The evolution of the packet switched ICT technologies is strongly affected by the actual demand of the users. Systems like Internet of Things (IoT), R&D&I instruments with intensive communication, Radio Frequency Identification (RFID) devices, Ubiquitous Sensor Networks (USN), Machine-to-Machine (M2M) communication technologies involve challenges not only for classical data networks, but for converged and Next Generation Networks (NGN), as well. These systems conceive requirements on the common IPv4/IPv6 networks by the transmission demand of Big Data sets simultaneously with the time sensitive traffics guaranteed by Quality of Service (QoS) criteria. The priority mapping to the Virtual Local Area Network (VLAN) with DiffServ and/or IntServ based QoS technics is a common solution for converged IP networks. The Mobile Sensor Networks (MSN) produced by the IoT requires efficient communication standards with low energy consumption.
In our presentation we reflect on the effects of the IoT new communication technologies concerning provision of the converged LAN/MAN/WAN systems and on the technology changes in the OSI model. We analyse technical aspects of the new IoT technologies like Constrained Application Protocol (CoAP), IP Smart Object Network (CoAP), Routing Protocol for Low-Power and Lossy Networks (RPL), IPv6 over Low power wireless Personal Area Networks (6LowPAN), IEEE 802.15.4 - Low-Rate Wireless Personal Area Network (LR-WPAN).
