I need to create a network server in C++ for a trading application. This network server needs to perform the following tasks:

  • handle authentication of clients and provide session id for each
    session.

  • handle orders originating from the clients and inform clients about
    their execution.

  • handle other data request asked for by the clients and send data back
    to them.

I am planning to use Boost.Asio networking library and Google protocol buffers to implement the messages being sent from the clients to the server. XML-RPC or SOAP based approaches are a strict no-no as latency is a big concern.

I have the following questions for the stackoverflow community:

  1. Is it a good idea to implement these messages using protocol
    buffers? I am also considering sending messages Boost serialization
    library to implement this. When I look at the code, I find myself
    more confident of implementing this with boost serialization and
    Google protobuf headers look too heavyweight. Which of these methods
    will be a) more maintainable and b) require less effort? I guess,
    both these approaches will work across different platforms.

  2. Is there any other networking library which I should look at apart
    from Boost.Asio.?I find ACE a little dated as far as C++ coding
    style is concerned.

  3. Eventually I would like to make this network server run on SSL,
    however, I do not have any experience with implementing SSL. How
    much effort would it require to move to SSL later on. Should I start
    with SSL or can it be added later on?

  4. Does anybody know of a good open source network project, which might
    have implemented a similar network server using Boost.Asio, to get
    inspired from?

    You should also look at Apache Thrift (originated at Facebook) or Apache Etch (initially developed by Cisco). They are RPC frameworks that make it easy to develop both servers and clients meeting your needs (more or less). For a framework developed using protobuf and boost.asio, look at the server1 project.
