Remote Offices and Enterprise Branches come in all shapes and sizes, but something as profound to an industry as Network Function Virtualization (NFV) faces an uphill battle from suppliers and customers, that's having a major impact on the customer to vendor relationships. 


Along with system integration designs, special care has to be taken in software evolution to improve on CPE solutions. Service Providers offering a High-speed, multi-tenant network service come with a wide variety of requirements, high-performance service chaining is a no-brainer.  


Ciena is bringing thought leadership for the consumer, business services and mobility transformations regarding multi-vendor virtual network function (VNF) designs, platform resource rationing, service-chaining with BluePlanet orchestration integration, automating provisioning and service lifecycle management. Offering highly flexible services and real-time network service consumption to Service Providers’ customers is the end result.


Since the delivery of Ciena's D-NFV solution, one problem has stood out for customers based on my observations. Service Providers have been struggling with the different characteristics of individual vendor VNF platform attachment strategies for high-speed network services. Each vendor shows up with a unique combination of dependencies (DPDK, SR-IOV, Tap Interfaces, vHost, etc...) and customers have been scratching their heads trying to identify an operational model that isn’t riddled with low-level complexity.


Ciena D-NFV is an elegant solution to this challenge. A KVM-based system with Intel's fast path packet switch processing offering end customer a common NETCONF API and instantiation engine simplifying multi-vendor deliveries by taking care of previously manual configurations of VNFs. Ciena's x86 FRU (Field Replaceable Unit) Modules, leverages the Intel platform and library components for achieving a record level performance validating the benefit of vCPE while addressing new challenges that impact the accelerated adoption of a distributed NFV.
