In this chapter, you were introduced to Neutron, which is a networking service, and how is it different from the Nova network service. You then looked at Neutron's architecture and learnt about its components, such as Neutron server, L2 agent, and L3 agent. You also briefly learnt about networking concepts before you proceeded to install and configure Neutron.

Neutron also hopes to integrate with a pluggable IP Address Management System (IPAM) in order for enterprises to be able to easily assign IP addresses. In the coming years, Neutron will see new plugins and drivers and the overall system being made extremely modular. The ability to work with any kind of networking will soon be a reality rather than just a dream.

In the next chapter, we will look at Horizon, a portal to OpenStack.
