[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0028] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.

[0029] like Figure 1 As shown in the figure, a configurable multi-adaptive convergence and distribution switch based on FC is mainly composed of three parts: SPF fiber interface module, FPGA information exchange logic processing module, and FPGA+ARM control management module. The fiber interface module provides external interface functions and can communicate with external devices through optical modules; the FPGA information exchange logic processing module controls the information communication exchange logic between devices according to the switch configuration, including message aggregation and distribution; the control management module manages and controls the functions, status, and configuration of the entire switch. The modules are in series, such as: SPF fiber interface module <=> FPGA information exchange logic processing module <=> FPGA+ARM control management module.

[0030] The FC aggregation and distribution switch is developed and produced based on FPGA programmable logic processing chips. In addition to meeting the functions and characteristics of traditional switches, the switch can also customize different information exchange logic according to the place of use or environment. At the same time, the switch has an Ethernet port for managing the configuration information of the switch, such as aggregation, distribution port grouping, DID configuration, etc.; the serial port is used to debug and manage the switch.

[0031] First, different processing logics are formulated according to the network environment, and the FGPA is logically solidified to adapt to the current network environment. The user then configures the required ports through the Ethernet port, such as aggregation ports, distribution ports, monitoring ports, debugging ports, etc. Finally, the switch exchanges network information according to the user configuration, thereby realizing flexible and adaptable network switching capabilities.

[0032] like Figure 2 As shown in FIG. 1 , it is a switch aggregation logic diagram. The switch controls and manages the aggregation function of the switch through user configuration (including protocol format, DID, aggregation group, etc.) to achieve message aggregation requirements in different network environments.

[0033] The user can configure the aggregation of each port function of the switch through the device configuration management interface, including the aggregation input port and the aggregation port. The same device can be configured with multiple group aggregations. Figure 2 As shown, the messages of ports 1, 2, and 3 are aggregated to port 48, and all messages passing through ports 1, 2, and 3 are output through port 48, thereby realizing the aggregation and output function of messages from multiple ports.

[0034] like Figure 3 As shown in FIG. 1 , it is a switch distribution logic diagram. The switch controls and manages the distribution function of the switch through user configuration (including protocol format, DID, distribution group, etc.) to achieve message distribution requirements in different network environments.

[0035] The user can configure a unique identifier (DID) for each port of the switch, and the switch's logic processing (FPGA information exchange logic processing module) distributes the input message according to this identifier. The identifier in the message is matched with the identifier of the port. If the match is successful, the message is output from the port. Figure 3 As shown, the messages msg2, msg3, and msg48 received by port 1 are distributed to the output ports identified as 0x10002, 0x10003, and 0x100048, thereby realizing the message distribution and output function.

[0036] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
