is not changed, the frequency multiplication coefficient of the PLL inside the serial-parallel conversion circuit, such as the prescaler R, the feedback frequency divider N, and the output configuration frequency divider M in fig. 3, is changed, and the output frequency of the PLL can also be changed.
And similarly, a mode of simultaneously adjusting a reference clock inside the serial-parallel conversion circuit and a frequency multiplication coefficient of the PLL can be adopted, so that the data rate output by the high-speed serial port can meet the requirement matched with the current traffic more quickly.
The corresponding relation between the interface rate grade and the specific reference clock frequency and the frequency multiplication coefficient can be pre-established, when the interface rate grade needs to be adjusted, which value the reference clock frequency needs to be adjusted to and which value the frequency multiplication coefficient needs to be adjusted to can be found visually through the corresponding relation, so that the rate of the adjusting process is increased, the adjusting time is reduced, and the performance of the system is improved.
