S-NFV

Proceedings of the 2016 ACM International Workshop on Security in Software Defined Networks & Network Function Virtualization, 2016
Network Function Virtualization (NFV) applications are stateful. For example, a Content Distribution Network (CDN) caches web contents from remote servers and serves them to clients. Similarly, an Intrusion Detection System (IDS) and an Intrusion Prevention System (IPS) have both per-flow and multi-flow (shared) states to properly react to intrusions ...

Customizable Deployment of NFV Services

Journal of Network and Systems Management, 2021
Network Functions Virtualization (NFV) promotes a paradigm shift in the core network, by enabling the execution of network functions on a virtualized software plane instead of on dedicated hardware. Despite its benefits, NFV introduces new challenges, of which we highlight those related to the deployment of virtualized network services.

SPaaS-NFV: Enabling Stream-Processing-as-a-Service for NFV

2018 IEEE 8th International Symposium on Cloud and Service Computing (SC2), 2018
Network Function Virtualization (NFV) as new network paradigm provides an opportunity to accelerate network innovation in the next generation mobile network (MN). The monitoring, in this case, helps the analysis and gives better insights into the network function in real time.
