As I remember, it used commercial gated.

Getting to 1mpps on a single router today will probably be hard.
However,
I've been considering implementing a "clustered router" architecture,
should scale pps more or less linearly based on number of "PCs" or
"routing nodes" involved. I'm not sure if discussion of that is
on-topic
here, so maybe better to take it offline.

This is exactly what Pluris PC-based proof-of-concept prototype did in
97.
PCs were single-board 133MHz P-IIs, running custom forwarding code on
bare
metal, yielding about 120kpps per board, or 1.9Mpps per cage.

In the production box CPU-based forwarding was replaced with ASICs,
1Gbps
hybrid optical/electrical butterfly/hypercube interconnect was replaced
with 12Gbps optical hypercube interconnect, otherwise architecture was
unchanged.  That was a total overkill which was one of the reasons the
company went down.

 I used to work with an Ascend GRF (goes real fast) Router that was
nothing
more than a hacked BSD os running on a hard drive at first then they moved
to a
flash card that controlled some custom switching hardware. But all the
functions were via the BSD os and I think it just used Gated.

 Sounds very similiar.
