Abstract

Network function appliances such as subscriber termination, firewalls, tunnel switching, intrusion detection, and routing are currently provided using dedicated network function hardware. As network function is migrated from dedicated hardware platforms into a virtualized environment, a set of use cases with application specific resilience requirements begin to emerge. These use cases and requirements cover a broad range of capabilities and objectives, which will require detailed investigation and documentation in order to identify relevant architecture, protocol and procedure solutions to ensure reliance of user services using virtualized functions. This document provides an analysis of the key reliability requirements for applications and functions that may be hosted within a virtualized environment. These NFV engineering requirements are based on a variety of uses cases and goals , which include reliability scalability, performance, operation and automation. Note that this document is not intended to provide or recommend protocol solutions.
