Calico plugin for Mirantis Fuel
===============================
Calicos pure L3 approach to data center networking integrates seamlessly with
Mirantis OpenStack to bring simple, scalable and secure networking to your
deployment.
Calico provides seamless, scalable, secure Layer 3 Virtual Networking for your
Mirantis OpenStack Deployment.
Based on the same scalable IP network principles as the Internet, Calico
implements a highly efficient vRouter in each compute node that leverages the
existing Linux kernel forwarding engine without the need for vSwitches. Each
vRouter propagates workload reachability information (routes) to the rest of
the data center using BGP either directly in small scale deployments or
via BGP route reflectors to reach Internet level scales in large deployments.
By replacing OpenStacks native networking model, Calico targets deployments
where the vast majority of workloads only require L3 connectivity, providing
efficient, easy to troubleshoot networking, without the complexity and
inefficiency of overlay networking models. Calico does not require any
additional nodes or Calico specific management it just works, and gets out
of your way!
Calico peers directly with the data centers physical fabric (whether L2 or
L3) without the need for on/off ramps, NAT, tunnels, or overlays.
With Calico, networking issues are easy to troubleshoot. Since it's all IP,
standard tools such as ping and traceroute will just work.
Calico supports rich and flexible network policy which it enforces using
bookended ACLs on each compute node to provide tenant isolation, security
groups, and external reachability constraints.
