Technical Field

[0001] The present disclosure relates to the field of computer communication technology, and in particular to a method for generating FC network simulation data based on a whole network planning file. Background Art

[0002] Network simulation uses mathematical modeling and statistical analysis to simulate network behavior. By building statistical models of network devices and links, network traffic transmission is simulated to obtain network performance data required for network design and optimization, achieving the goal of conducting network performance analysis before the actual object. The simulation of simulation data is the data source of network simulation, and the accuracy of network simulation depends on the accuracy of simulation data.

[0003] FC (Fiber Channel) network is a star-shaped network with FC network switch as the center. FC network switch (hereinafter referred to as switch) and FC network node machine (hereinafter referred to as node machine) are connected by optical fiber. Data is sent and forwarded in sequence according to the priority of data, providing high bandwidth and low latency performance of FC network data communication at a transmission rate of 1Gpbs, 2Gpbs or higher. Data traffic in FC network includes periodic messages, event messages and stream messages.

[0004] As the functions of modern avionics systems continue to expand, the scale of systems increases dramatically, and the interconnection of equipment becomes increasingly complex, the importance of FC network simulation before the actual object becomes more and more prominent. To ensure the accuracy of FC network simulation, it is necessary to establish FC network simulation data that is highly close to the actual network traffic. The traditional way of manually constructing a large amount of network simulation data is labor-intensive and prone to errors. Summary of the invention

[0005] In view of this, the embodiment of the present disclosure provides a method for generating FC network simulation data based on the whole network planning file, which is based on the FC network whole network planning configuration file (hereinafter referred to as the FC network planning file), establishes a FC network message list by performing the correctness check, information stripping and extraction of the whole network planning file, and performs traffic simulation according to the simulation parameters and the data characteristics of different message types, generates FC network whole network simulation data, and provides data support for FC network system simulation. The method ensures the accuracy of FC network simulation data, improves the authenticity of simulation data, reduces the complexity of creating simulation data, and greatly improves the efficiency of network system simulation.

[0037] like Figure 1-Figure 2 As shown, the embodiment of the present disclosure provides an implementation method of a method for generating FC network simulation data based on a whole network planning file, which specifically includes the following steps:

[0038] In the first step, the present invention supports external import of FC network planning files in XML (Extensible Markup Language) format. The FC network planning file includes the configuration information of all node machines, sending and receiving communication ports of the FC network, and an error is reported if the information is incomplete. The specific definition is shown in Table 1:

[0039] Table 1 Definition of FC network planning file in XML format

[0040]

[0041]

[0042] In the second step, in order to ensure the parameter correctness and information integrity of the externally imported FC network planning file, the present invention needs to perform a correctness check on the FC network planning file. The steps are as follows:

[0043] (1) Verify the integrity of each field in the FC network planning file and report an error if any parameter is missing;

[0044] (2) Perform a range-limited check on each field parameter in the FC network planning file, report any error information, and indicate the cause of the error;

[0045] (3) Check the global uniqueness of the node machine number and the sending communication port number in the FC network planning file, as well as the uniqueness of the receiving communication port number under the node machine. If they are not unique, an error message will be reported and the cause of the error will be prompted.

[0046] The third step is to strip and extract the information of the sending communication port attributes of all node machines in the FC network planning file, and establish an FC network message list, as shown in Table 2. The list includes the communication source device, communication identification number, communication direction and communication attributes.

[0047] Table 2 FC network message list

[0048]

[0049]

[0050] The fourth step is to generate FC network simulation data that is close to the real one. It is necessary to define the total number and occurrence time of simulation messages in the FC network. This method uses external input simulation parameters to determine the total number and occurrence time of periodic messages, event messages, and flow messages. The total simulation time T sim( minutes), the maximum number of times event and stream messages are sent per minute SC max (Send Count, number of times sent), as shown in Table 3:

[0051] Table 3 FC network simulation parameter definitions

[0052] Serial number Simulation parameters abbreviation 1 Total simulation time (minutes) Tsim 2 Maximum number of events and stream messages sent per minute SCmax

[0053] The fifth step is to classify the data of different message types in the FC network message list, and select different network simulation data generation methods according to the message type. The steps are as follows:

[0054] (1) The message type is an event message or a stream message. Assume that the sequence number of the message is i, and the maximum number of occurrences per minute is SC max ], a random algorithm is used to generate the number of occurrences of this message per minute C i . Calculate the total number of messages M that occur during the simulation time. i =T si *C i . And use random algorithm to generate the occurrence time T of simulation data i ;

[0055] (2) If the message type is a periodic message, the occurrence time of the first message is calculated using a random algorithm of [0, sending period]. With the sending period as the frequency, the occurrence time T of the Kth message is calculated using a uniform distribution algorithm. iK =T i1 +Sending cycle*(K-1).

[0056] The method for generating FC network simulation data is detailed in Table 4 below:

[0057] Table 4 FC network simulation data generation method

[0058]

[0059] Step 6: traverse all nodes, generate all simulation message sequences of all nodes in the FC network, and sort them according to the priority of the messages in the FC network planning file. Specifically:

[0060] (1) Generate event message, stream message and queue message simulation data of the first node machine;

[0061] (2) Time sorting of all simulation messages of the first node machine;

[0062] (3) Perform a sending conflict check on the simulation message sequence of the first node machine. If multiple simulation data are sent at the same time, sort the multiple simulation data in descending order of priority values.

[0063] The simulation message sequence is specifically defined as shown in Table 5:

[0064] Table 5 FC network simulation message sequence definition

[0065]

[0066]
