Hundreds of millions of Broadcom-based cable modems at risk of remote hijacking, eggheads fear

Re: DDoS

Question is though, what bandwidth is there upstream from the head ends? Sure, maybe each modem could peak at 1G/s up on a good day, but if you get 1000 modems all doing that I highly doubt there's a working 1T/s connection up from each head end to the next level provider (or even the next hop, often another head end, in the cable plant).

At minimum the NOC should notice and if required throttle all those modems to get the storm under control (first network to get DDoSed in such an attack will be the network operator's, after all...)
