           IPv6 Mesh over BLUETOOTH(R) Low Energy using IPSP
                       draft-ietf-6lo-blemesh-04

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
   the mechanisms needed to enable IPv6 over mesh networks composed of
   Bluetooth low energy links established by using the Bluetooth
   Internet Protocol Support Profile.

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
   7668, respectively.  Bluetooth 4.0 only supports Bluetooth LE
   networks that follow the star topology.  In consequence, RFC 7668 was
