Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

In an exemplary embodiment, fig. 1 is a schematic structural diagram of a switching device provided in the present application, and referring to fig. 1, the switching device includes: the optical backplane 11 is respectively connected with the first single board 12 and the second single board 13, and the number of the second single boards 13 is at least two;

the optical backplane 11 is configured to establish a connection between the first board 12 and the second board 13, where the number of light source devices corresponding to optical signals accessed to the second board 13 is smaller than the number of connection signals between the first board 12 and the second board 13.

The optical backplane 11 may be understood as a backplane that establishes optical connection between the first veneer 12 and the second veneer 13. For example, the connection between the first board 12 and the second board 13 is established through an optical fiber on the optical backplane 11. The specific content of the first board 12 and the second board 13 is not limited here, and may be optical communication boards. For example, the first board 12 is a service board or a switch board, and correspondingly, the second board 13 is a switch board or a service board.

The optical signal output by the first board 12 may be connected to the second board 13 on the optical backplane 11, for example, the second board 13 is connected to the optical backplane 11 through an optical fiber. When the first veneer 12 and the second veneer 13 are connected, the number of the light source devices corresponding to the optical signal accessed to each second veneer 13 is smaller than the number of the connection signals between the first veneer 12 and each second veneer 13, so that the technical problem that the light source devices cannot be independently turned off when the optical signal output by each light source device in the first veneer 12 is respectively connected to each second veneer 13 is solved, the probability that each light source device of the first veneer 12 is independently controlled is improved, and the power consumption of the switching device can be effectively reduced.

The light source device may be a device that generates a light source, and is not limited herein, such as a laser. The number of connection signals may be understood as the number of signals connected between the first board 12 and each second board 13. For example, the first board 12 needs to have 4 pairs of optical fibers connected to each second board 13, i.e. the number of connection signals is 4.

When the first board 12 and the second board 13 are connected, it is only required to ensure that the number of the light source devices corresponding to the optical signal accessed to each second board 13 is less than the number of the connection signals between the first board 12 and the second board 13, and a specific connection manner is not limited herein.

In an example, the present application may sequence optical signals corresponding to each optical source device in the first single board 12, where the optical signals corresponding to one optical source device are adjacent in a queue, and then sequentially access the sequenced optical signals to each second single board 13, so as to ensure that the number of the optical source devices corresponding to one second single board 13 is less than the number of the connection signals.

In an example, the present application may determine the connection manner between the first board 12 and the second board 13 based on the number of connection signals and the number of paths of the optical signal output by one optical source device in the first board 12. Specifically, when the number of paths is greater than the number of connection signals and is not a multiple of the number of connection signals, or when the number of connection signals is greater than the number of paths and is not a multiple of the number of paths, the remaining optical signals that are not accessed to the second board 13 by each light source device in the first board 12 may be sequenced and then accessed to the remaining unconnected second board 13. When the remaining optical signals that are not connected to the second board 13 are sorted, the optical signals corresponding to the same optical source device are adjacent to each other, and the number of the optical signals that are connected to the second board 13 after sorting is determined based on the number of the connection signals required by the remaining unconnected second board 13.

The optical signal of each light source device in the first single board 12 that is not accessed to the second single board 13 may be understood as the optical signal of the light source device that is left after being accessed to the corresponding second single board 13. Illustratively, the first board 12 includes four light source devices, the number of paths of the optical signal corresponding to each light source device is 3, the number of the second boards 13 is 3, and the number of the connection signals is 4. One of two optical source devices of the first single board 12 may be all connected to the second single board 13, and one optical signal of the other optical source device may be connected to the second single board 13; one of the two remaining optical devices in the first board 12 may be all connected to the second board 13, and an optical signal in the other optical device may be connected to the other second board 13; the remaining unaccessed optical signals in each optical source device in the first single board 12 are accessed to the remaining second single board 13.

The application provides a switching device, the switching device establishes connection between a first veneer and a second veneer through an optical back plate, the number of light source devices corresponding to optical signals accessed to the second veneer is smaller than the number of connection signals between the first veneer and the second veneer, so as to reduce the number of the light source devices connected to the second veneer, increase the probability that the light source devices are independently adjusted, and further reduce the power consumption of the switching device.

On the basis of the above-described embodiment, a modified embodiment of the above-described embodiment is proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the above-described embodiment are described in the modified embodiment.

In an embodiment, the connection mode between the first board and each of the second boards is determined based on the number of connection signals between the first board and each of the second boards and the number of paths of optical signals output by one optical source device on the first board.

The connection mode between the first single board and the second single board may be determined by comparing the number of paths and the number of connection signals, so as to ensure that the number of light source devices corresponding to the optical signal accessed to each second single board is smaller than the number of connection signals between the first single board and each second single board. Here, the specific connection manner is not limited, as long as the number of the light source devices corresponding to the optical signal accessed to each second board is ensured to be smaller than the number of the connection signals.

For example, when the number of paths is equal to the number of connection signals, all optical signals corresponding to one light source device may be accessed to one second board, or optical signals corresponding to at least two light source devices may be accessed to one second board, and the number of accessed optical signals and the number of light source devices may be determined according to the number of connection signals; when the number of paths is less than the number of connection signals and the number of connection signals is a multiple of the number of paths, light corresponding to a first set number of light source devices may be accessed to a second board, and the first set number may be greater than or equal to the quotient of the number of connection signals divided by the number of paths and less than the number of connection signals; when the number of paths is greater than the number of connection signals and the number of paths is a multiple of the number of connection signals, optical signals corresponding to a second set number of light source devices can be accessed to a second device, and the second set number can be smaller than the number of connection signals; when the number of paths is less than the number of connection signals and the number of connection signals is not a multiple of the number of paths, the optical signals corresponding to each light source device on the first board may be grouped according to the number of connection signals, that is, the number of optical signals included in each group is equal to the number of connection signals. When grouping, the number of optical signals corresponding to one light source device in each group is at least two, so as to ensure that the number of light source devices corresponding to optical signals accessed to each second single board is smaller than the number of connection signals between the first single board and each second single board, and optionally, optical signals corresponding to the same light source device are located in the same group or adjacent groups; and under the condition that the number of paths is greater than the number of the connection signals and the number of paths is not a multiple of the number of the connection signals, the number of the laser devices corresponding to the optical signals contained in one group is less than or equal to the number of the connection signals. For example, a certain number of groups are first divided from each light source device, and then the remaining light signals in each light source device, i.e., the light signals that are not grouped, are rearranged and grouped, so that the light signals corresponding to one light source device can be adjacent when grouped. The value of the certain number may be the quotient of the number of paths divided by the number of signals.

Based on the number of paths and the number of connection signals, a corresponding relationship between each light source device and each second board may be determined, and based on the corresponding relationship, a connection between the first board and the second board may be established on the optical backplane.

In an embodiment, when the number of paths is equal to the number of connection signals, all optical signals corresponding to one optical source device on the first single board are connected to one second single board, and the optical source devices corresponding to the second single boards are different optical source devices;

when the number of paths is smaller than the number of connection signals and the number of connection signals is a multiple of the number of paths, all optical signals corresponding to a first number of light source devices on the first single board are accessed to a second single board, where the first number is a quotient of the number of connection signals divided by the number of paths, and the first number of light source devices corresponding to each second single board are different light source devices;

when the number of paths is greater than the number of connection signals and the number of paths is a multiple of the number of connection signals, a part of optical signals in optical signals corresponding to one light source device on the first single board are accessed to a second single board, the number of the part of optical signals is the number of connection signals, and the part of optical signals corresponding to each second single board are different;

and when the number of paths is greater than the number of connection signals and the number of paths is not a multiple of the number of connection signals, or when the number of connection signals is greater than the number of paths and the number of connection signals is not a multiple of the number of paths, grouping the optical signals corresponding to each light source device on the first single board according to the number of connection signals, and then respectively accessing the optical signals to each second single board, wherein the number of optical signals corresponding to one light source device in each group is at least two.

When the number of paths is equal to the number of connection signals, all optical signals corresponding to one optical source device may be connected to one second board, and the optical source devices corresponding to the second boards are different optical source devices, so that the optical source device corresponding to the non-in-place second board or the corresponding modulator may be turned off when the non-in-place second board exists in each second board. According to the present application, one light source device corresponds to one second single board, so that the light emitting power of the corresponding light source device can be adjusted based on the loss information of the optical signal in each second single board.

When the number of paths is less than the number of connection signals, and the number of connection signals is a multiple of the number of paths, all optical signals corresponding to the first number of light source devices on the first board are accessed to one second board, that is, one second board corresponds to the first number of light source devices. The first number is a quotient of the number of connection signals divided by the number of paths, and the first number is smaller than the number of connection signals.

When the number of paths is greater than the number of connection signals and the number of paths is a multiple of the number of connection signals, a part of optical signals in optical signals corresponding to one light source device on the first board are accessed to one second board, the number of the part of optical signals is the number of connection signals, and which optical signals are accessed to this point is not limited.

In order to reduce the number of the light source devices corresponding to the second board, the light signals corresponding to the light source devices may be grouped according to the number of the connection signals, and the number of the light signals corresponding to one light source device in each group is at least two.

It should be noted that, in the present application, only a connection manner between one first board and at least two second boards is shown, and a connection manner between a plurality of first boards and at least two second boards may refer to a connection manner between one first board and at least two boards, which is not limited herein.

The status information is not limited herein as long as the operating status of the first board can be controlled based on the status information, for example, the status information may be loss information of the optical signal and/or status information of the second board in place. The on-site status information may identify whether the second board is operating.

Different state information may correspond to different obtaining means, which is not limited herein, for example, the intensity information measured by the photodetector may be obtained, and the optical signal loss information may be determined based on the intensity information and the intensity information of the optical signal output by the first single board.

The control method of the present application may be applied to the switching device described in the present application, where the number of the light emitting devices corresponding to the second board in the present application is less than the number of the connection signals, and for example, one second board may correspond to one light emitting device when the number of the paths is equal to the number of the connection signals. Therefore, the present application can directly control the working state of the first single board based on the in-place state of each second single board, and specifically, the present application can directly turn off the light source device and the modulator corresponding to the second single board which is not in place; or based on the loss information of the second single board corresponding to the one light source device, adjusting the light emitting power of the light source device to reduce the loss of the second single board corresponding to the light source device.

The working state of the first single board can be controlled directly based on the optical power information, or after the optical signal loss information is determined based on the optical power information, the working state of the first single board is controlled based on the optical signal loss information. When the working state of the first single board is directly controlled based on the optical power information, the manner of adjusting the light-emitting device can be determined by comparing the obtained optical power information with the power information of the optical signal output by the first single board, and the adjusting means includes one or more of the following: reducing the luminous power, increasing the luminous power and maintaining the luminous power.

The method and the device can respectively determine the optical power information corresponding to the second single boards included in the switching equipment, and then determine the loss information corresponding to each second single board. And then controlling the working state of the light source equipment of the first single board based on the loss information and the preset information. Specifically, the present application may determine a maximum value of the loss information of the second single board corresponding to one light source device, and compare the maximum value with preset information to determine a working state of the light source device corresponding to the first single board, such as a magnitude of the light emitting power.

It should be noted that, in the switching device of the present application, a predetermined correspondence relationship exists between the light source device and the modulator in the first board and the second board. The corresponding relationship may be determined based on a connection manner of the first board and the second board of the switch device, which is not described herein again. One light source device may correspond to at least one second veneer.

The target light source device is a light source device in which none of the second veneers corresponding to the non-positioned second veneers is positioned.

The following is an exemplary description of the present application, which relates to an optical backplane-based switching device.

The appearance of the optical backplane promotes the requirement of the light-emitting unit inside the single board, fig. 3 is a schematic structural diagram of the single board provided by the present application, and referring to fig. 3, on a service board or a switch board 3 inside the switch device, units including a laser, an optical splitter, a modulator, a backplane connector, and the like are included. The service board or the switch board 3 may be considered as a single board in the switch device, such as the first single board or the second single board. The laser, the optical splitter and the modulator may be partially or completely integrated inside a certain chip (such as a silicon optical chip, etc.), and 1 or more such chips may be present on a single board. And 1 chip corresponds to at least 1 multi-path optical signal output by the laser. In order to reduce the number of light emitting units (i.e., lasers or light source devices), an optical splitter is used to split light emitted by a laser into multiple paths, which are sent to multiple modulators, respectively, and then a service processing unit or a service switching unit outputs data to the modulators, so that the data is loaded onto the light to form multiple paths of optical signals. The multiple optical signals are sent to the optical backplane via 1 or more backplane connectors.

Fig. 4 is a schematic connection diagram of a switching device provided in the related art, where a backplane connector inputs and outputs optical signals, and optical signal connection between a single board and other single boards through an optical backplane is implemented. In order to realize optical connection between boards, the multiple paths of optical signals dropped by the optical splitter may be sent to multiple opposite boards, regardless of the actual requirement of multiple optical connections at both ends. Referring to fig. 4, there are 4 optical connections between a left board (e.g., a service board) and a right board (e.g., a switch board), but when an optical path is arranged on an optical backplane, 4 optical paths separated by a certain laser on the left board are sent to 4 right boards, so that 4 such laser combinations are required to implement 4 optical connections between the left and right boards as a whole. Thus, if some 1 to 3 right single plates are not in place, but only one single plate on the right side works in place, any one laser cannot be turned off. Thus, the power consumption of the board cannot be sufficiently reduced. An "X1" in FIG. 4 may indicate that there is one optical connection.

In order to reduce power consumption on the single board, the idle functional units are turned off, or the light emitting power of the laser is reduced as much as possible, the laser is turned off as much as possible or the light emitting power of the laser is reduced as much as possible, and energy conservation and emission reduction of the sub-rack equipment comprising the first single board and the second single board in the exchange equipment are achieved. The method and the device effectively reduce the power consumption on the single board and achieve the purposes of energy conservation and emission reduction. The problems of power supply difficulty, heat dissipation difficulty and the like caused by overlarge power consumption of a single board in the switching equipment are effectively solved.

Fig. 5 is a schematic connection diagram of the switching device provided in the present application, and referring to fig. 5, the switching device may connect the service board and the switch board through the optical backplane, and backplane connectors are disposed on the optical backplane, the service board, and the switch board. The sub-frame device comprises at least one service board and at least one exchange board, which are respectively represented by a single board A and a single board B, and at least one optical back board is arranged between the service board and the cross board. At least 1 backplane connector is arranged between the veneer A and the optical backplane and is used for transmitting optical signals between the veneer A and the optical backplane; at least 1 backplane connector is arranged between the veneer B and the optical backplane and is used for transmitting optical signals between the veneer B and the optical backplane. The backplane connector can be a plurality of physical connectors, and the backplane connector internally comprises I combined units of L1M1-M and L2M1-M. Each of the combining units LiM1-m is an m-channel optical signal generated by m-channel modulation of the light output by the laser Li, and is LiM1 and LiM2. The board a1 and the board Aa may be service boards or switch boards, and the corresponding board B1 and the board Bb may be switch boards or service boards.

The light output by the same laser on one type of single board A (such as a service board or a switch board) is modulated and then output m paths of optical signals, and the m paths of optical signals are connected to at least one other type of single board B (such as a switch board or a service board) through an optical back board. Veneer a includes veneer a1 and veneer Aa. Veneer B includes veneer B1 and veneer Bb. In the present application, a single board a1 is used to describe the connection manner between the single board a and the single board B, and the connection manner between the single board Aa and the single board B can be referred to as the connection manner between the single board a1 and the single board B, which is not limited herein.

If there are k pairs (1 pair is 1 receiving and 1 sending) of connection signals between a single service processing unit or a service switching unit on the board a and the opposite end board B, then:

if m is less than k, all m optical signals of part LiM1-m are connected to a certain single board B, and all or part of LjM1-m optical signals on the same single board are scattered and respectively connected to the single board B; wherein 1-m is 1, 2, 3.

Where m may be understood as the number of paths described herein, and k may be understood as the number of connection signals described herein. The veneer a may be understood as a first veneer in this application, and the veneer B may be understood as a second veneer in this application. When the connection between the board a and the board B is established, there may be optical signals (e.g., m optical signals of LiM1-m, where i is a different value) corresponding to part of the optical source devices all connected to the board B, and there may be optical signals (e.g., LjM1-m optical signals, where j may take a different value) corresponding to part of the optical source devices partially connected to the board B, so as to ensure that the number of the optical source devices corresponding to the optical signals connected to each second board is less than the number of the connection signals between the first board and each second board.

If m is k, all m optical signals of LiM1-m are connected to one single board B;

if m is larger than k, splitting the m optical signals of the LiM1-m according to every k optical signals, respectively connecting the split optical signals to the single board B, and combining the last remaining optical signals smaller than k with the remaining optical signals smaller than k on the other LjM 1-m; or the last remaining less than k optical signals are combined with LjM1-m optical signals. And splitting and connecting to other single boards B according to the method. Wherein i ≠ j, which are positive integers.

Therefore, the connection of all optical signals on the board a to all boards B is realized. Based on the same mode, the connection from all optical signals on the board B to all boards a can be completed.

On the optical backplane, when multiple paths of optical signals output by the same laser are transmitted between 2 backplane connectors or more than 2 backplane connectors, the wiring length of the optical signals is kept within a certain difference range, so that the difference of optical power insertion loss among the optical signals is reduced. For example, in the optical waveguide backplane, the size deviation of the loss of m optical signals output by the same laser propagating on the optical waveguide backplane is less than 2dB or other values.

Fig. 6 is a schematic diagram of another connection of the switching device provided in the present application. Referring to fig. 6, light emitted from the laser Li on the single plate a is divided into 4 paths for optical modulation, i.e., m is 4. And one chip in the single board a and the single board B have 4 pairs of signals to be connected, and k is 4. Wherein, m is k, and all 4 optical signals, i.e. LiM1-m, are connected to the same board B, so that the connection from the board a to the board B is realized. At this time, the 4 optical signals of LiM1-m do not need to be separately connected to different boards B.

Fig. 7 is another connection diagram of the switching device provided in the present application. Referring to fig. 7, light emitted from the laser Li on the single plate a is divided into 4 paths for optical modulation, i.e., m is 4. And one chip in the single board a needs to be connected with 2 pairs of signals on the single board B, k is 2, where m > k, and part of 4 optical signals LiM1-m are split according to every 2 and are respectively connected to the single board B, and finally, no remaining optical signals are combined with the remaining optical signals smaller than k on the other LjM 1-m. Thus, the connection from the single board A to the single board B is realized. At this time, the 4 optical signals LiM1-m do not need to be split and connected to 3 or 4 boards B, and only splitting and connecting to the board B according to 2 is needed.

The control method of the present application may include:

if m paths of optical signals output by a certain laser do not have a single plate at the opposite end connected through the optical back plate, the laser and/or a related modulator and the like are closed;

if m paths of optical signals output by a certain laser are all or partially in place on an opposite end single plate connected through an optical back plate, but the optical power of the connected paths which are not more than m paths at the receiving end of opposite end equipment is larger, namely the insertion loss of a connecting line is smaller, the luminous power of the laser is reduced; (not all m paths are required to be connected to the same opposite end board, and all opposite end boards are in place.)

If m paths of optical signals output by a certain laser, all or part of the opposite end single plate connected through the optical back plate has the single plate in place, and the optical power of the m paths of optical signals at the receiving end of the opposite end equipment is not more than the acceptable proper range, the luminous power of the laser is kept.

Specifically, for each laser, the on-position state and the optical power of the corresponding second board are detected, that is, the on-position state and the optical power of the receiving end of the second board are detected. The detection result is then sent to a control unit, such as a processor in the terminal device, which calculates the maximum optical signal loss in the connected optical path and controls the laser and/or modulator based on the detection result and/or optical signal loss. The method and the device can control the on and off of the laser and can also control the light emitting power of the laser. The present application may control the turning on or off of the modulator.

If the second single plate corresponding to the laser is not in place, the laser and the modulator can be turned off. If the optical signal loss of the second single plate corresponding to the laser, that is, the loss information, is smaller than the preset information, the light emitting power of the laser can be reduced. If the optical signal loss of the second single plate corresponding to the laser is larger than the preset information, the light emitting power of the laser can be increased.

The control method described in this application may be integrated on a control unit (such as a processor) of a main control board of the switching device, or may be integrated on a control unit of a first board or a second board of the switching device. The main control board can control each single board in the switching device, and can also detect the in-place state information of each single board in the switching device.
