MeowRouter

Routing for cats

MeowRouter is a hardware accelerated IP packet forwarder running on programmable ICs. MeowRouter utilizes the Cuckoo hashing algorithm, and supports external memory accesses through AXI interface, so it is capable of handling large amount of network traffic / pps with huge routing tables.

This repository contains the RTL source code for the data plane, and is intended to be used alongside an CPU. See MeowRouter-top for an example.
