Video Transcription

00:00
So welcome back
00:02
CCD a audio to listen to point to a mere instructor.
00:09
In the previous video, we talked about a hierarchical in that remote owes
00:14
from this video, we will begin to introduce Hierarchical and that were designed.
00:22
Here's in a pre assessment question on organization. Is redesigning a three tier hierarchical network into a collapsed the core?
00:31
What design issue is our primary concern? Personal path practices.
00:37
Hey, service is in the ignition.
00:39
The poor density c feature availability, the resource utilization
00:45
from all those choices that seem so related to the
00:50
question
00:51
only closer
00:54
resource utilization is more credible,
00:57
pretty much more whiter. Concern, right?
01:00
Does he wantto save the cause to, you know, improve the performance? There's all related resource for a chargeable the liner, so the choice will be the resource. Your audition
01:14
in today's topic. Neurological never had his life, huh?
01:19
Garage ical In their design. A traditional hair article Land dislike has three layers.
01:25
Um,
01:26
the court earlier provides the past of transport between distributions reaches within the Enterprise campus
01:34
that this traditionally or provide the policy babies. The connective eating the access layer provides a network group and user access to the network is showed in a right hand side of diagram you can see from their core distribution access holidays. Layout
01:52
is a traditional neurological. Never does I.
01:55
We also talked to tear in the layer within layers from a previous video.
02:02
This is Ah, you know how logical? Typical never did like
02:07
hierarchical. And there were designed corn earlier. Core layers of the networks are high speed assuaging backbone that is crucial to corporate communications.
02:15
It is also referred to as the backbone the courtly or should I have? The following character speaks fast Transport high reliability,
02:23
redundancy for tolerance, Law agency in a good marriage ability, avoidance of the CPO intensive packet of manipulation, costs by security inspection, quality of service, Kyul ***
02:38
classification or other processes. Limited a consistent diameter qs
02:46
disillusion layer. The networks of decision layer is the escalation plane between the never exact as in the core layers, the decision early or you can have a manager rules, including implementing the following functions. Policy based the connectivity, for example, in ensuring that
03:01
traffic ascent from a particular network is a forward ate out.
03:06
Why interface? Well, other traffic is a forwarding out. Another interviews
03:13
redundancy and low balancing aggregation of a lion wearing costs. It's aggregation of one connections. Cuba. Alas, security. Few during address or area aggregation or summer audition department. Toller, workgroup access, broadcast or motive past domain definition.
03:32
Rotting part between virtual lands. Venus media translations, for example, between Ethernet and a token of green redistribution between rotting domains, for example, between two different deriding protocols.
03:46
Demarcation between static and dynamic and rotting particles.
03:50
You can use the several system highrises off to our features to implement policy at a distribution. Will you're through touring by source or destination Address filtering on input or output ports. Hiding internal network members by rock tutoring, static routing quality, Kyul *** and McCann ISMs,
04:10
such as priority based crewing
04:14
axes layer the accident. Lear provides the user access. The local second ends on that work. The Axis earlier is characterized by switch the land. Second dance in a temper See environment
04:26
maker Segmentation Using lance witches provides a high bandwith workgroups by reducing the number of the device is on the third night segments.
04:33
Functions of the axes layer included Napoleon later to switching high availability, poor security, broadcast suppression, Qs, concert occassion and marking in the trust batteries Re limiting policing. Address resolution protocol art inspection Virtual
04:51
access. Control us to the A C. L Spend two trusts.
04:56
Classification her overeater Nate and auxiliary villians for VoIP network access Control Neck Auxiliary. A villain
05:05
Learning tak Question number one Which two statements are two regarding a hierarchical never never could choose to
05:13
a provides better performance as that resources are efficiently utilized. Be for some of these choosing the type of rotting protocols to be used in a network C complicates manageability because of the added security.
05:30
The provides scale ability without affecting other layers on a functionality, he limits redundancy out of the distribution layer.
05:42
Um, yes.
05:43
Choose two of the best answers.
05:46
All the high rajput hurt This line purposes tiu no cost the saving and also improving this capability. Right?
05:57
Better performance on the scale ability, right. That's a nd be choosing the type of, you know, this is not a related depend on the hierarchical de lying about what type of a rotting particle you choose.
06:11
See? No, right, because we don't want to complicate manageability, right?
06:17
The e We also don't want, you know, limits re tendency, modernity Dennis. He had this traditionally,
06:25
So the choice again. I'll be a and the thief.
06:31
Question number two Which three layers comprises the traditional hair Ajinomoto. A core earlier. Be distribution later. See access. Layer the
06:43
aggregation layer e not repair half Internet layer. Wait disgust is up. Previously, there are three hour years 40 or distribution earlier on Access Layer is the traditional Rajpal model, right? A BSC
07:01
in today's brief lecture with this guy's the Heretical Now were designed.
07:06
Any questions? Feel free to send the email. I'll see you in the next video bye for now.
