This project provides an java implementation for Google's Protocol Buffer RPC services. The implementation builds upon Netty for low-level NIO.

• TCP connection keep-alive.
• Bi-directional RPC calls from client to server and server to client.
• SSL socket layer encryption option.
• Data Compression option.
• RPC call cancellation.
• RPC call timeout.
• Out-of-Band RPC server replies to client.
• Non RPC Protocol Buffer messaging for peer to peer communication.
• Protocol Buffer wire protocol.
• Semantics for calls handling on TCP connection closure.
• Pluggable logging facility.
