The Twin Cities are the lucky guinea pigs for Comcast's new high-speed internet

Verizon's FiOS fiber broadband connection is currently the only option for United States Internet surfers to wander about the world wide web while downloading content at up to 50 Mbps and uploading data at up to 20 Mbps. However, Verizon's FiOS service is limited to a few areas at this time, even though roll-out is being performed slowly but surely.

Recently, Comcast also announced plans to increase the maximum bandwidth of its broadband service to 50 Mbps download and 5 Mbps upload bandwidth to compete with Verizon.

Currently, Comcast is running its broadband service aalong the DOCSIS 2.0 protocol, or the second generation of the Data Over Cable Service Interface Specifications. This protocol tops out with a maximum downstream bandwidth of 42.88 Mbps while the maximum upstream bandwidth tops out at 30.72 Mbps.

For Comcast to increase its bandwidth, it will have to begin using DOCSIS 3.0 compliant hardware. The initial DOCSIS 3.0 specs will utilize four channels over cable; which allows the compatible hardware to serve twice the amount of data per second than DOCSIS 2.0's dual channel design.

Through the 4-channel design, DOCSIS 3.0 compliant hardware will allow a maximum of 170 Mbps and 123 Mbps downstream and upstream bandwidth respectively. To achieve this higher bandwidth, Comcast must upgrade its back-end infrastructure to to hardware complaint with DOCSIS 3.0 and must also provide upgrades to customers' leased modems or offer new hardware that is capable of supporting DOCSIS 3.0.

The high-bandwidth options from Comcast are in trial in Minneapolis and St. Paul, Minnesota but Comcast states it will begin mass rollout once the design has been finalized and ready for use over its nationwide infrastructure, which Comcast's president of marketing and product development states may be by 2010.

Meanwhile, Verizon has brought its fiber-based broadband connection to a number of markets in the U.S. If Comcast goes through with these speed increases, we may hopefully see some long-awaited price wars in the broadband industry.

Pricing for the 50/20 Mbps download/upload package is stated around $150 and is only planned for the residential market. Business owners may have the option for a higher-bandwidth package in the future, however, no pricing information has been made available at this time.

Well, I was going purely off of specs and pricing. I obviously can't go off of experience since the 50Mb service from Comcast isn't out yet, so I guess it's just more crap from you since you obviously couldn't have had it either. Sucks that you have a download cap, but I've never hit one and I've downloaded well over 100GB some months. I couldn't say exactly since I don't usually keep track. I'd say it got close to 200GB if not over.

As for "PowerBoost," how is it going be be in a cache? I highly doubt they cache EVERYTHING you know. I know that sometimes it does that depending on what I get. It's usually the things that I redownload that make it seem obvious, like when a 20MB file finished instantly. I know it's not my browser since I have the cache set to only a few MB. On most files though it seems obvious that it works like it should. Even if it is cached, which is doubtful, it sure isn't caching it on any computer in this house. If it's caching it to the modem then whatever, still means faster DLs for me which equates to a shorter wait.

I think you're just pissed at Comcast cause they screwed you over. Hell, I would be to.

Reading specs? Check the fine print. "up to", dependent on time of day and network traffic, unspecified caps...

The point of cache isn't to hold everything. If you had an inkling or insight here you might have a clue. Network caching is designed to capture the mostly common items in cache boxes around the network for quick access. The software on your local machine is nothing more than local cache that bloats your system and eats resources, hence yoru 20MB instantly being downloaded. Its more bloat ware. You can accomplish the same thing by adjusting the cache on your web browser and getting a real download client. Get a clue moron.
