Here are services to run clients, servers and periodic services using the reactor.
This module (dynamically) defines various Service subclasses that let you represent clients and servers in a Service hierarchy.
They are as follows:
TCPServer, TCPClient, UNIXServer, UNIXClient, SSLServer, SSLClient, UDPServer, UDPClient, UNIXDatagramServer, UNIXDatagramClient, MulticastServer
These classes take arbitrary arguments in their constructors and pass them straight on to their respective reactor.listenXXX or reactor.connectXXX calls.
For example, the following service starts a web server on port 8080: 
TCPServer(8080, server.Site(r)).  See the documentation for 
the reactor.listen/connect* methods for more information.
