PSNC network in Openstack environment is powered by Open vSwitch (OVS) and Open Virtual Network (OVN), offering scalable and flexible software-defined networking (SDN). OVS acts as a virtual switch, managing traffic between virtual machines, while OVN extends this functionality by adding logical networking elements like switches, routers, and security features. In this setup, OVN integrates with OpenStack's Neutron service, translating API calls into OpenFlow rules for OVS. It enables distributed networking, handling features like security groups, floating IPs, and load balancing. The distributed routing and switching architecture improves scalability and reduces latency. The distributed routers are configured directly on compute nodes, allowing traffic routing to occur at the node level, further enhancing scalability and reducing latency. For OpenStack users, this means efficient network automation, enhanced security with ACLs, and better performance due to distributed routing across nodes. OVN simplifies network management, making it ideal for large-scale OpenStack deployments with complex networking needs.
