CONTROL SYSTEM THAT MANAGES EDGE ONLY SWITCHING ELEMENTS BUT NOT INTERIOR SWITCHES

摘要

Some embodiments provide a control system for managing a network that includes several switching elements managed by the control system and several switching elements not managed by the control system. The system includes a network information base (NIB) data structure that stores data for managing the several managed switching elements. The system includes an application interface for receiving data to store in the NIB from at least one application for controlling the managed switching elements. The system includes a switch interface for passing data from the NIB to at least one managed switching element. The managed switching elements include switching elements in an edge of the network.
