How the Nuage SDN solution works
One of the market-leading SDN solutions is the Nuage SDN (VSP) platform, which is Nokia's SDN solution (formerly Alcatel Lucent), so we will explore how this market-leading SDN solution works.
The Nuage VSP platform comprises three main components—the VSD, VSC, and VRS.
Virtualized Service Directory (VSD): This is the policy engine for the overall platform, and it provides a graphical user interface and exposes a restful API for network engineers to use and interact with network functions.
Virtualized Service Controller (VSC): This is the SDN controller for Nuage, and it uses OpenFlow and OVSDB management protocol to distribute switching and routing information to hypervisors, bare metal servers, or containers.
Virtual Routing and Switching (VRS): This is Nuage's customized version of Open vSwitch, which is installed on compute nodes (hypervisors).
The Nuage VSP can integrate with OpenStack, CloudStack, and VMWare private cloud platforms or public cloud solutions...
