http://www.rdn.ac.uk/ (A British site that links to research sources)

A gateway is a network point that acts as an entrance to another network. On the Internet, a node or stopping point can be either a gateway node or a host (end-point) node. Both the computers of Internet users and the computers that serve pages to users are host nodes. Gateways can transcode or allow different protocols to talk to each other.
