IPv6 Mesh over BLUETOOTH(R) Low Energy using IPSP
draft-ietf-6lo-blemesh-02
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
specifically developed and optimized for that type of network
