Network Virtualization makes most modern Path Isolation techniques in networking possible. Network Virtualization and Path Isolation are crucial in modern network design and implementation.

Quick tip: Virtualization is VRF in the router, VLAN in the switch, trunk (dot1q tagging) on the Ethernet link, context or VDOM on the firewall and VM on the server.

Network Virtualization

This was good enough reason for creating a blog post series which is giving an organized overview of different approaches in implementation of separated logical network partitions which are implemented over the enterprise physical network.
