ACM SIGCOMM 2018 Full-Day Tutorial on The Role of NFV and Kernel Bypass in High Performance Networking (HPNFV)

Call For Participation

This tutorial will offer an introduction to Network Function Virtualization (NFV) technologies and in-depth hands-on understanding of an NFV platform to demonstrate their use in building high performance middleboxes and endpoint services. We will cover kernel bypass networking using DPDK, managing chains of network functions using OpenNetVM, and deploying high performance endpoint services using the mTCP user-space stack.

In order to perform the hands-on portions of the tutorial, attendees will need a laptop with internet access and basic linux and C programming skills. We will provide servers using the NSF CloudLab platform for attendees to run high performance NF chains.

Background

Network Function Virtualization (NFV) is an important area for networking at this time, as it brings much needed flexibility to accommodate innovation in an increasingly inflexible, large-scale, global network infrastructure. Recently, several high performance I/O libraries such as netmap, DPDK, and PF_RING have emerged to allow developers and researchers to build efficient NF prototypes. These libraries typically enable packet processing rates of 10 Gbps or higher by avoiding the kernel’s networking stack. While this has been a boon for accelerating individual applications, these libraries do not assist with the composition of NFs nor their management. Thus, while the low-level tools to build network functions are becoming available, there is also a need for platforms that provide the higher level abstractions needed to compose them into service chains, facilitate protocol processing, and manage their resources. This tutorial seeks to elucidate the challenges and opportunities in software-based networks by providing hands-on experience with key NFV technologies.

OpenNetVM is an NFV platform that supports both high performance networked middleboxes and end-point applications. The OpenNetVM framework provides an abstraction layer to simplify deployment of network functions in containers. It can be used not only for simple layer 2/3 middleboxes, but also integrated with a user-space TCP stack to provide end-host services. OpenNetVM is publicly available as open source on Github https://github.com/sdnfv/openNetVM.

This tutorial will provide valuable hands-on experience to researchers interested in learning about high performance network middleboxes. The tutorial will introduce attendees to an overview of NFV technology, motivation for NFV from the perspective of service providers, the DPDK I/O library, the mTCP user-space stack, and the OpenNetVM NF management platform. Attendees will get hands-on experience running a mixture of high performance middleboxes and end-host applications on an integrated platform managed by OpenNetVM.
