This specification provides an architectural framework, called IPv6 Label
Switching Architecture or 6LSA, for an end-to-end, IP-centric packet
switching technique that uses the IPv6 packet header Flow Label, header
extensions, and unique routing algorithms, the latter two when needed, to
establish IPv6-based label switched paths. The label switched paths, called
of packets and as means for quality of service (QoS) solutions as in
IPv4-based MPLS or ATM. Since MPLS-like protocol labeling will be redundant
for IPv6 and since there are no widely-known QoS deployments of IPv6 over
any of the layer 2 switching mechanisms such as ATM, the 6LSA framework
fills the technology void without the link overhead from extraneous layer 2
labeling and signaling of MPLS, or packet fragmentation and added signaling
as in ATM. Through the use of fast switching of 20-bit labels instead of
provides processing savings through significantly reduced address fetches
for the low-powered, handheld devices.
