Netvisor Demonstrates Dynamic Tunnel Orchestration

Open Networking User Group (ONUG) test drives Netvisor through 3rd party testing, validating 100k VMs in a leaf/spine server pod at line rates

Today, in conjunction with the Open Networking User Group (ONUG), Pluribus Netvisor advanced the forefront of SDN by going through 3rd party validation using IXIA for switch based overlay orchestration. The results validate the Netvisor architecture, and the pivotal role that SDN switching can play in data center orchestration.

Highlights of testing included:

  • Netvisor working as a distributed controller, automatically orchestrating switch hardware-based VXLAN tunnels. Based on top requirements from customers and ONUG, Pluribus networks demonstrated (with IXIA and ONUG validation) that Netvisor can orchestrate hundreds of switch-to-switch tunnels that allow 100,000 end points to talk at 95 percent of 10 Gbps line-rate with zero packet loss. This exceeded the test criteria 100 times.

  • The convergence for 100,000 end points was 25.5 seconds from a cold start and 7.35 seconds once the end points were learned by the distributed Netvisor fabric. These results were 35 times faster than the test criteria.
  • Netvisor Fabric supports open northbound and southbound interfaces in the form of an OpenStack Neutron plugin, OVSdb, and OpenFlow. In addition, Netvisor also offers REST, C and Java APIs for controlling, orchestrating, and programming the fabric. Third-party controllers can use any of these to orchestrate hardware based VTEPs instead of using Netvisor native orchestration engines.

Netvisor’s distributed fabric does not require any per VM configuration and allows end poinst to communicate by dynamically, creating encapsulation and decapsulation rules based on its global view of each VM as a vport. The architecture works equally well for bare metal servers and virtualized servers in a pod and is agnostic to server hypervisors.

Server hypervisors can run Linux/KVM, containers, or ESXi while supporting Openstack or vSphere as cloud orchestration engines. Netvisor cluster-fabrics work over BGP/ECMP fabric or allow two L2 PODS to be connected via a VXLAN tunnel thus giving users full flexibility in server deployment and network protocol.

Open Networking User Group (ONUG) Background

ONUG represents the “Who’s Who” of Fortune 100 financials, manufacturing, and services. Last October, the Network Overlay Working Group defined a set of requirements (below) that track very closely to the capabilities of Pluribus Netvisor. The focus is on openness, scale, and simplicity including monitoring and overlay-underlay visibility.

Fast-forward to this spring, and the working group’s requirements were translated into a test plan for vendors to prove their alignment to the group’s goals. Pluribus not only tested to plan, but in some cases exceeded the requirements by 100x. Our Netvisor Open Fabric Virtualization (OFV) offers the scalability and ease of management with automatic configuration that provides IT with a path to VXLAN that eliminates the ‘tunnel tax’ associated with server-based overlays in terms of both cost and performance drag on server hosts.


The early access program is available to select customers. Please contact us if you would like to be part of the Netvisor Early Access program!
