Stephen -- i simply attached a date after the title. BTW - backplane capacity is not the same as user goodput capacity; and ethernet switch is not the same as a router. Cisco products historically demonstrated that quite clearly. And i'm working for a cisco competitor now (after the acquisition of GeoTel) and have no incentive to promote newer cisco's products :) --vadim Stephen Sprunk <ssprunk@cisco.com> wrote:
Perhaps you could update this paper to reflect current products, since you specifically name vendors and their products' limitations without explicitly listing any model numbers or dates?
For instance, the Cisco GSR (aka 12000) router has a non-blocking backplane capacity of 40Gbit/s, where you list a maximum backplane capacity of 0.7Gbit/s. Also, the Cisco 6500 switch has a non-blocking backplane capacity of 256Gbit/s and can currently hold up to 130 GigE ports. This shows two orders of magnitude growth in capacity since your paper was written, and that's not counting the products I can't tell you about yet :)
While I understand that the actual numbers are mostly irrelevant to the paper, it would be appreciated if you'd either update the numbers or put in a footnote recognizing that your numbers are out of date.
