A survey of network function placement
Xin Li, Chen Qian · 2016
Ranging from web caches to firewalls, network functions play a critical role in modern networks. The emerging of Network Function Virtualization (NFV) has recently gained wide attention from both industry and academia, also making the study of their placement a popular research topic. This paper surveys recent network function orchestration frameworks, and particularly the network function placement strategies. We identify their design considerations as well as the companion advantages and disadvantages for different placing strategies in this paper.
