Abstract

This paper deals with design of FPGA-based flow cache for detecting and maintaining information about heavy-hitter flows.

Annotation

This paper presents an FPGA-friendly approach to tracking elephant flows in network traffic. Our approach, Single Step Segmented Least Recently Used (S3-LRU) policy, is a network traffic-friendly replacement policy for maintaining flow states in a Naive Hash Table (NHT). We demonstrate that our S3-LRU  approach preserves elephant flows: conservatively promoting  potential elephants and evicting lowrate flows in LRU manner.  Our approach keeps flow-state of any elephant since startof-day and provides a significant improvement over filtering approaches  proposed in previous work. Our FPGA-based implementation of  the S3-LRU in combination with an NHT suites well the parallel  access to block memories while capitalising on the retuning of  parameters through dynamic-reprogramming.
