I have some data that I need to share between multiple services on multiple machines.

UDP socket network disconnect behavior on Windows-Linux-Mac
Hi folks, I made an application using boost.Asio using UDP multicast. I don't think the question is really specific to boost.Asio but to sockets programming in general, since boost.Asio's network facilities are mostly wrappers to socket functions. I constructed the application based on the multicast examples ( http://www.boost.org/doc/...

Multiple simultaneous tcp client connections for performace test
Hi i need to create multiple TCP connections simultaneously to some custom TCP-server application for its performance testing. I know a lot of such for Web (i.e. curl-loader based on libcurl), but I didn't found some general one.
