message-io - Fast and easy-to-use event-driven network library.

•    Rust

message-io is a fast and easy-to-use event-driven network library. The library handles the OS socket internally and offers a simple event message API to the user. It also allows you to make an adapter for your own transport protocol following some rules, delegating the tedious asynchrony and thread management to the library. Managing sockets is hard because you need to fight with threads, concurrency, full duplex, encoding, IO errors that come from the OS (which are really difficult to understand in some situations), etc. If you make use of non-blocking sockets, it adds a new layer of complexity: synchronize the events that come asynchronously from the Operating System.

mcjoin - Simple multicast testing application for UNIX

•    C

mcjoin is a very simple and easy-to-use tool to test IPv4 multicast. Simply start a multicast generator (server) on one end and one or more data sinks (clients). By default the group 225.1.2.3 and the UDP port 1234 is used, you may want to use the MCAST_TEST_NET from RFC5771, 233.252.0.0/24, or the ompoing(8) test group 232.43.211.234, defined in this IETF draft http://tools.ietf.org/html/draft-ietf-mboned-ssmping-08 and UDP port 4321. At the moment max 250 groups can be joined.
