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

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.
