- - **Service density 2n-skx tests**: Added higher NF density tests with two
- NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
- used as a VNF payload similar to CNF tests.
+ - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
+ service density tests focus on measuring total per server throughput at
+ varied NFV service *packing* densities with vswitch providing host
+ dataplane. The goal is to compare and contrast performance of a shared
+ vswitch for different network topologies and virtualization technologies,
+ and their impact on vswitch performance and efficiency in a range of NFV
+ service configurations.
