Since Cumulus Linux first shipped, OpenStack and Cumulus Networks have grown together to deliver a vibrant ecosystem of solutions and multiple go-to-market options that make open networking a reality for customers.
The last OpenStack Summit in Vancouver showed that we have a lot to share with the OpenStack community.
That is why with our partners and customers, we submitted several speaking sessions. We would be thrilled to present them at OpenStack Summit Tokyo.
Support us to make this happen!
The voting period is open for a short period of time only and will close on July 30 at 11:59PM PST. Check out our submission below and Vote now to hear us at OpenStack Summit Tokyo!
VTEP: Your High-throughput Bridge from Virtual to Physical
Abstract: In this session, we will use a real-world case study to show how VXLAN tunnel endpoints (VTEPs) and VXLAN offloading can increase network throughput while reducing CPU overhead — overcoming two significant hurdles facing virtualized data centers. We will demonstrate typical applications and workloads deployed on physical and virtualized machines. On the network layer, the switches will utilize VTEP technology to allow Layer 2 connectivity over a Layer 3 network. We will display the traffic flow between the virtual and physical ports on the physical switch. Conclusion, and good news: Advances in network virtualization allow designers and architects to choose open architectures for the next generation of networking solutions.
Building an Open Source Cloud Controller with Cumulus Linux and Puppet
Asbtract: Going from a rack of bare metal to a fully functional OpenStack deployment can be a daunting task. Tools like Puppet and the OpenStack Puppet modules make it easier, but getting the initial Puppet infrastructure and networking in place is still a challenge. In this talk, we’ll walk you through how to use open tooling to build a complete OpenStack deployment with only a USB stick and a rack of network and compute hardware, using only publically available free and open source automation tooling and off-the-shelf commodity hardware.
Hierarchical Port Binding in Practice: Experiences with At-Scale Production
Abstract: This talk will discuss our experiences deploying Hierarchical Port Binding in production and at scale. We’ll compare an existing OVS+VXLAN implementation with a newer HPB+VXLAN based implementation. We’ll talk about the benefits of the newer implementation, as well as the problems we ran into along the way.
IIJ Software-Defined OpenStack Architecture
Abstract: IIJ provides a variety of reliable and highly value-added solution services, including Internet access, outsourcing, and systems integration as a comprehensive corporate group for all network usage requirements. OpenStack is core to our service offering and open solutions is essential to our architecture. The entire stack is open. Open automation and monitoring tools are leveraged across standard infrastructure; servers, storage, and networking with standard Linux distributions across the board. Overlay networking with Midonet or OpenContrail provide flexible multi-tenancy accelerated by hardware based VTEPs. The underlay network enabled by Cumulus Linux provides a common API for converged operations and a choice of network platforms. Further zero touch provisioning with PXE and ONIE facilitates image installation and configuration. The goal is to review the architectural design, best practices, and lessons learned.
Enabling Better Network Troubleshooting
Abstract: Traditional network troubleshooting tools (such as tcpdump, Wireshark and traceroute) cannot provide meaningful visibility into virtual networks. Network administrators can have difficulty troubleshooting dropped packets. Implementing chargeback and showback for virtual machine customers is difficult in an OpenStack environment. There is a solution. This session will demonstrate how open source technologies such as Zoom, Cassandra and Prometheus can be used to analyze and troubleshoot distributed networking systems, where traditional troubleshooting tools cannot penetrate. Used in conjunction with Cumulus Linux you can provide troubleshooting from end to end through both your physical underlay and your virtual overlay.
Deploying a Cumulus Underlay Network for Network Virtualization with OpenStack
Speaker: Steven Kath, Software Alliances Engineer, Cumulus Networks
Abstract: Are you interested in deploying OpenStack with overlay-based network virtualization? If so, you’ll need a physical underlay network to run it on. This hands-on lab will cover designing, building and deploying that physical network. This lab will use the built-in VXLAN support in Neutron, but the design covered is appropriate for any overlay controller, open-source or proprietary.
Thank you in advance and we look forward to seing you in Tokyo!
