Software Defined Networks (SDN) & Network Functions Virtualization (NFV)
Software-defined Networking (SDN) is a new approach to designing, building and managing networks. It has evolved from original research work done at UC Berkeley and Stanford University. SDN allows network administrators to quickly and easily manage network services from a centralize location without having to manually configure each individual network element (switch/router). This is done through abstraction of lower layers functionality.
The basic concept of SDN is to make network control decisions from centralized location. This is done by decoupling and optimizing the system that makes switching/routing decisions and other control functions such as signalling (the control plane) from the underlying systems that forwards traffic to the selected destination (the data plane).
SDN requires some mechanisms for the centralized controller (such as Open Daylight or Open Network Operating System (ONOS) to communicate with the distributed data plane. This interface is also called Southbound interface. One such southbound interface is OpenFlow. The Open Networking Foundation was founded to promote SDN and OpenFlow by specifying the OpenFlow Application Programming Interfaces (API) for connecting between Software Defined Controllers and switches/routers.
SDN environment also utilizes open application programmatic interfaces to support the communication between applications and their controller (also called Northbound Interface). Northbound APIs enable efficient service activation, management and automation.
The goal of Network Virtualization (NV) is to simplify, optimize, and enhance the network by creating logical networks that are decoupled from the underlying physical hardware. Network Functions Virtualization (NFV) simulates hardware platforms, such as firewall or storage, using software components. This allows the usage of “off the self” computing platforms and therefore cost savings.
This technology will be applicable to the deployment of major carrier networks, engineered for the delivery of carrier services through performance controlled interfaces such as those used in Carrier Ethernet networks. It will also be widely used in enterprise Cloud Computing systems.
This course describes the basic concepts of Software Defined Networks and the market drivers for these emerging technologies, The course looks at the different emerging flavours of Software Defined Networks. In addition, the course discusses the various flavors of north and southbound interfaces (their data models and protocols).
The course also discuss different approaches for virtualization, how they can be used to model and deploy network and service functions in cloud computing environments as well as Network Function Virtualization and the environment and tools (such as OpenStack) for monitoring and managing such functions.
