Why the NBN satelites are needed

[Mattus]

There are a lot more cables than that, much more capacity

Apparently there is a lot of dark fibre around the world.

As I said, I was actually including the dark fibre in my estimation. The current bright fibre capacity of Southern Cross is only 295 Gb.

Will try and get some data on those cables.

Great! I'd actually genuinely like to be wrong on this.

not everyone will be on to the US

No, not everyone, but presumably more that 12,000 people

We will need to distribute core data to be physically closer to the end user. Like have a cached copy of all non realtime data in each country asa minimum. I think Goodle do this anyway.

But in fact the opposite is occurring, Google does have an Oceania data centre, apparently in Sydney, which is used for its search engine cache, but all the gmail, youtube and document cloud data is still kept in little chunks in data centres all over the world. Worse still, the Oceania data centre will be moving off shore meaning the load on cables heading into and out of Australia will increase, rather than decrease.

This, coupled with the trend of many organizations to move away from locally hosted data to using services like gmail, cloud and google docs means more and more previously local traffic heading offshore. So the problem is getting worse, not better. It's no small discrepancy, doubling the capacity won't do it. Software improvements may see a 4 fold improvement in speeds with the existing cable. But we'd still need to lay 25 times more cable than we have under the sea. That would cost $40 billion.

Might be of interest. More cables to Asia than direct to US

And this:

Capacity Upgrade
Once again we have taken advantage of the very latest developments, to rapidly expand our supply well ahead of demand and to reduce our prices” Pfeffer says.

This is our fifth major capacity upgrade since 2001. After trialling a number of systems, in October 2011 Southern Cross signed a two stage capacity upgrade contract to deploy Ciena’s 6500 Packet-Optical Platform and 5400 Reconfigurable Switches as well as Ciena’s OneControl Unified Management Systems. This first phase uses 40 Gigabits per second transmission equipment on our network for the first time.

This move to 40 Gbps from our existing 10 Gbps platform will be short lived. The rapid pace of technological improvement will allow Southern Cross to implement Ciena's 100 Gbps transmission equipment with a simple line card upgrade by December this year when the second phase of the current upgrade is due to be completed. The upgrade simplicity gives us a rapid time-to-capacity advantage.

Our network's total lit capacity is now 1.4 Terabits per second. By March it will increase to 1.6 Terabits and by December to 2.0 Terabits. We have the potential to go to at least 6 Terabits per second by December next year, about 25 times higher than the original design capability in 2000, and our potential is expected to increase dramatically over the next few years. [My emphasis.]

“The implementation of 100 Gigabit equipment this year is some two years sooner than previously anticipated and it demonstrates how the potential size of our network grows in huge leaps,” Pfeffer says. “Some have said there won’t be enough capacity for hi-speed internet growth, but as our expansions and the ongoing rapid advances in technology show, that couldn’t be further from the truth”.

Most of these cables are now fibre. The TCP protocol is being amended to allow faster transmission with less transmit/receipt packets and less resends—will look that up too.

New Telstra cable:

Telstra spokeswoman Kate McKenzie says the company will then sell off some of the cable's greater internet capacity to other internet service providers.
"It's really crucial for the future - we're seeing the rate of data transported from the US to Australia and back again doubling every year. Sixty-five per cent of of our internet traffic comes from the US," he said. -

"he said" ?????

Why the NBN satelites are needed

Because China needs target practice?

Turnbull continues lying about the NBN:

[Neferti]

Why don't you Lefties ask Turnbull to change sides and take over from Jules? We righties don't want him but you lot say you would vote for him.

[IQS.RLOW]

As wet as Turnbull is, even he would recognize that labor is fucked for at least the next decade or more.

The man is a professional and wouldn't fit in amongst a bunch of backstabbing lying incompetant dickwads that is the labor party

Every day that goes by proves it

Turnbull is without doubt the smartest in the Lib camp, but then he was the 'Spy Catcher' QC who embarrassed MI5 and so made himself unwelcome in Britain.
He may appear or even be the most moderate in the Lib camp, but I'm genuinely glad his attempt to become PM (with Howard's blessing) failed, because despite being the smartest of them, he's also the most dangerous.

Dangerous? .. WTF are you on about you ask?
Well, he's been pretty good at hiding the real reason he got into politics in the first place.
Y'see Turnbull's personal agenda is water privatisation, but we haven't heard a word about it for about a decade or more now.

First he hijacked the Australian Republic referendum for an opportunity to alter or remove s.100 of the Australian Constituion (in Chapter 4 - Finance & Trade) which expressly forbids the Commonwealth taking control of rivers from the states.
Then he got into politics proper, with the express purpose of becoming PM. Again for an opportunity to fiddle with laws and/or the constitution regarding ownership and control of water resources. And the Libs dumped a sitting member to give him a safe seat.
He even got Howard to create a psuedo-cabinet position/port folio titled 'Office for National Water Policy'. But when dumped as Lib candidate for PM, his interest in being an MP waned.

Sure, he's a talented lawyer, but I certainly wouldn't trust him when it comes to our most essential resource, because I think Australian water should be owned by the Australian public, not foreign water companies.

Righto, you carry on slagging off the cable network now, as it does seem to be being quickly superseded if not obsolete.

Y'know I don't see much point in spending tax dollars on something being outdated.
Particularly when it'll just be sold off to privateers like Telsra and Commonwealth Bank, for far less than it cost us to obtain.
