Meridian: An SDN Platform for Cloud Network Services
Meridian is an SDN platform developed by Mohammad Banikazemi, David Olshefski, Anees Shaikh, John Tracey, and GuohuiWang at IBM T. J. Watson Research Center. The platform focuses on providing cloud network services efficiently. It encompasses an architecture that enables faster and more convenient network management through software-defined networking (SDN). Meridian's implementation offers a logical-to-physical translation layer for network orchestration, providing a global view of data center topology and various routing algorithms. Overall, Meridian aims to enhance cloud networking with its API layer, network orchestration platform, and network driver layer.

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. 11/2 0
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 12/2 0
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 OpenFlow devices Drivers to enable virtual network creation Topology data gathered 13/20
