Hi all,****

I‘m currently looking at redesigning an application and changing to boost/c++11 library components.

The application reads data from an input, processes the data and then send it to an output.****

The current architecture is one thread per “device” where a device is a pair of input/output ports and one processing stage.****

What I’d like to do is move this to either a publish/subscribe model or some form of message-based system where an input comes in and a message is then sent to the next stage of the process.****

All stages will happen on the same physical/virtual machine. ****

Are there any good pub/subscribe or message-based components using the boost architecture that works on mac osx/win32.****

We're looking into something around infrastructure as well for a producer/consumer data generator, as well as event brokering type architecture. I wouldn't artificially constrain yourself to boost-based alone. Although we're using boost, several have come to mind: looks like ZeroMQ is a strong horse in that race. Crossroads I/O (XS) popped up as a plausible fork in the ZeroMQ road, but I am discovering it seems to be a dead thing. XS' would-be successor Nanomsg is a work in progress: would ignore it until it's released. Which leaves ZMQ. There may be others, like ZeroC Ice (lighter weight successor to CORBA-esque RPC), but that might be overkill for what you need. For us anyway ecosystem is a concern, so cross platform cross language is a key element as well. Although any of these work just fine in one address space (intra-process), as well as inter-process, and between systems, etc. HTH

Any help appreciated.****
