Abstract
Rapidly growing speed and complexity of computer networks impose new requirements on fast lookup structures which are utilized in many networking applications (SDN, firewalls, NATs, etc.). We propose a novel lookup concept based on the well-known cuckoo hashing, which can achieve good memory utilization, supplemented by a binary search tree for offloading the colliding keys and supporting LPM lookup. We also propose a hardware architecture implementing this lookup concept in the FPGA. Our solution is suitable for lookup of the variable-length keys in 100+Gbps networks. Memory utilization of the proposed concept is thoroughly evaluated and it is shown that the concept is scalable to external memory components.
