- 15. | Key Features Overview •IP-based • Simple bridging to other IP networks •Flexible Network • Not tied to specific device types •Robust • No single point of failure •Secure • Robust security, simple commissioning •Low Power devices • Support for battery powered devices Physical Radio (PHY) IEEE 802.15.4 MAC (including MAC security) IPv6 Distance Vector Routing UDP + DTLS Application Layer IEEE 802.15.4 (2006) RFC 4944, RFC 6282, RFC 6775 RFC 1058, RFC 2080 RFC 768, RFC 6347, RFC 4279, RFC 4492, RFC 3315, RFC 5007 Thread Standard 6LowPAN RFC 4862
- 16. | • All devices have IPv6 address plus short address on HAN • Devices for Unique Local Address (ULA) locally or Global Unicast Address (GUA) if IPv6 prefix available • Home Network can directly address devices through Border Routers • Cloud Services can address devices from the Internet • Devices use IP to address any connected node — HAN, LAN, or WAN IP-based: Direct Addressability End Device Thread Leader Thread Router Border Router Thread Link
- 17. | • Devices join as Router Eligible or End Device • Router Eligible: Can become Routers if needed • First router on network becomes Leader • Leader: Makes decisions within network • End Devices: Route through parent • Can be “sleepy” to reduce power consumption Flexible: Simplified Device Types End Device Thread Leader Thread Router Border Router Thread Link
- 18. | • Dynamic Leaders • If Leader fails, another Router will become Leader • Router Promotion • Leader can promote Router Eligible devices to Routers to improve connectivity if required Robust: No Single Point of Failure End Device Thread Leader Thread Router Border Router Thread Link New Leader Promoted to Router
- 19. | • Simple Commissioning • User authorizes devices onto the network using smart phone or web • Can be done on network if there is a device with a graphical interface (GUI) • DTLS Security session established between new device and commissioning device to authenticate and provide credentials • Once commissioning session is done — device attaches to network • MAC security used for all messages • Application level security is based on end-device Secure: Security and Commissioning End Device Thread Leader Thread Router Border Router Thread Link
- 20. | • Sleeping devices poll parents for messages (or remote device if application configured) • Sleeping devices not required to check which allows lower power operation • Parents hold messages for sleeping devices • Sleeping device automatically switches parent connection is lost Low Power Operation: Sleepy Devices End Device Thread Leader Thread Router Border Router Thread Link
- 21. | • Commercial products must be certified in order to receive the Thread logo • Validation of device behavior • Commissioning • Network functionality and interoperability • Device operation in network • The certification program addresses components and end products • Sponsor and Contributor Members have access to a standard test harness and sample commissioning app • Certification uses a 3rd party test lab Thread Certification
- 22. | • Enables users to effortlessly add devices on the Thread Network and manage settings • Designed as a reference app with source code for all Sponsor and Contributor level members • Communication via Thread Group’s MeshCoP Protocol and CoAP • Communication library written in C and C++, leveraging code that is extendable across iOS and Android Thread Commissioning Application
