The efficiency of buffer management constrains the store-and-forward speed of network switch chip seriously
how to select the suitable cache management methods become the key.This paper puts forward the Linked Storage and Circular Linked Storage management algorithm.They all realized using the linked list.The test and analysis on ALTERAs FPGA development board demonstrate that Linked Storage algorithm saves resource and Circular Linked Storage algorithm brings higher work rate
the two algorithms all can be widely applied to the design of network switch chip.
