Total traffic, 10,000 proxy nodes, 60-s notification interval. The figure shows the total amount of application protocol traffic exchanged in the system during the measurement period when using 10,000 Proxy Nodes (PNs), 1-100 Local Nodes (LNs) per PN, and a 60s CoAP notification interval. A subset of the PNs was assumed to be located behind P2P-unfriendly NATs.
