Re: The Article - in readable format said by karlmarx:So, even with Docsis 3, why are they promising 5mb/subscriber per 300 people, when they only have 120MB total? Outside of testing with Spirent, Smartbits, Ixia, or similar there is no real-world IP network scenario where all ports of attachment are maxed out.
The only time we've ever seen anything close to that on the Internet is when SQL Slammer first hit.
Your density estimate is also off a bit. For example, for Comcast they have published infrastructure stats here, they have an average of 468 homes passed per node. That's houses capable of getting a signal, but doesn't reflect actual subscriber density. They also say they have 102k HFC nodes. Last year Comcast had about 13.5 million HSI subscribers, so 13.5 mil / 102k nodes = ~132 HSI subs per node. |
