GIN was inspired by tequila from jcfontain but i wanted a distributed system with no dedicated server and faster performance. gin uses udp packets from either Tnm by Juergen Schoenwaelder this is currently broken as Tnm Udp Stuff seems to have been turned inside out. or TclUDP from Pat Thoyts Multicast Adresses are used for sending to multiple addresses. in my application sensors of any kind send their data on a multicast channel. Ackknowledges of commands ( to any actor ) are repeated on a multicast channel. Unicast Adresses for sending to a single instance actor. in my Applikation Actors of any kind get their data from a unicast channel.
