necessary to provide service and of their interdependence on the
hardware;
– the physical devices necessary for CISCO’s ACI architecture:
they belong to the CISCO Nexus range. Cisco Nexus 9000 machines
function either in Cisco NX-OS mode for purposes of compatibility
and consistency with the older Cisco Nexus switches, or in Cisco ACI
mode so as to take full advantage of the application services based on
the policies and functions of infrastructure automation.
2.12. OpenContrail and Juniper
In 2014, Juniper also released its own SDN architecture, essentially
based on open-source software, but with Juniper’s own addition. The
heart of this architecture is the OpenContrail controller.
OpenContrail from Juniper is an open, simple and agile SDN
solution which is able to automate and orchestrate the creation of
virtual networks on demand. Virtual networks are perfectly well suited
for applications which require networks to be opened. In this
architecture, we can emphasize its simplicity for the establishment of
virtual networks which integrate smoothly with the existing physical
networks, and are simple to manage and orchestrate. The environment
is also open. There is no dependence on one particular provider. In
addition, this open architecture eliminates the costs related to device
manufacturers. The Juniper platform works with a broad range of
open hypervisors, orchestrators and physical networks. Finally, an
enormous advantage is the agility of the solution, which reduces the
time to market of new services by automating the creation of software
networks, facilitating the interconnection of private, public and hybrid
clouds.
Service providers can use Contrail to offer a whole range of new
and innovative services – particularly Cloud-based and virtualized
services. The Juniper platform is shown in Figure 2.22. It should be
noted that, as this figure shows, the platform tends to use Open Stack
more than anything else, but this is not obligatory; other Cloud
management programs are also acceptable.
