Title: Designing New Abstractions for High-Performance Network Functions


Today?s networks are responsible for more than routing packets and

perform a wide range of functionality such as firewalls, proxies, and

caches to improve performance and security. Specialized hardware

devices used to run these functions but are no longer a great choice

for cloud providers and large carriers due to high cost and low

flexibility. Software-based networking technologies such as Network

Function Virtualization (NFV) and Software-Defined Networking (SDN)

promise to offer agility, flexibility and reduce the expenditures for

network operators. However, there are challenges across the system,

application, and service layers to fully achieve these benefits.

In this talk, I will present my research on designing new abstractions

for network functions to run in software-based environments. First, I

will present OpenNetVM, an open source NFV platform that allows

researchers and developers to quickly develop and deploy network

services inside of containers. I will show how OpenNetVM achieves high

performance and flexibility by decoupling service management from the

packet processing. Then, I will present Microboxes, a novel service

chaining abstraction designed to support transport and application

layer network functions. I will show how Microboxes eliminates

redundant processing and enables a modular design by breaking the

?packet-centric? model used by existing NFV frameworks.
