Abstract

The [IEEE802.15.4] standard specifies an MTU of 127 bytes, yielding about 80 octets of actual Media Access Control (MAC) payload with security enabled, on a wireless link with a link throughput of 250 kbps or less. The 6LoWPAN adaptation format [RFC4944] was specified to carry IPv6 datagrams over such constrained links, taking into account limited bandwidth, memory, or energy resources that are expected in applications such as wireless sensor networks. [RFC4944] defines a Mesh Addressing header to support sub-IP forwarding, a Fragmentation header to support the IPv6 minimum MTU requirement [RFC2460], and stateless header compression for IPv6 datagrams (LOWPAN_HC1 and LOWPAN_HC2) to reduce the relatively large IPv6 and UDP headers down to (in the best case) several bytes.

Abstract

   This document updates RFC 4944, "Transmission of IPv6 Packets over    IEEE 802.15.4 Networks".  This document specifies an IPv6 header    compression format for IPv6 packet delivery in Low Power Wireless    Personal Area Networks (6LoWPANs).  The compression format relies on    shared context to allow compression of arbitrary prefixes.  How the    information is maintained in that shared context is out of scope.    This document specifies compression of multicast addresses and a    framework for compressing next headers.  UDP header compression is    specified within this framework.
