Comcast Deploying Upstream Channel Bonding
Meaning Faster Upstream Speeds for Many Users
by Karl Bode 06:07PM Monday Jun 13 2011 Tipped by FFH5 See Profile
For some time, DOCSIS 3.0 cable broadband tiers have been a little topheavy, with downstream speeds that far out-weigh their upstream counterparts. As we've been discussing, that's about to change -- given Comcast has been testing upstream channel bonding for some time, and has seen upstream speeds as high as 75 Mbps in the labs. Comcast had stated that the technology should production ready by the end of March, and now users in our forums indicate they're seeing bonded upstream channels in the wild. Users aren't seeing significantly faster upstream speeds yet, but they do seem to be seeing more consistent upstream speeds -- and the upgrades will ultimately lead to more impressive upstream bandwidth. Deployment seems entirely random, with users from California, Florida and Indiana all noting the change. We've reached out to Comcast for more detail with no response, but we'll gladly post any additional information we receive.

Re: Got two upstream channels....

Same here on my 50/10 service. But, I get a consistent 12-13 up on two channels versus 10-11 up on a single upload channel. 20% increase is okay. I'd like to see a 75/20 upgrade.

Re: Got two upstream channels....


4 downstream, 1 upstream


This is pretty typical for 4 down and 1 up channels for me.

I have 50/10 business class, so I wonder what/if they will change it up to when they have deployed it?

Good luck trying to get this for $65 like in the northeast where there's competition, try around $100 or higher!

Based on CMTS model?

Maybe the seeming randomness of the rollout may be because they are only testing it on a particular model of CMTS?

Hit your Comcap even faster!

Now your download speeds and upload speeds can conspire together to hit your monthly bandwidth cap in half the time!

Comcap's 100 Mbps packages can already hit the bandwidth cap in 6 hours... so once Comcap rolls out symmetrical 100 Mbps you'll be able to hit your monthly quota in just 3 hours! What a deal!

You're just jealous cuz it takes 4 times as long on pewverse to hit your 250G caps.

There is no cap on business class.

I want to see how much Comcap's symmetrical 100 Mbps business class costs... or how much even their 50 Mbps would cost...

Right now you can get a grossly overpriced 12/2 Mbps package for like $70 a month... anything faster than that hits three figures territory.

Business class is not the solution.

for no cap? yes it is. The kinds of speeds we are seeing are higher than we should be getting for the same pricepoint. if you want an SLA and not best effort(which is what the $70/month tier is) you can get it from comcast..at 10x the price.

Why? what do other providers want for the same speeds at your location?

When ATT announced caps I checked out both Comcast and U-Verse business class service before going to WOW residential service. Comcast was the cheaper of the two (Comcast 12/2 vs U-Verse 12/1.5) and after looking at the speeds I get with WOW, I'm sure the speeds with Comcast are higher than advertised. My U-Verse service always had speeds lower than the tier advertised. I had U-verse 3/1 and 6/1 and never got those speeds (they were 2.8/.9 and 5.7/.92). I have WOW 8/1 and get 8.5-9/1.1-1.2 for $10 less per month (when including the top tier phone services)!

If WOW ever caps, I will go to Comcast or WOW business service. U-Verse will never be able to match the speed/price ratio as long as they use aging copper to the home. And the prices aren't all that good either.

Promotional Upgrade

I recently noticed that my modem was bonding the upstream traffic, however, my speeds are still the same... I reckon that haven't changed the throughput cap. Coincidentally I received a call from Comcast saying that I was going to be upgraded to the next tier(from 12 to 20Mbps) for free and that a tech would need to go on-site to test it.

Regardless I took the offer... so we shall see what speeds I get this Friday.

It's here in Sonoma County, CA

Got it here last month. This is what I'm getting on 4 downstream and 2 upstream.




Some areas have 3 upstream channels.

This isn't a speed boost. it however will help nodes with high utilization on the upstream side

Upstream bonding matter of fact and around for a while

San Jose tech implied all SMC business routers (and straight out said mine) should have three upstream, as a rule. I've had bonded upstream for many months on my SMC. The only speed increase is with upstream powerboost, then it evens out to the quoted rate, but I think it's also more stable and has more headroom to work.

Apparently, this must be a "local" thing; San Jose is a million people, with probably a fair amount of DOCSIS 3 users in that pie, so massive generalizations from techs referring to "everyone" can easily be simply one city only with only those users using DOCSIS 3 modems, or even certain subbrands of DOCSIS 3 modems, and still be passable as being referred to as "everyone".

Bonded upstream channels in Cupertino, CA




Here are a couple of speed tests I just ran. I am on the Performance tier which is supposed to be a 12/2 connection and checked my modem config page (Motorola SB6120) and it looks like I have 3 bonded upstream and 4 bonded downstream channels.

The last time I checked was when I had the service installed and I distinctly remembered seeing the 4 bonded downstream channels but only 1 upstream channel.

Upstream bonding in Raleigh/Durham Market

The TWC new DOCSIS 3.0 upgrade in Durham NC is channel bonding 2 upstream and 4 downstream for me on the UBEE DDW3611 they are offering. Capped at 5mbps upload for their plans though.

Just checked mine and noticed channels 0,2, and 3 upstream show power levels now. I'm on the Blast 20/4 pkg with a DPC 3000 modem.

None Here Yet..

Been waiting for over 4 months now for DOCSIS 3.0 Network Upgrades and have yet to see anything. Extreme 50 is in my area and I can upgrade to it but there no point when I'm already downloading at the max on a DOCSIS 2.0 Network.

I'm in Port Huron, MI and have had a DOCSIS 3.0 modem for 4 months. I have Blast /w power boost. I've called Comcast a few times to ask about it and was told last month that we'd see upgrades happening this month or next and before this month started like at the end of last month the network went down for 4 hours or so for 2 days (Not the same days it was different days) and when I called Comcast to see what was going on the message said something about there Software/Server upgrades ect.

So I'm still hoping for some green lights.
