SDN Architecture for Cloud Netwroking Meridian 10/2 0

Abstract API layer Present application with a network model � Associated APIs that expose only the information needed to interact with the network � Logical view of the network using high-level APIs. � 11/ 20

Network Orchestration platform � Logical-to-physical translation of commands issued through the abstraction layer Convert API calls into the appropriate series of commands on the underlying network � Network-wide service to application. � Global annotated view of the data center topology for applications � Different routing algorithms � Planner module that can schedule network configuration or control task � 12/ 20

Network driver layer � Consists of plug-in or drivers enable the controller to interface with various network technologies or tools. The orchestration layer uses these drivers to issue commands on specific devices or collect information from the network. � Implemented a logical driver that interfaces to Open. Flow devices � Drivers to enable virtual network creation � Topology data gathered � 13/2 0
