           IPv6 Mesh over BLUETOOTH(R) Low Energy using IPSP
                       draft-ietf-6lo-blemesh-05

Abstract

   RFC 7668 describes the adaptation of 6LoWPAN techniques to enable
   IPv6 over Bluetooth low energy networks that follow the star
   topology.  However, recent Bluetooth specifications allow the
   formation of extended topologies as well.  This document specifies
   mechanisms that are needed to enable IPv6 mesh over Bluetooth Low
   Energy links established by using the Bluetooth Internet Protocol
   Support Profile.  This document does not specify the routing protocol
   to be used in an IPv6 mesh over Bluetooth LE links.

1.  Introduction

   Bluetooth Low Energy (hereinafter, Bluetooth LE) was first introduced
   in the Bluetooth 4.0 specification.  Bluetooth LE (which has been
   marketed as Bluetooth Smart) is a low-power wireless technology
   designed for short-range control and monitoring applications.
   Bluetooth LE is currently implemented in a wide range of consumer
   electronics devices, such as smartphones and wearable devices.  Given
   the high potential of this technology for the Internet of Things, the
   Bluetooth Special Interest Group (Bluetooth SIG) and the IETF have
   produced specifications in order to enable IPv6 over Bluetooth LE,
   such as the Internet Protocol Support Profile (IPSP) [IPSP], and RFC
