FTTx - Broadband Solution Overview - PON - OLT - ONT - BNG - Network
This is an overview of a Fiber to the Prem solution - what happens from when you order the service to how it is deployed. It talks about how you used PON Controllers, OLTs, and ONTs to bring up Ethernet. How the BNG brings up Internet Connectivity and how RADIUS is used to authorize a subscriber, manage bandwidth, and support Lawful Intercept. It discusses the requirements on the network and how those can be met. Finally, how does the technical solution fit into the ISP's business requirements.

Thank you
Thank you🙏
very useful, thank you !
Glad it was helpful!
You got the choke part backwards
Sorry!
💯
Excellent insight, real world examples help a lot.
Glad it helped!
- what are the typical/most common use cases and flows - the most important whys of a standard, why is it needed - what is the most important concept(s) to grasp about the topic, the role it plays in a larger whole this is my attempt at clarifying what i as a learner want from a video like this. i think you speak clearly with a nice pace, but wish you substituted some of the details for a more contextual take on bgp and best path selection in the real world. hope you consider keeping this in mind when making more videos, i really find your presentation clear and concise. thanks for sharing your knowledge.
Excellent, thanks
Glad you liked it!
Smart way to make your stuff last forever. I always shut down once in a while machines this way. Generators, etc.
Or you could just use the actuall kill switch like its intended for?
This video was very clear and thorough, it helped a lot. Thank you!
You're very welcome!
This is a really good one, not just tells you stuff, but also strings all together. It is really good for people to go over the mpls related knowledge. I watched three times.
Thanks! I’m glad you found it helpful!
That was helpful, thank you indeed
Glad it was helpful!
Excellent explanation of something I’ve always misunderstood.
Great to hear!
Well Explained .. Thank you. So much
So nice of you

Glad it helped!
Great video! thanks for sharing
Thanks for watching!
Excellent explanation of Multicast, Thank you.
Glad it was helpful!
does the rendezvous point keep changing when more igmp joins come in at some later point in time from different switches ?
Thank you.
You're welcome!
Perfect explanation, loved it!

How do you store this snowblower for winter? Is there a tutorial video by him? He does a great job.
No video but I asked him. He said, First, I recommend always using gas already mixed with gas stabilizer for things like snow blowers/lawn mowers/generators so that the gas is still viable after the winter/summer layover. Then just be sure to follow your usual shutdown procedure where you turn off the fuel petcock and let it run until it stops to make sure there’s no fuel left in the carburetor. If the tank is nearly empty, you could run it dry to be sure that there’s no stale gas, but if the gas is less than a year old and you used stabilizer, it should be fine.
@@BarbaraAnne A belated thank you! I hope he produces more videos.
This video really tied it all together for me after watching/reading dozens of sources trying to explain multicast routing and still struggling to understand how it all works together. Superb presentation! Thank you for taking the time to share your knowledge.
Great to hear! Thanks!
Great explanation of IP multicast. Thanks!
Glad it was helpful!
Great, is there also a video about Software PTP so with with no PTP Hardware and if using Software PTP if a acceptable choice when going for low latency in a small lab enviroment?
I’m not quite sure what you’re asking but there isn’t another video. Sorry
That's awesome, thanks for sharing that
Glad it was helpful!
nice and well explained !
Thanks!
Appreicate it. Maybe you can also upload a video that explains each header. I believe Segment Routing Label is your transport label and PW label is a VPN label signalled by TLDP or eVPN. However I am not aware what is control word :) Thank you for your posts
Thanks for the idea!
It's surprising for me to learn your channel. Excellent video. Appreciate it
So nice of you!
Thank you for your video. Got my blower started with your directions.
Excellent!
Good video, Mutlicast mac seems wrong
Thanks. Ethernet addresses with a 1 in the least significant bit of the first octet are treated as multicast traffic. So the 01: makes it a multicast address. Thanks for the feedback.
@@BarbaraAnne shouldn't it be 01:00:5E:xx:xx:xx ?
Im a telco guy, you didnt include the evolution of PDH to SDH then NGSDH to CWDM to DWDM and now OTN. We actually have more optical transport on the local networks than long haul. The IP and Ethernet guys always believe that their P and PE routers are directly connected via fibre over a 10Gbe port which isnt always the case. ROADM isnt cheap because its design is multiplexed similar to SDH and you need to build a ring and cannot just do a hub and spoke as per the older passive DWDM networks for best practice. Its also not economical for enterprise transport because the client ethernet ports on muxponder transponders are typically clear channel and you still need a switch or router to do your traffic engineering and routing etc. Its mainly a transport multiplexing purpose as how we have deployed them since 1990 hah.
Hi Anne so for RSVP-TE the FRR is only configured in the LSR's?
For FRR, the P routers need to have a facility bypass profile configured on their interfaces that will support FRR. Then the PE router will signal the tunnel with a request for FRR support. Then the P routers know they need to fix the connection if they become the point of local repair.
Thank you, Barbara. Great Video!
Thank you!
Interesting topic, I have had little experience with dwdm, mostly wdm, cwdm, for access we usually use gpon or gepon.
Thanks for sharing that. With coherent plugs and more fiber in place, the optical network is extending its reach and it does raise interesting network architecture questions.
As an old telecom guy, going back to the analog days, I found your comments about going hop to hop to hop to cover a long distance curious. Even half a century ago, when I got started in the business, there would be trunks carrying the traffic between distant locations, without being broken down at each hop. These days, there could be some fibres used for short hops, but also others that are essentially passed all the way between distant points, without passing through routers routers along the way. And yes, they worry about power levels, as they did even back in the analog days, where too strong a signal could result in distortion and intermod between circuits. Even the test tone levels were reduced, when testing over analog microwave links, for that reason. BTW, there is also Coarse Wavelength Division Multiplex (CWDM) often used over short distances, where perhaps a dozen wavelengths are used over a fibre and the appropriate SPF modules are used for the wavelength. These could plug into any standard router that can accept SPFs. In this situation, the multi-wavelength would connect to a diffraction grating filter, which splits out the various wavelengths and then connects to the individual devices.
Because coherent optics can be plugged directly into routers, this video was more about whether using routers was sufficient or if it makes sense to retain an underlying ROADM network. I think it makes more sense to use an underlying ROADM network to continue to make use of router bypass - especially since there is more traffic that is being backhauled to the POPs and handed off. The "hop by hop" referred to pushing all traffic through the routers, which does not make as much sense to me in most instances. I appreciate your comments on the video.
Hi Barbara, Can you explain why P5 is considered in the Q-space as it is not on the post computed shortest path.
Hi Matthew - In this example, P5 is in the Q-space because it's shortest path from P5 to P9 never traverses the potential broken link between P4 and P5. For the post computed shortest path, it is looking for a node that is in the P space and the Q space. P5 doesn't fit into that category and so it's not on the post computed path.
Confusing
Sorry about that
Concise and helpful :) Thank you very much :)
Glad it was helpful! Thanks!
i invented this...
I believe, or at least the way it's illustrated on mine, you want the choke to the left.
Thank you very much.
Very short and highly informative video, now I understood the basics well. Thanks a lot @BarbaraAnne.
Thanks! I’m trying to create videos to help people think about the topic before they go on to investigate further.
excellent
Got cut off at the end?
Excellent and very detailed explanation. I was struggling getting the P and Q knows. Now I have a better understanding. Also, a great point was how to the P4 router calculates what label to push, whether the prefix sid or a adj sid label.
Thank you!
