Detailed Description
Illustrative embodiments of the present application include, but are not limited to, an optical communication method, system, storage medium, and apparatus.
The technical solutions of the present application will be described below with reference to fig. 1 to 5.
In some embodiments, the optical communication device may be an optical line terminal (optical line terminal, OLT) device, an optical network unit (optical network unit, ONU) device, etc. in a passive optical network (passive optical networks, PON) communication system; in other embodiments, the optical communication device may also be a router, a switch, a server, an optical transport network (optical transport network, OTN) transport device, or the like, without limitation.
In some embodiments, as shown in fig. 1, the optical communication device 100 includes a communication board and an optical communication module, where one end of the optical communication module is connected to the communication board through an upper port, and the other end of the optical communication module is connected to an optical cable for receiving or transmitting an optical signal. It will be appreciated that a communications board may be configured with one or more optical communications modules.
In some embodiments, the communications board may be a printed circuit board assembly (printed circuit board assembly, PCBA) that may include an optical digital signal processor (optical digital signal processor, oDSP), drivers (DRV), transimpedance amplifiers (transimpedance amplifier, TIA), microcontrollers (microcontroller unit, MCU), etc. for electrical signal processing.
In some embodiments, the optical communication module includes an optical receiving component for receiving an optical signal from the optical cable and converting the optical signal into an electrical signal, and an optical transmitting component for receiving the electrical signal from the communication board and converting the electrical signal into an optical signal, where the optical receiving component and the optical transmitting component may be packaged on the communication board in a chip package. In other embodiments, the optical communication module may be used not only to implement the function of photoelectric conversion, but also to implement a communication protocol related to optical communication, for example, PON related protocols such as PLOAM protocol, OMCI protocol, etc., which are not limited in particular.
The photoelectric conversion process of the optical communication device is exemplified below by an example in which the optical communication device is an OLT.
In some embodiments, the optical communication device is configured to send a downstream traffic optical signal to the ONU. Specifically, the optical communication device generates a downlink service electrical signal through the communication single board, and sends the downlink service electrical signal to the optical communication module through the communication single board; and then, the optical communication equipment performs photoelectric conversion on the downlink service electrical signal through the optical communication module to acquire a downlink service optical signal, and sends the downlink service optical signal to the ONU through the optical communication module based on an optical cable connected with the optical communication module.
In other embodiments, the optical communication device is configured to receive upstream traffic optical signals from the ONU. Specifically, the optical communication device receives an uplink service optical signal sent by the ONU through an optical cable connected with the optical communication module based on the optical communication module, and performs photoelectric conversion on the uplink service optical signal through the optical communication module to obtain an uplink service electrical signal; and then, the optical communication equipment sends the uplink service electric signal to the communication single board through the optical communication module, and processes the uplink service electric signal through the communication single board.
It may be understood that the optical communication device may also be an ONU, where an uplink service optical signal is sent to the OLT through the optical communication device, or a downlink service optical signal sent from the ONU is received through the optical communication device, and a specific photoelectric conversion process may refer to an example where the optical communication device is the OLT, which is not described herein.
In some embodiments, since the protocol for automatically negotiating the transmission rate is not configured between the optical communication module and the communication board, in order to ensure the transmission efficiency of the optical communication module and the communication board, such as the transmission efficiency of the electrical signal between the optical communication module and the communication board, the optical communication module is generally designed to have a fixed transmission rate based on the adapted transmission rate of the connected single communication board. However, the adaptive transmission rates of different communication boards may be different, and the optical communication module with a fixed transmission rate cannot be configured on other communication boards with different adaptive transmission rates.
Therefore, the application proposes an optical communication method, wherein a plurality of initial transmission rates are configured in an optical communication module, and when the optical communication module establishes communication connection with a certain communication single board, the optical communication module sequentially selects the initial transmission rate of a corresponding ordering bit from the plurality of initial transmission rates according to the sequence from high speed to low speed to establish communication connection with the communication single board. When the optical communication module determines that any initial transmission rate and the communication single board establish communication connection to meet the preset connection condition, the optical communication module takes the initial transmission rate as a target transmission rate so as to establish communication connection with the corresponding communication single board through the target transmission rate. In this way, the optical communication module can correspondingly adjust the transmission rate of the optical communication module based on the adaptive transmission rate of the connected communication single board through a plurality of initial transmission rates configured by the optical communication module. It can be understood that the optical communication module performs transmission rate adjustment through a plurality of initial transmission rates configured by the optical communication module, so that not only can the transmission efficiency between the optical communication module and the communication board be ensured, but also the transmission rate of the optical communication module can be correspondingly adjusted based on the adaptive transmission rate of the connected communication board, i.e. the optical communication module can be configured on a plurality of communication boards with different adaptive transmission rates, thereby improving the configuration performance of the optical communication module.
In some embodiments, when the optical communication module establishes a communication connection with the communication board through a certain initial transmission rate, if the initial transmission rate is a transmission rate within an adaptive transmission rate range corresponding to the communication board, it may be determined that the optical communication module establishes a communication connection with the communication board to meet a preset connection condition. For example, the adaptive transmission rate range corresponding to the communication board is 8 to 12 gigabits per second (Gbps), and when the optical communication module establishes communication connection with the communication board through the initial transmission rate of 5 gigabits per second, it can be determined that the communication connection established between the optical communication module and the communication board does not meet the preset connection condition; when the optical communication module establishes communication connection with the communication single board through the initial transmission rate of 10 gigabits per second, it can be determined that the communication connection established between the optical communication module and the communication single board meets the preset connection condition.
In other embodiments, whether the communication connection between the optical communication module and the communication board meets the preset connection condition may also be determined by the information such as the packet loss rate and the throughput when the data is transmitted between the optical communication module and the communication board, which is not particularly limited. For example, when the packet loss rate is smaller than a preset packet loss rate threshold, or the throughput is larger than a preset throughput threshold, it may be determined that the optical communication module establishes communication connection with the communication board to meet a preset connection condition.
In connection with the block diagram of fig. 1, fig. 2 illustrates a flow chart of steps of an optical communication method, according to some embodiments of the present application. As shown in fig. 2, the steps include:
s201: the optical communication module establishes communication connection with the communication single board.
In some embodiments, as shown in fig. 1, when the optical communication module is connected to the communication board through the uplink port and the optical communication module is powered on, the optical communication module establishes a communication connection with the communication board. It can be understood that the optical communication module may be configured to receive an electrical signal sent by the communications board and convert the electrical signal into an optical signal and then transmit the optical signal to other optical communications devices, and the optical communication module may be further configured to receive an optical signal sent by other optical communications devices and convert the optical signal into an electrical signal and then transmit the electrical signal to the communications board.
S202: the optical communication module acquires a plurality of initial transmission rates corresponding to the optical communication module and a plurality of sequencing bits corresponding to the initial transmission rates.
In some embodiments, when the optical communication module first establishes a communication connection with a communication board, for example, when the optical communication module is correspondingly configured on a certain communication board for the first time, or when the optical communication module is first powered on or powered on again, for example, the optical communication module obtains a plurality of initial transmission rates corresponding to the optical communication module and a plurality of ordering bits (corresponding to an instance of the first ordering bit) corresponding to the plurality of initial transmission rates.
It will be appreciated that the plurality of initial transmission rates may be ordered in descending order from high speed to low speed, or in ascending order from low speed to high speed. For example, the optical communication module is correspondingly configured with: three initial transmission rates of 10 gigabits per second, 5 gigabits per second and 1 gigabit per second are ordered in descending order of the plurality of initial transmission rates from high speed to low speed, and the order bit corresponding to the initial transmission rate of 10 gigabits per second is the highest order bit of the plurality of initial transmission rates, and the order bit corresponding to the initial transmission rate of 1 gigabit per second is the lowest order bit of the plurality of initial transmission rates.
S203: the optical communication module determines a target transmission rate from a plurality of initial transmission rates based on the plurality of sequencing bits, and establishes communication connection with the communication board based on the target transmission rate.
In some embodiments, after the optical communication module acquires a plurality of initial transmission rates, the optical communication module sequentially selects a corresponding initial transmission rate from the acquired plurality of initial transmission rates according to the order from high speed to low speed, and establishes a communication connection with the communication board. When the optical communication module determines that any initial transmission rate and the communication single board establish communication connection to meet the preset connection condition, the optical communication module takes the initial transmission rate as a target transmission rate so as to establish communication connection with the corresponding communication single board through the target transmission rate.
For example, when the optical communication module and the communication board establish communication connection for the first time, if the ordering bits corresponding to the plurality of initial transmission rates are ordered in descending order according to the transmission rates of the initial transmission rates, the optical communication module selects the initial transmission rate of the highest ordering bit from the plurality of ordering bits to establish communication connection with the communication board first time, so that the optical communication module can establish communication connection with the communication board through the initial transmission rate of the highest transmission rate.
Or for example, when the optical communication module and the communication single board establish communication connection for the first time, if the sorting bits corresponding to the plurality of initial transmission rates are sorted according to the ascending order of the transmission rates of the initial transmission rates, the optical communication module selects the initial transmission rate of the lowest sorting bit from the plurality of sorting bits to establish communication connection with the communication single board first time, so that the optical communication module can establish communication connection with the communication single board through the initial transmission rate of the highest transmission rate.
It can be understood that when the optical communication module and the communication board establish communication connection for the first time, the optical communication module first establishes communication connection with the communication board through the highest transmission rate configured by the optical communication module, and the communication efficiency between the optical communication module and the communication board can be improved through the higher transmission rate.
In other embodiments, when the communication connection between the optical communication module and the communication board through the initial transmission rate of the highest transmission rate does not meet the preset connection condition, if the initial transmission rate of the highest transmission rate does not meet the adaptive transmission rate range corresponding to the communication board, the optical communication module may sequentially select the corresponding initial transmission rate to establish the communication connection with the communication board according to the descending order or ascending order of the ordering bits. That is, when the optical communication module establishes a communication connection with the communication board through the initial transmission rate of the highest transmission rate and does not meet the preset connection condition, the optical communication module sequentially selects corresponding initial transmission rates from the plurality of initial transmission rates in order from high speed to low speed to establish a communication connection with the communication board. When the optical communication module establishes communication connection with the communication single board through any initial transmission rate and meets preset connection conditions, the initial transmission rate is used as a target transmission rate, so that communication connection is established with the corresponding communication single board through the target transmission rate.
It can be understood that the optical communication module performs transmission rate adjustment through a plurality of initial transmission rates configured by the optical communication module, so that not only can the transmission efficiency between the optical communication module and the communication board be ensured, but also the transmission rate of the optical communication module can be correspondingly adjusted based on the adaptive transmission rate of the connected communication board, i.e. the optical communication module can be configured on a plurality of communication boards with different adaptive transmission rates, thereby improving the configuration performance of the optical communication module.
In some embodiments, when the optical communication module and the communication board do not establish a communication connection for the first time, for example, when the optical communication module is configured on a certain communication board for the first time, the optical communication module may establish a communication connection with the communication board by using a transmission rate of the previous communication connection established with the communication board as a target transmission rate, so as to improve efficiency of establishing the communication connection between the optical communication module and the communication board.
In other embodiments, when the optical communication module and the communication board establish communication connection for the non-first time, for example, when the optical communication module is configured on a certain communication board for the non-first time, the optical communication module may also select corresponding initial transmission rates from the plurality of initial transmission rates in order from high speed to low speed to establish communication connection with the communication board in order to redetermine the target transmission rate when the optical communication module is powered on again, and redetermining the target transmission rate may improve the configuration accuracy of the optical communication module.
Fig. 3 illustrates a flow chart of steps of another optical communication method, according to some embodiments of the present application. It can be understood that the main execution body of each step in the flow shown in fig. 3 is an optical communication module. In order to simplify the description, the execution subject of each step will not be repeated in the description of each step of the flow shown in fig. 3. As shown in fig. 3, the steps include:
s301: the optical communication module is powered on.
In some embodiments, after the optical communication module is connected to a certain communication board through the upper connection port, the optical communication module is powered on to establish a communication connection with the communication board.
S302: a plurality of initial transmission rates are read from the configuration and a communication connection is established with the initial transmission rate at the maximum rate.
In some embodiments, after the optical communication module is powered on, the optical communication module reads a plurality of initial transmission rates corresponding to the optical communication module from the configuration, and establishes communication connection with the communication board through an initial transmission rate of a highest transmission rate among the plurality of initial transmission rates.
S303: whether the upper connecting port is up.
In some embodiments, when the optical communication module establishes a communication connection with the communication board through the initial transmission rate of the highest transmission rate to meet the preset connection condition, the step S304 is skipped to the uplink port up.
S304: and (5) ending. The optical communication module takes the initial transmission rate of the highest transmission rate as a target transmission rate to establish communication connection with the communication single board through the target transmission rate.
In other embodiments, when the optical communication module establishes a communication connection with the communication board through the initial transmission rate of the highest transmission rate and does not meet the preset connection condition, the uplink port is not up, and the step S305 is skipped.
S305: the communication connection is established sequentially through the configured plurality of initial transmission rates in order of high speed to low speed.
In some embodiments, the optical communication module sequentially selects a corresponding initial transmission rate from the plurality of initial transmission rates in order from high speed to low speed, and establishes a communication connection with the communication board.
S306: whether the upper connecting port is up.
In some embodiments, when the optical communication module establishes a communication connection with the communication board through the corresponding initial transmission rate and does not meet the preset connection condition, the step goes to step S305 to select a lower initial transmission rate to establish a communication connection with the communication board than the initial transmission rate selected last time.
In some embodiments, when the optical communication module establishes a communication connection with the communication board through any initial transmission rate to meet the preset connection condition, the step S307 is skipped.
S307: the current rate is saved.
In some embodiments, the optical communication module uses the initial transmission rate meeting the preset connection condition as a target transmission rate, so as to establish communication connection with the corresponding communication board through the target transmission rate, and stores the initial transmission rate so as to establish communication connection with the communication board again when the communication connection is subsequently established with the communication board again, and can directly establish communication connection with the communication board through the stored target transmission rate.
S308: and (5) ending.
It can be understood that the optical communication module performs transmission rate adjustment through a plurality of initial transmission rates configured by the optical communication module, so that not only can the transmission efficiency between the optical communication module and the communication board be ensured, but also the transmission rate of the optical communication module can be correspondingly adjusted based on the adaptive transmission rate of the connected communication board, i.e. the optical communication module can be configured on a plurality of communication boards with different adaptive transmission rates, thereby improving the configuration performance of the optical communication module.
