Summary:Next Generation Mobile Network, 5G, will leverage heavily on Network Function Virtualisation for flexible and cost efficient deployments. 5G technology is to provide numerous innovative business opportunities through a key concept known as Network Slicing. This approach will require efficient placement and chaining of virtual network functions (VNFs) composing a network slice. The goal is to maximize network resources availability with minimal cost as network infrastructure is shared among different network slices. This paper proposes a time and resource-efficient VNF placement and chaining method, UA*, a Utility-based placement algorithm that extends the A* algorithm node classification set. UA* considers slice performance requirements and policies. Our simulations evaluate UA* and compares its performance with state of the art approaches.
