Joint Admission Control and Resource Allocation With Parallel VNF Processing for Time-Constrained Chains of Virtual Network Functions

IEEE Access, 2021
Network Function Virtualization decouples network function deployment from dedicated hardware and reduces costs. Network services are structured as chains of VNFs. Each chain is a set of VNFs that should be executed according to a predefined order.

Smart Site Diversity for a High Throughput Satellite System with Software-Defined Networking and a Virtual Network Function

Future Internet, 2020
High Throughput Satellite (HTS) systems aim to push data rates to the order of Terabit/s, making use of Extremely High Frequencies (EHF) or free-space optical (FSO) in the feeder links. However, one challenge that needs to be addressed is that the use of

Availability‐aware virtual network function placement based on multidimensional universal generating functions [PDF]

International Journal of Network Management, Volume 34, Issue 2, March/April 2024.
We propose a virtual network function (VNF) placement model on a per‐VNF instance basis that considers the availability of the service function chain (SFC). We develop an availability computation method with reduced computation time using a multidimensional universal generating function.

A comparative analysis of two‐stage approaches for embedding network function virtualization enabled multicast services

IET Communications
The Network Function Virtualization (NFV) technology has emerged to turn hardware‐based network functions into software‐based virtual entities. In NFV‐enabled multicast services, the data flow should be passed through a series of Virtual Network ...

Optimizing Service Function Chain Mapping in Network Function Virtualization through Simultaneous NF Decomposition and VNF Placement

CoRR
Network function virtualization enables network operators to implement new services through a process called service function chain mapping. The concept of Service Function Chain (SFC) is introduced to provide complex services, which is an ordered set of

VNF-P: A model for efficient placement of virtualized network functions [PDF]

10th International Conference on Network and Service Management (CNSM) and Workshop, 2014
Network Functions Virtualization (NFV) is an upcoming paradigm where network functionality is virtualized and split up into multiple building blocks that can be chained together to provide the required functionality. This approach increases network flexibility and scalability as these building blocks can be allocated and reallocated at runtime ...
