[mpls-linux-general] mpls vs IPv6 (not directly linked to mlps-linux)

[Jung J. <jj...@hs...>]

Hi!

With MPLS I can create MPLS VPNs, QoS can (really?) be
granted to packet flows, and routing is more faster.

IPv6 has the "Flow label" field wich makes routing faster
and has less header overhead than ipv4 (or mpls+ipv4)
And i think flow label could have the same use as
the mpls label value...


My newbie questions are:

How is MPLS to IPv6 related?

Are they technologies that have nothing to do with each other?



Or MPLS can bring new functionalities to IPv6 networks, and so
mpls+ipv6 would have a sense?
And if so, what are the benefits?

Or:

IPv6 has all what mpls+ipv4 has (separeted flows to support qos
VPNs faster routing) and so mpls would have no further use?

In the new IPV6 era what role will mpls play?

thanks for the answers!
and sorry for the bad english
