Cable Co's Want More Control Over Your Network

Moonshine Coward writes: "'The CAT and the NAT' in latest issue of www.cedmagazine.com discusses Cable labs and their efforts to come up with a 'better' protocol than NAT that allows them more control over devices behind your cable modem. Their upside on this...$4.95 per IP per mth. Their #1 concern...people putting in 802.11b hubs and sharing with their neighbors. Fine in principle and if it gets them drooling enough to speed up the deployment of fiber to the home it might be a good thing. However I can see way too many downsides...not least of which is being nickled and dimed to death..my webcam, cable ready microwave, refrigerator, pictureframe that shows revolving jif's ... each costing me $4.95 p.m. -- all on top of regular $39.95 cost." Note: the article is written from an interesting point of view -- it's aimed at the people who want to collect the additional per-IP charges.

MSOs, revenue, DOCSIS 1.0, and DOCSIS 1.1

[DaveWhite99]

I'm sure many of you have seen those hilarious DSL commercials that cast cable-based broadband access in a bad "shared access" light. That's because the current Data Over Cable System Interface Specification (DOCSIS), 1.0, is a best-effort packet delivery system and thus has no guarantees for Quality-of-Service(QoS). Thus, the cable operator (MSO) has no way of throttling bandwidth, especially upstream bandwidth. That's why the MSOs don't like NAT and want to be able to bill their subscribers on a per IP basis. Enter DOCSIS 1.1, essentially a QoS add-on to DOCSIS 1.0 . With a DOCSIS 1.1 Cable Modem Termination System (CMTS) sitting at the MSO's cable head-end and a DOCSIS 1.1 cable modem (CM) sitting at your house, QoS can be guaranteed. That is, the MSO can both limit you to a certain upstream and downstream bandwidth as well as guarantee a minimum upstream and downstream bandwidth. So, given a DOCSIS 1.1 deployment, I see no need for the MSOs to agitate customers with this intrusive CAT proposal, since they now have a way to bill you by bandwidth. Two months ago, the first set of DOCSIS 1.1 products were certified by CableLabs. However, I don't expect DOCSIS 1.1 deployment and replacement of DOCSIS 1.0 systems to happen in large numbers until the end of 2002. Another insider note: CableLabs, the entity pushing CAT, is funded by the MSOs, but has no authority to push its proposals into implementation. Only vendors building CAT products and MSOs buying those CAT products have the power to deploy this ludicrous CAT proposal.
