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.

VNF Placement and Chaining in Distributed Cloud
2016 IEEE 9th International Conference on Cloud Computing (CLOUD), 2016This paper presents a model for Virtual Network Function (VNF) placement and chaining across Cloud environments. We propose a new analytical approach for joint VNFs placement and traffic steering for complex service chains and different VNF types. A custom greedy algorithm is also proposed to compare with our solution.
