They are engineering a 16 port x 2.4Gbps per port = 38.4Gbps
Shared backplanes could (at the time of writing) support 20Gbps, not enough.
They present iSLIP, a simple effective router scheduling algorithm.
While iSLIP allows for high throughput (100%) of the router's backplane, it does not address delays which might be problematic for latency sensitive applications. Thus, they introduce the intuitive mechanisms of prioritization and speedup (get all packets to the output port as quickly as possible so they can be scheduled).
- average internet packet is 250 bytes
Keep this paper on the list! It is very informative for those of us who don't know router architecture coming into the course (which I imagine might be a non-trivial portion of us).
