Using the flexibility and low cost of simulation methods in the design of electronic and communication systems, analyzing whether the performance parameters of the designed system meet the design specifications can greatly reduce the risk of adopting new technologies and methods and help to reduce BONeS, the best network protocol simulation tool, is introduced and the BONeS system simulation tool is used to conduct a physical modeling and simulation analysis on a hybrid ATM system with 8 × 8Banyan structure as the core. The quality of service that the system can provide under a certain business load, and get the relationship between the buffer length of the switch and the cell loss rate and the delay of exchange, which is of guiding significance to engineering design.
