Open Infrastructure Event
The open infrastructure landscape is changing, and so is the Summit. Now that users are integrating dozens of open source tools into a modern stack that reaches well beyond the scope of OpenStack, we’re re-organizing the event to focus on specific problem domains like container infrastructure, edge computing and CI/CD and we are focusing on the hard work of integrating all of these tools developed in disparate communities. This is the essential work of 2018 and beyond, to ensure that open infrastructure is truly a viable path for operators.
Open Infrastructure Event
Join the movement behind the most widely deployed open source cloud platform. Whether you are pursuing a private, hybrid or multi-cloud approach, the OpenStack Summit is the place to network, skill up and plan your cloud strategy.
Telco and Enterprises are looking for high performance, secure and scalable network infrastructure while building nextgen datacenters for NFV & SDN deployments. Top requirements are:
- Scale-up services with analytics: millions of mobile flows; video, voice, data
- High performance: 25G to 100G per Server
- Optimized resource usage
- Multi-site deployments: efficient multi-tenancy using SDN overlay
- Integrated end-to-end solution with no vendor lock-in
In this talk, RedHat, Nuage Networks & Mellanox will address these challenges in a solution centric manner bringing together 3 key components of NFV & SDN infrastructure: Openstack, SDN Controller & SmartNICs. We will describe the modifications to many open source components including Linux kernel, OVS & OpenStack (Neutron, Nova & OVS ML2), to enable a vendor agnostic, open source and community driven OVS offload solution that’s radically different, offers blazing high speeds up to 100Gbps/VNF and has no trade-offs.
- Requirements for next-gen SDN/NFV datacenters: 5G, IoT and mobile applications will demand more from the infrastructure
- What is OVS Offload to SmartNICs? How does it meet the needs of next-gen SDN/NFV Datacenter?: 25G+ speeds with SR-IOV no CPU overhead. Offload OVS flow rules and actions, traffic classification, QoS marking, encap/decap tunneling, NAT, firewall ACL filtering, TCP connection tracking, DPI and DDoS prevention. If offload fails, fall back to OVS slow-path. Offload millions of flows with firewall rules and connection tracking.
- Tradeoffs between datapath options; SR-IOV, OVS-DPDK and OVS Offload
- Dive into OVS Offload options: SR-IOV with OVS offload, partial offload with OVS-DPDK, VirtiO options with live migration
- Community activities including Linux kernel TC/flower, OVS match and action offload, Openstack upstream work for Neutron, Nova and ML2 (OS-VIF)
- Limitations of OVS offload with SmartNICs - Features dependent NIC vendor, bonding within NIC only, limited live migration support with VirtIO
- Proof of Concept results of integrated solution with performance analysis of OVS Offload with VLAN and VXLAN
