27 Thread Technical Overview 27

28 Connected Home Technical Requirements Direct addressability device-to-device, device-to-application, device-to-cloud Battery operated devices with years of life door locks, security sensors etc. Simple network joining Intuitive no mysterious button sequences or jargon Scalable to devices per network Latency less than 100 milliseconds for typical interactions Multiple border routers Seamless connectivity to user interaction devices phone, tablet, wall controller 28

29 System Messaging Model Internet WAN Home Router Wi-Fi Thread Border Router Thread mesh Home router Border Router Thread-enabled Devices Routes Thread traffic to/from LAN (Wi-Fi and Ethernet) Routes Thread traffic to/from WAN to enable Mobile device access anywhere Cloud services Border Router forwards data to big home network, typically Wi-Fi or Ethernet Device-to-device communication 29

30 Thread Standards 30 Collection of existing IEEE and IETF standards Uses existing based radios Support for low power, sleepy devices Simple security, user-friendly commissioning 250+ devices No single point of failure Direct device addressability Point-to-point device connectivity Low cost bridging to other IP networks Application Layer UDP + DTLS Distance Vector Routing 6LowPAN (IPv6) IEEE MAC (including MAC security) IEEE PHY Standard RFC 768, RFC 6347, RFC 4492, RFC 3315, RFC 5007 Based on RFC 2080 RFC 4944, RFC 4862 IEEE (2006) IEEE (2006)

31 Thread Network Architecture Thread Node Types End Device Thread Router Leader Border Router Thread Link End Devices may be Router Capable Router Capable devices may be Routers A Router may be elected Leader Border Routers have both Thread and LAN (or WAN) connectivity 31

32 Direct Device Addressability All Thread nodes have IPv6 addresses (6LoWPAN) CoAP messages assign Router addresses (TMF Thread Management Framework) Devices on LAN can directly address Thread nodes through Border Routers Mobile devices can address Thread nodes via LAN or Internet End Device Thread Router Leader Border Router Thread Link Cloud Services can address Thread nodes from the Internet 32

33 Network Topology New nodes initially join network as End Devices Router Eligible End Devices can become routers based on the number of existing routers Routers maintain state to all other Routers through trickle mechanism and MLE advertisements All Routers maintain state of Border Routers through trickle mechanism and MLE advertisements End Devices route through parent Router Leader is a Router that controls and propagates state of network to all other nodes End Device Thread Router Leader Border Router Thread Link 33

34 No Single Point of Failure Leader controls and propagates state of network. If it fails, another Router will become Leader. Adding more Router Eligible nodes may improve connectivity. Thread automatically maintains an optimal number of Routers. Multiple border routers can be used Thread nodes can operate without Border Router End Device Thread Router Leader Border Router Thread Link 34

35 Security and Commissioning Adding new nodes on the network is easy and secure User authorizes new nodes using a smart phone, tablet, or other networked device Security session is established between new node and commissioning device to authenticate the new node and to securely provide credentials Once commissioning session is done, new node attaches to network Once attached, MAC security used for all messages Application-level security may be used in addition to MAC security based on application requirements End Device Thread Router Leader Border Router Thread Link 35

36 Low Power (Sleepy) Nodes Parents hold messages for sleeping nodes zzzz zzzz zzzz When sleeping nodes wake up they poll parents for messages Sleeping nodes are not required to check in on a regular schedule A sleeping node automatically switches parent if it loses connectivity End Device Thread Router Leader Border Router Thread Link 36

37 Certification Thread devices must be certified in order to receive the logo First wave of product testing is currently underway Testing validates device behavior Commissioning Network functionality and interoperability Device operation in network Members have access to the standard Thread test harness and sample commissioning app CONNECTS WITH THREAD 37 Certification uses a 3rd party test lab
