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.
