VMware NFV Footprint



bution

• No! Porting proprietary solutions onto a hypervisor does not solve the old problems

– Moving from closed HW solutions to a hypervisor on COTS HW is only a small step toward NFV

– Need for a “Cloud-Native” approach to VNF design from ground up

• Introducing a new service and provisioning resources remain too cumbersome

– Instead of connecting & configuring hardware boxes, we now configure VMs

– A bit faster with reduced professional services, but still a time consuming, tedious process

• Auto-scaling infrastructure is only partially here and in a limited way

– A programmable approach to auto-scaling? (see later example)

– SON-like capabilities in software network controllers?


So, “Are We There Yet” As a Community & Mature Technology?

VMware Poised to Lead the IoT/5G “4th Industrial Revolution”: Hierarchical Dynamic Service Networks

• SDN is at its infancy – Network Virtualization vs Server Virtualization

– Server (network node) virtualization is a requirement

– Innovating in the next-generation virtualized networks: Dynamic Service Networks

• NFV – first manifestation of true wide-are Network Virtualization

– VMware Network Virtualization: Network slicing and DSNs

– VMware NFVi provides the end-to-end, differentiated v-infrastructure for 5G readiness

– Cloudets for Mobile Edge Computing

• Hierarchical Network Slicing and the concept of Dynamic Service Networks (DSN)

– Network slicing is one of the most challenging problems – but a necessity for IoT

– Investing in carrier-centric technologies and solutions for IoT verticals

The Conundrum: Competing in the 21st century with robust 20th century infrastructure and processes



bution

• A (logically) central VNF Registry maintains a registry entry for each enabled VNF

– VNF manifest, NFVi manifest, APIs supported, interoperability configuration attributes etc

• Extensions (annotations?) can enable auto-generation of VNF and NFVi manifests

• Marketplace of APIs and format converters can generalize the applicability of model

• A binding process generates the micro-orchestration actions needed to enable the new VNF

• Micro-orchestrator implements configuration set up and brings up the new (VNF) service
