PON in my view is well suited for residential distribution and use profiles.  
10G/XG-PON at 10gig/2.5gig is a pretty serious residential connection and even 
2.5/1 is pretty great for residential 1/1 symmetric service.

That said, I would in urban environments not recommend designing for GPON 
physical cable plan - go AE on your cabling.  Play with PON if you want more 
headaches here with little redeeming features IMO.   Instead, design 
rings/meshes, and think redundant/diverse path and entry/distro.  There’s a 
reason telco standards work. These days there’s little reason to separate 
residential vs commercial traffic, it’s all packets at our scale.  Our core is 
agnostic and switches anything we throw it at hardware speed, and it’s HA (min 
2 core routers in every POP - even some customer buildings have 
diverse/redundant fiber entry from us now, back to multiple $alldayallnightjob 
POPs no less, in some cases to meet regulatory minimum standards compliance.  
All of our DCs are built this way.Fact is, if you want a network to be fast 
as hell, and never ever go down, think redundant everything with diversity.  

That said, for rural distribution, especially cheap aerial residential services 
in far flung locations - there’s literally nothing finer and faster and more 
cost effective than GPON - which is HUGELY important for reaching the final 15 
MILLION Americans that do not have broadband internet connections at all.

For those people, GPON can be nothing short of utterly life transforming.

My assumption is that you'd be running full IP/MPLS all the way into the
Access. In that case, what I'm saying is that you can run EoMPLS to
deliver the service.

RE: VPS providers contacts

2019-02-08 Thread Ryan Hamel
Mehmet,

On our network automation, we “drive” each product through SSH/telnet and use 
the native terminal or netconf. This automation has been around before netconf 
was a concept, anything new is simple as writing the configuration snippets, 
creating the functions in the abstracted automation classes, and overriding it 
in vendor model specific classes.

This same template idea could be used to generate BIRD configurations that can 
go into a pre-defined folder from the main config file, and trigger a soft 
reload. I personally can’t wrap my head around BIRD since I came from the 
traditional network hardware background, but it certainly does have its place 
in the automation sector.

Just make sure your system has a way to log each step from the device and 
program functions for checks and balances, and combine it all in a transaction 
like process, along with throwing an exception on data it doesn’t know to 
expect, and rolling back the changes if it’s possible.

PON is the lifeblood if many rural communities. I'm luckily to have a 
healthy mix of PON and AE operations since I'm located next to cities. 
But I've met cooperatives in the middle of no where with super low 
density where it's 6 people + 2 donkeys on staff. AE would never work

Unless someone wants to give enough funding to run AE to people's homes, 
PONs will continue to allow many communities to have more than cellular 
internet access options, if that.


PON and AE both have their strengths and weakness and make sense for 
different deployment scenarios. My biggest problem with PON is that it 
seems some operators build their fiber plant for PON for all deployment 
cases and then it's extremely hard to back out of it and switch to AE. If 
you have AE you can switch to PON fairly easily, but not the other way 
around if you've put splitters in the manholes.

For a lot of us, PONs are a way of life and may not even have any 100G capable 
devices in our network, muchless enough to make our money on. While you may be 
so "lucky" to "never really take it seriously", it is supporting hundreds of 
thousands, if not millions, of homes in the US.

PON is the lifeblood if many rural communities. I'm luckily to have a healthy 
mix of PON and AE operations since I'm located next to cities. But I've met 
cooperatives in the middle of no where with super low density where it's 6 
people + 2 donkeys on staff. AE would never work there, but PONs allow them 
cheap and available broadband options.

Unless someone wants to give enough funding to run AE to people's homes, PONs

We do 1 gig over pon (gpon)...Calix E7 (olt)

Yes, it's my understanding, and I agree with previous post response, that PON 
is for using 1 fiber strand to a home (bidir , different wavelengths for xmt 
and rcv) and then I believe it even gets prism'd (however the heck they do it) 
into a 1/32 split or something like that so that you don't have to run direct 
fibers from every home back to the CO

...AND, in a rural area, geez, those are lggg fiber runs so a pon 
cabinet in the field helps greatly

Yes, 2.4g down and  1.2 g up is a concern when you've sold (oversubscribed) 
more bw than that 

We are concerned and looking for ways to overcome this and keep up with 
subscriber bw demands all the time ... fun and job secure

Many years ago, I did consider running both Consumer and Enterprise
traffic on one router - and for purposes of pride, I'm sure the major
vendors would like to boast that they could allow you to do this. But in
practice, it's probably a bad idea... BNG's have too many moving parts,
and for some platforms, there is actually special code optimized for BNG
deployments that may have an impact on traditional Enterprise or Service
Provider customers.

So I would separate BNG's from regular edge routers.


Enterprise DIA is a whole different beast.  For sure, that stays 
separate at least for now.  Some of the forthcoming PON technologies 
have so much bandwidth that it may become attractive to start merging 
them at the access layer for smaller customers, and then I guess we'll 
have to see what the best way to handle L3 termination on that is.


If anything, just ensuring that the (often) separate tech teams have the 
proper access to it and knowledge of what the others are doing might be 
a bit of an issue.




If you're in a position where you want to or have to offer competitors
access to your network to sell service directly to customers, that's
also going to potentially really change the situation.


Why? Chances are they will require Ethernet access between their
customer and their head-end, which is a typical scenario.


I'm thinking that, if you push L3 termination all the way out to the 
last access node (FTTN DSLAM being the obvious one here), you may then 
lack a decent way to haul pure Ethernet back to their head-end.  If your 
L3 termination also supports MPLS, or Q-in-Q, you're probably fine.  The 
latter might negate the potential advantages of distributed L3 from a 
routing POV by forcing you to again run STP or similar.


If you're doing L3 termination a bit more centralized, even if not with 
big behemoths on a "one per super-metro" basis, this may not be a 
problem at all.  HFC and FTTx PONs might end up being like that 
inherently just because of the nature of the plant and tech that runs on it.
