With the introduction of network function virtualization technology, migrating entire enterprise
data centers into the cloud has become a possibility. However, for a cloud service provider …

Recently, the widespread use of Network Function Virtualization (NFV) has meant a
significant shift in communication and network cloud-based services. NFV increases network …

An innovative resource allocation framework for virtualized network environments and
based on the application of Artificial Intelligence techniques is proposed and investigated. It …

We propose a meta-heuristic based on the Non-dominated Sorting Genetic Algorithm II
(NSGA-II) to address the NP-Hard service function chain placement problem. This work …

A suitable virtual network function (VNF) placement considering a node availability schedule
extends service continuous serviceable time by suppressing service interruptions caused by …

Rice is the predominant staple food in Asian countries. It has a major impact on the social
and economic development of these countries. Therefore, it is very important to keep the …

In network functions virtualization (NFV), network functions are operated in software as
virtual network functions (VNFs) instead of dedicated hardware. The most important issues …

This paper proposes a sub-chain-enabled coordinated protection model for the availability-
guaranteed service function chain (SFC) provisioning, which considers the availability of …

The design of flexible and efficient mechanisms for proper placement and chaining of virtual
network functions (VNFs) is key for the success of Network Function Virtualization (NFV) …

We present an architectural design and a reference implementation for horizontal scaling of
virtual network function chains. Our solution does not require any changes to network …
