The Design And Implementation Of Port Aggregation Of Ethernet Switch

With the expansion and improvement of internet service, there is an increasing demand for network traffic. Under this trend, requirements on the wideband of the network equipment are becoming higher, and requirements on the network stability and disaster tolerance of the data link are stricter. How to expand bandwidth without increasing equipment and how to control the running cost are the focus of attention of the network operators and industry customers.Based on this current status, this thesis provides a solution for implementing link aggregation, briefly introduces the function of link aggregation, describes the principle and protocol to which the module for realizing link aggregation relates, analyses in detail the design and testability of the module's data structure, studies the switch and synchronization involved in the technology and the processing flow of said module to different types of data packet, puts forward the synchronization mode of using independent events in the module, and designs the data structure, the interface with the external module and the subroutine, so that the link aggregation on the Ethernet switch is realized and passes the test.The technology of link aggregation realized in this thesis not only satisfies the flexible and personalized networking requirements, but also improves the service performance of the equipment. It adheres to the design ideology of"focusing on service and performance with service progressing smoothly"as well as improves the service performance of the switch.
