step 101: and in the hot backup processing process of the switch, forwarding the data frame sent by the media access controller to the physical interface transceiver based on a preset data distribution module.
Specifically, the Switch (FC) is a high-speed network transmission relay device. In the embodiment of the present invention, during the hot backup processing of the switch, a data frame sent by a media access controller may be acquired at a front segment of the media access controller based on a preset data splitting module through a Field Programmable Gate Array (FPGA) chip, and the data frame is forwarded to a physical interface transceiver, that is, full-byte redundancy removal comparison processing is performed between the media access controller and the physical interface transceiver, so that a high-speed parallel characteristic is improved, the redundancy removal time is reduced, the forwarding delay is reduced, and the hot backup processing of the switch can be implemented only by one media access controller in a specific implementation process. The Media Access controller refers to a Media Access Control (MAC) chip of the ethernet card, and the Physical interface transceiver refers to a Physical layer (PHY) chip of the ethernet card.
Step 102: and receiving two paths of signals obtained by encoding of the physical interface transceiver based on a preset hot backup redundancy processing module, and performing full-byte redundancy removal comparison processing on the two paths of signals based on the hot backup redundancy processing module to obtain target data after redundancy processing.
In the embodiment of the present invention, the hot backup redundancy processing module performs full-byte redundancy removal comparison processing on the two paths of signals to obtain target data after redundancy processing, and the specific implementation process includes: forwarding a first path of signals to a first bit width conversion module based on a first interface preset in the hot backup redundancy processing module, and performing bit width conversion on the first path of signals based on the first bit width conversion module to obtain a first path of data frame to be transmitted; recording and caching the first path of data frame based on a preset first receiving caching module; forwarding a second path of signals to a second bit width conversion module based on a second interface preset in the hot backup redundancy processing module, and performing bit width conversion on the second path of signals based on the second bit width conversion module to obtain a second path of data frames to be transmitted; recording and caching the second path of data frame based on a preset second receiving and caching module; based on a preset full-frame comparison and port comparison mode, repeatedly identifying the first receiving cache module or the second receiving cache module with historical data recorded by the repeated data identification module respectively, and storing a target data frame meeting a preset condition after repeated identification to a data recovery cache module; and performing bit width conversion processing on the stored target data frame by using a preset bit width recovery module to obtain target data subjected to Ethernet hot backup redundancy processing. The two paths of signals comprise the first path of signals, the second path of signals and the like. The first interface and the second interface are both preset Gigabit media independent interfaces (GMII interfaces). The two paths of signals are obtained by encoding the converted serial stream data by the physical interface transceiver based on a preset encoding rule of a physical layer.
The target data frame which meets the preset condition after repeated identification is stored in the data recovery cache module, and the specific implementation process comprises the following steps: after repeated identification, analyzing whether a target data frame meeting a preset condition exists or not, and storing the data frame to a data recovery cache module when the data frame is determined to be different; when the data frame and the port are determined to be the same, storing the data frame to a data recovery cache module; and when the data frames are determined to be the same and the ports are not the same, the data frames are forbidden to be stored in the data recovery cache module. The data frames comprise a first path of data frame or a second path of data frame and data frames in historical data. And the data frame in the historical data is the data frame stored in the data recovery cache module.

The data frame to be transmitted by the media access controller is directly divided into two paths of identical data by a data splitting module (such as a one-to-two module) and transmitted to the physical interface transceiver 1 and the physical interface transceiver 2. And the physical interface transceiver 1 and the physical interface transceiver 2 acquire the data shunted by the data shunting module and then encode the data, and acquire two corresponding paths of signals through the hot backup redundancy processing module to perform full byte redundancy removal comparison processing, so as to obtain target data after redundancy processing.

The GMII interface in the figure is an exemplary interface adapted between the PHY chip and the MAC chip, but is not limited to using this type of interface. In a specific implementation process, the data frame from the GMII _ a module can be received and subjected to bit width conversion based on the first bit width conversion module; and the second bit width conversion module receives the data frame from the GMII _ B module and performs bit width conversion, so that data carrying processing of subsequent modules is facilitated. Receiving a data frame from the first bit width conversion module for bit width conversion based on the A-way cache, and caching; and receiving the data frame subjected to bit width conversion from the second bit width conversion module based on the B-path cache for caching. And comparing the cached data in the A-way cache or the B-way cache based on the repeated data identification module, and performing repeated identification on the data and the historical data of the query history record. And buffering the data frame when the full frame comparison is carried out based on the temporary data buffering module. And caching the data frames meeting the preset conditions after comparison by a data recovery-based caching module. And performing bit width conversion processing on the cache data based on the bit width recovery module to convert the cache data into the GMII data bit width.
Wherein, the whole-byte redundancy removal comparison processing flow specifically comprises: and after bit width conversion is carried out on the data received by each path, caching is carried out, and in order to match the bandwidth and reduce the delay, the bit width of the data can be properly increased. And repeatedly identifying the data received by the A-way cache or the B-way cache and the historical data of the query history record of the repeated data identification module by adopting a full-frame comparison and port comparison mode. Specifically, under the condition that the data frames are inconsistent, allowing the data frames to enter a data recovery cache module; under the condition that the port is consistent with the data frame, allowing the data frame to enter a data recovery cache module; and under the condition that the data frames are consistent and the ports are not consistent, the data frames are not allowed to enter the data recovery buffer module. Meanwhile, historical data are stored in the data sent to the data recovery cache module, each record adopts an independent storage space and a port identifier, a historical cyclic record is designed, and the historical storage can be updated after n frames. And finally, performing bit width conversion on the compared data to convert the compared data into the GMII data bit width.
