in this step, determining a forwarding manner of the data to be forwarded according to the rate of the target sending port and the rate of the receiving port of the data to be forwarded includes:
and determining the forwarding mode of the data to be forwarded by comparing the speed of the target sending port with the speed of the receiving port of the data to be forwarded. The method for determining the forwarding mode may be set according to actual requirements, for example, when the rate of the receiving port is greater than or equal to the rate of the target sending port, a direct forwarding mode is adopted, and when the rate of the receiving port is less than the rate of the target sending port, a store-and-forward mode is adopted. Therefore, under the condition that ports with different rates exist in the network, data forwarding between ports with the same rate or between ports with high rate and low rate is directly forwarded, and the delay performance of forwarding is ensured; for the forwarding from a low-speed port to a high-speed port, the continuity of forwarding data at an output port is ensured by adopting a storage forwarding mode; moreover, through the self-adaptive switching of the forwarding mode, different switches are not needed to meet the requirements of various indexes in a complex scene, and the application cost of the equipment is reduced.
Taking the port rate support of 1/2/4 Gbps as an example, the method for determining the forwarding mode of the present invention is described, and the determination results of the forwarding mode at different port rates are shown in table 1.
TABLE 1
As can be seen from table 1, in the existing hybrid network composed of coaxial (maximum rate 1 Gbps) and optical fiber (maximum rate 4Gbps), it can be ensured that transmission between optical fiber ports is directly forwarded, thereby ensuring transmission efficiency of FC (fiber Channel, optical fiber interface) messages; meanwhile, the transmission from the coaxial interface to the optical fiber interface is stored and forwarded, so that the accuracy of data transmission between the coaxial interface and the optical fiber interface is ensured.

By the mode, the data to be forwarded is ensured to be written into the storage module, namely, the data can be read and forwarded by the target sending port, and the requirement of direct forwarding is met.
And under the condition that the determined forwarding mode is store-and-forward, the forwarding time is determined according to the stored data volume of the data to be forwarded. The implementation method for determining the forwarding time of the data to be forwarded according to the received data amount of the data to be forwarded may be set according to actual needs, for example: determining the forwarding time of the data to be forwarded according to the time when the stored data volume of the data to be forwarded reaches a preset threshold value; the preset threshold is obtained according to the rate of the target sending port and the rate of the receiving port of the data to be forwarded. Another example is: and determining the forwarding time of the data to be forwarded according to the time for completely storing the data to be forwarded.

T=L*Vo/(Vi+Vo) （1）
wherein, T is a preset threshold value, L is the maximum frame length of the data to be forwarded, and ViFor receiving the rate of the port, VoThe rate of the destination transmit port. That is, the time when the length of data written into the memory module reaches T, where T is an integer multiple of 4 bytes, is determined as the forwarding time. Taking the port rate support of 1/2/4 Gbps as an example, the method for determining the preset threshold value of the present invention is described, and the preset threshold values calculated by equation (1) for different port rates are shown in table 2.
TABLE 2
The calculation results of the preset threshold values in table 2 are all integer multiples of 4 bytes.
The forwarding time of the data to be forwarded is determined through the preset threshold, and the delay of data forwarding can be reduced to the greatest extent on the premise of meeting the data transmission continuity of the sending port.
And S304, after the data to be forwarded is forwarded, repeating the steps from S100 to S300, and forwarding the next frame data.

s404, receiving an FC frame through FC2P of a current receiving port, converting the FC frame into a data STREAM of an AXI-STREAM interface, and sending the data STREAM to an S _ IPPM; s _ IPPM extracts destination ID information in a frame header, applies for a storage address (ADDR _ REQ) and routing information of a current FC frame in Data _ sw to Route _ management according to the destination ID information, and determines a target sending port of the current FC frame according to the routing information;
s405, after the S _ IPPM obtains a target sending port, determining a forwarding mode according to the table 1 according to the rate values of the current receiving port and the target sending port, if the forwarding mode is direct forwarding, jumping to a step S406, and if the forwarding mode is store forwarding, jumping to a step S407;
s406, the current mode is a direct forwarding mode, FC frame Data is written into Data _ sw through S _ IPPM according to an applied storage address, in order to ensure that Data can be directly forwarded, the applied storage address and port information of a target sending port are sent to H _ crossbar, the H _ crossbar forwards the storage address to S _ OPPM of a corresponding port according to the port information of the target sending port, the S _ OPPM reads the FC frame cached in the Data _ sw according to the storage address, and the FC frame Data is sent out through FC2P of the target sending port; after the S _ OPPM is read, sending a signal (ADDR _ release) for releasing the storage address to Route _ management, so that the occupied storage space can be applied again, and repeating step S403 to forward the next FC frame; because the reading of the S _ OPPM in the target sending port and the writing of the S _ IPPM in the receiving port are carried out simultaneously, no time is wasted, and the requirement of direct forwarding is met;
s407, currently, in a store-and-forward mode, writing FC frame Data into a Data _ sw through an S _ IPPM according to an applied storage address, in order to reduce delay and ensure Data continuity of store-and-forward, when the Data volume written into the Data _ sw reaches a threshold value or Data writing is finished, sending the applied storage address and port information of a target sending port to an H _ crossbar, forwarding the storage address to an S _ OPPM of a corresponding port according to the port information of the target sending port by the H _ crossbar, reading an FC frame cached in a Data _ sw module according to the storage address by the S _ OPPM, and sending the FC frame Data out through an FC2P of the target sending port; after the S _ OPPM is read, sending a signal (ADDR _ release) for releasing the storage address to Route _ management, so that the occupied storage space can be applied again, and repeating step S403 to forward the next FC frame; for example, a port 0 (rate: 1 Gbps) performs store-and-forward to a port 1 (rate: 4Gbps), the length of the FC frame is 2112 bytes, and when the FC frame is written into 1692 (four fifths of 2112 and increased to an integral multiple of 4), the applied storage address and the port information of the target transmission port are sent to H _ crossbar, thereby effectively reducing the forward delay on the premise of ensuring the continuity of data forwarding.
