- 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 other modern networking benefits, you know
examples of these open source initiatives include things
like neutron from open stack, the open B switch
or OvS the open virtual network or OVN
the open daylight 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 really know, the concept of SDN is very broad
and every open source provider and commercial vendors
that actually takes a little bit different direction.
For example, the networking component
of OpenStack is called Neutron
and Neutron is designed to provide networking as a service.
And basically they can be used
in private, public, and hybrid cloud environments.
Now, other open stack components like Horizon
which is actually the web UI or Nova, which is
the 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 the 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 Open Stack
or Neutron, but you can actually obtain more information
about Neutron and Open Stack at the link that I'm sharing
on the screen.
Now OVN was originally created by the folks
behind open V switch 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 V Switch is actually an open source implementation
of a multilayer virtual switch inside of a hypervisor.
Now you can actually download Open V Switch and, you know
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 open daylight project or ODL.
Now for the exam, you only need to have some high level
familiarity with, you know, these open source components
and examples of them and the concept of SDN.
But if you actually want to find more information
about open daylight and you know, of course, you know
the underlying technologies, you can go to open daylight.org
as I'm showing on the screen.
And also Cisco has several tutorials
and additional information about open daylight indefinite
and you can actually obtain more information
at the link that I'm showing in my screen.
