Commissioning in 6LoWPAN

This document by Ki-Hyung Kim and S. Daniel Park from .IETF70 covers the initial steps taken by 6LoWPAN devices when they start operations. It delves into joining existing networks, obtaining IP settings, and more. The Bootstrapping Procedure and steps involved are explained in detail, focusing on IPv6 address acquisition and network association. Feedback on the draft is encouraged for consideration as an official WG item.

  1. 6LoWPAN WG, IETF70, Vancouver Commissioning in 6LoWPAN Ki-Hyung Kim (picosNet Corp/Ajou University) and S. Daniel Park (SAMSUNG Electronics)

  2. 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. 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. 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 aunique IPv6 address, • and constructing security credentials for 6LoWPAN

  5. 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. 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. Next Steps • Feedback is welcome • Any comments/suggestions? • Is the WG interested in this draft as a WG item?
