- [Instructor] Let's go over several open source projects
and components that are trying
to provide micro-segmentation
and also SDN capabilities, right?
So starting with micro-segmentation,
and another modern networking benefits.
Examples of these open source initiatives include things
like Neutron from OpenStack,
the Open vSwitch or OvS,
the Open Virtual Network or OVN,
the OpenDaylight Project or ODL,
and the Open Platform
for Network Function Visualization or OPNFV.
Now, Cisco also has a solution called Contiv
that also provides these type of capabilities.
Now, as you already know,
the concept of SDN is very broad
and every open source provider
and commercial vendors,
they actually takes a little bit different direction.
For example, the networking component of OpenStack
is called Neutron and Neutron is assigned
to provide networking as a service
and basically, they can be used in private,
public and hybrid cloud environments.
Now, other OpenStack components,
like Horizon, which is actually the web UI
or Nova, which is a compute service,
they interact with Neutron
using a set of APIs to configure the networking services.
Neutron actually uses plugins
to deliver advanced networking capabilities
and allow third-party vendors
to integrate with their solution.
Basically, Neutron has two main components.
The Neutron server and a database
that actually handles the persistent storage
and the plugins to provide additional services.
Now, this is of course, not a class
about OpenStack or Neutron
but you can actually obtain more information
about Neutron and OpenStack
at the link that I'm sharing on the screen.
Now, OVN was originally created
by the folks behind Open vSwitch or OVS.
And it was created for the purpose
of actually bringing an open source solutions
for virtual network environments
and SDN environments.
Now, Open vSwitch is actually an open source implementation
of a multi-layered virtual switch
inside of a hypervisor.
Now, you can actually download Open vSwitch
and start playing with it
and access the documentation at openvswitch.org.
Now, another very popular open source project
that is focused on the enhancement of SDN controllers
to basically provide network services
across multiple vendors
is called the OpenDaylight Project or ODL.
Now, for the exam, you only need
to have some high-level familiarity
with these open source components
and examples of them and the concept of SDN
but if you actually want to find more information
about OpenDaylight and of course,
the underlying technologies,
you can go to OpenDaylight.org as I'm showing in the screen
and also Cisco has several tutorials
and additional information about OpenDaylight in DEVNET
and you can actually obtain more information
at the link that I'm showing in my screen.
