Not trying to be smart or pedantic: modern routers are built out of lots of "ASICs". I imagine the forwarding element design is the differentiator: 1. Fixed pipeline: EARL family 2. Progammable pipeline: UADP family 3. Run-to-completion: "Silicon One" family Not an exhaustive list, lots of other examples etc... -- Tim:> _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
