Cloud-Native Contrail Networking

Juniper Cloud-Native Contrail Networking (CN2) is a software-defined networking (SDN) platform that automates the creation and management of virtual networks. It lets you connect, isolate, and secure workloads in both private and public clouds. Integrated with OpenStack, OpenShift, and Kubernetes, CN2 provides hybrid SDN orchestration and centralized control of virtualized switching, routing, security, load balancing, and more.

CN2 is suited to multicluster environments shared by many tenants, teams, applications, and engineering phases. It scales across virtual networks, policies, and compute instances to manage virtual network clusters of thousands of nodes in the most demanding environments.

Key Features

  • Hybrid SDN for Kubernetes, OpenShift, and OpenStack
  • Advanced routing, optional overlays, and virtual network topologies
  • Security and service chaining
  • Multicluster management / federation
  • GitOps and CI/CD pipeline services
  • Web GUI-based real time visualization, monitoring, and management
