Hi and welcome to Cyber. My name's Anthony and I'm your local subject matter expert here for Network Plus And today we're gonna be identifying virtual network components. So what are virtual networking components? Well, virtual computers, just like physical computers, need a way to communicate with each other. They need a way to communicate out on our network.
00:22
And a lot of times we need to include virtual network components in order to allow them to do this.
00:27
Now our virtual computers may have the benefit of being all on one server, but this may give us the downside of that server may only have one network interface card. Now our network interface card is going to be the way that our computers talk out. It's gonna be the way that our virtual servers or virtual PCs talk out on our network. So
00:47
rather than installing multiple network interface cards, which we may decide to do anyway for a better load balancing and better performance, we may need to install virtual network Compliance is now what are these? Virtual network compliance is well, these virtual. These virtual network appliances help us to eliminate unnecessary physical devices such as
01:06
physical switches or physical
01:07
PBX is which allow us tohave phone connections. So we may just take these devices and we may virtualized them.
01:15
Now. These virtual network devices allow us to do things such as set up V lands between our different virtual servers. So rather than having a physical server with multiple virtual devices inside of it,
01:29
so we'll say, four virtual for virtual servers inside of our single server rather than them all having to be on the same i p sub net rather than having to say have the same i p address.
01:44
We could have
01:46
different virtual devices
01:49
on different I p address ranges so 1 90 throughout 1 68.1 dot to 1 92.1 68 dot to 68.0.1. And this
02:00
server, this physical server only has one network interface card. Rather than having to install multiple network interface cards for these votes for our multiple different networks, we could instead
02:13
have a virtual switch, which allows
02:15
villain connections between
02:20
these multiple devices
02:22
and then talk out through a trunk line
02:24
through our network interface card. This is just the tip of the iceberg, with all of our different virtual devices. There's a lot Maur that virtual izing our network virtual izing our servers virtual izing our workstations could do for us. So let's go ahead and take a look at our different devices and see how they work.
