Abstract

Network Function Virtualization (NFV) leverages the most recent virtualization and Software Defined Networking (SDN) technologies as well as cloud infrastructure elasticity to substitute hardware middleboxes by Virtual Network Functions (VNFs). However, the failure (e.g., hardware or software) of any VNF of a particular service chain leads to breaking down the entire chain and causing significant data losses, delays, and resource wastage. In this seminar, the resource optimization problem of reliability-aware Service Function Chain (SFC) will be presented. And the routing optimization with shared VNF protection and delay constraints will be discussed.
