报告简介：Network function virtualization enables flexible implementation of network functions, or middleboxes, as virtual machines running on standard servers. However, the flexibility also creates a challenge for efficiently placing such middleboxes, due to the availability of multiple hosting servers, capability of middleboxes to change traffic volumes, and dependency between middleboxes. In this talk, we discuss the optimal placement challenge of NFV middleboxes, and present solutions for middleboxes of different traffic changing effects and with different dependency relations. We start by showing the hardness of the studied problem, and propose optimal algorithms for special cases and efficient heuristics for general scenarios. Further, we describe our implementation of the proposed solutions using a software-defined networking approach, and present extensive experimental and simulation results to demonstrate the effectiveness of our design. At the end of this talk, we will also introduce the graduate study opportunities at Florida International University, and welcome applications from Northwestern Polytechnical University.
