Detailed Description
The present invention 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 invention 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 invention.
In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other. The invention will be described in detail below with reference to the drawings and examples.
Example 1:
as shown in fig. 2, embodiment 1 of the present invention provides a method for monitoring alarm and status signals of a remote optical module, which is described from a local optical module side, and includes the following steps:
step 101: the MCU (Microcontroller Unit, micro control unit) of the local side optical module monitors hardware alarm and status signals and sets a hardware flag for switching the hardware pin signal working mode of the optical module. The step sets a Local or remote hardware mark in the optical module, wherein the Local mark can be realized by a register or bit in software, or can be realized by the hardware level of a hardware circuit. In addition, the hardware alarm and status signals, i.e., subsequent hardware signals, are represented using one or more of a plurality of bits, a byte, and a plurality of bytes.
Step 102: when the hardware mark value is A, the working mode of the hardware pin signal of the optical module is switched to the local side mode, and the local side equipment detects the hardware signal of the optical module. The local side mode in the step specifically comprises the following steps: the local side optical module closes the hardware monitoring signal transmission unit and communicates the hardware signal of the local side optical module to the optical module electrical pin so as to upload the hardware signal of the local side optical module to the local side equipment main processor. In general, for example, when a of the hardware flag value is 1, that is, when the hardware flag local=1, the pin hardware signal indicating the optical module is Local itself.
Step 103: when the hardware mark value is B, the working mode of the hardware pin signal of the optical module is switched to a far-end mode, and the local side equipment detects the hardware signal mirrored by the far-end optical module. The remote mode in this step specifically includes: the local side optical module starts a hardware monitoring signal transmission unit, analyzes a remote mirror image data packet sent from the remote side optical module and stores the remote mirror image data packet; the local side optical module disconnects the logic connection between the hardware signal of the local side optical module and the electric pin of the optical module; the local side optical module communicates the hardware signal of the far-end mirror image to an optical module electric pin so as to upload the hardware signal of the far-end mirror image to a local side equipment main processor. In general, for example, when B of the hardware flag value is 0, that is, when the hardware flag local=0, the pin signal indicating the optical module is mirrored from the far end. When the optical module is initialized to be powered on, the Local value can be 1 or 0 by default.
Through the steps, the Local equipment host can obtain the hardware state or the alarm signal of the Local or the remote optical module by reading or rewriting the Local mark. The Local device host can also record and store the Local mark and the hardware signal information together, so that subsequent inquiry or information source distinguishing can be facilitated.
For this embodiment, the workflow of the local side optical module for receiving the mirror image data is shown in fig. 3, and specifically includes the following procedure.
Step 10: and the MCU of the local side optical module is powered on and started.
Step 11: the local side optical module MCU monitors hardware signal state or alarm.
Step 12: and judging whether the hardware flag Local is equal to 1, if so, proceeding to step 13, and if not, proceeding to step 15.
Step 13: and closing the hardware monitoring signal transmission unit of the local side.
Step 14: the hardware signal of the local side is communicated to an optical module electric interface (namely an electric pin of the optical module), and the hardware signal of the local side is uploaded to a main processor of the local side equipment. After the step is completed, the step 11 is returned, and the local side optical module MCU continues to monitor the hardware signal state or alarm.
Step 15: and starting a hardware monitoring signal transmission unit of the local side.
Step 16: analyzing the far-end mirror image data packet separated from the detector, and recovering the original far-end hardware signal level state after judgment, and storing.
Step 17: the local MCU disconnects the hardware signal of the MCU from the logic connection of the electric pin of the optical module.
Step 18: the local side MCU communicates the hardware signal state of the far-end mirror image to the optical module electric pin, and uploads the hardware signal of the far-end mirror image to the local side equipment main processor.
Optionally, the Local side device host processor may modify the Local flag through an optical module management interface (e.g. I2C) according to needs, so that local=1 or local=0 is alternately made, so as to achieve both the hardware and the mirror data of the Local side device host processor.
In summary, in the embodiment of the present invention, only one hardware flag for switching the local mode or the remote mode needs to be newly added to the software of the local device, so that the acquisition and the configuration of the hardware signal of the remote optical module can be realized, the influence on the existing device is small, and the deployment is easy.
Example 2:
as shown in fig. 4, embodiment 1 of the present invention provides a method for monitoring alarm and status signals of a remote optical module, wherein the method is described from a side of the remote optical module, and comprises the following steps:
step 201: the MCU of the remote optical module monitors hardware alarms and status signals and sets a hardware flag for switching the working mode of the optical module. The step sets a Local or remote hardware mark in the optical module, wherein the Local mark can be realized by a register or bit in software, or can be realized by the hardware level of a hardware circuit.
Step 202: when the hardware marking value is A, the working mode of the optical module is switched to a local side mode, and the remote equipment closes the hardware monitoring signal transmission unit. In general, for example, when a of the hardware flag value is 1, that is, when the hardware flag local=1, the pin hardware signal of the Local optical module indicates that the Local optical module is the Local itself, and the Local optical module does not need the remote device to mirror the past hardware signal, so the remote device turns off the hardware monitoring signal transmission unit and does not perform the mirror transmission of the hardware signal.
Step 203: when the hardware marking value is B, the working mode of the optical module is switched to a far-end mode, and the far-end equipment starts the hardware monitoring signal transmission unit and sends a far-end mirror image data packet to the local side optical module. The remote mode in this step specifically includes: the remote optical module starts a hardware monitoring signal transmission unit; the hardware monitoring signal transmission unit packages the hardware signal of the far-end optical module into a far-end mirror image data packet; and superposing the far-end mirror image data packet on a laser and sending the far-end mirror image data packet to a local optical module. In general, for example, when B of the hardware flag value is 0, that is, when the hardware flag local=0, the pin signal of the Local optical module is mirrored from the far end, and the Local optical module needs the far end device to mirror the past hardware signal, so the far end device starts the hardware monitoring signal transmission unit to perform the mirror transmission of the hardware signal.
Through the steps, the remote equipment host can determine whether to transmit the hardware state or the alarm signal mirror image of the remote equipment host to the Local optical module by reading the Local mark. The remote equipment host can also record and store the Local mark and the hardware signal information together, so that the subsequent inquiry or the distinguishing of the information sources is facilitated.
For the present embodiment, the workflow of transmitting mirror data by the remote optical module is shown in fig. 5, and specifically includes the following procedure.
Step 20: the MCU of the far-end light module (also referred to as an antenna-side light module, the antenna side in this embodiment is the far end) is powered on.
Step 21: the remote light module MCU monitors hardware signal status or alarms, and the step can synchronize information to the remote equipment main processor.
Step 22: it is determined whether the hardware flag Local is equal to 1, if yes, step 23 is entered, and if no, step 24 is entered. The hardware mark in the step carries out data transmission through the data channel at the bottom layer so as to ensure the consistency of the hardware marks at the local end and the far end.
Step 23: the remote hardware monitoring signal transmitting unit is closed. After this step, the process returns to step 21, and the remote light module MCU continues to monitor the hardware signal status or alarm.
Step 24: the remote hardware monitoring signal transmitting unit is started.
Step 25: and the remote hardware monitoring information transmission unit performs data encapsulation and transmits a data packet to the local side optical module according to a certain transmission rule.
Step 26: and superposing the monitoring information data on the laser and sending the monitoring information data to the local side optical module.
In summary, the hardware tag in the embodiment of the present invention performs data transmission through the data channel at the bottom layer, and the host processor at the far end does not need to participate in the transmission of the hardware signal, so that links through which the state and the alarm signal are transmitted can be reduced, thereby reducing processing delay, enhancing instantaneity, and increasing rapid fault processing and recovery capability of the network.
Example 3:
based on the methods provided in embodiment 1 and embodiment 2, this embodiment 3 further describes the interaction procedure of the present invention by a specific implementation example.
Firstly, for the existing optical module, different packaging forms and electrical interface definitions are adopted, but a plurality of hardware signals are specified on the electrical interface to inform the working state of the optical module to a main processor CPU of the device, the hardware signals are required to respond quickly and have higher real-time performance, the response of the main processor is triggered through the hardware signals, and the main processing is prompted to further analyze specific alarm sources and state information values inside the optical module through a management interface (such as I2C) of the optical module. For example, in an optical module of sfp+ (Small Form-factor Pluggables), the definition of the electrical interface is shown in fig. 6. The two most critical pin status alarm signals tx_fault indicate that the laser has serious faults, and rx_los indicates that the receiving end has no optical signal. The other status signals RS0, RS1 represent the operating rate status. Tx_disable is used to turn the laser on/off and Mod_ABS indicates that the optical module has been inserted into the device. Both these status and alarm signals can be mirrored onto the local optical module as desired using the methods of embodiments 1, 2 of the present invention.
Compared with the conventional optical module, embodiment 3 of the present invention provides an optical module with a remote hardware signal mirroring function, as shown in fig. 7, in which a Local/remote mirroring flag Local (i.e. hardware flag), a hardware monitoring information transmitting unit, and a related flow of transmitting data packets are mainly configured in the conventional optical module. According to the embodiment, the remote or local mirror image mark is adopted, data transmission is carried out through the data channel of the bottom layer, a main processor of the remote does not need to participate, and the state of a hardware signal of an electrical interface of the remote optical module is mirrored on an electrical interface hardware signal of the local optical module, so that the local equipment can easily acquire the working condition of the remote optical module.
Based on the optical module with the far-end hardware signal mirroring function shown in fig. 7, in the optical module of this embodiment, the Local side/far-end mirror mark Local is used to switch the working mode of the hardware pin signal of the optical module, when local=1, it indicates that the hardware pin hardware signal of the current optical module is the Local side itself, and the Local side device detects the hardware signal of the optical module itself. When local=0, it indicates that the hardware pin signal of the current optical module is mirrored from the far-end, and the Local side device detects the hardware signal mirrored from the far-end antenna side optical module. Local/remote mirror flag Local may be controlled by a register or bit, or by hardware level (e.g., high level is Local and low level is remote mirror).
The MCU in the optical module is responsible for monitoring all hardware state signals, and can convert the monitored signal states into data frames or data packets according to a certain rule (for example, periodically or based on each condition triggering type), and the data frames or data packets are overlapped on the laser through an optional external matching circuit and sent out. Meanwhile, the monitoring information data packet separated from the detector is processed by the matching circuit and is sent to the hardware monitoring information transmission unit for analysis and conversion into the original hardware signal level.
After the local side and the far-end antenna side adopt the optical module with the hardware mirror function, the transmission paths of the hardware signal alarms or state information of the far-end antenna side optical module are shown by the dotted arrow in fig. 8, the states of the hardware signal alarms and the like of the far-end antenna side optical module do not need participation of the main processor of the antenna side, and the states can be reported to the main processor of the local side only through the MCU in the optical module, so that the modification of software and hardware of the far-end antenna side equipment is greatly reduced, the maintainability threshold of the far-end antenna side equipment is reduced, the equipment stability is improved, and the rapid deployment and application of the functions are easy. Meanwhile, because the alarm transmission path is obviously shortened, the real-time performance of the 5G forwarding network on fault monitoring and recovery is improved.
In the hardware monitoring information transmitting unit of the preferred embodiment, the hardware signals may be encapsulated into data packets in a certain manner. For example, a hardware signal may be represented by a few bits or a byte, which are then added to the header and trailer identifiers to form a completed packet for transmission.
Mode one: each hardware pin signal is represented by several bits. For example, each hardware signal is represented by 4 bits, so that 8 bits of the two signals can form a byte, and a plurality of bytes can form a data packet for uninterrupted transmission. As shown in fig. 9, a complete packet is shown. In this manner, the state of representing a hardware signal by a plurality of bits may have a certain error correction capability, and if tx_fault is represented by 6 bits, a decision rule may be preset: if there are more than 4 bits with the same value, the 4 bit value is used to determine the state of Tx_Fault. For example, when the optical module is operating, tx_fault=1 indicates that the laser is malfunctioning, and tx_fault=0 indicates that the laser is operating properly. Assuming that tx_fault=1 is denoted by 111111, when an error occurs during transmission, the receiving end becomes 101110 because 4 bits are received to be equal to 1, and the received tx_fault=1 is finally determined according to a decision rule. Thus, the receiving end can tolerate 2 bit errors without misjudgment.
Mode two: each hardware pin signal is represented by 1 or more bytes. The use of multiple bytes to represent a hardware signal may have a stronger error correction capability, and the decision concept and manner during reception are similar and will not be described again.
In order to improve the instantaneity of the hardware signal mirror image, corresponding data packets can be formed periodically and sent uninterruptedly, or the MCU can be triggered to form the data packets to be sent out in time by finding that a certain hardware signal changes. The length and the sending frequency of the data packet can be set in software, so that the requirement of network fault monitoring instantaneity is met. In addition, in order to adapt to different application scenes, part of hardware signals of the optical module electrical interface can be selectively mirrored, and the rest of hardware signals are not mirrored.
It should be noted that, in the above example of the embodiment, the remote antenna side optical module only transmits the image data, and does not receive the image data. The local side optical module does not send mirror image data and only receives the mirror image data. As shown in fig. 10, this is a transmission method of a master/slave mode, in which a local optical module is used as a master device, a remote antenna side optical module is used as a slave device, and only a path for transmitting mirror image data of the slave device to the master device is provided. In another implementation manner of this embodiment, in order to adapt to other usage scenarios, both the local optical module and the remote antenna side optical module may transmit the mirror image data and receive the mirror image data at the same time, so as to form a bidirectional peer-to-peer transmission manner. As shown in fig. 11, in the peer-to-peer transmission method, the software of the local optical module and the remote antenna side optical module needs to have the processing functions of the processes in embodiments 1 and 2 at the same time, that is, the hardware monitoring information transmission unit of the local optical module may send the image data to the hardware monitoring information transmission unit of the remote antenna side optical module, and may also receive the image data sent by the hardware monitoring information transmission unit of the remote antenna side optical module; likewise, the hardware monitoring information transmitting unit of the remote antenna side light module can not only transmit the mirror image data to the hardware monitoring information transmitting unit of the local side light module, but also receive the mirror image data transmitted by the hardware monitoring information transmitting unit of the local side light module.
In summary, in the embodiment of the present invention, only one hardware flag for switching the local mode or the remote mode needs to be newly added to the software of the local device, so that the acquisition and the configuration of the hardware signal of the remote optical module can be realized, the influence on the existing device is small, and the deployment is easy. In addition, the hardware mark carries out data transmission through the data channel of the bottom layer, a main processor at the far end does not need to participate, and links through which state and alarm signals are transmitted can be reduced, so that processing delay is reduced, instantaneity is enhanced, and quick fault processing and recovery capacity of a network are improved.
