Google Protocol Buffers

This proposal from the High Performance Working Group entails the use of Google Protocol Buffers (GPB) to produce fast and compact encodings of FIX messages.

The use of GPB is one of the three major approaches to the efficient encoding of FIX that have been developed and are being proposed by the High Performance Working Group; the others being the use of FIX-specific binary encoding called Simple Binary Encoding (SBE) and encoding FIX using Abstract Syntax Notation 1 (ASN.1).
