Verizon and Big Switch speak at OpenStack Summit
Chris Emmons, Director - Network Infrastructure Planning, Verizon and Kyle Forster, Founder, Big Switch, talk with Stu Miniman at OpenStack Summit in Austin, TX.
Network Fabric Virtualization (NFV) Deployments represent some of the most demanding workloads in OpenStack clouds, yet the economic and operational promise of NFV makes this a high-value technical challenge for service providers worldwide. Recently, Dell, Red Hat and Big Switch Networks collaborated to create the industry’s largest deployment of NFV infrastructure to date. Read the Verizon Press Release.
Key network design challenges for OpenStack NFV deployments fall into 5 major categories:
- Performance at Scale: To achieve scale for large NFV deployments, designs should follow a hyperscale-inspired “core and pod” approach, see Core and Pod Overview
- No Bandwidth Bottlenecks: NFV workloads put extreme stress on the network in many dimensions - east/west bandwidth, north/south bandwidth, intra-vSwitch bandwidth and logical L2/L3 bandwidth. A modern leaf-spine CLOS architecture, using centralized SDN control designed to operate the network from spine to leaf to vSwitch presents the optimal answer for large NFV deployments.
- Flexible Design with Built-in Service Chaining: Pod designs need to accommodate NFV workloads that have unique logical network requirements, yet share the same physical leaf/spine fabric and vSwitches. Additionally, NFV workloads demand per-tenant service chaining across various virtual network functions (VNFs) and need to be provisioned and managed in an automated manner.
- Resiliency & Reduced Operational Complexity: NFV designs can be incredibly complex, representing unbounded operational risk. A combination of OpenStack and Pod design can address those risks, ease of deployment and management of day-to-day operations are critical design elements.
- Integrated Security & Analytics: To ensure that NFV Pods are compliant and secure against intrusions and other threats, it is important to design an out of band monitoring capability for east/west traffic, as well as an inline protection mechanism for north/south traffic as part of the overall design.
