A common question that comes up is "How can I communicate with olad using something other than C++, Python or Java?".
 
  
== Intro ==
 
  
OLA is a client / server architecture. The clients and the server (olad) communicate over a TCP socket. By default olad listens on localhost:9010.  Data passed between the client and the server is serialized using [https://developers.google.com/protocol-buffers/ Protocol Buffers]. The [https://developers.google.com/protocol-buffers/docs/overview overview] and [https://developers.google.com/protocol-buffers/docs/encoding data encoding] pages describe the specifics of the serialization process.

To write a new client at the very least you need an implementation of protocol buffers for your language. Luckily there is widespread support for protocol buffers in [https://code.google.com/p/protobuf/wiki/ThirdPartyAddOns many languages].
