+ dae, means goose, is a lightweight and high-performance transparent
+ proxy solution.
+
+ In order to improve the traffic diversion performance as much as possible,
+ dae runs the transparent proxy and traffic diversion suite in the linux
+ kernel by eBPF. Therefore, we have the opportunity to make the direct
+ traffic bypass the forwarding by proxy application and achieve true direct
+ traffic through. Under such a magic trick, there is almost no performance
+ loss and additional resource consumption for direct traffic.
