Is there a benefit to service placement algorithms that minimize the potential for network bottlenecks and contribution to overall delay in a serviced flow? What role does policy play in the service chain embedded within the chain as a decision/branch point or when expressed as multiple different chain topologies? Goals and Objectives Pre-standardization of the work in such a way that satisfies current as well as the future technical specifications and standards in ad hoc Standards Development Organizations (SDOs). In the form of an ETSI Industry Specification Group (ISG). Objectives: It includes specifying requirements and architecture. Analyzing the gap in virtualization of network functions. It ensures that the overall network operator's platform is simple and easy. It tends to achieve virtualized network functions with high performance. It must provide assurance of appropriate levels of resilience to hardware and software failure It enables the management and orchestration of VNFs. The integration of new virtualized appliances into existing management systems must be simple. Software Architecture of Network Function Virtualization Software Architecture (NFV SWA) - It defines use cases and how solutions should be structured and possibly decomposed into functional blocks. What services can be virtualized and in what method is one of the interesting questions for NFV; with regard to which, there is a spectrum of potential solutions, from the fully virtualized service running as a single VM through a multipart (a service comprised of functional sub
