Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

In one embodiment, as shown in fig. 1, a method for data communication of a switch is provided, and the method is applied to the switch for example, and the optical module is inserted into the switch, and includes the following steps:

and 102, when the optical module is detected to be in place normally, controlling the optical module to enter a low power consumption state.

The Optical Module (Optical Module) is used as an important component in Optical fiber communication and is an optoelectronic device for realizing photoelectric conversion and electro-Optical conversion functions, and the Optical Module can realize interconnection of a network card and a switch and interconnection of switches at different levels.

Specifically, when the optical module is inserted into the switch, the switch detects whether the optical module is normally in place, that is, the optical module is inserted into the correct position in the switch and is normally connected, when the switch detects that the optical module is normally in place, the optical module is controlled to directly enter a low power consumption state, and when the optical module is inserted into the switch, the optical module enters a starting state and then enters the low power consumption state after a period of time, so that when the switch detects that the optical module is normally in place, the optical module is controlled to directly enter the low power consumption state.

In one embodiment, step 102 includes: when the optical module is detected to be normally in place, the optical module is controlled to enter a low-power-consumption state through the low-power-consumption state control pin.

The switch control optical module directly enters the low power consumption state through the low power consumption state control pin control, the starting state and the low power consumption state of the optical module are connected with the switch through corresponding pins, and the switch can control the optical module to enter the low power consumption state (moduleLowPwr) through the low power consumption state control pin corresponding to the low power consumption state. The optical module enters a low power consumption state, and in the state, the optical module cannot work normally, namely, the optical module cannot send any signal to the switch at the moment, and any data communication cannot be carried out between the optical module and the switch.

And 104, when the receiving switch of the PHY chip is detected to be in an unopened state, controlling the optical module to release the low-power-consumption state, and enabling the optical module to be normally powered on, wherein the receiving switch is used for receiving a receiving signal sent by the optical module.

When the optical module enters a low power consumption state and cannot normally work, the switch needs to detect the state corresponding to the receiving switch of the PHY chip (Port Physical Layer, the state corresponding to the receiving switch of the port physical layer) can be used for determining whether to release the low power consumption state of the optical module, so that if the state corresponding to the receiving switch of the PHY chip is on, the low power consumption state of the optical module is released, the optical module can normally work, the switch receives a signal sent by the optical module through the receiving switch of the PHY chip, and if the quality of the signal sent by the optical module is poor, abnormal connection between the switch and the optical module can be caused, and therefore, when the optical module cannot normally work, the switch detects the state corresponding to the receiving switch of the PHY chip.

The receiving switch is used for receiving a receiving signal sent by the optical module in the switch, and data communication between the switch and the optical module can be controlled through the state of the receiving switch. Specifically, when the switch detects that the state corresponding to the receiving switch of the PHY chip is not turned on, it is indicated that signal transmission is not performed between the switch and the optical module, so that the low-power consumption state of the optical module can be relieved, and the optical module is powered on normally.

In one embodiment, step 104 includes: and when the receiving switch of the PHY chip is detected to be in an on state, the receiving switch of the PHY chip is turned off.

If the switch detects that the state corresponding to the receiving switch of the PHY chip is in the on state, it indicates that the switch and the optical module can perform signal transmission through the receiving switch of the PHY chip, so that if the low-power consumption state of the optical module is released at this time, the switch is easily affected by the signal quality of the optical module, and therefore the receiving switch of the PHY chip that has been turned on needs to be turned off, specifically, when the switch detects that the receiving switch of the PHY chip is in the on state, the receiving switch of the PHY chip can be turned off temporarily.

And step 106, when the optical module enters the module in-place state, acquiring the data path state of the optical module.

After the switch releases the low power consumption state of the optical module, the optical module is normally powered on, when the optical module is powered on successfully, the optical module can enter a module in-place state, and when the optical module enters the module in-place state, the optical module is ready for working, but the optical module does not represent that the optical module can stably perform data transmission even after entering the module in-place state, but only represents that all parts of the optical module are powered on normally, but for a data path, a laser, a PD chip and a DSP chip are powered on only after the optical module performs the module in-place state, so that the output signal quality cannot be ensured in the initial power-on stage of the optical module, and therefore, the signal quality of the data path is self-checked inside the optical module, and the corresponding data path state is generated.

Further, the switch can determine whether the optical module enters a formal readiness state through the data path state generated by the optical module, and at this time, the signal quality output by the optical module is guaranteed. The data path state is a state of a data path embodying the optical module and can be obtained through a state of a data path state machine.

And step 108, when the data path state indicates that the optical module enters the data path activation state, the control PHY chip opens the receiving switch so that data communication is carried out between the optical module and the switch.

Specifically, when the data path state read by the switch indicates that the optical module enters the data path activation state, it is indicated that the optical module is ready at the moment, and at the moment, the signal quality output by the optical module is guaranteed, so that a receiving switch of the PHY chip can be turned on, and data communication can be performed between the optical module and the switch, and when the signal quality of the optical module reaches the standard, the signal receiving of the PHY chip is turned on, so that the problem of abnormal connection between the optical module and the switch can be effectively solved, and the signal quality output by the optical module is improved.

In the switch data communication method, when the optical module is inserted into the switch, whether the optical module is normally in place is detected, when the optical module is detected to be normally in place, the optical module is controlled to enter a low power consumption state, at the moment, the optical module cannot normally work, whether a receiving switch of the PHY chip is started is detected, when the receiving switch of the PHY chip is not started, the switch cannot receive a receiving signal sent by the optical module, at the moment, the low power consumption state of the optical module is relieved, the optical module is normally electrified to work, when the quality of the signal output by the optical module is optimal, the receiving chip of the PHY chip is opened, data transmission between the optical module and the switch is realized, abnormal connection between the switch and the optical module can be effectively solved, and abnormal connection rate between the switch and the optical module is reduced.

In one embodiment, when detecting that the optical module is in place, before controlling the optical module to enter the low power consumption state, the method further comprises: detecting whether the optical module is normally in place, executing a step of controlling the optical module to enter a low power consumption state when the optical module is detected to be normally in place, and pulling out the optical module from the switch and reinserting the optical module into the switch when the optical module is detected to be abnormally in place.

However, there is a possibility that the optical module is inserted into a position of the switch, and the optical module is inserted into a wrong position, loose insertion of the optical module, or other problems. Specifically, whether the optical module is inserted normally or not is detected, when the optical module is detected to be normally in place, a step of controlling the optical module to enter a low power consumption state can be executed, otherwise, when the detected optical module is abnormally in place, a step of controlling the optical module to enter the low power consumption state cannot be executed, and the optical module needs to be pulled out of the switch and reinserted to a correct position in the switch. Wherein, abnormal bit includes error of insertion position of optical module, loose insertion of optical module, or quality problem of optical module.

In one embodiment, when detecting that the receiving switch of the PHY chip is in an unopened state, controlling the optical module to release the low power consumption state, and performing normal power-up of the optical module includes: and acquiring a switch state corresponding to a receiving switch of the PHY chip, judging whether the receiving switch is started to receive a receiving signal sent by the optical module according to the switch state, and controlling the optical module to release a low-power consumption state when the receiving switch is detected to be in a non-started state, wherein the optical module is powered on normally, and then works normally after the power on is successful.

Specifically, the switch detects a switch state corresponding to a receiving switch of the PHY chip, where the receiving switch of the PHY chip is used to receive a receiving signal sent by the optical module, and the switch can determine whether the PHY chip starts to receive the receiving signal sent by the optical module according to the switch state of the receiving switch of the PHY chip, so as to determine whether the low power consumption state of the optical module can be released. Further, when the switch state of the receiving switch of the PHY chip indicates that the PHY does not start receiving signals sent by the optical module, the optical module can be controlled to release the low-power-consumption state, and even if the signal quality output by the optical module is relatively poor at present, the switch is not affected, so that the low-power-consumption state of the optical module can be released, the optical module can be powered on normally, and the optical module can work normally after the power-on is successful.

In one embodiment, when the optical module enters a module in-place state, acquiring the data path state of the optical module includes: and after the optical module is powered on, the optical module enters a module in-place state, and the data path state of marking the quality of the output signal in the optical module is identified.

Specifically, when the switch releases the low power consumption state of the optical module, the optical module is powered on normally, after the power on is successful, the optical module can work normally, and the state corresponding to the optical module is the module in-place state at this time, but the optical module enters the module in-place state, and the optical module is not represented to be capable of transmitting data stably, but only represents that all parts of the optical module are powered on normally, especially for a data path, a laser, a PD chip and a DSP chip are powered on only after the optical module enters the module in-place state, and the output signal quality cannot be ensured in the early stage of power on, so that the signal quality of the data path is self-checked inside the optical module, and the corresponding data path state is generated.

The data path state corresponding to the optical module may be identified by identifying the data path state in the optical module, where the data path state is marked with the output signal quality, that is, each data path state is marked with a corresponding label in the optical module, and the label stored in the optical module is searched for the data path state corresponding to the output signal quality.

Specifically, since the optical module stores the data path state into the corresponding register and associates the corresponding tag with the register, the switch may access the register marked as the data path by the tag in the optical module through the I2C path of the optical module, and further, acquire the data path state corresponding to the optical module from the accessed register. The data path state here may represent all states corresponding to the data path of the optical module at this time, and may represent signal quality output by the optical module.

In one embodiment, controlling the PHY chip to turn on the receive switch when the data path state indicates that the optical module enters the data path active state comprises: and judging whether the optical module enters a data path activation state according to the data path state, and modifying a receiving switch of the PHY chip from an off state to an on state when the data path state indicates that the optical module enters the data path activation state.

When the data path state represents that the optical module enters the data path activation state, the signal output by the optical module is indicated to be the best, so that data transmission between the switch and the optical module can be opened. Specifically, after the switch reads the data path state corresponding to the optical module, whether the optical module enters the data path activation state needs to be judged according to the data path state, if the data path state does not indicate that the signal quality output by the optical module is not the best, connection abnormality easily occurs, the receiving switch of the PHY chip cannot be turned on, otherwise, if the optical module is judged to have entered the data path activation state, the signal quality output by the optical module is indicated to have reached the optimum, that is, the signal quality output by the optical module has been guaranteed, therefore, the switch can modify the receiving switch of the PHY chip from the off state to the on state, that is, the switch turns on the receiving switch of the PHY chip, so that data transmission is performed between the optical module and the switch, and at the moment, the connection abnormality rate between the optical module and the switch is far reduced.

In one embodiment, determining whether the optical module enters a data path activation state based on the data path state includes: acquiring a first data path state corresponding to the optical module, judging whether the optical module is in a data path inactive state according to the first data path state, acquiring a second data path state corresponding to the optical module when the optical module is not in the data path inactive state, judging whether the optical module is in a data path initialization state according to the second data path state, acquiring a third data path state corresponding to the optical module when the optical module is not in the data path initialization state, and judging whether the optical module enters the data path active state according to the data path state.

When the optical module enters a module in-place state, the data path state of the optical module does not reach a data path activation state at a time, so that a first data path state corresponding to the optical module can be obtained, whether the optical module is in a data path non-activation state is judged according to the first data path state, if the first data path state indicates that the optical module is in the data path non-activation state, it is indicated that the optical module just performs signal processing, and the signal quality is not the best at the moment, so that the optical module waits for a period of working processing, and then a second data path state corresponding to the optical module is obtained.

Further, if the first data path state indicates that the optical module is not in the data path inactive state, which indicates that the optical module has been in operation for a period of time, the optical module has already entered the next stage, and at this time, a second data path state corresponding to the optical module at this time may also be obtained, and whether the optical module is in the data path initialization state is determined by the second data path state, and if the optical module is not in the data path initialization state, which indicates that the optical module may have entered the final stage, a third data path state is obtained, and whether the optical module enters the data path active state is determined by the third data path state.

When the optical module enters a module in-place state, the data path state of the optical module is usually a data path inactive state, a data path initialization state and a data path activation state, when the optical module just enters the module in-place state, the data path is just electrified, the data path state is the data path inactive state, when the data path of the optical module is ready, the data path state enters the data path initialization state from the data path inactive state, when the data path of the optical module is ready, the optical module is electrified normally, and when the data path of the optical module is ready, the data path state enters the data path activation state from the data path initialization state, and the signal quality output by the optical module is optimal, so that the signal quality output by the optical module can be ensured.

Specifically, when the read data path state indicates that the optical module does not enter the data path activation state, it indicates that the optical module is not completely ready at this time, and the output signal quality is not optimal, so that the preset waiting time is obtained, which may be set according to the actual service condition, the actual application scenario, or the actual product requirement, and is the waiting time for re-obtaining the data path state of the optical module, if the data path state is obtained immediately, the step of obtaining the data path state of the optical module is returned after the preset waiting time, that is, the data path state of the optical module is re-obtained until the obtained data path state indicates that the optical module enters the data path activation state.

Specifically, when the read data path state indicates that the optical module enters the data path activation state, it is indicated that the optical module is completely ready at this time, and the output signal quality is already optimal, that is, the quality of the signal output by the optical module can be ensured, and abnormal connection between the switch and the optical module is reduced. Therefore, a receiving switch of the PHY chip can be turned on to receive a receiving signal sent by the optical module, so that data transmission between the optical module and the switch is realized. Specifically, the switch sends an on command to the PHY chip, and after the PHY chip receives the on command, the PHY chip modifies a switch state corresponding to the receiving switch according to the on command, modifies the receiving switch from an off state to an on state, and successfully turns on the receiving switch of the PHY chip.

In one embodiment, modifying the receive switch of the PHY chip from an off state to an on state includes: the receiving switch of the PHY chip is modified from an off state to an on state by a complex programmable logic device.

The receiving switch of the PHY chip can be modified from an off state to an on state by the hardware complex programmable logic device CPLD.

In one embodiment, the control PHY chip turns on the receiving switch to enable data communication between the optical module and the switch, including: and receiving the signal sent by the optical module, and decoding the signal to obtain a signal processing result.

When the switch controls the PHY chip to turn on the receiving switch, data communication can be carried out between the optical module and the switch, the optical module can send signals to be processed to the switch, the switch receives the signals sent by the optical module, processes the signals to obtain signal processing results, and finally, the processed signal processing results are sent to the optical module. After the switch and the optical module perform data communication by the method, the probability of abnormal connection is reduced, so that the data transmission efficiency between the switch and the optical module can be improved, and the signal transmission between the switch and the optical module is ensured.

In one embodiment, obtaining the data path state of the optical module includes: and reading a register corresponding to the optical module through the complex programmable logic device, and acquiring the data path state from the register through the complex programmable logic device.

The Complex programmable logic device CPLD (Complex Programmable Logic Device) is a simple name of the Complex PLD, which is a logic element more Complex than the PLD, and is a digital integrated circuit that a user constructs a logic function according to the needs of the user. Specifically, the switch can read the register corresponding to the optical module through the complex programmable logic device, and then acquire the data path state from the register through the complex programmable logic device.

In one embodiment, the optical module is inserted into the switch, so as to implement interconnection between the server network card and the switch or interconnection between the switch and other switches.

The Optical Module (Optical Module) is an optoelectronic device for implementing photoelectric conversion and electro-Optical conversion functions, and can implement interconnection of a network card and a switch and interconnection of switches at different levels. Therefore, the current switch is all the optical signals sent by the passive receiving optical module, namely, the optical module is inserted into the switch, the switch can passively receive the optical signals sent by the optical module, if the signal quality output by the optical module is poor or the performance of the switch is poor, the connection between the optical module and the switch is easily affected, and the abnormal rate of the connection between the optical module and the switch is increased. The switch inserted with the optical module can also perform data communication with other switches inserted with the optical module.

In a specific switch application scenario, as shown in fig. 2, fig. 2 shows a schematic diagram of a switch data communication method in an embodiment, which specifically includes the following steps:

1) The optical module is normally inserted into the switch and connected with the optical fiber.

2) The switch detects that the optical module is in place.

3) The switch controls the optical module to enter an LP MODE (low power consumption state) in which the optical module cannot normally operate.

4) The switch detects whether the RX side (receiving switch) signal reception of the PHY is off, and if not, the switch controls the signal on the RX side (receiving switch) of the PHY chip to be off.

5) The light module releases LP MODE (releases the low power state) and powers up normally.

6) After the optical module is normally powered on, the switch accesses a register of an internal mark data path of the optical module through an I2C path of the optical module, judges whether the optical module enters a datapath activated state, and if the state is not carried out temporarily, re-accesses the register after a period of time is suspended, and judges.

7) If the optical module has entered into the datapath active state, the switch controls the signal reception on the RX side (receiving switch) of the PHY to be turned on, and the switch starts to normally receive the signal from the optical module, and starts the link procedure with the optical module.

8) And the optical module completes link on the switch.

It should be understood that, although the steps in the above-described flowcharts are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
