Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. 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 application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In a communication device including an optical port, a presence register (Present) is generally provided, and the optical port is connected to the presence register through a circuit line, and when an optical module is inserted into or pulled out of the optical port, a level of the circuit line is changed, for example, the level of the circuit line is pulled down or pulled up. When the level of the circuit line changes, the value of the on-bit register connected with the circuit line changes. For example, when the level of the circuit line is pulled high, the value of the bit register is set to 1; when the level of this circuit line is pulled low, the value in the bit register is set to 0.
The inventors have found that in some embodiments, it is common to poll the bit register to read the value of the bit register, and determine whether the optical module is currently in place on the optical port according to the read value. Then comparing the results of the two polling, when the optical module is found to be changed from in-place to out-of-place, determining that the optical module on the optical port is pulled out, and performing a series of configuration on the optical port according to a configuration instruction set corresponding to the pulling-out action; when the optical module is found to be changed from no-in-place to in-place, if it is determined that the optical module is inserted into the optical port, the optical port needs to be configured in a series according to a configuration instruction set corresponding to the insertion motion.
However, the above-described method cannot sense the quick removal and reinsertion operation. For example, if it is detected that an optical module on a certain optical port is changed from no place to a place at a certain time, it is determined that an optical module is inserted into the optical port, and at this time, the communication device executes a series of configuration instruction sets corresponding to the insertion action to configure the optical port. If the optical module on the optical port is quickly pulled out and then inserted again in the process of executing the configuration instruction set, the optical module on the optical port may be inserted again when the communication device reads the value of the bit register again, that is, when the communication device reads the value of the bit register again, the value of the bit register changes from "not in bit" to "in bit". For the communication device, that is, the results of polling the presence register twice consecutively are all that the optical module is "in place", so that it can be determined that the optical module is not pulled out, and the configuration is continued according to the configuration instruction set corresponding to the insertion action, which causes a configuration error, and in a serious case, even may cause the port to be unusable, such as the port not UP.
Based on the above-mentioned drawbacks, embodiments of the present application provide a port configuration method and a communication device, which will be described in detail below.
As shown in fig. 1, which is a block schematic diagram of a communication device 10 provided in the embodiment of the present application, the communication device 10 includes a processor 11, a bit register 121, a plug flag (plug _ flag) register 122, and an optical port 13, where the optical port 13 is electrically connected to the bit register 121 through a circuit line, and the bit register 121 and the plug flag register 122 are electrically connected to the processor 11.
In this embodiment, the communication device 10 may set the value of the plug flag register 122 according to the level transition condition of the circuit line to indicate whether the optical module on the optical port 13 has been plugged out.
Optionally, in this embodiment, the communication device 10 may further include a programmable logic device 12, and the bit register 121 and the plug flag register 122 may be registers in the programmable logic device 12. The Programmable Logic Device 12 may be a Complex Programmable Logic Device (CPLD) or a Field-Programmable Gate Array (FPGA).
Fig. 2 is a schematic flowchart of a port configuration method applied to the communication device 10 shown in fig. 1 according to an embodiment of the present disclosure, and details of the port configuration method will be described below.
Step S201, setting the value of the plugging flag register 122 according to the level jump condition of the circuit line.
The step S201 may be implemented by the programmable logic device 12, and in detail, may be implemented by the following steps:
the programmable logic device 12 detects the circuit line at preset clock cycles at intervals, and sets the value of the plug flag register 122 to a preset value when detecting that the level of the circuit line jumps corresponding to the action of pulling out the optical module, so as to indicate that the optical module on the optical port 13 is pulled out.
In practice, the plug flag register 122 may be set according to the specific circuit between the optical port 13 and the bit register 121.
For example, when an optical module is inserted into the optical port 13 of the communication device 10, the level of the circuit line jumps from a low level to a high level; when the optical module is pulled out from the optical port 13 of the communication device 10, the level of the circuit line jumps from the high level to the low level. In view of the above situation, the programmable logic device 12 may set the value of the plug flag register 122 to the preset value, for example, 1, when detecting that the level of the circuit line jumps from the high level to the low level, so as to indicate that the optical module on the optical port 13 is unplugged.
For another example, when an optical module is inserted into the optical port 13 of the communication device 10, the level of the circuit line jumps from a high level to a low level; when the optical module is pulled out from the optical port 13 of the communication device 10, the level of the circuit line jumps from low level to high level. For this situation, when detecting that the level of the circuit line jumps from the low level to the high level, the programmable logic device 12 may set the value of the plug flag register 122 to the preset value, so as to indicate that the optical module on the optical port 13 is plugged out.
In some ways, the processor 11 polls the bit register 121 to determine whether the optical module is unplugged, which is actually implemented by a software module running in the processor 10.
In this embodiment, the programmable logic device 12 is implemented based on a hardware circuit, the operation speed is very fast, whether the level of the circuit line jumps or not can be detected by polling according to the clock cycle, and compared with polling by a software module, the clock cycle of the programmable logic device 12 is usually in the microsecond level, the time is very short, and the detection of the rapid optical module pulling-out action can be ensured.
The preset clock period may be one clock period, two clock periods, or multiple clock periods, and may be set according to the required detection accuracy, which is not limited in this embodiment.
Step S202, reading the value of the in-place register 121 and the value of the plug flag register 122 every preset time interval, determining whether an optical module is currently in place on the optical port 13 according to the value of the in-place register 121, and determining whether the optical module on the optical port 13 is pulled out according to the value of the plug flag register 122.
The preset time period may be flexibly set, for example, may be 1ms, 2ms, 10ms, and the like, which is not limited in this embodiment.
It should be understood that, in the present embodiment, there is no limitation on the order of reading the bit register 121 and the plug flag register 122, and there is no limitation on the order of determining the bit state of the optical module according to the value of the bit register 121 and determining whether the optical module is plugged out according to the value of the plug flag register 122.
Alternatively, in this embodiment, after reading the value of the bit register 121 and the value of the plug flag register 122, the processor 11 of the communication device 10 may determine whether the read value of the bit register 121 is the same as the last value of the bit register 121, and determine whether the read value of the plug flag register 122 is the same as the last value of the plug flag register 122.
If the judgment results are the same, determining whether an optical module is currently in place on the optical port according to the value of the in-place register 121, and determining whether the optical module on the optical port is pulled out according to the value of the plug flag register 122.
The reason is that, when neither the value of the bit register 121 nor the value of the insertion/extraction flag register 122 changes, it indicates that the optical module is not inserted or extracted in the period between the last detection and the current detection, and the previous arrangement can be maintained.
If at least one of the two determination results is different, that is, the value of the read in-place register 121 is different from the value of the last read in-place register 121, and/or the value of the read plug flag register 122 is different from the value of the last read plug flag register 122, it may be determined that an insertion or extraction action of the optical module occurs during the process, and the configuration of the optical port needs to be performed again. It is thus possible to determine what configuration should be performed according to the read value of the in-bit register 121 and the value of the plug flag register 122.
Step S203, when it is determined that there is an optical module currently in place on the optical port 13 and the optical module on the optical port 13 is not pulled out, configuring the optical port 13 according to a configuration instruction set corresponding to the insertion of the optical module.
In this case, it can be determined that the optical module is inserted, and the optical module is not pulled out too fast and then inserted, and further, the optical port 13 can be configured according to the configuration instruction set corresponding to the insertion of the optical module, for example, the related information of the optical module is acquired, and the operating mode, the communication rate, the full duplex/half duplex, and the like of the optical port 13 are configured.
Step S204, when it is determined that no optical module is currently in place on the optical port 13 and/or the optical module on the optical port 13 is pulled out, configuring the optical port 13 according to a configuration instruction set corresponding to the optical module pulling-out.
In this case, it is indicated that the optical module is removed, and the optical port 13 can be arranged according to the arrangement instruction set corresponding to the optical module removing operation.
In this embodiment, the programmable logic device 12 periodically detects a level jump condition of a circuit line, and sets the value of the plug flag register 122 according to the detection result, so that the value of the plug flag register 122 can be reset every time the optical module on the optical port 13 is determined to be pulled out according to the value of the plug flag register 122, so that the programmable logic device 12 can continue to set in the plug flag register 122 in a subsequent process, thereby recording whether the optical module is pulled out between the previous detection time and the current time in real time.
In practical applications, as shown in fig. 3, there may be multiple optical ports on the communication device 30, such as optical port 33, optical port 34, and optical port 35 shown in fig. 3. The bit register 321 may be electrically connected to the plurality of optical ports through the circuit lines, respectively, where the circuit lines may be communication buses. In this case, a plurality of flag bits are included in the bit register 321, and each flag bit corresponds to one optical port. Correspondingly, the plug flag register 322 may also include a plurality of flag bits, and each flag bit corresponds to one optical port.
In this embodiment, different flag bits of the bit register 321 and the plug flag register 322 may have different addresses, and a flag bit corresponding to any optical port may be determined according to the addresses.
When the communication device 30 includes a plurality of optical ports, the processor 31 of the communication device 30 may sequentially read the values of the flag bits corresponding to the plurality of optical ports from the bit register 321 and the plug flag register 322 at preset time intervals, and then determine the configuration to be executed on the optical port according to the read values.
A specific example will be given below in conjunction with fig. 4 to 7 to explain in detail a port configuration method applied to the communication device 30 shown in fig. 3.
It is assumed that in the communication device 30 shown in fig. 3, when an optical module is inserted into any optical port, a flag bit corresponding to the optical port in the bit register 321 is set to a high level; when an optical module on any optical port is pulled out, the flag bit corresponding to the optical port in the bit register 321 is set to a low level; when the programmable logic device 32 detects that the level of the circuit line jumps from the high level to the low level, the flag bit corresponding to the optical port in the plug flag register 322 is set to 1. Based on this, the port configuration method may include the following steps.
In step S401, the processor 31 of the communication device 30 executes the optical port polling task at preset intervals, and reads the value of the flag bit corresponding to the optical port 33 in the bit register 321 and the value of the flag bit corresponding to the optical port 33 in the plug flag register 322 each time the optical port polling task is executed.
Assume that the value corresponding to the optical port 33 read from the bit register last time is 1, and the value corresponding to the optical port 33 read from the plug flag register is 0. If the value corresponding to the optical port 33 read from the bit register at this time is 1 and the value corresponding to the optical port 33 read from the plug flag register is 0, steps S402 and S403 shown in fig. 4 may be executed.
In step S402, it is determined that the value of the flag bit corresponding to the optical port 33 in the read bit register 321 is the same as the value of the flag bit corresponding to the optical port 33 in the last read bit register 321, and the value of the flag bit corresponding to the optical port 33 in the read plug flag register 322 is the same as the value of the flag bit corresponding to the optical port 33 in the last read plug flag register 322, so that the optical port 33 is skipped, and step S403 is performed.
In step S403, the value of the flag bit corresponding to the optical port 34 in the bit register 321 and the value of the flag bit corresponding to the optical port 34 in the plug/unplug flag register 322 are read.
If the value corresponding to the optical port 33 read from the bit register at this time is 1 and the value corresponding to the optical port 33 read from the plug flag register is 1, steps S504 and S505 shown in fig. 5 may be executed.
In step S504, it is determined by judgment that the value of the flag bit corresponding to the optical port 33 in the read plug flag register 322 is different from the value of the flag bit corresponding to the optical port 33 in the last plug flag register 322.
Step S505 is to determine that the optical module is currently located on the optical port 33 according to the read value, and the optical module on the optical port 33 is pulled out, execute the configuration instruction set corresponding to the optical module pull-out to configure the optical port 33, set the flag position corresponding to the optical port 33 in the pull-out flag register 322 to 0, and execute step S403.
If the value corresponding to the optical port 33 read from the bit register at this time is 0 and the value corresponding to the optical port 33 read from the plug flag register is 1, steps S606 and S607 shown in fig. 6 may be executed.
In step S606, it is determined by determining that the value of the flag bit corresponding to the optical port 33 in the read bit register 321 is different from the value of the flag bit corresponding to the optical port 33 in the last read bit register 321, and the value of the flag bit corresponding to the optical port 33 in the read plug flag register 322 is different from the value of the flag bit corresponding to the optical port 33 in the last read plug flag register 322.
Step S607, determining that no optical module is currently located on the optical port 33 according to the read value, and the optical module on the optical port 33 is pulled out, executing a configuration instruction set corresponding to the optical module pull-out to configure the optical port 33, setting the flag position corresponding to the optical port 33 in the pull-out flag register 322 to be 0, and executing step S403.
When the value corresponding to the optical port 33 read from the bit register 321 at this time is 0 and the value corresponding to the optical port 33 read from the plug flag register 322 is 0, the procedure shown in fig. 7 may be executed.
In step S708, it is determined by the judgment that the value of the flag bit corresponding to the optical port 33 in the read bit register 321 is different from the value of the flag bit corresponding to the optical port 33 in the bit register 321 read last time.
Step S709, determining that no optical module is currently in place on the optical port 33 according to the read value, and no optical module pulling-out action occurs on the optical port 33, executing a configuration instruction set corresponding to optical module pulling-out to configure the optical port 33, and executing step S403.
In the present embodiment, the detection process for the light ports 34 and 35 is similar to the detection process for the light port 33. When the optical ports 33, 34 and 35 are polled, the optical port polling task is finished once, and the process is repeated when the next interval is reached.
In summary, the present application provides a port configuration method and a communication device, where the communication device includes an optical port, an in-place register and a plug flag register, and the in-place register is connected to the optical port through a circuit line. And setting the value of the plugging flag register according to the level jump condition of the circuit line. Determining whether an optical module is currently on the optical port according to the value of the on-position register, determining whether the optical module on the optical port is pulled out according to the value of the plugging flag register, and configuring the optical port according to a configuration instruction set corresponding to the insertion of the optical module when the current optical module on the optical port is determined to be on the position and the optical module on the optical port is not pulled out; and when determining that no optical module is in place at present on the optical port and/or the optical module on the optical port is pulled out, configuring the optical port according to a configuration instruction set corresponding to the pulling-out of the optical module. Thus, port configuration errors caused by the fact that the operation of instant extraction and insertion cannot be sensed can be avoided.
