Policy and Resource Orchestration in Software-Defined Networks
Anduo Wang, Jie Wu · 2018
This position paper deals with policy and resource orchestration in large-scale software-defined networks (SDNs) through network function virtualization (NFV). One of the key issues in a large-scale SDN is the automated policy orchestration and efficient resource sharing. The rich set of SDN policies that collectively drive the behavior of a single SDN often interacts in complex ways. With NFV, on the other hand, multiple workloads can co-locate and use a given infrastructure simultaneously. We examine challenges related to the automated orchestration and provisions of SDN-enabled policies and software middleboxes. We propose novel solutions - optimizations algorithms and reasoning procedures - that advance the state of art SDN orchestration service.
