And obtaining the results of the algorithm such as the overhead of the whole network, the end-to-end delay of the data packet and the like.
Through the embodiment, the terminal 102 can perform the second simulation on the preset network model by using the extended bellman ford algorithm, so that the bandwidth simulation verification based on the flow is performed on the power integrated data network.
In one embodiment, obtaining a bandwidth simulation verification result corresponding to the power integrated data network according to the first simulation result and the second simulation result includes: obtaining a receiving and sending expense simulation result corresponding to the power comprehensive data network according to the first receiving and sending expense and the second receiving and sending expense; obtaining a receiving and dispatching delay simulation result corresponding to the power integrated data network according to the first receiving and dispatching delay and the second receiving and dispatching delay; and obtaining a bandwidth simulation verification result corresponding to the power integrated data network according to the receiving and sending overhead simulation result and the receiving and sending delay simulation result.
In this embodiment, the terminal 102 may obtain a bandwidth simulation verification result corresponding to the power integrated data network based on the first simulation result and the second simulation result. Specifically, the terminal 102 may implement an OSPF-QoSR (quality of service routing) based on a genetic-ant colony fusion algorithm (GAAA) and an extended Bellman-Ford algorithm (EBFA) under the same network Model, compile through each Process module (Process Model), collect statistical parameters, run a simulation, and compare the two algorithms in terms of overhead of the entire network and end-to-end delay of a data packet. After obtaining the first transceiving overhead and the second transceiving overhead, the terminal 102 analyzes and compares the transceiving overhead simulation results formed by the first transceiving overhead and the second transceiving overhead, as shown in fig. 6, where fig. 6 is an interface schematic diagram of the transceiving overhead simulation results in one embodiment. The terminal 102 may collect Global Statistics (Global Statistics) for the whole network, and may also select OSPF → Traffic set (bits/sec) in a preset simulation system to run the simulation. After the simulation is finished, clicking a right button in a working space in a preset simulation system to select Compare Results (comparison result), and comparing the influence of the two algorithms on the whole OSPF network overhead. As shown in fig. 6, curve 402 represents the overhead of the entire OSPF network when using the GAAA routing algorithm, and curve 400 represents the network overhead when using the EBFA algorithm. From the simulation result graph, it can be seen that: (1) the GAAA based OSPF-QoSR is convergent. The simulation is carried out for 0-50 s, the data volume of the route exchange in the whole network is large and the change is rapid; the simulation proceeded approximately 50s later, the data traffic gradually decreased and stabilized, since the OSPF network reached a converged state at this time. (2) The GAAA-based OSPF-QOSR reaches the convergence state earlier (the former starts to converge at about 50s and the latter starts to converge at about 1 min) than the EBFA-based OSPF-QOSR and has less overhead after network convergence.
The terminal 102 may further obtain a corresponding transceiving delay result in the power integrated data network based on the obtained first transceiving delay and the second transceiving delay, and may compare and analyze the transceiving delay result. Specifically, as shown in fig. 7, fig. 7 is an interface schematic diagram of a simulation result of the transceiving delay in one embodiment. The terminal 102 may collect Global Statistics (Global Statistics) for the entire network, select Video configuration → packetnend-to-End Delay (sec), and run the simulation. After the simulation is finished, the operation result including the first transceiving delay and the second transceiving delay may be obtained, for example, the comparreresults command is detected, and the terminal 102 may compare the end-to-end delay of the data packet when the video conference service is supported by the two algorithms. As shown in fig. 7, curve 702 represents the end-to-end delay of a Video conference packet using the GAAA routing algorithm, and curve 700 represents the end-to-end delay of a packet using the EBFA algorithm. From the simulation results, it can be seen that when the GAAA is used for the OSPF-QoSR supporting the Video conference application after the system reaches the steady state, the end-to-end delay of the data packet is smaller than that when the EBFA is used, specifically, the former is about 19ms, and the latter is about 21 ms.
The terminal 102 may obtain a bandwidth simulation verification result corresponding to the electric power integrated data network through the above-mentioned transceiving overhead simulation result and transceiving delay simulation result, so as to perform corresponding configuration on the electric power integrated data network based on the bandwidth simulation verification result.
Through the embodiment, the terminal 102 may compare and analyze the simulation results obtained based on the genetic-ant colony fusion algorithm and the EBFA algorithm, so as to obtain a target algorithm with a small network overhead and a small end-to-end delay of the data packet, and perform configuration based on the target algorithm on the power integrated data network, so as to ensure that the bandwidth is normal in various situations.
