draft-fu-lwig-iot-usecase-00
Abstract
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.

1. Introduction
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.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. ZigBee IP
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.
4. IPSO
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
Fu Expires April 22, 2015 [Page 3]
Internet-Draft IOT-USECASE October 2014
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.
5. Usecases for Operators
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.
6. Conclusion
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.
