Topic:  Improving the Flexibility and Performance of Virtual Network Functions

Abstract:  Network Functions Virtualization (NFV) was recently proposed to improve the efficiency of network service provisioning, by leveraging virtualization technologies and commercial off-the-shelf hardware. It transforms how network operators architect their infrastructure by decoupling the software implementation of network functions from the underlying hardware. However, the current commercial implementations of Virtual Network Functions (VNF) are not cloud-friendly. There is still a gap between their performance and that of the physical network functions. This talk will start with a brief overview of NFV, introducing its design principles and research challenges. It will then present two recent projects at AT&T, EdgePlex and ParaBox, on improving the flexibility and performance of VNFs. EdgePlex decomposes and virtualizes the functions of a traditional edge router and enhances its flexibility. ParaBox is a novel hybrid packet processing architecture that reduces the latency of VNFs when they are provisioned in service chains.
