ODL acts as a controller for a distributed control plane, and also an on orchestrator for Virtual Network Functions (VNFs) and Service Function Chaining (SFC). Let us now focus our attention on a SDN platform called the Open Network Operating System (ONOS). While ODL primarily solves data center use cases, ONOS is architected for the carrier-grade networks requirements of performance, high availability, and scale, with well-defined abstractions.

In this chapter, we will start with an introduction to ONOS and its ...
