Background: In order to solve the safety hazard of computer network security, a special
congestion control strategy is adopted.
Methods: This strategy is used to discuss the design and implementation technology of a network
adapter, a bridge, concentrator, a device driver, Netware interface software, and a complete set of
FDDI optical fiber computer networks. The following functions i.e. source address tracking, frame
forwarding, frame format conversion, spanning tree protocol, and other functions were achieved.
Results: The research shows that the Sunrays micro-computer follows the SNMP simple network
management protocol, which can support multiple Ethernet protocols and multiple ports, and the
number of ports is scalable.
Conclusion: The proposed method is useful for the multiple input and output ports in a computer
network with security enabled congestion control for data traffic.
