A unified and scalable programming language for SDN

Abstract

In networking, the introduction of Software-Defined Networking (SDN) has brought many opportunities to both networking and computing community. Decoupling of the network management logic from data forwarding plane could be a key innovation in SDN that contributes to the introduction of network programmability. With the global view of the entire network, the centralized controller can manage the entire network through the customized control logic programmed for an individual use case. In this SDN, the network bandwidth is divides into multiple layers to produce various quality of network fuctions.. Network Function Virtualization became more feasible with the introduction of SDN, where the virtualized network function can move around dynamically around the network with SDN’s dynamic network reconfiguration ability. In data center, cloud providers use network virtualization in order to store and compute the data to the users through which elastic service is provided to the users. The virtualized resources are shared and leased to cloud tenants, which are provisioned from the physical resources in the data center.
