All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second," and the like in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not set forth for a listed step or element but may include steps or elements not listed.
In an embodiment of the present invention, a pressure testing method for an FC-AE bus is provided, where the method corresponds to a pressure testing apparatus for an FC-AE bus provided in an embodiment of the present invention, and both of the methods are applied to a Programmable logic device (FPGA), and the FPGA is communicatively connected to a user control terminal and connected to a network or a device to be tested through the FC-AE bus, where the FPGA is communicatively connected to the user control terminal based on a communication interface thereof and connected to the network or the device to be tested through the FC-AE bus, and the FPGA may also be other electronic devices besides the FPGA, such as a Complex Programmable logic device (Complex Programmable logic L g device, CP L D), and the like, referring to fig. 1, the method may include the following steps:
and S101, obtaining test data through a user control terminal.
Here, connection between the user control terminal and the programmable logic device is described by taking an FPGA as an example, and the connection is performed through a communication interface of the FPGA, for example, the FPGA may complete information exchange with the user control terminal through an ethernet bus, a serial bus, a PCI (Peripheral Component Interconnect) bus, or a PCIE (Peripheral Component Interconnect express) bus, and the purpose of the information exchange is that the FPGA acquires test data through the user control terminal, receives flow control information from the user control terminal, and sends processing performance data to the user control terminal, and the like.
The test data is obtained through a user control terminal, and the specific obtaining mode is various. The following two ways are used for illustration:
first, first data generated by a user control terminal is received, the first data is directly used as test data, namely, a generation terminal of the test data is the user control terminal, and the first data generated by the user control terminal is directly used as test data to be sent to a programmable logic device for subsequent test work.
And secondly, receiving configuration information generated by the user control terminal, generating second data according to the configuration information, using the second data as test data, namely determining the configuration information corresponding to the configuration condition of the test data by the user control terminal, and then configuring the second data corresponding to the configuration information by the programmable logic device as the test data.
In the embodiment, the first mode is that the user control terminal generates test data in real time and transmits the test data to the programmable logic device, so that higher flexibility is realized; and the second mode is automatically generated by the programmable logic device according to the configuration information of the user, so that the efficiency is higher.
And S102, packaging the test data according to the data format of the FC-AE bus to obtain a message.
In order to enable the test data to be transmitted based on the FC-AE bus, the test data needs to be encapsulated according to the data format of the FC-AE bus, where the data encapsulation format of the FC-AE bus refers to the data format specification information corresponding to the FC-AE bus.
And S103, receiving the flow control information from the user control end, and transmitting a message to the FC-AE bus according to the flow indicated by the flow control information.
The programmable logic device can acquire the flow control information sent by the user control end through the communication interface to accurately control the flow of the FC-AE bus based on the flow control information so as to acquire the accurate pressure expected to be generated by the user control end in the current FC-AE bus. The flow indicated by the flow control information is determined by a user according to actual requirements, but the flow range indicated by the flow control information at least covers the flow range of the new generation of FC-AE bus in an actual application scene. For example, the flow rate control information indicates a minimum flow rate of zero and a maximum flow rate of the FC-AE bus of the new generation at the limit bandwidth. For another example, because the performance of the network or device under test can be guaranteed certainly when the traffic is small, and the maximum traffic in the actual application scenario does not reach the traffic in the limit bandwidth, the traffic indicated by the traffic control information may have a lower limit and an upper limit, where the lower limit corresponds to the minimum traffic that needs to be verified for the network or device under test, and the upper limit corresponds to the maximum traffic in the actual application scenario. In addition, although the embodiment of the invention is developed based on the verification requirement of a new generation FC-AE bus, the method and the device of the embodiment of the invention can also be applied to the performance verification of the FC-AE bus with smaller relative bandwidth.
In another embodiment of the present invention, a method for message transmission at a preset pressure (i.e., the precise pressure that the user control terminal is expected to generate) is also provided, in which there are two ways of generating pressure according to the characteristics of the FC-AE bus.
The first way is based on the format of idle words in the FC-AE bus, and the accurate control of the pressure can be realized by accurately controlling the idle words between the messages except for the 6 idle words inherent in the bus, that is:
determining the number of idle words among messages according to the flow control information and the format of the idle words in the FC-AE bus;
and combining the message with the idle words corresponding to the number of the idle words, and transmitting the combined message to an FC-AE bus.
The second mode is based on the percentage of the flow in the FC-AE bus, the bandwidth occupied by one message in the FC-AE bus is calculated according to the length of the message, and then the interval of two messages in the FC-AE bus is calculated according to the bandwidth, so that the pressure control is accurately realized, and the process of controlling the transmission of the message is as follows, corresponding to the second mode:
calculating and obtaining the bandwidth occupied by the message in the FC-AE bus according to the message length;
determining the interval of two messages in an FC-AE bus based on the bandwidth occupied by the messages in the FC-AE bus;
and transmitting the message to the FC-AE bus according to the interval.
S104, receiving feedback primitives fed back after the tested network or device obtains the message, and marking a time label for each received feedback primitive.
The message is transmitted through the FC-AE bus and then reaches the tested equipment or the network, and simultaneously receives a feedback primitive returned by the tested equipment or the network, wherein the feedback primitives and the message are in one-to-one correspondence, and when one message generated by the programmable logic device is sent to the tested equipment or the network through the FC-AE bus, one feedback primitive returned by the tested equipment or the network should be received. And the programmable logic device will mark a time tag for the feedback primitive at the first time when the feedback primitive is recognized, and the accuracy of the time tag is usually not less than 10ns in order to improve the statistical accuracy.
And S105, comparing the time labels on the adjacent feedback primitives to obtain the time interval between the adjacent feedback primitives.
And S106, calculating and obtaining the processing performance data of the tested network or equipment according to the time interval between the adjacent feedback primitives.
According to the received feedback primitives and the corresponding time labels thereof, the time intervals between two adjacent feedback primitives are compared, and the processing performance data of the tested device or the network under the current pressure can be calculated after statistical analysis, wherein the processing performance data can represent the processing time and the processing performance of the tested device or the network.
Correspondingly, in another embodiment of the invention, the processing performance data comprises a maximum value, a minimum value and an average value of a time interval between adjacent feedback primitives.
In practical applications, the processing performance data to be obtained may be processing time and processing performance of the network or device under test in different scenarios, and for this reason, in another embodiment of the present invention, step S106 may include: and carrying out statistical analysis on the time intervals between the adjacent feedback primitives in the time periods corresponding to different scenes to obtain the processing performance data of the tested network or equipment, wherein the processing performance data comprises the maximum value, the minimum value and the average value of the time intervals between the feedback primitives corresponding to the adjacent messages in each time period. In addition, in practical application, the time interval between the feedback primitives corresponding to the adjacent messages in the whole process may be first statistically analyzed to obtain the processing performance data of the network or the device to be tested in the whole process, and then the time interval between the feedback primitives corresponding to the adjacent messages in the time periods corresponding to different scenes may be statistically analyzed to obtain the processing performance data of the network or the device to be tested in each time period.
For example, the maximum value, the minimum value, and the average value in the time period may be counted according to different time periods (for example, in units of seconds) to obtain the processing time and the processing performance of the network under test or the device under test in different scenarios, where the different scenarios described may be different time periods during which the device under test or the network is in operation, and may also be time periods in different temperature states. Therefore, the processing speed and the processing performance of the tested device or network under the current FC-AE bus pressure are obtained, a test report can be generated based on the processing performance data, and the test report is fed back to the user control end through the communication interface. Therefore, the user control end can acquire the processing performance of the tested equipment or the network under different pressures, and accurate reference is provided for the evaluation of the equipment and the construction of the network.
The embodiment of the invention provides a pressure testing method for an FC-AE bus, which is applied to a programmable logic device, wherein the programmable logic device is in communication connection with a user control end and is connected with a network or equipment to be tested through the FC-AE bus. According to the technical scheme of the embodiment of the invention, the test data is packaged according to the data format of the FC-AE bus, after the message is obtained, the transmission of the message on the FC-AE bus can be controlled according to the flow control information by combining the characteristics of the FC-AE bus, the flow of the FC-AE bus is accurately controlled, and the processing performance data of the tested network or equipment is calculated and obtained based on the time interval between the obtained adjacent message feedback primitives.
