The Basic Introduction of Open vSwitchTe-Yen Liu

This document provides an overview of Open vSwitch, including what it is, its main components, features, and how it can be used to build virtual network topologies. Open vSwitch is a software-defined networking switch that can be used to create virtual networks and handle network traffic between virtual machines and tunnels. It uses a distributed database, ovsdb-server, and a userspace daemon, ovs-vswitchd, to implement features like virtual switching, tunneling protocols, and OpenFlow support. Examples are provided for using Open vSwitch with KVM virtual machines and GRE tunnels to create virtual network topologies.

Pushing Packets - How do the ML2 Mechanism Drivers Stack UpJames Denton

Architecting a private cloud to meet the use cases of its users can be a daunting task. How do you determine which of the many L2/L3 Neutron plugins and drivers to implement? Does network performance outweigh reliability? Are overlay networks just as performant as VLAN networks? The answers to these questions will drive the appropriate technology choice. In this presentation, we will look at many of the common drivers built around the ML2 framework, including LinuxBridge, OVS, OVS+DPDK, SR-IOV, and more, and will provide performance data to help drive decisions around selecting a technology that's right for the situation. We will discuss our experience with some of these technologies, and the pros and cons of one technology over another in a production environment.

Room 1 - 7 - Lê Quốc Đạt - Upgrading network of Openstack to SDN with Tungste...Vietnam Open Infrastructure User Group

This document discusses upgrading an Openstack network to SDN with Tungsten Fabric. It evaluates three solutions: 1) using the same database across regions, 2) hot-swapping Open vSwitch and virtual routers, and 3) using an ML2 plugin. The recommended solution is #3 as it provides minimum downtime. Key steps include installing the OpenContrail driver, synchronizing network resources between Openstack and Tungsten, and live migrating VMs. Topology 2 is also recommended as it requires minimum changes. The upgrade migrated 80 VMs and 16 compute nodes to the SDN network without downtime. Issues discussed include synchronizing resources and migrating VMs between Open vSwitch and virtual routers.

It will cover insights into both, existing essential networking features and recent developments and will show how to use them properly. Our starting point is the network card driver as it feeds a packet into the stack. We will follow the packet as it traverses through various subsystems such as packet filtering, routing, protocol stacks, and the socket layer. We will pause here and there to look into concepts such as networking namespaces, segmentation offloading, TCP small queues, and low latency polling and will discuss how to configure them.

Linux Performance Analysis: New Tools and Old SecretsBrendan Gregg

Talk for USENIX/LISA2014 by Brendan Gregg, Netflix. At Netflix performance is crucial, and we use many high to low level tools to analyze our stack in different ways. In this talk, I will introduce new system observability tools we are using at Netflix, which I've ported from my DTraceToolkit, and are intended for our Linux 3.2 cloud instances. These show that Linux can do more than you may think, by using creative hacks and workarounds with existing kernel features (ftrace, perf_events). While these are solving issues on current versions of Linux, I'll also briefly summarize the future in this space: eBPF, ktap, SystemTap, sysdig, etc.

The document also provides an overview of the data link layer and protocols like Ethernet, PPP, and how they are implemented in Linux.

Service Function Chaining in Openstack NeutronMichelle Holley

Service Function Chaining (SFC) uses software-defined networking (SDN) capabilities to create a service chain of connected network services (such as L4-7 like firewalls, network address translation [NAT], intrusion protection) and connect them in a virtual chain. This capability can be used by network operators to set up suites or catalogs of connected services that enable the use of a single network connection for many services, with different characteristics. networking-sfc is a service plugin of Openstack neutron. The talk will go over the architecture, implementation, use-cases and latest enhancements to networking-sfc (the APIs and implementation to support service function chaining in neutron). About the speaker: Farhad Sunavala is currently a principal architect/engineer working on Network Virtualization, Cloud service, and SDN technologies at Huawei Technology USA. He has led several wireless projects in Huawei including virtual EPC, service function chaining, etc. Prior to Huawei, he worked 17 years at Cisco. Farhad received his MS in Electrical and Computer Engineering from University of New Hampshire. His expertise includes L2/L3/L4 networking, Network Virtualization, SDN, Cloud Computing, and mobile wireless networks. He holds several patents in platforms, virtualization, wireless, service-chaining and cloud computing. Farhad was a core member of networking-sfc.

BPF: Tracing and moreBrendan Gregg

Video: https://www.youtube.com/watch?v=JRFNIKUROPE . Talk for linux.conf.au 2017 (LCA2017) by Brendan Gregg, about Linux enhanced BPF (eBPF). Abstract: A world of new capabilities is emerging for the Linux 4.x series, thanks to enhancements that have been included in Linux for to Berkeley Packet Filter (BPF): an in-kernel virtual machine that can execute user space-defined programs. It is finding uses for security auditing and enforcement, enhancing networking (including eXpress Data Path), and performance observability and troubleshooting. Many new open source tools that have been written in the past 12 months for performance analysis that use BPF. Tracing superpowers have finally arrived for Linux! For its use with tracing, BPF provides the programmable capabilities to the existing tracing frameworks: kprobes, uprobes, and tracepoints. In particular, BPF allows timestamps to be recorded and compared from custom events, allowing latency to be studied in many new places: kernel and application internals. It also allows data to be efficiently summarized in-kernel, including as histograms. This has allowed dozens of new observability tools to be developed so far, including measuring latency distributions for file system I/O and run queue latency, printing details of storage device I/O and TCP retransmits, investigating blocked stack traces and memory leaks, and a whole lot more. This talk will summarize BPF capabilities and use cases so far, and then focus on its use to enhance Linux tracing, especially with the open source bcc collection. bcc includes BPF versions of old classics, and many new tools, including execsnoop, opensnoop, funcccount, ext4slower, and more (many of which I developed). Perhaps you'd like to develop new tools, or use the existing tools to find performance wins large and small, especially when instrumenting areas that previously had zero visibility. I'll also summarize how we intend to use these new capabilities to enhance systems analysis at Netflix.

SDN refers to separating the network control plane from the forwarding plane. There are two main architectural approaches for SDN: overlay models which use tunneling/encapsulation, and underlay models which manipulate flows and use a centralized controller. Open vSwitch is commonly used as the software switch in OpenStack and supports SDN protocols like OpenFlow. OpenStack's Neutron project provides APIs for SDN controllers to integrate with and configure virtual networks. OpenDaylight is an open source SDN controller that can be used with OpenStack for features like L3 routing, LBaaS, and direct integration between Nova and Open vSwitch.

OVN: Scaleable Virtual Networking for Open vSwitchmestery

OVN is a network virtualization architecture that allows for scalable virtual networking on Open vSwitch. It abstracts virtual networking from physical networking and provides the same features as physical networks. OVN uses distributed logical flows and databases coordinated by local controllers to convert logical flows to physical flows. This allows for high performance, scalable virtual networking without depending on the physical topology.
