The following elements must be taken into account in the network architecture,

as illustrated in Figure 11.13:

•

Place and configuration of the various PLC gateways and PLC signal injection;

•

Hotel Internet access;

•

Network keys of the various PLC networks, whether separated or not;

•

Network links between the buildings.

Figure 11.14 illustrates the overall logical architecture to be implemented. It

includes wired Ethernet sections, like the link between the two buildings, since we

want to maintain good performance in terms of throughput and a guaranteed ser-

vice in order to avoid degrading the IP service in building B.

In order to separate the various PLC networks, it is important to place them on

different phases if this is possible (three-phase cables and a neutral cable in the case

of a three-phase installation) and especially to configure different network keys for

each desired service. In terms of security, the installation of a RADIUS server can be

envisaged in order to authenticate the PLC network clients.

This Figureure shows the connections of the PLC networks to the information

system, especially the Internet accesses in the hotel bedrooms and the configurations

with a NAT router for the meeting rooms used for protecting the customers’ PCs

and also the corporate network with respect to the administered PLC networks.
