Background
Currently, incoming traffic from an ethernet interface in a network device may come from multiple flows, and in order to monitor the traffic of each flow, statistics on the number of messages and bytes of each flow are necessary in the device. Since the number of flows supported by the network device is generally large (generally 1M and above), a Double Data Rate (DDR) device with a large capacity is selected as a storage device for the flow statistics of each flow in most cases. DDR requires that when accessing an address within it, the row corresponding to Bank is activated first, and then a read/write command is sent to a column in the row after waiting for tRCD time. If the read-write command is sent alternately, the tRCW needs to be kept between the read command and the write command, namely, the interval of read-write conversion time; the write command also needs to maintain tttr, i.e., the interval of write-read transition time, from the read command. Because the physical characteristics of DDR devices require that a fixed interval be maintained between the alternating transmission of read and write commands, which can slow down the execution rate of the write statistics service, the problem of how to increase the execution rate of the write statistics service needs to be solved.

In the present embodiment, tRTW represents the read-to-write delay, the time that must be waited between the last valid read operation and the next write operation.
In the related art, when traffic of a certain flow is counted, information sent by a network device to a DDR controller is an increment of a statistic value. Therefore, the original statistic value needs to be read from the DDR equipment, the increment of the statistic value is increased on the basis, and finally the DDR equipment is written back, so that the write-once statistic service can be considered to be executed after the series of operations are completed. This is a read-write operation, as can be seen from the operation content.

Then, whether the read data exceeding the preset number of DDRs is returned can be detected, when the number of the read data exceeding the preset threshold is not exceeded, whether the next service is the writing statistical service is detected, and when the next service is the writing statistical service, the steps S1-S3 can be repeatedly executed to realize continuous and repeated reading operation, so that the continuous and repeated writing operation can be carried out after the continuous and repeated reading operation is carried out when the writing statistics is executed, the occurrence frequency of the DDR reading-writing conversion time can be reduced to the greatest extent on the premise of ensuring the accuracy of the statistical data, the execution rate of the writing statistical service is improved, and the rate of the statistical service is also improved. Namely, on the premise of ensuring the accuracy of the statistical data, the reading operation and the writing operation in the statistical business reading and writing operation are continuously carried out.
Optionally, the method further comprises the following steps:
when the number of the returned DDR read data exceeds the preset threshold value, the data enters a writing state, and the accumulated data is completely written back to the DDR according to the reading sequence in the reading state so as to realize continuous and repeated writing operation.
In this embodiment of the present application, when the number of the returned DDR read data exceeds a preset threshold, a write state may be entered, and the accumulated data may be completely written back to the DDR according to the order of reading in the read state. Specifically, after the DDR read data is returned, the DDR read data is added with the statistics value increment sent by the user and is stored in a first-in first-out queue (First in First out, FIFO) until the DDR read data enters a writing state, so that the write operation is continuously performed for a plurality of times, namely, the final statistics value is written back to the DDR according to the reading sequence.
Optionally, the method further comprises the following steps:
and when the next service is not the writing statistical service, entering a waiting state, waiting until the data return quantity of the DDR exceeds the preset threshold, executing the step of entering a writing state when the data return quantity of the DDR exceeds the preset threshold, and completely writing the accumulated data back to the DDR according to the reading sequence in the reading state.
In this embodiment of the present application, when the next service is not a write statistics service, a waiting state may be entered, waiting until the number of data returned by the DDR exceeds a preset threshold, and executing the step of entering a write state when the number of data read by the DDR that has been returned exceeds the preset threshold, and fully writing the accumulated data back to the DDR according to the order of reading in the read state, that is, after the data read by the DDR returns to exceed the preset threshold, adding the accumulated data increment with the statistics value sent by the user and storing the added data increment in a first-in first-out queue until entering the write state, and writing the final statistics value back to the DDR according to the order of reading.
Optionally, the electronic device includes a cache, and the method further includes:
comparing the input address with addresses in a preset address set in the cache, wherein the preset address set comprises at least one address; when the input address is different from any one of the preset address sets, a read instruction corresponding to the input address is sent to the DDR, the input address is written into the preset address set, and the statistical increment value corresponding to the input address is written into a preset data set.
The preset address set may be stored in advance or default to the system. The set of preset addresses may include at least one address.
In this embodiment of the present application, the input address may be compared with an address in a preset address set in the cache, where the preset address set includes at least one address, and when the input address is different from any one address in the preset address set, a read command corresponding to the input address is sent to the DDR, and the input address is written into the preset address set, and the input statistical increment value is written into the preset data set.
Optionally, the method further comprises the following steps:
when the input address is the same as a target address in the preset address set, not sending the read command to the DDR, and inquiring target data in the preset data set corresponding to the target address, wherein the target address is any address in the preset address set; reading the target data; adding the target data to the statistical added value corresponding to the input address to obtain a target statistical added value; when the DDR data returns, the corresponding return data is added with the target statistical value obtained by the target statistical increment value and stored in a first-in first-out queue; in the write phase, the target statistics are written back to the DDR.
The preset data set may include at least one data, and each data may correspond to an address.
In this embodiment, when the input address is the same as the target address in the preset address set, it is indicated that the situation that the addresses are the same occurs in the continuous reading process in the reading stage, the target data in the preset data set corresponding to the target address can be queried without sending a read command to the DDR, the target address is any address in the preset address set, the target data is read again, the target data is added with the statistical increment value corresponding to the input address to obtain the target statistical increment value, when the DDR data is returned, the target statistical value obtained by adding the corresponding return data with the target statistical increment value is stored in the first-in first-out queue, and in the writing stage, the target statistical value is written back to the DDR.
Specifically, in the embodiment of the present application, if the addresses are the same during the continuous reading in the reading stage, the same data may be read out by two reading operations with the same address, so that the last written-back data covers the last written-back data, and the statistical data error is caused. To avoid this, the write statistics requests for the same address may be consolidated.
In the specific implementation, a buffer memory of the address read in the reading stage is maintained in the reading stage, when a new request of a user arrives, firstly, the address attached to the request is compared with the address in the buffer memory, if the comparison is passed, the address corresponding to the preset data set for storing the data is read, the data in the buffer memory is read and rewritten, the statistical increment of the time is added on the basis of the original data, and the original address is rewritten.
For example, as shown in fig. 2, in the embodiment of the present application, the service is write statistics, and according to the address of the user, reading is performed on the address corresponding to the DDR, and whether the number of the read data of the DDR that has been returned exceeds a preset threshold value is detected; if not (N), detecting whether the next service is the writing statistical service.
If yes, executing a step of executing one reading of the address corresponding to the DDR according to the address of the user; if not (N), entering a waiting state, and waiting until the data return quantity of the DDR exceeds a preset threshold value.
Detecting whether the quantity of the returned DDR read data exceeds a preset threshold value; if yes, entering a writing state, and writing all accumulated data back to the DDR according to the reading sequence in the reading state. In the waiting stage, if and only if the quantity of returned read data corresponding to the read command sent in the reading stage exceeds a preset threshold value, the read data can enter a writing state after being added with the statistical increment input by the user and stored in the corresponding FIFO. Otherwise, insufficient data may be encountered in the write state.
Next, it is detected whether the next service is a write statistics service; if yes, executing a step of executing one reading of the address corresponding to the DDR according to the address of the user; if not (N), executing other services.
In the specific implementation, after the DDR read data is returned, the DDR read data is added with the statistic value increment sent by the user and stored in the first-in first-out queue until the DDR read data enters a writing state, and the final statistic value is written back to the DDR according to the reading sequence.
Further, in the embodiment of the present application, in order to avoid address collision during reading and writing, the user's write statistics requests for the same address are combined. In a specific implementation, the DDR can be continuously read, and the read-write request is based on the data read back from the DDR, and the DDR is written back after the data is added with a statistic increment. If the addresses are the same during the continuous reading of the read phase, it may result in two read operations with the same address reading the same data, thereby resulting in the last write-back data overlapping the previous write-back data, resulting in a statistical data error. To avoid this, the user's write statistics requests to the same address are consolidated.
By way of example, as shown in FIG. 3, the input address may be referred to as addr and the addresses in the cache may include: addr_buffer_0, addr_buffer_1, addr_buffer_2, …. The input address can be compared with the address in the cache, if any address in the cache is the same as the input address, the address in the Data cache corresponding to any address in the cache can be obtained and recorded as data_buffer_1, the corresponding Data can be obtained, the Data can be read out, the Data attached to the user request is added on the basis, the Data is written back to the Data cache, and finally the Data is written back to the DDR in the writing stage.
In the specific implementation, the address requested by the user is compared with the address in the cache first, if and only if the requested address is different from the address in the cache, the requested address is written into the cache, if the requested address is the same as any address in the cache, the corresponding Data (Data) in the Data RAM is found according to the address in the cache, the Data is read out, the Data attached to the user request is added on the basis, then the Data is written back into the Data RAM, the final statistical value can be obtained after the Data corresponding to the DDR is added after the Data is returned, and finally the Data is written back into the DDR in the writing stage.
In the embodiment of the application, the write operation is continuously performed for a plurality of times after the read operation is continuously performed for a plurality of times when the write statistics is performed, so that the occurrence frequency of DDR read-write conversion time is reduced to the greatest extent on the premise of ensuring the accuracy of the statistical data, and the speed of the statistical service is improved.
The statistical service execution rate improving method described in the embodiment of the present application is applied to electronic equipment, where the electronic equipment includes a DDR, and when the current service is a write statistical service, the following steps S1 to S4 are executed: s1, acquiring an input address, determining a storage address in the DDR corresponding to the input address, and executing a read operation on the storage address; s2, detecting whether the quantity of the returned DDR read data exceeds a preset threshold value; s3, when the number of the returned DDR read data does not exceed a preset threshold value, detecting whether the next service is a writing statistical service or not; and S4, when the next service is the writing statistical service, executing the steps S1-S3 to realize the continuous and repeated writing operation after the continuous and repeated reading operation, so that the continuous and repeated reading operation can be performed when the writing statistics is performed, the occurrence frequency of the DDR reading-writing conversion time can be reduced to the greatest extent on the premise of ensuring the accuracy of the statistical data, the execution rate of the writing statistical service is improved, and the rate of the statistical service is also improved.
