Re: [uknof] Notice of Claimed Infringement from A.B.C.D at 2019-06-05T06:41:07Z - Ref

[John Bourke]

Hi,

Thanks everyone for the responses.  In summary 

Considering we are at the start of a chain of resellers towards the end 
customer, contractually we should pass these down.

It might be a good idea to segment our immediate resellers onto separate NAT 
ranges (we have one global NAT range), allocate these addresses to the 
resellers in RIPE and then the abuse issues go to them.  We need to give them 
the ability to map back to their private addresses (we operate the 
infrastructure as a service).

The other thing to do is to have a well formed AUP, a reasonable procedure for 
dealing with these, and that would normally be sufficient to show that you are 
making best effort.

Alternatively reply to each of these with a request for more information, if 
you get no response, then ignore.

Thanks

Subject: [uknof] Power Delivery Definitions

Hi All,

I'm not sure if this is an appropriate forum for such a question, so I'll take 
silence as a 'nope'...

At the moment we are having a disagreement with another DC provider regarding 
their power delivery to our racks we are renting there. This started because a 
few weeks ago they had a fault which resulted in a complete loss of power to 
both "A" and "B" feeds to our comms racks for approx. 25 minutes.

They have since confirmed that this outage was caused by: "...a single UPS 
battery failing during a mains failure simulation test, resulting in the 
shutdown of the UPS."

The power solution we are paying for each rack is defined (in their own words) 
as being made up of two chargeable elements:

1 x "Single Phase Primary Power"

1 x "Single Phase Redundant Diverse Power"

Consequently, I now have two issues with them:

"Redundant" - As far as I believe, this implies that a system (such as a UPS 
chain) will be at least N+1 and therefore can tolerate a single failed 
component or UPS. It should certainly tolerate a single failed battery within a 
single UPS within a chain.

"Diverse" - My understanding of this is that it should include power from two 
'diverse' sources. Since both our feeds failed in parallel when this single UPS 
fault occurred. I therefore argue that their solution is not diverse either.

Thus, the overall claim that our dual feed racks have "Redundant Diverse Power" 
is, IMHO, false.

Obviously as a provider ourselves we have our own terms and interpretations of 
power delivery - but I'm not looking to do an 'Us vs. Them' or anything, my own 
view will be skewed anyway. So I'm asking here as I'm genuinely interested in 
what other people would expect their level of service to be after purchasing 
products named exactly as I've shown above, from a large multinational 
provider. (I'm also not interested in naming the provider, that's not what this 
is about.)

I've also been unable to find anything particularly useful online, either in 
terms of backing up my either my understanding of the definitions being used, 
or backing up their interpretations.

I welcome your thoughts - cheers!

I used to visit Virgin Media exchanges from time to time (when they were

every visit for me, pretty much. It wasn't a video - someone walked you around 
the facility: don't touch that. If someone else touches that, do this. etc. I 
think we were the only external customer in the building.

Inconsistency in procedures translates to flexibility in pricing though.

1. Yes.
2. This sounds somewhat “lacking”.
3. And even more lacking.

In another facility I used, there was an inadvertent release of the fire 
suppression system during maintenance (due to a fault with the fire suppression 
system).

Thankfully I was not on site.

I did however, ask, having never been briefed on any of this in quite some 
considerable time using this facility, what the process is, is there a warning 
before it releases, what happens.  I understand this can be somewhat loud.

I complained to my account manager about this, in respect of H angle, who 
said he would get back to me.

Of course I never heard anything more because the trend is that the big service 
providers don’t seem to give a f... these days.

Maybe there has to be a serious incident before DC H is taken more seriously.

Re: [uknof] ISP Security architecture

[John Bourke]

James,

You hit the nail on the head there.

I was trying to avoid overkill.  In Telecoms networks you would have

Management plane
Control/Signalling plane
User/Data plane

Usually these are separated at SDH or ATM level as separate VCs.

The Enterprise view would be to physically separate networks

Internet
DMZ
Core

But in an ISP you are not going to build a physical separate network.

Then the private cloud view is that all of these are together, separated by 
network and server virtualisation.

I think the danger is trying to use Enterprise models for Service Providers, 
where even those Enterprise models are blurring.

Thanks

John

I'm not 100% certain of what you are looking for here but if you search through 
the list archives for the c-nsp and j-nsp mailing lists (others too I'm sure) 
you'll see many discussions about ISPs moving the Internet into a dedicated 
L3VPN.

In that example keeping the internet traffic in a dedicated L3VPN and say 
having a separate dedicated L3VPN for management traffic segregates the two 
traffic types but the NMS/OSS/BSS systems still have access to the routers (if 
you configure them to allow management access from within that management 
L3VPN).

I’m not sure where the horror stories fit in to this that specifically relate 
to the Internet? A decent ISP (IMO) should have good control plane and 
infrastructure protection in place, so there should be no threat. I think the 
main issues from the Internet into the ISPs OSS/BSS systems is DDoS traffic, 
either targeted at the ISP or a downstream customer that fills the pipes and 
they can’t even get management access to their devices (perhaps no out of band 
connectivity for example). But control plane attacks can come from within the 
IPS, not just out on the Internet and can be fairly well defended against.


Cheers,
James.

Re: [uknof] High Density Wifi

[John Bourke]

Folks,

Forgive me if I have not gone through the video.  This sounds like distributed 
digital beam forming.

Beam forming creates a steerable beam.  This is essentially using two 
transmitters offset from each other to create interference patterns that 
positively coincide at a desired location.

There is a lot of processing involved in this which makes the hardware 
expensive and complicated, pretty much implemented in bespoke silicon.

In software you have less worries, processing is cheap, so why do it in 
silicon.  This is called Software Defined Radio, although SDR which was 
originally conceived for handset and not base station optimisations.

We have already seen cloud RAN technology where the radio node is stripped down 
and the RF processing is aggregated at a metro site.  Trade off here is that 
you need dedicated fibre between the RF head and the RF processing, but in 
Metro areas this is possible.

Mix beam forming, SDR and cloud RAN together and you can have large arrays of 
digital beam forming nodes, with central processing.  The processing must be 
central to allow for coordination of multiple beams.

As ever in RF there is no free lunch, you pay in back haul and processing.  But 
you are up against the laws of physics, and something has to give in order for 
you to scale.  Technology is already giving way to cheap fibre and cloud 
computing so at least this type of RF design is riding the right trends.

The cheap fibre is in urban areas and we are trying to solve an urban customer 
density problem.

If you now scale this up.  You only need as much processing as you have active 
customers, these customers move, and in crowds, so why build the processing at 
the edge of the network in the base station where some locations will be 
massively overloaded and some empty.  Better deploy cheap simple base stations 
and process near the edge.

To quote Douglas Adams, this technology is fiendishly difficult, but there is a 
real problem to solve so the money is sure to follow.

They seem to me to be requiring many base stations, they are attempting to 
virtualise the concept of cells, but their technique *requires* more than one 
base unit per handset, as a minimum, to work. 3 in the case of 8 handsets, 8 
bases in the demio of 16 handsets (I found another vid on youtube  
https://www.youtube.com/watch?v=MZnKYHC6rn8 )

I'm not sure how many handsets any given number of bases can support, but I 
took it that they are looking to saturate an area with their base units to 
provide geographical spectrum re-use as well as active techniques to help.

Yeah I was wrong about the P2P, sorry. I was assuming that he was trying to 
demonstrate near-field coupling of the device antennae within millimetres of 
each other (he laid them up against each other in a toppled stack-like 
arrangement - just on from here in the vid I watched first.

 https://www.youtube.com/watch?v=5bO0tjAdOIw#t=1699

Since P2P via nearfield was the only way to allow device-to-device comms to be 
useful at anything much from a delivery standpoint, it was all I could think of 
:)


What this really needed was a simple statement or paper that the minimum rcvr 
separation is Xmm apart, because the sum of waves can only be calculated and 
synthesized to a resolution accuracy of Xmm for X devices that are stationary 
for a given period of X(milli?)seconds. I'd like to see how that scales in a 
street full of people moving at various velocities and vectors with other 
reflective objects like buses, trucks, cars, moving at typical velocities, in 
addition to the normal intense multipath environment of a city street (which 
naturally and in a very complex way creates the intense additive and 
subtractive phase difference environment that they are utilising, plaguing 
urban communications, acoustic as well as RF)

It seems to me to take a lot of back-end grunt to work currently: 2 servers 
running to provide 8 devices, so the claim about 1mW of power can only relate 
to the TX output power, which is far less impressive from an RF perspective. It 
was this specific statement I happened upon that led me to question the RF 
engineering experience of the presenter.
I've also watched a second video where he seems to be confusing spectral 
bandwidth with throughput - https://www.youtube.com/watch?v=MZnKYHC6rn8 ;  the

of the video streams first. It could be extremely technically

Folks,

Sorry I missed you guys at the recent UKNOF day.

We are about to take receipt of a stream of satellite image data at a rate 
150Mbps, growing to 600Mbps over the next four years.

This then needs to be redistributed to UK end users on an on demand basis.  So 
if we get new interesting images (like pictures of where planes might have 
crashed in the Indian ocean) then we could get a lot of demand.  Our peak to 
average ratio is likely to be massive.

As we only have a mandate to distribute to the UK, I am thinking that I can 
just peer with UK ISPs and deliver the data to their customers.

So the plan is to lay in 2x 10G into London and interconnect to one or more 
exchanges via an exchange aggregator.

If anyone had any thoughts or comments on this, I'd love to hear from you.

Thanks

John

Re: [uknof] Automatic / Zero Touch Device Configuration

[John Bourke]

Hi,

If you don't find anything, I could have a go at it with some tools which do 
automated Linux builds.

So what is everyone doing with regards to auto configuration of devices such as 
Cisco routers?

I'm going to roll my own probably coding something from the ground up if its 
possible.  Its for mostly Cisco kit. I want to avoid having routers and 
switches sent to the office, configuring them, then shipping them to their 
destination. Its a big waist of money just to paste a config on.

I have two questions really, is anyone doing this already (what software/system 
are you using to do this, is it open source, paid for?) and how does it work? 
Often blank Cisco devices say something like press any key to tftp boot then 
they drop into rommon mode. How are these systems/your systems kicking the 
routers to download an image and configuration?

Once the config is on in fact I can upload a new image remotely so its just the 
config that is really important. I'm talking about shipping routers to on-net 
locations, CPEs and PEs.

The only idea I've had so far is to try and reverse engineer an IOS image to 
change the default TFTP location to an internal system. Also different devices 
act differently with regards to that initial configuration process so the 
system shall have to allow you to  choose from a variety of method per device 
etc.

Cheers,
James.

P.s. I have read up on autonomic networking but that seems some time away as 
yet, please correct if I'm wrong.

Re: [uknof] Rack Space in THN

[John Bourke]

Folks,

On the same subject, I am putting 10G's into THN and LD4 in order to connect to 
LINX.

What I would prefer to do is to build a small meet me point before hitting 
LINX.  So I would need a quarter of a rack at each site.

Is this even possible ?

Thanks

John

Hi John,

Whereabouts and how much, we're looking for another rack in THN (Clearstream 
Technology).

Cheers,

Paul.

Not sure if this is of any interest, but we have an 8 amp rack coming available 
in the next 4-6 weeks in TFM3, Telehouse North.

If anyone is on the look out for space please let me know off list

Jon

 Any idea what customer site DWDM equipment costs for 4 or 8  wavelengths ?

About £3.50 and a packet of rolos. :)

Do you want active or passive? What speed are you running the waves at? Do you 
need low-loss splitters?

Too many variables to answer sensibly.
