Class Notes
What is Convergence?
Different types of computerized systems used to be "siloed" in their own environments. They used different types of cable and protocols for communications.
Convergence allows different types of devices to use standard computer networking components and protocols
By using Convergence different types of systems can now talk to each other
Power Over Ethernet provides power for devices over Cat5 cable
Either the Switch or a Power Over Ethernet Injector is used to provide power
Quality of Service allows you to prioritize the importance of network traffic
Parallel Networks are used when you are concerned one type of network equipment will degrade the performance of other equipment. An example is putting VoIP on it's own LAN to prevent file traffic from causing jitter.
Engineers are trying to make devices more intelligent so that less data is put on the network. By making devices more intelligent less communication has to occur with main servers.
"And like I say..." you are a great teacher who maintains an easy-to-understand method to all his lessons. Thank you!
Thanks for this, Eli! I'm in a cisco class and I like how you explain these things in a way that make sense. Keep up the good work! You're a rock star!
Holy shit, Eli. 26:06 had me in stitches. I'm watching at 1.5X speed btw.
🤣🤣🤣🤣
This video ages 10 years ago, but my lecturer still uses this. This indicates the quality of the video.
Eli you're the greatest!!!!! I know so many Quote IT Guys Un-Quote That can't never tell me (I'll say -- due to public viewing) anything worth a grain of salt! You know what I mean, You have helped me so much. Please post a link so I can make a donation and THANK YOOOOOU!
Thank you so much! This has really helped me understand the concept for my networking class. Bless up homie!
Eli you're the best. You're a treasure trove of knowledge.
Thanks alot sir.....u know how to break the walls of confusion down. much appreciated. God bless you
please make some videos about CCNA contents,i really like the way that you teach us,it s very easy to understand,thank you
The imitation of a laggy telephone conversation was quite convincing ;D I must say
I have to run Eli's video at 1.5 speed. He talks too slow to make us understand but now i am very comfortable with his voice so speeding up all that stuff so i don't get bored :)
Abhimanyu Aryan 2x works well too
Dude, nice lesson.
Thanks for explaining this convergence topic, in good detail.
Because it really helped me understand, what convergence is.
Excellent teaching, you make it so easy to understand, thank you.
Love all your great videos. more, more, more.
There's plenty of content there and even online courses but you have to sign up for their Academy, which isn't free I believe. There's also a ton of CCNA and CCENT videos on youtube. Most important thing is you'll have to buy some gear like couple of routers and switches to practice on, unless you have access to those at work or something.
Love your videos (Sorry for my bad Eng) All explain in one simple way no bullsh..s. Sad for the latest happend's (TH-cam), but carry one, d'ont give up, you have lot to teach (and you're good (BTT) (Born to teach))), grettings from France.
I want to be your student, you perfectly know how to teach people IT technology ... I work in Georgia, by the Interior Ministry in the IT technician. Can I come with you, and I pass the training courses?
@jgrabener As they say... "it depends"... If you have a router that connects the two VLANs then you can, if not then you can't...
The first and last parts of your video audio sync problem. Other than that, it's great.
Eli,if you put all your device on parallel networks that means each network have its own traffic and own bandwidth? if that's the case you shouldn't worry about QoS and traffic on the network, right?
what switches provide power? Is the tech standard? Compatibility issues?
Imagine playing Pictionary with him... :) Just kiddin', great channel, great lessons!
Will you be doing any Intermediate or advanced Networking videos?
OK so convergence at first was introduced to reduce cabling by connecting to one switch but then parallel networking was introduced so that they don't get overlapped and different switched were put up in network for every different line of devices. So ULTIMATELY, we again have to use different CAT wires (which ultimately increase cabling) to connect to different switches. What we are actually trying do here?
Confused a bit and need help!
Thanks in advance!
Basically we are trying to eliminate the need for specific hardware and cables for certain applications. You used to have to have different kinds of cables for things like cameras and telephones to communicate data across them. Through convergence, we are only using one type of hardware protocol to take care of these services (Ethernet, routers, switches etc.).
But sir we already allocate the bandwidth to each user.... so is it still possible that a user dominates over the allocated bandwidth of the other user????
Sorry Eli if this is a silly question, but I am new to networking and I haven't heard this before, but how do you spell silos or siloads, you were talking about it in the 6th minute.
silo: en.wikipedia.org/wiki/Silo
abc140290 thanks!!!
seems like the audio isnt synced with the video..
Network latency :_)
Okay. Cabling is single now. But, two differnet devices can't connect to single wire. Then how is it working?
God bless you.
Eli can u make a couple of videos on (1) network topologies & (2) network troubleshooting ? :)
sorry,i couldnt find them on cisco website,if you know the link can you share it with me ? thank you
Pls make video on Hyper converge Infrastructure
Thanks Eli
thank you
You are good
thank you so much u r the best
I didn't understand exactly how parallel network works anyone can please explain me
+Vishal Kamble It's basically re-siloing the systems similarly to the way they worked before convergence where they were all separate from each other.
+Richard Craig thanks for helping me to clear that topic
100%
Well sounds good and inspiring and GUIINGLY great you know , BUTTTT
well centralizing everything to a matrix source, is arguably not the greatest thing in the world, in my humble opinion.
Is like everything is has its UPS and DOWNS
you shoud get a full image of your board
NO phone call is more important than an Angelina Jolie movie.
Check out The Venus Project, i know it might sound a little bit like a spam but it worth looking for a better world, a better tomorrow for ALL the world's people!!!

26:06 - LOLOLOLOL
comment.
👀 in 2022🚀🚀
go to CISCO web :P
one of my problem in pfsense how to allocate the data.
Watch 26:05 at 0,25x speed
lol
Eli, seriously! You talk in so many network circles I got dizzy and threw up, twice, because I couldn't shut you off fast enough. So we split very thing up on parallel networks after spending $$$$ to connect it all together? What does that cost? 3x$$$ Any expense installing proprietary cabling far outweighs troubleshooting multiple layers of Ethernet switch issues. You obviously were a trunk slamming integrator. Most proprietary systems have a network link that allows all the nice interoperation features you mention. So why contribute to the network sprawl? Just more infrastructure to maintain and added security frailities.
Sheesh, voice and video aren't in sync today ... Sorry, Eli, have to hide your face and read the CC. Makes me crazy otherwise.
Dang, the CC and transcript suck too. OK, just listening this time.
26:05 😂
5 pixels high-deaf.. lol
+jose cruz I said the same thing, then looked at upload date and was like "oh..."

From a networking perspective convergence occurs when a protocol is at rest or in a normal state and not in an active state. This explanation from this video is not accurate.
