Eli Bendersky: Length-prefix framing for protocol buffers | prg | Scoop.it

I personally find Google’s protocol buffers library (protobuf) extremely convenient for efficient serialization and de-serialization of structured data from multiple programming languages. protobufs are perfect for TCP/IP links in general and socket-based IPC in particular.

Framing (the method of dividing a long stream of bytes into discrete messages) isn’t immediately obvious with protobuf. What you get from a protobuf serialization is a binary buffer of data. You almost certainly want to send more than one such buffer over time, so how does your peer know when one message ends and another starts?
