50Mbit Service Upstream Discussion

As I think I might have mentioned on the newsgroups it does increase the available bandwidth by a lot of bytes, it just doesn't increase the available RF bandwidth.

1 or 2 x 38Mbit channels usable Vs 1 or 2 x 38Mbit channels and 3 x 51Mbit channels is quite a difference.

Backhaul bandwidth from CMTS to Internet should not be an issue.

DS here is using QAM64 and US is using QPSK.

'Experience' was perhaps a bad word to use, but certainly no point besides hosting in the higher upstream.

Your point was that no game required a higher upload speed. EVERY game on Xbox Live, and any non server game (many) on the PS3 require it. EVERY game on Xbox Live is peer to peer and therefore hosted by one of the gamers automatically, whomever has the best upload. So their point is entirely valid, one of the benefits, and for me it's a significant one, is that there will be the opportunity to play on Xbox Live with lots more gamers in one room.

You implied that it was only useful for hosts, as if that was a minority thing. And it is if you're a PC gamer. But it's a common thing on Xbox Live. The sooner the UK gets higher upload speeds as a matter of course, for everyone, the sooner we'll be able to enjoy Xbox Live or PSN to the full.

So I am wrong when I think of the xbox connection method as peer-to-peer in that each individual person has another connection to another user?

Yes, one person in the game becomes the host and everyone else connects to them.

[Stabhappy]

Not really peer to peer then is it :P

No But people tend to refer to it as peer-to-peer rather than saying that there's no provided hosts.

[popper]

"people tend to refer to it as peer-to-peer " ?,most people call it by its real name though that being the old classic client/server mode

[Ignitionnet]

Upload related thought for the day: Those on the LLU-based offnet package delivered over the much maligned copper wire have better upload speeds than all fibre optic customers apart from those on 50Mbit, and pay £17 a month for the service with evening and weekend calls.

Thought over!

without pulling the marketing apart BB
it's shame VM wont contract for these stand alone CMs as their a few pennys more in bulk...as VM routinely buy....

not that VM ever liked cable modem 'gateways' for the whole house streaming LAN thing and the like many end users have advocated for Years...

Motorola Extends DOCSIS® 3.0 Leadership with New Line of Wireless Home Networking Gateways

Motorola’s innovative SURFboard® gateways help accelerate the migration to a service-assured home with integrated IP services

October 27, 2009


HORSHAM, Pa – October 27 2009 – Motorola, Inc.’s (NYSE: MOT) Home & Networks Mobility business today announced its next-generation SURFboard DOCSIS 3.0 modems and integrated gateways, designed to deliver ultra-broadband IP-based voice and data services.

Motorola’s new gateways help cable operators accelerate the delivery of personal media experiences to their subscribers by making ultra broadband available throughout the home, with one easy-to-install and easy-to-manage device.

As consumers demand more wireless services, cable providers are seeking integrated solutions that combine traditional high-speed data, IP-telephony and secure home networking with unparalleled service assurance.

Motorola continues to be a market leader for DOCSIS 3.0 solutions, and this new platform is two times faster than our previously announced DOCSIS 3.0 products.

The new line of standards-based and remotely manageable gateways supports high-bandwidth Gigabit Ethernet (GiGe) home networking and channel bonding of up to eight downstream and four upstream channels.

This increased 8 x 4 throughput support enables an operator to offer its customers advanced multimedia services with data rates up to 300 Mbps downstream and more than 100 Mbps upstream.

The new SURFboard all-in-one integrated gateways also are equipped with a four-port GiGe switch and integrated 802.11n Wi-Fi® access point.

The gateways’ internal antenna and switched on-board radios (2.4 or 5 GHz) enable consumers to maximize the high-bandwidth potential of their home or business networks, while eliminating the need for stand-alone routers, hubs and access points.

In addition, the new SURFboard gateways are equipped with next-generation security features:
a built-in firewall with Stateful Packet Inspection;
intrusion detection; Denial of Service attack prevention;
and a simplified ”visitor” feature set, enabling users to easily accommodate addition of their “permissioned” guests onto the home’s Wi-Fi network, while still protecting the network from unwelcome hacker attacks. ....
...

I personally prefer having a modem rather than a router, much more flexible. Who bloody well wants switched radios in a router anyway, even my knackered old 3com AP (that admittedly I don't use anymore) can operate in both bands at the same time.

[Ignitionnet]

We may see a different modem being used on the VM network at some point in the near future though not sure about the plans regarding a combined gateway.

That gateway regrettably won't assist with upstream provision, that'll take a bit more than a change of CPE.

[merlintt]

i agree with the op

[Ignitionnet]

Another operator deploying DOCSIS 3 based solutions with considerably higher upstreams than Virgin, notable is that they use the same Cisco uBR10012 that VM use in some areas:

RCN will leverage the Cisco(R) DOCSIS 3.0 downstream channel bonding solution that includes the Cisco(R) uBR10012 cable modem termination systems (CMTS) and Cisco DPC3000 Channel Bonded Cable Modems. The new services will offer peak data rates of 20 Mbps downstream/5 Mbps upstream, 40 Mbps downstream/5 Mbps upstream and 60 Mbps downstream/10 Mbps upstream.

We get our arse kicked by that high tech bastion Portugal as well.
