Southfield, MI | Yes, but I am annoyed by all the traffic on my cable con when my dsl is silent. When the lights flash on my dsl modem chances are i know what is going on. My cable modem is constantly going. | |

Perfectly normal, and harmless.

I cannot speak to the exact technical reason, but it was explained in detail by a network admin in the Cogeco forum a while back.
(I couldn't find the link)

It's all shared at some point.
That IS the general idea of how networks operate. But, for those of you who are protocol challenged, a protocol like CMTS that is shared at layer 2 without any deterministic qualities like a TDM network makes a whole connection act like garbage when enough other stations on the segment are busy. Most DSL providers on the other hand are typically using ATM at layer 2 with either PPPoA or PPPoE for the client connectivity. This provides a whole different class of connection quality that is scalable and fully manageable by the providers. Cable providers don't have that flexibility on their networks and have little ability to control the congestion in their networks at the edge except to enforce harsh ToS agreements to limit upstream traffic. DSL's downfall is usually the physical limitations of the wire to the customer's premises. Luckily for the cable companies this is something they don't have to worry about. Everyone can connect just the same. They just have to try and control upstream bandwidth usage without a technical way to do it with the access protocol to avoid upstream congestion within their nodes.
Shared interfaces at aggregation points like 100Meg or Gig or OC-3, OC-12, OC-48 etc. are a complete world apart from the shared technology behind the DOCSIS standard. You are trying to compare shared service within an access technology versus shared service within a core network technology. So you can't even begin to compare these apples and oranges. Obviously speed of those technologies is a factor. But, aside from the speeds, the methods of traffic queueing that can occur on those types of interfaces, depending on the layer 2 protocol, is like comparing a Ferrari to a Pinto. When you aggregate thousands of broadband connections into upstream network connections that are shared in this manner, that is whole different kind of shared connection than cable uses.

| Re: Poor Babies Yes, that is the technical way of looking at things.
I look at the speed test archive here at dslr:

Judge for yourself.
Theory vs execution!
(As was said earlier, either DSL or Cable can be done well, or done poorly.)
