A Dynamic Programming Algorithm for Joint VNF Placement and Chaining
Proceedings of the 2016 ACM Workshop on Cloud-Assisted Networking, 2016 This paper addresses the problem of Virtualized Network Functions placement and traffic steering in Cloud infrastructures. We design an efficient dynamic programming (DP) algorithm for joint VNF placement and traffic steering that runs in polynomial time.

Towards an efficient VNF placement in network function virtualization
Computer Communications, 2019Abstract Network Function Virtualization (NFV) decouples network function (also called middlebox function) software from specified appliances onto general shared servers. Thus, it has been being regarded as a promising technology to overcome high Capital Expenditures (CAPEX) and Operational Expenditures (OPEX) on the middlebox deployment and ...

End-to-End Performance-Based Autonomous VNF Placement With Adopted Reinforcement Learning [PDF]
IEEE Transactions on Cognitive Communications and Networking, 2020 The autonomous placement of Virtual Network Functions (VNFs) is a key aspect of Zero-touch network and Service Management (ZSM) in Fifth Generation (5G) networking. Therefore, current orchestration frameworks need to be enhanced, accordingly.

Cost as Performance: VNF Placement at the Edge
IEEE Networking Letters, 2021This letter studies the virtualized network function (VNF) placement problem for edge systems, where the edge nodes can provide services that are originally deployed in cloud datacenters. As related to the end-users, edge supports low latency when the energy consumption of edge nodes and end users are the main concerns.
