Welcome back to part three of this video series where we will look
at hardware and software architecture.
Juniper likes to keep journals consistent across all their platforms
which is a pleasant change from some other vendors.
In this brief video, we'll see some of the platforms that Juniper are using.
Back in 1998, Juniper released their first on the M40.
The M-series was aimed at high end customers and service providers.
This was the old traditional router which has been end of life
for over a decade now and had no switching features built in.
After that, the T series was released as an even more powerful router
These were high speed routers used in the core of service provider networks.
These are also getting on in years and are no longer manufactured.
They're still supported though.
So you might find them out there in the wild.
Over time, Juniper needed
to diversify and extend out of the high end market only.
So they created the J-series router for small enterprises and branch offices.
These are end of life and out of support,
but you might still see some in production.
Okay, let's get out of the history books and into the current range.
Their flagship is the next series router.
The first generation of DS was released in 2006
and is aimed at the edge of the enterprise network.
Unlike traditional route is, these routers support both routing and switching.
The second generation of mixed routers is called Amex
3D and is based on the trio chipset.
3D refers to the three core features
bandwidth scale, subscriber scale and service scale.
There are several physical models available as well as the virtual VM X Appliance
their AC
X-series, Reality's Fanless and sealed, making it environmentally hardened.
This makes them suitable
for metro ethernet, outdoor cabinets and that kind of thing.
They range from small to large routers
and finally the PTA or packet transport router.
These are their high speed routers used in service provider
core networks.
One of the most well-known devices
in the Juniper Range is the Citrix Firewall.
This is both a firewall and a branch router.
As a firewall, it's somewhat comparable to Cisco's a firewall.
As a router.
It's comparable to Cisco's ISR series.
There are several physical devices available
as well as a voice or virtual appliance.
Let's look at the switching portfolio.
The series is aimed at the campus
and designed around the core distribution access model.
These are comparable to Cisco's Catalyst series.
They range from low end
switches with basic features like the one we configured in last video.
Two high end core routers.
The low end switches are very affordable.
Then there's the Q series of switches, which are mainly used in the data center.
These are very low latency switches
designed around the spine leaf deployment model.
These are roughly comparable to Cisco's nexus switches.
If you haven't noticed yet, Juniper love putting an X into all of their products.
I have no idea why, but if you can figure it out
let me know in the comments.
There's just a couple of more Juniper products to be aware of
before we finish up this video.
I'm going to be brief, but you can look into them deeper if you want to.
First up is junior space.
This is a central management system for managing your Junos devices.
This can push configs, switch updates, report on uptime and so on.
If you're managing a lot
of switches, routers and firewalls, take a look at junior space
Next is NEF X,
which is Juniper's SD end devices.
You can send an end effects to a branch office and provision it remotely.
And if this goes long with control, which is the SD and controller,
this is where the SD and policies are defined
in a somewhat similar fashion to Cisco's HCI.
And finally, Northstar, which is the win controller.
If you're not sure where to start, look at the X and Citrix platforms.
First they're affordable and there's plenty of information
about them out there.
Let's get more interesting.
