"I think it would be far easier if WAN protocols were plain GBit Ethernet."
WAN won't be 1GbE, but it will probably be 10GbE with SONET framing, or else OC-192c POS (ie, PPP-encapsulated HDLC-framed MPLS). In either case, I suspect it will be far cheaper in the long run to monitor a big fat pipe than to try to break out a zillion lil' tiny DS1s.

There are dedicated network processors, though, and one can outsorce the filter bottlenecks into an FPGA board. This is still reasonably small and cheap.

I think it would be far easier if WAN protocols were plain GBit Ethernet.
