Efficient connection management solution in high-speed networks

Poor data locality in high-speed networks leads to more memory accesses of connection management, which limits the throughput performance. In view of the above problem, this paper analyzed the process of connection management and access in detail, and put forward the efficient connection management solution to improve throughput on FPGA platform. This solution takes full advantage of the structural characteristics of SDRAM. By controlling access requests, it can make adjacent access requests access different banks, which can reduce hardware resource conflicts, shorten the time interval between access requests and improve throughput. In order to reduce the complexity of control, we selected multiple slots hash table as the data structure for connection management. Simulation results show that this solution shorten the time interval by about 71.4%.
