Maybe more relevant is to ask the question, "What do each of these different technologies give us that the others do not?" IPv6, as far as I can see, gives us complete address independence for every device on the planet. I know little of how routing protocols deal with it but inherently, a larger address field doesn't directly lead to better control of routes. GigE gives the local networks higher WAN speeds without switching between protocols, but says nothing of address independence or traffic control. Overall, it give cheaper speed MPLS gives us complete control over routes taken by any particular packet and address independence of a sort at the cost of more edge (and potentially more core) processing. Now look who's buying what, and why. Sprint Canada and Qwest (so I hear form a middle manager friend) will not use MPLS, choosing to throw bandwidth at any congestion problem. For VPNs they are using something other that MPLS. Some other Canadian telcos are specifically using MPLS for VPNs to support a large government project, not mentioning much about the TE aspects but using all the CoS aspects allowed by labeling each packet separately based on source, destination, protocol or port. All in all, not any one of us will get to choose which will "win" and therefore where to put our efforts. Like sharks, we need to keep moving just to stay alive in this field. Expertise in any one of the above will afford a reasonable living but with no guarantees. Stay nimble, or as I say to myself, learn to dance on marbles.
