Introdução ao Edge Computing
Virtualização de Redes NFV
Networking Function Virtualization - NFV
NFV – Network Function Virtualization
Software Defined Network - SDN
Network Functions Virtualization (NFV) A network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks, to create communication services

Network environment
Network functionalities at home equipment are minimised, making them as simple and stable along
the time as possible, whereas quick evolution can be supported by SW inside operator’s network.
Simplification removes all incompatibilities with IPv6
IPv6 only needed in network environment
Operation and service deployment are greatly
simplified

Enterprise IT Workloads▪ Web serving, transaction processing and big data
analytics
▪ The capacity of most virtualized Enterprise IT applications is determined primarily by CPU utilization rather than network I/O
Telecom Workloads▪ Data plane workloads for routing, switching,
relaying or processing of network traffic payloads
▪ These kinds of workloads are I/O intensive, often requiring some combination of total I/O bandwidth and packets-per-second throughput that are orders of magnitude greater than typical of IT workloads

NFV Adoption Factors▪ Relative immaturity of existing NFV solutions▪ Challenges of the OpenStack platform▪ Need for integration▪ Lack of a path to end-to-end orchestration and
integration with OSS
Conclusion: the field is still wide open
