Commissioning in 6LoWPAN Ki-Hyung Kim (picosNet Corp/Ajou University) and S. Daniel Park (SAMSUNG Electronics) 6LoWPAN WG, IETF70, Vancouver

2 IETF70 Van Couver5 Dec 2007 The Goal of the Commissioning  Defines the procedure taken by 6LoWPAN devices when they first start operation.  Involves starting a new network, becoming part of existing network and obtaining IP settings.

3 IETF70 Van Couver5 Dec 2007 Terminology  Active Scan  Association  Coordinator  ED Scan  Full Function Device (FFD)  Neighbor Table  PAN Id  Passive Scan  Personal Operating Space (POS)  Reduced Function Device (RFD)  Short Address

4 IETF70 Van Couver5 Dec 2007 Bootstrapping  Associating with the network and obtaining IPv6 address.  Specifically, it includes the process of  starting the network,  associating with other nodes,  orphaning a previous network  obtaining a unique IPv6 address,  and constructing security credentials for 6LoWPAN

5 IETF70 Van Couver5 Dec 2007 Bootstrapping Procedure  Consists of the following steps  Orphaning a previous network  Scanning through channels  Starting a new network  Joining the network with association  Joining the network without association  Setting the beacon data structure  Assigning the short address  Obtaining IPv6 address

6 IETF70 Van Couver5 Dec 2007 Obtaining IPv6 address  IPv6 Address  Interface identifier  EUI-64 identifier  16 bit pan ID + 16 bit short address  Duplicated Address Detection  Send ICMPv6 Neighbor Solicitation  Wait for NA_WAIT_TIME  Network Prefix  IPv6 routers stored the network prefix  ICMPv6 Router Advertisement

7 IETF70 Van Couver5 Dec 2007 Next Steps  Feedback is welcome  Any comments/suggestions?  Is the WG interested in this draft as a WG item?
