Can you hear me?
Yes.
Okay.
So, I would like to start with the simple question.
If you guys know what's buffer bolt.
If you ever heard about buffer bolt and things like that,
like latency and jitter, that this is the right room for you.
And even if you're not, I would like to change that.
So, is it any better or okay?
Yeah.
So, buffer bolt, it was supposed to be changed.
The world was supposed to be good for now,
because the solutions for buffer bolt, latency and jitter are well-nobbing.
The problem is that vendors, ISPs, and even as as customers,
we still didn't accept it like all the good and free stuff that are out there.
And therefore, we are also offering.
So, you know about things like code, FQ, code, and cake, right?
There are new things like doxy, spy, and L4S,
right by Comcast, for example, in the US.
It will be tried by Deutsche Telekom in Germany,
and also by Vodafone in the UK.
Vodafone trial is, if I remember correctly, ongoing.
We don't think that these things will really solve the problem.
And therefore, there is a reberky OS as a force multiplier
or internal service provider.
And though I was mild, you as a people at home,
you can fix your Wi-Fi, you can fix your last mile,
but the ISP needs to done the heavy lifting.
They need to do a lot of things in order to fix the OS mile,
and they have a middle mile, and that's the question of peering and cdns.
So, SQM is very hard for you as a customer,
because you can fix your Wi-Fi, but then there is a last mile,
and it's really a CPU-intensive kind of thing.
But if you are aware of waveform, buffer ball test,
so these are the typical, really good results
that we will try to achieve for an ISP and their customers,
when they are using Vodafone OS.
Or there are other co-source quality of experience,
middle boxes out there.
For example, there is a market leader called Pricine,
which is a Canadian company.
Like former, send-wine people, send-wine those big boxes for telcos.
So, they created pre-seem, like seven, eight years ago.
Then there is a backwant, which is Spanish company.
They have a really good penetration in Latin America,
and Spanish speaking markets in general.
Then there is Paracun, which is Paracun technologies,
and that's a company from Sri Lanka.
And they have also really good penetration in the world.
And there is some wine, those big boxes for big guys.
And also there is a Cambium network, like former Motorola canopies,
if you know them.
And they have also a quality of experience, middle box,
but again it's called source, and they are using backwants engine.
So, the thing that is really different with us
is that we really try to get the network topology of an ISP,
and we want to model all the hopes.
So, typically, other solutions think that there is an ISP,
and there is a customer.
Or maybe there is a one-tab or one hope between the customers.
But, you know, networks of the ISPs are really complex.
So, we can model up to nine hopes for,
so you might have a cover, pop, micropop,
and this kind of configurations.
And also, this looks really nice on a really big screen,
for an ISP and NLC.
So, their network people can really monitor what's happening in their networks.
They can see all the falls.
So, when there is a problem, they will see a rat, right?
They can jump in and drill down to the particular problem
that's happening in the network.
So, this is clickable.
So, you can go down to the access point level.
So, Linux traffic control is really good,
but it's a single-traded.
We need to do something else, right?
So, we were utilizing HDB and cake.
The other thing that's really good for us,
and we also contributed to the upstream is,
it's an XDP CPU map.
Yeah, let's go back.
Okay.
So, Libracus is currently at the point of 1.5
beta 8, and we are preparing the big updates to 2.0,
and it has a lot of new features.
Even though there is just four people doing all this stuff,
the other companies are really big.
They have dozens or in the situation of Cambium,
hundreds of people.
And, you know, I don't even code.
So, all the heavy lifting is done by three people in the company.
The other thing that we are really trying to show to the ISPs,
and later on probably even for you as a customer.
So, ISP would be able to show different screens from Libracus
to you as a customer in your customer portal.
So, you will be able to see what's actually happening.
So, if the ISP claim that there is a network outage,
they would be able to prove to you that there is a really a problem,
and there is no shenanigans or something else.
So, we would like to have it more customer and customer centric.
So, let me...
Oops.
I won't be able to...
I'm sorry.
So, this was supposed to show the traffic of the...
an latency of typical customer of hours,
but, yeah, it's in cloud, so, I'm sorry.
Anyway, so, when you are running your typical internet connection at home,
for the most of the things that you might be doing,
like downloading a game, or things like that,
or uploading a game, or any other big file,
you don't need to have anything that will help
video or latency, buffer volume and jitter,
but for interactive stuff, which is, for example,
even like, opening of a website, right?
It's not about bandwidth, it's about latency in the end.
So, you hit the enter, and till the page is fully loaded,
and you're able to interact with your page, it's about latency.
So, for those like two critical percent of everything that you do,
the latency is the most sensitive component of the experience that you are getting.
So, at the beginning of COVID, so many ISPs,
as well as so many of us, they were forced to stay home.
We had a problem.
So, that was the, like, mad dash for many ISPs,
to find a quick fix to all the latency,
buffer volume related problems that they had,
and one of one of these solutions that were emerging at the time,
was LibricUS.
One of the things that we, what we decided to do was,
to get the TCP retransmit,
because there are, like, really important kind of thing.
And also, like, for ISPs, it's really important to see
a particular sector.
So, we can imagine the one access point on the cover,
to which you as a customer is connected.
And for an ISPs to really use the resources,
to really utilize the bandwidth,
they are still forced to over-subscribe,
which means that, for example, you might have, like,
1,000 people utilizing one gigabit.
And ISPs might be selling you 500 megabit package,
and you're, you're wondering, you know,
how it's that possible that they can,
they can do it with one gigabit,
but one of the factors that's helping with the steep,
crazy oversubscription,
which is still manageable, and you don't suffer, you know.
It's a quality of experience, middle books.
So, it can be done on the access point level
for, for, for, for, for an ISP,
and it really helps them to utilize the bandwidth well.
Other thing that we are looking at are ISPs, right?
So, for US and ISPs,
it's a really important information, you know,
where the traffic is going.
So, this, like, a simple glance of an ISP,
to, to, to page like that,
it can tell him that, you know,
if, if there is a chance, for example,
to, to connect directly to CDN,
and most of the,
its customers are getting stuff from this particular CDN,
they should try to connect, right?
Or they should realize that they need to be a more.
So, Robert,
that's our colleague from West Texas,
and he, he was the guy that started
the whole thing at the beginning of COVID,
and he,
put together a simple Python script with FQ Corel
and put it on GitHub,
and it started to be used by many ISPs in the world.
And so, he said that he must be up to something.
One of these ISPs that, or, yeah,
former ISP,
but the guy that created FQ Corel and K,
with many other, many other good people,
sold it,
and he realized that this is a really good thing,
and he decided to join in, Robert, and help him.
Dave told about it to,
to other, another colleague,
which is a really well-known,
RASCRO grammar, Herbert,
and he decided to join,
and rewrite the whole,
the whole,
Libric US to RASC,
because RASC,
believe it or not,
is one of the most efficient,
and safe,
and stable languages that we can use.
And Dave told about Libric US to me as well.
Prior, Libric US,
I was working with antennas for Internet service providers,
so that was the company,
and it opened WRT routers.
But I was looking for something else,
and I saw that as a force multiplier to the world,
to basically finally solve the latency.
So, we are really small team,
but we keep adding new features.
We are really working a lot.
So, we have NetFull, NetFull,
IZIS.
If you have a question in mind,
how we integrate with ISP.
We are integrating with CRMs or NMS solutions.
So, there are Splings,
that's really well-known.
No one company in this world,
S.P. is a free product from Ubiquity Networks.
Really, really good one.
They have probably the best mapping for
NetFull topology of an ISP.
Others are solar and public code.
There is a new guys on the market,
Gaia,
they are from Canada.
Then there is a Whisk Gate.
These people are from Turkey and South Africa.
And there is Whisp,
that's American company.
We are, like I said,
we are adding new features all the time.
And currently,
you can see the numbers of the shape devices.
So, it's a million now.
And it's growing by any ISP that's connected with us.
Right now,
we are in 58 countries and 28 US states.
And the number of the ISP is more than 400,
right now.
And these are only the ISPs that are sharing data with us.
There are many ISPs that decide
it to don't share anything with us.
So, we just don't know.
But they are popping up in our chat.
And they are reporting potential programs
or feature requests,
or they want to thank us.
So,
liberty was free and open source,
and it will be forever.
But everybody else,
we need to eat.
And therefore,
no one that is helping us to eat some stuff.
Besides anything else,
we want to really take them.
There is another co-sourced company that's helping us.
And that's equinex.
They were giving us some bare metal stuff.
So, we were able to build test best
and do things like that.
So, yeah,
for you,
you don't know the particular brand of ramen that you like.
So, that's really famous.
We like to eat the ramen,
but we would like to eat some vegetable and states as well.
So, we are trying to figure out how to do that.
We don't know that.
This is not the end.
I have more slides,
but I have three books,
about buffer bolt.
I have to give it to you guys.
I have also stickers.
So,
I hope that you will come over and get some of them.
And let's continue.
So, take the picture.
So, you can order your own book for free
from University in Karastad.
And you can also find the PDF and download it if you prefer.
And this is the most comprehensive book
that was ever written on the LibraQS.
It was also a PhD thesis of Tokyo Highland, Yorgensen.
And there was many, many great people like Dave Tair,
Jim Gettys, and many, many other people from the Latency World,
both world, jitter world,
that helped to write this book.
Get your router fixed.
Open WRT.
If you know how to do that,
it's not a hard.
If you don't want to,
you can buy geo-init product.
That's open WRT with some stuff,
but it's really good.
Dave Tair was helping with geo-init to help them.
There is also two resomnia.
I was working with two res in the past.
So, that was the best open WRT router I ever know.
And even right now, after almost 10 years on the market,
it's more powerful than most of the so-called routers you can get.
So, you can have 10 years of router.
You can change V5, V5, V5, V5, V6,
then V5, V7, LT, V5G, and you're good to go.
You don't need to change your router every year.
How the manufacturers would like to see.
Dave, he is co-outer of RFC 80 to 90.
If you never read it, go and read it.
And I use it.
There is FQ Codell, and it's continuation, which is cake.
Herbert, my colleague, is releasing a new book on Rust.
And it's probably his third book already.
And he will be at Rust Nation UK.
If you are by any chance interested in Rust,
and you have time and plays and money and everything,
you feel free to go to Rust Nation UK.
I think that we as an open source world,
we did more Rust besides any other languages
to do our job better, and more efficient, and more safer.
And yeah, that's it.
Thank you very much.
So I have those three books, so please get them.
And I have speakers.
Yeah, so who want to have a book?
There we go.
Stickers.
We have three different colors.
So.
Yeah, I can.
Yeah, hi.
Thanks for your talk.
I run an internet exchange.
I wonder if there is anything I can do to help with an internet exchange.
I'm, I'm, I'm having trouble to hear.
Can you repeat the question?
Please.
Yes.
I run an internet exchange.
And I expand.
Is there anything I can do to help in the buffer bloat?
So you have an ISP?
I expand.
Internet exchange platform.
Like, you know, Amsex or something like that.
Oh, so if this can be used in Ix?
Yeah, exactly.
Okay.
So, not right now, but people are asking for other use cases, right?
So, for example, there is installation in mines.
Like, so it's running the oil latency in mining in Finland.
And there are like universities, like university of Santa Clara.
And they are running it in their campus.
So there are other other use cases already.
And, for example, vessels.
So you might have a boat, and you can run a network with this.
So there are more and more use cases that are coming, not just ISP.
So, yeah, thanks.
Thank you.
Any other questions?
Thank you.
Hi.
