Hello and welcome back. Dicey. And you want interconnecting Cisco networking devices. Part one,
This is Episode 133 Way and Technologies. I am Trenton. Daryl and I will be your instructor for this course in the last video win over Least lines and the HDL see layers to protocol. In this episode, we're gonna be covering some of the various went technologies that are on the ice and the one exam such as E O M P L S D s, L
So, learning objectives for this episode really quickly go over a brief history of the Ethernet standards.
We're gonna learn a little bit about hell, Mpls,
look at D S O. And finally, we're gonna look a cable.
So a quick pre assessment here, what do you guys think is another name for Ethernet emulation
And I'll give you a few second ***. You pause the video here.
All right, Hopefully you guys got same answer.
Should be CEO and pls
It's a quick history of the Internet standard. Originally, Ethan, that was not It could not a viable land technology, because with copper it was only reaching about 100 meters of 300 feet so I could stretch across the campus a little bit, but it couldn't reach much farther.
Then, with the birth of fiber optics with the 1000 base Alex, we could actually reach about two kilometres and then later on we have the 1000 base Z X, which will reach about 70 kilometers. So now these routers can use the Internet interface to connect to the point of presence or the pop
instead of using their cereal in a phrases
so either none emulation again. Like we said, it is the hell mpls or Ethernet over Mpls and Ampule asses the multi protocol label switching I know its acronym Inside of Acronym.
What that does is it provides a point to point connection between two customer devices. So it kind of behaves as if there is a direct fiber Ethernet link between the two devices. So physically they connect to the service's point of presence from the routers. Biologically, they connect to their own devices. So if you look in the
example in the bottom of the host on the left, where to send a frame to the host on the right,
it would go along to the P one router, which would d encapsulate that frame.
Recaps elated with the source address of P one
and then the destination Mac address of Pee too.
And they want to reach his p two. It would d capsule ate that than
encapsulate with the source address of P two and then the destination Mac address of the host on the right,
D s l is the digital subscriber line. So this was used in place of the telephone line. So to utilize the existing wiring that was already there.
So what it did was it should prided kind of a short link to the telcos network. It's only to do is get to the loop extender. So you really needed for this was a. D S O Motome. And then the Toko had have a D slam which separates
voice in any data traffic.
Now, if you were to utilize the
let's a landline phone in a modem on the same wall, Jack, what you're going to use a D S l filter on your end?
Cable, Internet. So what that did it is. It also took advantage of existing cabling, so it used the cable TV cabling
and again that gave you a symmetric speeds, just like D s. L did. So the download rate was usually faster than the upload rate
because usually if you just send the to upload a request to grab a website wasn't watch data, but to download the website
it took a little bit more.
But again, this is the co axial cable. And instead of the telephone line that D S L used
so the cable TV company did, all they have to do is split out the video and data on their side and your side. You need to hook up cable modem,
which is relatively cheap, and these speeds air typically faster. India. So
I know when I was growing up, I had dial up, which was 56 K,
and eventually you know, you couldn't do a whole lot. I could kind of get on your email
and eventually went to de eso. We had shed 5 12 kilobytes, and that was that was a pretty good upgrade.
He'd actually browse the Web easily. There was some video games we could play online,
but downloading large items still took awhile. Then eventually it didn't want to 60 megabits per second.
And remember, video games taking three hours to download instead of days. So so we have a post assessment here.
What devices required him A toco site to separate voice traffic from data traffic with D s. L
give me a few seconds to posit video here.
Okay. Welcome back. Hopefully you got d Slam
the D S o access multiplex. Sir,
In the next lesson, we're gonna be talking about the fundamentals of I p for addressing and routing.
And as always, if you have any questions or you need help with this lesson, police feel free to contact me with any questions you can't figure out.
Thank you for washing this lesson. And I look forward to seeing you in the next one.
