Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating a possible structure of an expandable subrack device according to an embodiment of the present invention, where the possible structure may include:

a main control board 100, a switch board 200, a network input board 300, an output service board 400, and an intelligent service board 500. The main control board is used for controlling the exchange board. The network input board 300 may be used for outputting video data, the output service board 400 may be used for outputting corresponding service data to a downstream device, the intelligent service board 500 is used for providing a corresponding intelligent service, the intelligent service board 500 may be a motherboard of an X86 architecture, the provided intelligent service may be different according to different application scenarios, and according to different actual requirements of users in the application scenarios, the number of the network input board, the output service board, and the intelligent service board may be one or multiple, which is not limited in this embodiment.

The switch board includes a data switch chip 210, a control switch chip 220, a plurality of internal ports 230, and a plurality of external ports 240. The plurality of internal ports are respectively used for docking a network input board, an output service board and an intelligent service board. The plurality of external ports are used for inputting boards through a network, interfacing with an expansion device inserted into the expandable subrack device, and include a data port 241 and a control port 242 for the plurality of external ports.

And the data exchange chip is used for controlling the data port to realize data transmission in the expandable machine frame equipment. And the control exchange chip is used for controlling the control port to realize control instruction transmission in the expandable machine frame equipment.

With the embodiment, two special internal networks can be constructed inside the expandable machine frame device through different switch chips and external ports on the switch board, and are respectively used for transmitting data and control instructions inside the expandable machine frame device. Consequently, to the interaction that distributed expansion equipment such as output, input box on expanded frame equipment can be normal carry out data and control command with expanded frame equipment, promptly output, distributed expansion equipment such as input box can directly peg graft on expanded frame equipment, and need not to connect in expanded frame equipment through private exchange switching, use convenient and fast more.

In order to more clearly describe the extensible shelf device provided in the embodiment of the present invention, the following describes, in combination with different application scenarios, execution logic of each component in the extensible shelf device.

In a possible embodiment, the data exchange chip may divide the data ports into a first type of data port and a second type of data port, where the first type of data port and the second type of data port are isolated from each other, for example, the data ports may be divided into a 10G port and a 40G port, and in other optional embodiments, other dividing manners may also be used, which is not limited in this embodiment.

And video data transmission in the expandable machine frame equipment is realized through one type of data port in the first type of data port and the second type of data port. And intelligent data transmission inside the expandable machine frame equipment is realized through the other data port of the first class data port and the second class data port. For example, the video data transmission inside the expandable subrack device can be realized through a 10G port, and the intelligent data transmission inside the expandable subrack device can be realized through a 40G port. For example, video data transmission inside the scalable shelf device may be realized through the 40G port, and intelligent data transmission inside the scalable shelf device may be realized through the 10G port. The video data may include FPGA (Field-Programmable Gate Array) data after shallow programming of local streams and network streams. The intelligent data may include data resulting from an intelligent big data calculation.

The embodiment can be selected to respectively transmit the video data and the intelligent data by constructing two mutually isolated special networks, so that the video data and the intelligent data are prevented from colliding in the transmission process, and the stability and the efficiency of the equipment are improved.

The data ports may be divided according to the actual requirements of the user, or may be divided according to a preset rule. For example, referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for partitioning a data port of an extensible subrack device according to an embodiment of the present invention, where the method includes:

s201, the client displays the configuration interface of the switchboard.

The port identification of the data port available for configuration can be displayed in the switch board configuration interface. For example, assuming that there are ten data ports, and the ten data ports may be configured as a first-type data port or a second-type data port according to the needs of the user, port identifiers of the ten data ports may be presented in the switch board configuration interface, so that the user may input a corresponding operation instruction for each port identifier, respectively, where the operation instruction may be used to configure attribute information of the data port represented by the port identifier. The attribute information is used for representing the category of the data port. Illustratively, attribute information, which is classified as a first type of data port, is used to indicate that the data port belongs to the first type of data port.

S202, the client configures the attribute information of each data port according to the operation instruction input by the user.

S203, the main control board receives the attribute information of each data port sent by the client.

S204, the main control board obtains the current category of the data port, and determines whether the attribute information of the data port is consistent with the current category.

For example, for a data port a, the main control board may read the configuration file, determine that the category to which the data port a belongs currently is the first type of data port, and assuming that the received attribute information indicates that the data port a belongs to the first type of data port, it may be determined that, for the data port a, the attribute information is consistent with the category to which the data port a belongs currently. Assuming that the received attribute information indicates that data port a belongs to the second class of data ports, it may be determined that for data port a, the attribute information is inconsistent with the current class to which it belongs.

S205, the main control board forwards the attribute information inconsistent with the current category to the data exchange chip.

Suppose that a total of three attribute information are respectively recorded as attribute information a-C, where attribute information a indicates that data port a belongs to a first type of data port, attribute information B indicates that data port B belongs to a first type of data port, and attribute information C indicates that data port C belongs to a second type of data port. Suppose that the current class of data port a is the first type of attribute information and the current classes of data port B and data port C are the second type of attribute information. The main control board forwards the attribute information B to the data exchange chip.

S206, the data exchange chip receives the port attribute information sent by the main control board.

S207, the data exchange chip determines whether the current data port is classified, if so, S208 is executed, and if not, S209 is executed.

It is understood that if the current data port is not classified, the class to which each data port belongs may be recorded as none class, or may be recorded as a default class.

S208, the data exchange chip cancels the classification of the data port.

S209, the data exchange chip reclassifies the data ports according to the received attribute information.

In one possible embodiment, the data isolation may be performed by aggregating the first type of data port and the second type of data port into two different aggregation groups, respectively, and configuring the two different aggregation groups in different Virtual Local Area Networks (VLANs). To ensure the aggregation effect, when the network cable of any one port in the aggregation group is pulled out, the aggregation should be cancelled. Alternatively, when each port of the aggregation group has been plugged into the network wire, the port aggregation is refused to be cancelled, so as to prevent affecting the network topology of the expandable subrack device.

For example, referring to fig. 3, fig. 3 is a schematic flowchart of a dynamic management method for port aggregation in an extensible subrack device according to an embodiment of the present invention, where the method includes:

s301, the data exchange chip monitors whether the port connection state and the aggregation state of the aggregation group configured by the main control board are changed, if so, S302 is executed, and if not, S301 is repeatedly executed.

For example, assuming that the first type of data ports includes data port a and data port B, data port a and data port B may be aggregated in an aggregation group. If the aggregation of the data port a and the data port B is cancelled in the configuration parameters of the main control board, it may be determined that the aggregation state of the aggregation group configured by the main control board changes. If the network cable of the data port A and/or the data port B is detected to be pulled out, the port connection state can be determined to be changed.

The data exchange chip may periodically or aperiodically detect whether the connection state and the aggregation state of the aggregation group configured by the main control board change, if so, execute S302, and if not, detect again whether the connection state and the aggregation state of the aggregation group configured by the main control board change after a certain time interval.

S302, the data exchange chip judges whether the configuration parameter is to cancel the port aggregation, if so, S303 is executed, otherwise, S304 is executed.

Changes to the aggregation group may result, one may be to cancel port aggregation, and the other may be to enable port aggregation. For example, assuming that the aggregation group includes data port a, data port B, and data port C, port aggregation between data port a, data port B, and data port C may be cancelled, or a network cable inserted into data port C is pulled out, so that data port C can no longer continue port aggregation with data port a and data port B.

S303, judging whether the network connection of the data port of the aggregation group is cancelled to meet the condition, if so, executing S305, and if not, executing S306.

Wherein the condition may be different according to different application scenarios. For example, in one possible embodiment, if each data port in the aggregation group is connected with a network cable, port aggregation among the data ports is not allowed to be canceled, and if only part of the data ports in the aggregation group are connected with network cables, port aggregation among the data ports is allowed to be canceled. In another possible embodiment, if at least two data ports in the aggregation group are connected with a network cable, the aggregation between the data ports is not allowed to be cancelled, and if at most one data port in the aggregation group is connected with a network cable, the port aggregation between the data ports is allowed to be cancelled.

S304, judging whether the port of the enabled aggregation group changes, if so, executing S307, otherwise, executing S306.

Whether the port of the enabled aggregation group changes or not may be referred to in the related description in S302, and is not described herein again.

S305, according to whether the port of the canceling aggregation group changes, aggregation is configured.

If the aggregation-group port connection has not changed, then the de-aggregation is denied. The aggregation may be cancelled if no more than a preset number (in one possible embodiment, the preset number may be 1, and in other possible embodiments, the preset number may be other values according to actual requirements) of ports in the aggregation group are still connected.

S306, refusing to reconfigure the aggregation.

I.e. the port aggregation relationship between the current data ports is maintained.

S307, reconfiguring aggregation according to the number of the changed ports.

In one possible embodiment, it may be that if there is only one port or no port remaining in the aggregation group, the corresponding port aggregation is cancelled. If there are a plurality of remaining ports connected in the aggregation group, the plurality of remaining ports are re-aggregated. For example, assuming that the aggregation group includes data port a, data port B, and data port C, if data port a and data port B are not connected and only data port C is still connected, the port aggregation is cancelled. If the data port A and the data port B are still connected and the data port C is not connected, the aggregation is reconfigured to realize the port aggregation between the data port A and the data port B.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a possible network initialization flow of the extensible shelf device according to an embodiment of the present invention, and for convenience of description, the following description takes a network input board as an example, and includes:

s401, the main control board reads the intranet address of the exchange board and sends a first configuration instruction to the exchange board.

S402, the exchange board configures the network mode of the exchange board according to the first configuration instruction; multiple outbound ports are enabled.

And S403, the exchange board feeds back the first configuration result to the main control board.

Wherein, the first configuration result is used for indicating whether the switch board is successfully configured.

S404, the main control board determines whether the exchange board is configured successfully according to the first configuration result, if so, S405 is executed, and if not, S401 is returned to.

S405, the main control board reads the intranet address of the network input board and sends a second configuration command to the network input board.

S406, the network input board enables the communication function with the exchange board according to the second configuration command.

And S407, the network input board sends the second configuration result to the main control board.

Wherein the second configuration result is used for indicating whether the network input board configuration is successful.

S408, the main control board determines whether the configuration of the network input board is successful according to the second configuration result, if so, the initialization is finished, and if not, the process returns to the step S405.

It is understood that the principle of initialization may be the same for the output service board and the intelligent service board, and the difference may be only the difference between the configuration instruction sent by the main control board in S405 and the difference between the configuration result fed back in S408. For example, when the output service board is initialized, the configuration instruction sent by the main control board may be a third configuration instruction, and the configuration result fed back by the output service board is a third configuration result. When the intelligent service board is initialized, the configuration instruction sent by the main control board may be a fourth configuration instruction, and the configuration result fed back by the intelligent service board may be a fourth configuration result.

When loaded and executed on a computer, cause the processes or functions described in accordance with the embodiments of the invention to occur, in whole or in part. The computer may be a general purpose computer, a special purpose computer, a network of computers, or other programmable device.

The computer-readable storage medium can be any available medium that can be accessed by a computer or a data storage device, such as a server, a data center, etc., that incorporates one or more of the available media. The usable medium may be a magnetic medium (e.g., floppy Disk, hard Disk, magnetic tape), an optical medium (e.g., DVD), or a semiconductor medium (e.g., solid State Disk (SSD)), among others.
