Network Functions Virtualization difference ppt

About NFV and difference between NFV AND SDF

1. NETWORK FUNCTIONS VIRTUALIZATION

2. WHAT IS NFV? Network Functions Virtualization (NFV) is a transformative networking concept that replaces traditional, hardware-based network functions with software-based virtualized instances. Hardware-based network functions - firewalls and routers, with software-based equivalents.

3. WHAT IS NFV? By running these Virtual Network Functions (VNFs) on standard servers and infrastructure, NFV enhances network flexibility, scalability, and cost-efficiency. It enables rapid deployment of services, and dynamic resource allocation, and centralizes management through orchestration, fundamentally reshaping the way network services are conceived, deployed, and maintained.

4. NEED OF NFV 01 02 03 Cost Efficiency: NFV reduces capital expenditure by eliminating the need for specialized hardware. Agility and Rapid Deployment: NFV enables rapid adaptation to changing network demands Resource Optimization: NFV optimizes resource usage by dynamically allocating resources

5. NEED OF NFV 04 05 06 Reduction of Vendor Lock-In: NFV boosts interoperability by allowing VNFs from various providers Centralized Management and Automation: NFV centralizes VNF management, streamlining automation. Service Innovation: NFV promotes innovative network services and applications by enabling rapid experimentation without hardware constraints

6. NFV Architecture NFV architecture consists of three key components: NFV Infrastructure (NFVI) Virtualized Network Functions (VNFs) NFV Management and Orchestration (MANO)

7. NFV Inf rastructure (NFVI): This component includes the underlying hardware resources, such as servers, storage, and networking equipment. NFVI abstracts these resources, making them available for Virtual Network Functions (VNFs) to run on. Functions NFV Management and Orchestration (MANO): MANO manages the lifecycle of VNFs, including orchestration, scaling, and monitoring. It consists of three sub-components: the NFV Orchestrator (NFVO), the Virtualized Infrastructure Manager (VIM), and the VNF Manager (VNFM). Virtualized Network Functions (VNFs): These are software instances of traditional network functions, such as firewalls, load balancers, and routers. VNFs run on the NFVI. NFV-KEY COMPONENTS At the bottom, the NFVI is the software-derived layer that mimics and allocates traditional hardware functions, including compute, storage and networking. Individual VNFs are the actual network functions that tap into the NFVI for those resources. Finally, the NFV MANO layer provides management and observability

8. Working of NFV 01 02 Decomposition of Network Function s-NFV decomposes traditional network functions like firewalls, load balancers, and routing Virtualization- where network functions are transformed into Virtual Network Functions (VNFs) using technologies like hypervisors and containers. 03 NFV Infrastructure (NFVI)- NFV Infrastructure (NFVI) comprises standard servers, storage, and networking equipment, abstracting these resources for VNF deployment. 04 VNF Management and Orchestration (MANO)- The management and orchestration layer of NFV (NFV MANO) plays a crucial role in the deployment and operation of VNFs.

9. BENEFITS OF NFV Cost Savings Agility Faster Deployment Enhanced Management Flexibility Global Expansion

10. Security Concerns Complexity Performance Issues Service Availability Due to potential vulnerabilities in virtualized components. Managing numerous VNFs in a virtualized environment can be intricate. Maintaining high availability in a virtualized environment is complex and requires robust failover strategies. Achieving hardware-like performance with VNFs may be challenging. RISKS OF NFV

11. Skill Set Gap Compliance Concerns Resource Overcommitment Integration Challenges IT teams may require new skills to manage virtualized environments effectively. Ensuring NFV compliance with industry regulations is challenging. Integrating NFV with legacy systems requires careful planning. Resource sharing in virtualization can lead to bottlenecks if not managed properly. RISKS OF NFV
