An even more sophisticated scenario could include additional appliances such as Internet phones and other kinds of thin clients . It should be pointed out that all devices would need network access, to the Internet and possibly other IP networks. Sharing of peripherals such as printers, scanners and mass-storage devices will be also required. While a large number of technologies are currently proposed for home networking, this report will focus on Ethernet-based solutions. Moreover, Internet access devices supporting xDSL broadband technology and Ethernet connections to home appliances are already available in the market.
Customer premises network.
At the same time, it is necessary to guarantee that all clients are able to inter-communicate when no remote access connection is established or when the NT is switched off. This means that every device that is connected to the CPN must be provided with its own local IP address, either statically or dynamically assigned, valid only in the context of such a network. The terminal-owned local IP address remains valid inside the CPN and the NT itself acts as an IP gateway. The PPP session is mapped to an individual virtual channel at the NT side. In this case a second IP address, an official one, is assigned to each terminal that sets up a remote connection.
