Design of advanced metering infrastructure
in smart grid with DAN
Figure II.1 shows the design of AMI with DAN. The architectural components of DAN, such as naming, routing,
caching and forwarding (right-hand side), can correspond with the transport and network layer protocols
[e.g., transmission control protocol/transport layer security (TCP/TLS) and IPv6] in the current protocol stack
of AMI (left-hand side).

Figure II.2 shows how much bandwidth is consumed when the same size content is transferred in AMI based
on DAN (DAN-AMI) and IP (IP-AMI) networks, respectively. In the simulation, 240 smart metres were pushing
data objects to DAN-AMI as well as IP-AMI, and subscribers retrieved the data objects from the network. Due
to the in-network cache and processing functions of DAN elements, requests from subscribers were directly
served by the individual DAN elements holding the data objects and so the network bandwidth consumption
in DAN was significantly reduced compared to IP. The simulation was carried out by using the NDN simulator
[b-ndnSIM].
