OK, so in this lecture, we are going to talk about multilayer switch and load balancer.
So this is a multilayer switch.
You can see on the screen it has multiple layers, a multilayered switch.
MLS is a computer networking device that switches on open systems, interconnection that is always add
layers layer to it is the datalink clear.
It is like an orderly network switch, but it provides the routing.
A 24 port multiclass, which gives you the best of both worlds, it operates a clear three while providing
for collision domains which a router could not do 24 collision domains, which which means 24 different
ports and 24 different domains so that there can be minimal or less collision avoidance.
Now, the major difference between the packet switching operation of router and that of a layer three
or multiple layers, which lies in the physical implementation.
Intruder's Packards, which takes place using a microprocessor, whereas Laertes, which handles this
by using application specific integrated circuit that is ASIC hardware on the screen is a picture of
three, which you can see that they look like a layer two switches, but they're multi layers.
And the major difference lies in the hardware inside of the multilayer switch and the operating system.
Now, what is a load balancer from the name you can guess that this device might be reducing the load?
Well, you are right.
Your average doctor just sends incoming packets to the specified correlative IP addresses on the network.
But a load balancer can actually send the incoming packets to multiple machines hidden behind one IP
address.
Cool, right?
I mean, it really reduces the load.
Today's load balancing the filters follow various rules to determine specifically how they will route
network traffic.
Depending upon your needs, you can set rules based on the least law, fault tolerance, fastest response
time, or you can end up just dividing outbound requests for smooth network operation.
Think about the scenario.
OK, so you have a website where people are placing orders for the stuff you have got for sale.
Obviously the orders placed vary in size and the rate at which they come in also varies.
You definitely wouldn't want your servers becoming so overloaded that they rose up and crashed your
site, causing you to lose a lot of money.
Now, what would you do?
That's where the load balancing of the traffic comes into picture, because even if one of the service
freezes, your customers will still be able to access your site and place orders.
That is why in today's world, sites like Google, Amazon, Apple and IBM, there are a whole lot of
examples which actually use lower balances because they have a lot of visitors coming from all over
the globe.
Just imagine Amazon, how it might be handling the requests that are coming throughout the globe.
Right.
With the help of load balancer.
You got it right.
In the next lecture, we are going to talk about the DNS server, which is one of the most important
topics in computer networking.
