GNFC: Towards Network Function Cloudification [PDF]
, 2015 An increasing demand is seen from enterprises to host and dynamically manage middlebox services in public clouds in order to leverage the same benefits that network functions provide in traditional, in-house deployments.

Managing NFV using SDN and control theory [PDF]
, 2015 Control theory and SDN (Software Defined Networking) are key components for NFV (Network Function Virtualization) deployment. However little has been done to use a control-theoretic approach for SDN and NFV management.

Analytical modeling for Virtualized Network Functions [PDF]
2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017 Network Function Virtualization (NFV) is considered one of the key technologies for the 5G mobile networks. In NFV, network functions are implemented in software components denominated Virtual Network Functions (VNFs) running on commodity hardware. In this paper, we propose an analytical model based on an open queuing network of G/G/m queues to model ...

Journal of Physics: Conference Series, 2021 Abstract This paper mainly studies the optimization of dynamically arrived SFCs deployment in the SDN scenarios, and optimizes the end-to-end delay and bandwidth consumption during the deployment. First we build the model of the optimization problem, it is expressed as a 0-1 planning problem. We use ILP to get the optimal solution, cause

Optimal orchestration of virtual network functions [PDF]
Computer Networks, 2018 -The emergence of Network Functions Virtualization (NFV) is bringing a set of novel algorithmic challenges in the operation of communication networks. NFV introduces volatility in the management of network functions, which can be dynamically orchestrated, i.e., placed, resized, etc. Virtual Network Functions (VNFs) can belong to VNF chains, where nodes

Efficient Virtual Network Function Placement Strategies for Cloud Radio Access Networks
, 2018 The new generation of 5G mobile services places stringent requirements for cellular network operators in terms of latency and costs. The latest trend in radio access networks (RANs) is to pool the baseband units (BBUs) of multiple radio base stations and

Online VNF Scaling in Datacenters [PDF]
, 2016 Network Function Virtualization (NFV) is a promising technology that promises to significantly reduce the operational costs of network services by deploying virtualized network functions (VNFs) to commodity servers in place of dedicated hardware ...

Generalized virtual networking: An enabler for service centric networking and network function virtualization [PDF]
2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks), 2014 In this paper we introduce the Generalized Virtual Networking (GVN) concept. GVN provides a framework to influence the routing of packets based on service level information that is carried in the packets. It is based on a protocol header inserted between the Network and Transport layers, therefore it can be seen as a layer 3.5 solution.
