Last week I had the opportunity to join John Troyer on the VMware Communities podcast. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February. Or virtualized firewalls?

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.

These protections are also expensive to implement in hardware. This bypasses some IPv6 limitations because host routes are treated in hardware like ND cache entries (which means you get something like 32K entries). VMware NSX has a stateful IPv6 firewall that provides RA guard and ND inspection services.
