Docsis 3?

Riaz Kanani · 1 year ago

Docsis 3 is the technology Virgin Media are using to achieve the 50Mbps speeds (scalable up to around 100Mbps).

It is employed by many cable television operators to provide Internet access over their existing hybrid fibre coaxial (HFC) infrastructure. Docsis 3 was released in August 2006.


"...if they can innovate and take advantage of their bandwidth scale then there would be little the other broadband providers could do.. except Sky."



What is Sky going to do?

Sky have the ability to use their satellite connection to deliver large amounts of content - they can therefore get more from the 24mbps connection than the other providers can - of course they are stuck on the upstream.


But you got me thinking further - Sky would also need to use the same ADSL 2+ connection for video on demand, which if HD quality, would chew through a lot of that bandwidth too. I had forgotten they can't do VOD.

Have you taken a look at Cachelogic? They cache popular content for ISPs at the edge of their network to help reduce those running costs. For me this is a better place to cache content than on the edge of content delivery networks like Akamai.


Of course I have no idea how well that can scale - but its a first step towards reducing the costs of delivering content using an IP based network.
