[Contrail](http://www.juniper.net/us/en/products-services/sdn/contrail/contrail-networking/), based on [OpenContrail](http://www.opencontrail.org), is a truly open, multi-cloud network virtualization and policy management platform. Contrail / OpenContrail is integrated with various orchestration systems such as Kubernetes, OpenShift, OpenStack and Mesos, and provides different isolation modes for virtual machines, containers/pods and bare metal workloads.
### DANM
[DANM](https://github.com/nokia/danm) is a networking solution for telco workloads running in a Kubernetes cluster. It's built up from the following components:
* A CNI plugin capable of provisioning IPVLAN interfaces with advanced features
* An in-built IPAM module with the capability of managing multiple, cluster-wide, discontinuous L3 networks and provide a dynamic, static, or no IP allocation scheme on-demand
* A CNI metaplugin capable of attaching multiple network interfaces to a container, either through its own CNI, or through delegating the job to any of the popular CNI solution like SRI-OV, or Flannel in parallel
* A Kubernetes controller capable of centrally managing both VxLAN and VLAN interfaces of all Kubernetes hosts
* Another Kubernetes controller extending Kubernetes' Service-based service discovery concept to work over all network interfaces of a Pod
With this toolset DANM is able to provide multiple separated network interfaces, the possibility to use different networking back ends and advanced IPAM features for the pods.
### Flannel
