This version of the vCloud NFV platform supports accelerated data plane. Both control and user plane workloads can take advantage of this capability and achieve higher throughput, reduced latency, and scale in performance.
Scope VNF components that require high network throughput can achieve high data plane performance by using the advanced switching fabric that is introduced with the N-VDS logical switch of NSX-T Data Center and by using the Edge cluster acceleration in the Three-Pod configuration.
Design Objectives The vCloud NFV platform includes NSX-T Data Center as the virtualized networking component. NSX-T Data Center leverages key DPDK features, such as Poll Mode Driver, Flow Cache, and optimized packet copy, and provides better performance for both small and large packet sizes that are applicable to data plane intensive VNFs requirements. The NSX-T Data Center networking stack increases the CPU efficiency while preserving the existing functionality of the VMware NFV infrastructure. The accelerated switching and enhanced platform deliver advanced networking architecture that is transparent to VNFs, providers kernel-based security, deterministic resource allocation, and linear scalability.
