Verplanke believes that DPDK (Data Plane Development Kit) and virtualization are key to virtualizing workloads that move around lots and lots of packets, such as firewalls, routers, and other similar functions. Devices first started as tightly-coupled hardware and software solutions. First, DPDK provides optimized pass-through support.

It streamlines server deployments because you can now deploy servers based on templates with almost no regard to the underlying hardware. These virtual ports can then be assigned to a virtualized Firewall, Switch, Router or IDS ports based on the need. Cisco has a similar device level approach with their ISR architecture.

These protections are also expensive to implement in hardware. For Carrier Ethernet, Cisco ME3600—a very expensive switch—will allow you to implement such an architecture. This bypasses some IPv6 limitations because host routes are treated in hardware like ND cache entries (which means you get something like 32K entries).

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware.
