[Boost-users] [ASIO]: Best solution for Publisher/Subscriber pattern

Hi All,

 

currently we do some research in how we can do implement the classical
Publisher/Subscriber pattern using ASIO. We had one thread that produces
some kind of a message and like to send it out to 1 to n subscribers via
TCP, where n is < 5. Message rate will be up to 800 Hz. My first idea is
that the producer thread puts the message in a blocking queue. On the other
end a consumer thread waits, takes the message and send it to the
subscribers via synchronous or asynchronous send. One requirement is, when
one connection blocks (because their client is buggy/hangs) it's ok to drop
messages for that connection, but we should deliver to the other
subscribers. It's also a one way communication from publisher to subscriber.

 

Can someone provide some hints for best practices / design patterns /
comments please?

 

If I show up with some other lib like ZeroMQ my colleagues will fry me, so
it's the easiest to use boost also for that task..

 

Best,

 

Ingo
