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
