Hammer 

A real-time RTSP reverse proxy accelerated by GPU.

Composition: 1 dispatcher + 1 GPU worker thread + several CPU worker threads

dispatcher : dispatching connections to CPU workers
CPU worker : batch the data, AES decryption, RSA, forwarding, I/O related operation
GPU worker : HMAC + AES encryption only, process with GPU
