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.
Referring to fig. 1, a schematic flow chart of a simulation control method for an FC-AE bus according to an embodiment of the present invention is shown, where the method includes:
s101: receiving simulation parameters and scheduling information set by a user, and generating a scheduling table and a preset corresponding relation according to the scheduling information; the scheduling table comprises scheduling strategies, and the preset corresponding relation represents the corresponding relation between the sensitive information and the scheduling strategies.
In this embodiment, the simulation parameter is parameter information required for generating and sending a simulation packet, and includes, for example: simulation mode, rate, simulation time (or simulation times), message length, message type, sequence interval, etc. The scheduling information is information required for generating a scheduling table and a preset correspondence, and includes, for example: scheduling policies, sensitive information and the like, wherein each scheduling policy corresponds to the sensitive information one to one. And the user can set the simulation parameters and the scheduling information according to the actual situation.
After a user needs to set a message type, a simulation mode is set according to the set message type, and if the set message type is a data message, one of three simulation modes corresponding to the data message, namely a fixed data simulation mode, an incremental data simulation mode and a random data simulation mode, is selected to be set as the simulation mode of the simulation. And completing the configuration of other simulation parameters at any time before the simulation starting instruction is sent.
Sensitive information includes some key field information of the FC-AE bus, such as source address, destination address, switch number, message number, etc.
The scheduling strategy is set by a user, the scheduling strategy corresponds to the sensitive information one by one, if the user sets 3 scheduling strategies in primary simulation, the source address of the simulation message corresponding to the first scheduling strategy is 1, the destination address is 2, and the source address of the corresponding sensitive information is 2, the destination address is 1; the source address of the simulation message corresponding to the second scheduling strategy is 2, the destination address is 3, and the source address of the corresponding sensitive information is 3, and the destination address is 2; the source address of the simulation message corresponding to the third scheduling policy is 3, and the destination address is 4, and the source address of the corresponding sensitive information is 4, and the destination address is 3.
In this embodiment, after receiving the simulation parameters and the scheduling information set by the user, the simulation parameters and the scheduling information are latched, that is, the simulation parameters and the scheduling information are stored in the storage medium, so that the information can be conveniently called for use later.
The generation process of the scheduling table and the preset corresponding relation comprises the following steps:
acquiring a scheduling strategy and sensitive information from the scheduling information;
generating the scheduling table according to the acquired scheduling strategy; each scheduling strategy corresponds to a scheduling strategy address;
and corresponding the scheduling policy address with the acquired sensitive information to obtain the preset corresponding relation.
In this embodiment, the scheduling table includes a plurality of addresses, issues the scheduling policy to each address, and represents the address including the scheduling policy as the scheduling policy address. And, the scheduling policy is issued to each address, which may be issued according to a preset sequence, or may be issued randomly to the address.
And the sensitive information corresponds to the scheduling policy one by one, and after the scheduling policy is stored in each address of the scheduling table, the corresponding relation between the scheduling policy address and the sensitive information can be obtained, namely the preset corresponding relation.
For example, the following steps are carried out: assuming that the length of the scheduling table is 10 and the address of the scheduling table is 0-9, issuing the scheduling policy to the address of 0-9, and corresponding the address of the scheduling policy to the sensitive information to obtain a preset corresponding relation.
In this embodiment, simulation parameters such as a simulation mode, a rate, simulation time, simulation times, a message length, a message type, and a sequence interval are set by a user, so that the configuration of the rate of message transmission, the message length, and the like, the control of the simulation time or the simulation times, and the like in the simulation process are realized, and the simulation of the performance of the FC-AE bus is realized in different simulation modes, different rates, and simulation scenes.
S102: and responding to a simulation starting instruction, generating a first simulation message according to the scheduling table, and sending the first simulation message to the FC-AE bus node.
In this embodiment, different scheduling policies are stored in each address of the scheduling table, a simulation message is generated according to the scheduling policy in the scheduling table (in this step, when a simulation start instruction is received, a simulation message, that is, a first simulation message, may be generated directly according to one scheduling policy in the scheduling table), and the first simulation message is sent to the FC-AE bus node, so as to obtain a response message of the FC-AE bus node to the first simulation message. After receiving each simulation message, the FC-AE bus node feeds back a response message.
The scheduling strategy stored in any address in the scheduling table can be called, and the first simulation message is generated according to the scheduling strategy. Specifically, S102 includes:
acquiring a scheduling strategy stored on a preset address in the scheduling table;
generating a first simulation message according to a scheduling strategy stored on a preset address in the scheduling table;
and sending the first simulation message to the FC-AE bus node.
The preset address may be any address in the schedule table, for example, the preset address may be a first address of the schedule table.
In this embodiment, the simulation start instruction may include the following two implementation manners:
the first implementation mode comprises the following steps: the simulation starting instruction is generated through manual starting and responds to the manual starting instruction.
For example, the following steps are carried out: the simulation control system comprises a starting button, and a user can operate the manual starting button or control and respond to the manual starting instruction to generate a simulation starting instruction.
The second embodiment: and starting simulation according to a preset starting trigger signal to generate a simulation starting instruction.
S103: and receiving a response message fed back after the FC-AE bus node receives the simulation message each time.
In this embodiment, after sending the first emulation packet to the FC-AE bus node, the FC-AE bus may generate a response packet according to the first emulation packet, and feed back the response packet to the emulation apparatus.
And before the simulation is not stopped, subsequently, indexing is carried out in the scheduling table according to the sensitive information in each response message and the preset corresponding relation to obtain a corresponding scheduling strategy, and when each scheduling strategy is obtained, a simulation message (namely a second simulation message) is generated according to the scheduling strategy and the simulation parameters, and the generated simulation message is sent to the FC-AE bus node. After the FC-AE bus node receives the simulation message each time, the simulation message received each time is fed back to a corresponding response message of the simulation device, and the simulation is completed by circulating execution. The whole simulation process is illustrated here by way of example: further, the 3 mentioned above scheduling policies are explained, after the simulation start instruction is obtained, if the first scheduling policy is executed, the source address of the sensitive information corresponding to the first scheduling policy is 2, and the destination address is 1, so that the first simulation message with the source address of 1 and the destination address of 2 is generated and sent to the FC-AE bus node. And if the source address of the sensitive information in the feedback response message after the FC-AE bus node receives the first simulation message is 4 and the destination address is 3, correspondingly generating a second simulation message with the source address of 3 and the destination address of 4 by combining the simulation parameters and the third scheduling strategy corresponding to the third scheduling strategy, and sending the second simulation message to the FC-AE bus node. And then, after receiving a second simulation message, the FC-AE bus node feeds back a response message, obtains a corresponding source address, a corresponding destination address and the like according to sensitive information in the response message, further obtains a corresponding scheduling strategy, subsequently regenerates a second simulation message according to the scheduling strategy and the simulation parameters, and the steps are repeated until the simulation times or the simulation time is reached to finish the simulation. The source address and the destination address of the sensitive information in the response message fed back by the FC-AE bus nodes in different cycle periods may be the same or different, for example, the first simulation message finally corresponds to the first scheduling policy, the first second simulation message corresponds to the third scheduling policy, the second simulation message corresponds to the second scheduling policy, and the third second simulation message corresponds to the first scheduling policy.
S104: and extracting sensitive information in the response message.
In this embodiment, the extracted sensitive information may be used to perform the following two operations:
1) the system is used for determining the address of the scheduling policy and further indexing the scheduling policy;
2) the method is used for analyzing sensitive information by a user, and specifically comprises the following steps:
and sending the sensitive information extracted from the response message to a host so that the user can analyze the sensitive information.
S105: and indexing in the scheduling table according to the sensitive information in the response message and the preset corresponding relation to obtain a scheduling strategy corresponding to the sensitive information in the response message.
In this embodiment, the above mentioned generation of the corresponding relationship between the representative scheduling policy address and the sensitive information, where the sensitive information is used to determine the scheduling policy address in the scheduling table, where the sensitive information includes: the step S105 includes indicating information such as a destination address, a source address, and a switching number, where the indicating information is used to index in a scheduling table to obtain a scheduling policy of next simulation, and specifically includes:
acquiring indication information from the sensitive information;
and obtaining a scheduling policy address according to the indication information and a preset corresponding relation, indexing from the scheduling table according to the scheduling policy address, and obtaining a scheduling policy stored in the scheduling address.
In this embodiment, in the received response message, if no sensitive information is extracted, the scheduling policy of the next address in the scheduling table may be obtained. Wherein the next address is for the address of the corresponding schedule at the last simulation.
S106: and generating a second simulation message according to the scheduling strategy obtained by the index and the simulation parameters, and sending the second simulation message to the FC-AE bus node.
In this embodiment, the simulation parameters include a first simulation parameter for determining contents of the simulation sequence and a second simulation parameter representing a message sending manner, and a second simulation message may be generated and sent according to these parameters, specifically, S106 includes:
generating a simulation sequence according to the scheduling strategy obtained by the index and the first simulation parameter; the first simulation parameter is a parameter which represents the simulation sequence content in the simulation parameters;
and generating a second simulation message according to the second simulation parameter and the simulation sequence. The second simulation parameter is a parameter representing a message sending mode in the simulation parameters.
Here, specific explanations are made: the first simulation parameter comprises a message type, a simulation mode, a message length and the like, the message type determines the type of a simulation sequence, such as a data type, a primitive type and the like, the simulation mode determines the expression form of the simulation sequence, such as a fixed data simulation mode, an incremental data simulation mode, a random data simulation mode and the like, the message length determines the length and the division of frames in the simulation sequence, and if the length of data in the simulation sequence exceeds the length of a preset frame of message, the simulation sequence comprises a plurality of frames of messages. In this way, a content-determined simulation sequence can be generated in combination with the scheduling policy and the first simulation parameters. The second simulation parameters comprise speed, simulation time (or simulation times), sequence intervals and the like, the sending mode of the simulation sequence is determined according to the second simulation parameters, a second simulation message meeting the determined sending mode is obtained, and the second simulation message is sent to the FC-AE bus node. Here, taking the sequence interval as an example, when the multi-frame message is included in the emulation sequence, the multi-frame message may be sent in the following manner, including:
after a frame of message is sent, judging whether the current time interval reaches a preset sequence interval or not; wherein, the current time interval is the time from the current time to the last frame of message transmission;
and if the current time interval reaches the preset time interval, sending the next frame message.
And after all the frame messages are sent out, the second simulation message is successfully sent.
It should be noted that, the user can control the simulation time or the number of times of sending messages in the simulation by setting the simulation time or the number of times of simulation in the simulation parameters. Specifically, the method comprises the following steps:
judging whether the preset simulation times or the preset simulation time is reached; the preset simulation times are simulation times set by a user, and the preset simulation time is simulation time set by the user.
And if the preset simulation times or the preset simulation time is reached, stopping the simulation.
