Deployment of the Low Weight IETF protocols In Internet of Things(IOT)
draft-fu-lwig-iot-usecase-00
This draft analyze the development and deployment of the existing IETF Low weight IPv6 protocols in the IOT (Internet Of Things) industry. Taking consideration on the constrained resource nature of devices, the IETF low weight IPv6 protocols, including 6LowPan, RPC and COAP, fit perfectly in the IOT scenarios. Recent development and promotion of Zigbee IP and IPSO also extend the use of these low weight IPv6 protocols.

With the fast development of wireless sensor technology and IC technology, the concept of IOT (Internet Of Things) has been realized and promoted in the Information Industry. IOT intends to build a network to connect all devices, systems and services, which claims a vast need of IP addresses.Due to its inherent advantage of huge address pool, IPv6 has been chosen as the fundamental Internet protocol by IETF ever since the research of IOT.
Due to the constrained resource nature of devices in IOT, working groups in IETF mainly focus on low weight IPv6 protocols, which include 6LowPan working group, RoLL working group, and CoRE working group. Other standardization organizations, such as IPSO, Zigbee, ISA and etc., are dedicated in promoting the deployment of these protocols. With years of research and development, a number of application cases and solutions for IOT based on IPv6 have been proposed and deployed. In this draft, we will summarize the latest deployments and usecases of protocols about IPv6 in IETF.

ZigBee is the industry alliance based on IEEE 802.15.4. It mainly focuses on standarization of network laryer and application layer in short range wireless communication.The PHY and MAC layer of ZigBee is IEEE 802.15.4.
ZigBee IP is the first open standard for an IPv6-based full wireless mesh networking solution and provides seamless Internet connections to control low-power, low-cost devices. It connects dozens of the different devices into a single control network.
ZigBee IP was designed to support the ZigBee Smart Energy version 2 standard, published in 2013, which offers a global standard for IP-based control,both wired and wireless, for energy management in Home Area Networks(HANs).Such standard is expected to be used in Smart Grid applications.
Zigbee IP has been recently updated to include 920IP, published in July, 2014,which provides specific support for ECHONET Lite and the requirements of Japanese Home Energy Management systems. 920IP was developed in response to Japan's Ministry of Internal Affairs and Communications (MIC) designation of 920 MHz for use in HEMS and Ministry of Economy, Trade, and Industry(METI) endorsement of ECHONET Lite as a smart home standard. 920IP is the only standard referenced by the Telecommunications Technology Committee (TTC) which supports multi-hop mesh networking.
The ZigBee IP specification enriches the IEEE 802.15.4 standard by adding network and security layers and an application framework. ZigBee IP offers a scalable architecture with end-to-end IPv6 networking, laying the foundation for an Internet of Things without the need for intermediate gateways. It offers cost-effective and energy-efficient wireless mesh network based on standard Internet protocols, such as 6LoWPAN, IPv6, PANA, RPL, TCP, TLS and UDP. It also features proven, end-to-end security using TLS1.2 protocol, link layer frame security based on AES-128-CCM algorithm and support for public key infrastructure using standard X.509 v3 certificates and ECC-256 cipher suite. ZigBee IP enables low-power devices to participate natively with other IPv6-enabled Ethernet, Wi-Fi and, HomePlug devices.
ZigBee IP has been paid great attention once it was published in 2013. Several chip companies, including Exegin, Silicon Labs, TI and etc., have developed chips that support ZigBee IP.
The IPSO Alliance performs interoperability tests, documents the use of new IP-based technologies, conducts marketing activities and serves as an information repository for users seeking to understand the role of IP in networks of physical objects. Its role complements the work of entities such as the Internet Engineering Task Force (IETF), Institute of Electrical and Electronics Engineers (IEEE) or the ISA which develop and ratify technical standards in the Internet community.
The ultimate goal of IPSO is to promote the use of IP in the IOT. Considering the constraint nature of the IOT devices, several technologies, including Lightweight OS, 6LowPan, COAP, and RPL, are promoted in IPSO. Members of IPSO have developed large number of commercial devices that support IP-communication. For example, Toshiba has developed a IPv6-capable TV. Axis provides IPv6-capable camera for surveillance use.
The broad IOT market brings opportunities for operators world wide. Interesting deployments of IOT or M2M (Machine to Machine) cases based on IPv6 have emerged over the years.For example, the French Telecom deploys IPv6 based M2M network in Smart Metering, Intelegent Health Monitering, and Smart City. Considering the constraint nature of the devices, low weight IPv6 protocols, including 6LowPan, RPL, and COAP are utilized.
This draft introduces the recent development and deployments of low weight IPv6 protocols studied in IETF. Taking careful consideration on the constrained resource nature of the devices in IOT, these low weight IPv6 protocols,including 6LowPan, RPL, and COAP, are proved to be quite a success in the IOT scenarios. Generation and improvements of industrial standards, such as Zigbee IP, also accelerate the deployment of the low weight IPv6 protocols. We can predice that IOT might be a "killer scenario" of the extensive deployment of IPv6 world wide in the near future.
