Does not look like it [1]. It appears to be a protocol that enumerates your exact path, interface by interface, on every data packet. So you can just blindly forward to the next hop written in the packet itself.

By my guess, a competent and efficient implementation should be able to run the routing logic at ~30-100 million packets per second per core. That would be ~300-1,000 Gb/s per core, so you would bottleneck on your memory bandwidth if you have even a single copy.

Is this some MPLS-like thing?

Don't forget checking the MACs.
