OpenContrail QuickstartProposed Project for OPNFV

Stuart Mackie – Juniper Networks

NFV/SDN Architect

OpenContrail Stack

• Allow users to quickly deploy systems for feature exploration• On laptop• Lab environments

• Support specific deployment scenarios• All-in-one OpenStack/OpenContrail/KVM deployable as stacked hypervisor on Vmware

Fusion or KVM• Stacked hypervisor with multiple compute nodes in order to test inter-server flows• Lab environment with multiple OpenStack/Contrail nodes, and compute servers

• Support for several gateway options

• This standalone project will ultimately be superseded by another project that will integrate the OpenContrail stack with Octopus and OSCAR to enable deployment of production systems

Scripted Use Cases• Stacks will be preloaded with images and configurations to support the

following use cases:• Multi-tenant infrastructure as a service• Dynamic creation and application of network policy• Creation of service chains and application of network policy to direct traffic through them• Use of OpenStack Heat templates for application stack and service chain creation• Load balancing in service chains, reverse flow symmetry, flow stability during scaling• Use of KVM hypervisor and Docker containers for VNFs• Flow mirroring to a virtualized packet analyzer• Flow-based analytics on per-network, per-VM and per TCP port basis• Path visualization for flows between VMs• Infrastructure health monitoring

• Documentation will provide step-by-step instructions for demonstration of each use case

• Gateway use cases can be implemented using OpenContrail Simple Gateway in compute nodes, or by configuring a virtual or physical router

Deliverables• Images

• OVA/QCOW2 for stacked hypervisor installs• Preloaded with images and use case demonstration configurations

• Debian package for multi-server lab install• Installation via fab utility• Scripts to load VM and VNF images and configure use case demonstrations

• Documentation • Installation• How to run each use case demonstration, including gateways
