They'll add more line cards, aggregate more ports and you'll see that 3.5Tbps capacity figure climb.

 

Good to hear things are not on hold and they will continue through this time with the current day policy of congestion free network.

at a rough estimate.... 50% of people using netflix/prime/etc are using VPNs to other countries, rendering local CDNs under utilized

 

 

That is a _RUBBISH_ estimate. T\he vast vast vast majority are using onshore accounts and CDNs.

I would probably agree. We could take a poll here, but users here are probably much more likely to have a VPN to use overseas Netflix.

No offence taken :) Ok so maybe 50% was an exaggeration but alot do.....

 

My point of my original post was... we would run out of international bandwidth long before we would run out of domestic bandwidth...

Not even a lot... Very very few use a mechanism that would result in the local CDNs not being used. If I had to estimate based on some actual experience I would say well under 5% - probably more like 1-2%...

3tb/s is some pretty impressive amounts of data no matter what way you slice it.

Still not really the correct answer though..

 

RSP's know what percentage of their traffic is national / international and the simple fact is there will never be a problem with international bandwidth. Not now, not next week, not next month. Long gone are the days that international traffic leaving NZ to the US and beyond made up the bulk of internet traffic.

Here is an example for a typical customerbase of 90% residential 10% business. 

 

During the day, approx 50/50 traffic split between NZ and AUS/NSW. 

 

At night, more and more people are watching the same content - netflix, popular youtube videos etc that are served out of caches in NZ. 

 

Especially note the 8-10pm timeslot. Its 25/75 split. 

 

The amount of traffic coming from australia doesnt actually increase much but with more people watching the same content, savings are made by local cache and CDN nodes.

I assume that is a stacked graph? As I assume it is so if you swapped Backhaul and AKL it would show domestic.

 

I would guesstimate these days traffic is around 35% international and 65% domestic off CDNs as CDNs took over from international traffic at least 3.5 - 4 years ago and have grown since then.

From an extremely informed position, don't worry about this. All major streaming platforms are reducing their bitrates over the next few days (Although I don't think Pornhub is!) and I realistically expect peak streaming traffic volumes will be at OR BELOW normal levels in a few days.

 

International traffic is up, but it's not critical.

 

If there IS congestion (and I DON'T expect anything widespread), the CDNs all are able to detect this and they will reduce their bitrates further in order to make way for other interactive traffic.

 

Finally, TCP itself performs reasonably gracefully under increased latency/jitter and minor packet loss. Some realtime applications (games/voice) might not use TCP but they have their own application specific measures built in.

 

Remember, the ENTIRE INTERNET has been built as a best efforts service since its inception... Dealing with congestion, packet loss, increased latency and jitter is BAKED IN to every level of the networks.

 

Just like supermarket shopping, I expect everyone to panic, but just try and act normally - the Internet here in NZ will be fine.

 

Cheers - N

 

 

 

 

Oh great. you mentioned just like the supermarkets. now I know we're screwed!!!

I don't know if it's relevant to do that anymore - the libraries for NZ/Aus content seems to be a lot better than the likes of the US - It used to be reversed, I know.. but the only thing I really use these types of services for now is hulu, and there's not a whole lot going on there right now

Sorry Yes its a stacked graph: International + AKL-IX + NSW-IX = Backhaul

Depends upon what you consider quality. 
Mindgeek content (Pornhub) is still served out of the US but the word around the server rack is they are opening a node in aussie next quarter.

I would disagree here. Netflix are probably the most aggressive in blocking VPN or proxy user access so my thoughts would be very few people are using that method for accessing Netflix. The various VPN/proxy servers are having problems accessing Netflix US and that's for the tech savvy users so it's difficult to imagine how the normal user would be doing that.

If my understanding is correct then for businesses using cloud services, pretty much the traffic is going over to Australia since Amazon, Microsoft and Google data centres are there.  As an aside there is a strong argument for those companies to have local nodes so we are not so dependent on the Trans Tasman cables.
