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. Each of these use cases has some challenges.

All of these messages derive from the assumption that one subnet = one security zone, and therefore intra-subnet communications are not secured. 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.
