Description
Technical Field
The present invention relates to the field of initialization, and in particular, to a PHY initialization method, system, device, and storage medium.
Background
With the improvement of the requirements on the communication rate and the transmission distance, there are more and more scenes using optical fibers as transmission media in a computer network, and meanwhile, an optical module is also required to receive optical signals, and after optical/electrical signal conversion, electrical signals are sent to the PHY through an optical module interface. The optical module is usually independent from the optical module interface as a module, and the optical module is connected to the optical module interface and can be hot-plugged. When the optical module is inserted into the optical module interface, the PHY connected to the other end of the optical module interface and the optical signal connected to the optical module also need to operate in a correct state, and the link can be correctly connected.
In the prior art, the optical module can be pulled out from the optical module interface at any time, and the optical fiber can also be pulled out from the optical module at any time, which means that for the optical signal receiving end of the optical module, the optical signal is unstable, and the unstable optical signal can cause the electrical signal sent by the optical module to the optical module interface and the PHY signal to be unstable. An error may be generated after the unstable electrical signal is received by the PHY chip, so that the PHY chip considers that an error occurs on the communication link or the Serdes receiver inside the PHY chip is abnormal, and stays in an error state.
Therefore, before and after the optical fiber or the optical module is plugged, the optical module interface and the PHY chip do not take specific logic actions, and the Serdes transmitter and the receiver connected to the optical module interface and the optical module on the PHY chip are always in a working state, so that the abnormality of plugging and unplugging the optical module and the optical fiber to the local interface and the interface opposite-end interface cannot be avoided. The abnormality may cause errors on the PHY chip or the PHY may fail to communicate properly.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In the embodiment of the present invention, LOS refers to Lost of Signal, and a Signal or register in the optical module is used to indicate that the optical module does not receive an optical Signal at this time; PCS refers to Physical Coding Sublayer, here defined in IEEE 802.3; PMA refers to Physical Medium Attachment, here the Physical media Attachment sublayer defined in IEEE 802.3; PHY is a Physical layer defined in IEEE802.3, includes sublayers such as PCS and PMA, and is a Physical layer in a device in a communication link, and realizes a function of transmitting and receiving signals on a communication medium. DDM refers to Digital Diagnostic Monitoring, and Digital Diagnostic function is defined by SFF-8472.
According to an aspect of the present invention, an embodiment of the present invention provides a PHY initialization method, as shown in fig. 1, which may include the steps of:
s1, detecting the on-position state of the optical module;
s2, in response to the fact that the optical module is detected to be in the in-place state, controlling the PHY to turn on a signal transmitter corresponding to the optical module;
s3, judging whether the optical module is in a lost state;
s4, responding to the optical module not being in the loss state, controlling the PHY to open a signal receiver corresponding to the optical module, and detecting whether a PCS layer in the PHY generates a preset report;
and S5, responding to the condition that no preset report is generated, turning off the signal receiver and re-detecting whether the optical module is in a loss state.
The scheme provided by the invention defines a set of PHY initialization flow by identifying the in-situ signal and the LOSs signal (LOS signal) of the optical module, and is used for avoiding the situations of abnormal error codes and abnormal functions of the interface caused by the plugging and unplugging of the optical module on the interface of the optical module or the plugging and unplugging of the optical fiber on the optical module.
In some embodiments, as shown in FIG. 2, the optical module includes an LOS register and physical in-place signal pins. When the optical module is inserted into the optical module interface, the on-site signal on the optical module interface is driven to a low level by the optical module. After the device is started, the controller detects the presence signal on the optical module interface in a fixed period, and judges whether the optical module is accessed, and if the controller detects that the presence state of the optical module is changed from "not in place" (corresponding to the high level of the presence signal) to "in place" (corresponding to the low level of the signal), the controller needs to execute an initialization action. If the controller detects that the on-position signal is changed from on-position to off-position, the closing action is required to be executed. The act of detecting the presence signal is therefore always performed after the device has been started.
In some embodiments, further comprising:
responding to the fact that the optical module is in the loss state, detecting whether the optical module is in the loss state again every preset time period until the optical module is not in the loss state.
In some embodiments, further comprising:
and controlling the PHY to close a signal transmitter and a signal receiver corresponding to the optical module in response to detecting that the optical module is changed from an on-bit state to an off-bit state.
In some embodiments, detecting an in-place status of a light module further comprises:
detecting the level of an in-place pin of the optical module;
and confirming that the optical module is detected to be in the in-place state in response to the times of continuously detecting that the level of the in-place pin is the low level for a preset number of times.
In some embodiments, determining whether the light module is in a lost state further comprises:
detecting a first register of the optical module;
and judging whether the optical module is in a lost state or not according to the value of the first register.
In some embodiments, determining whether the light module is in a lost state further comprises:
acquiring DDM information in the optical module;
and judging whether the optical module is in a loss state or not based on the optical power in the DDM information.
In some embodiments, detecting whether a preset report is generated by a PCS layer in the PHY further comprises:
detecting whether the PCS layer generates a connection establishment report.
Specifically, as shown in fig. 3, when it is detected that the optical module is changed from the non-live state to the live state, the optical module that needs to perform the reset operation according to the protocol standard is reset. And then the controller turns on a signal transmitter corresponding to the PHY chip and the optical module and transmits a signal to the optical module. The controller judges whether the optical module is in an LOS state at the moment, if not, the controller enters the next step, the electric signal receiver of the PHY chip is turned on to prepare to receive the electric signal converted from the optical signal from the optical module, if the optical module is still in the LOS state, the controller waits for time t2 to detect whether the optical module is in the LOS state again, and the steps are repeated until the LOS state is released. If the LOS state is released, after waiting t1, it is detected whether the physical layer chip reports that the link connection is established (i.e., link up), and if the link connection is reported to be established, the controller may consider the port link up at this time to notify the program using the optical module interface that the optical module interface can normally communicate. If the PCS in the PHY does not report linkup or does not report HI-BER or Fault state defined in IEEE802.3, the electric signal receiver of the optical module corresponding to the PHY chip is closed, and the LOS state is detected again.
The LOS state can access the LOS register of the optical module through the LOS pin or the I2C bus of the optical module, and for the optical module supporting DDM information acquisition, the received optical power in DDM information in the optical module can be preferably accessed through the I2C bus to perform judgment, the judgment standard can be a predefined value, or an LOS optical power early warning value recorded in the DDM information of the optical module, and when the received optical power in the DDM information is smaller than a preset value or an early warning value, the LOS state is judged. These registers for DDM information are defined by the optical module standard.
And after the optical module is detected to be changed from the in-position to the out-of-position, the receiver and the transmitter corresponding to the PHY and the optical module are turned off.
For the detection of the on-bit signal, the controller may repeatedly detect the on-bit signal, each time the detection interval is t3, and if the on-bit signal is detected to be in the "on-bit" (low) state 3 times or other times defined, the on-bit signal is considered to be in the on-bit state, otherwise, the on-bit state is not detected.
The scheme provided by the invention defines a set of PHY initialization flow by identifying the in-situ signal and the LOSs signal (LOS signal) of the optical module, and is used for avoiding the situations of abnormal error codes and abnormal functions of the interface caused by the plugging and unplugging of the optical module on the interface of the optical module or the plugging and unplugging of the optical fiber on the optical module.
