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.

Strategies for VNF Placements in Large Provider Networks
Optical Fiber Communication Conference, 2017We examine three strategies of VNF placement in a provider network: static service chains; seamless VNF duplication and VNF-dynamic-splitting. A constrained optimization applied to a large provider evaluates these strategies and showcases cost-latency trade-off.

Accommodating Dynamic Traffic Immediately: A VNF Placement Approach
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019Network function virtualization has become a promising technology recently. To accommodate dynamic traffic such as burst, NFV can scale virtual network functions (VNFs) across several physical servers, which is known as horizontal scaling, or enlarge the capacity of a VNF leveraging idle resources in one physical server, which is called vertical ...

Reliability-Aware VNF Placement Using a Probability-Based Approach
IEEE Transactions on Network and Service Management, 2021Network function virtualization (NFV) is a new network architecture concept that simplifies the deployment of network services and improves service management. However, it is challenging for a network service provider (NSP) to decide where to place virtual network functions (VNFs).

Distributed Approach to Adaptive VNF Manager Placement Problem
2019 20th Asia-Pacific Network Operations and Management Symposium (APNOMS), 2019Network function virtualization (NFV) has been a promising approach to flexible and scalable deployment of network services. In NFV management and orchestration (NFV-MANO) architectural framework, VNF managers (VNFMs) should be deployed to manage the lifecycle of virtualized network functions (VNFs). VNFM placement problem (MPP) is to deploy VNFMs that

Energy Efficient Algorithm for VNF Placement and Chaining
2017 17th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGRID), 2017This paper addresses energy efficient VNF placement and chaining over NFV enabled infrastructures. VNF placement and chaining are formulated as a decision tree search to overcome this NP-Hard problem complexity. The proposed approach is an extension of the Monte Carlo Tree Search (MCTS) method to achieve energy savings using physical resource ...
