It first discusses the proliferation of middleboxes in enterprise networks and the necessity of
virtualizing these components just like software applications. It then details several
optimizations in operating systems to facilitate efficient networking on virtualized hardware
followed by design decisions in user-plane libraries for bypassing the kernel for efficient packet
processing. It then covers the challenges and solutions for building scalable systems for
providing networking services in datacenters, specifically the synergy between SDN and NFV to
achieve this. The course concludes with a discussion of real-world applications of NFV
technology in the cloud computing ecosystem.
