Software Defined Networks
In previous chapters we have seen why SDN is necessary and what preceded the actual advent of SDN in the research and industrial communities. In this chapter we provide an overview of how SDN actually works, including discussion of the basic components of a Software Defined Networking system, their roles, and how they interact with one another. In the first part of this chapter we focus on the ...
متن کاملComposing Software Defined Networks
Managing a network requires support for multiple concurrent tasks, from routing and traffic monitoring, to access control and server load balancing. Software-Defined Networking (SDN) allows applications to realize these tasks directly, by installing packet-processing rules on switches. However, today’s SDN platforms provide limited support for creating modular applications. This paper introduce...
متن کاملA New Reliable Controller Placement Model for Software-Defined WANs
Software-Defined Network (SDNs) is a decoupled architecture that enables administrators to build a customizable and manageable network. Although the decoupled control plane provides flexible management and facilitates the task of operating the network, it is the vulnerable point of failure in SDN. To achieve a reliable control plane, multiple controller are often needed so that each switch must...
متن کاملScalable Emulator for Software Defined Networks
Since its inception, Software Defined Network (SDN) has made itself a very appealing architecture for both Data Center and Wide Area networks by offering more automated control through programmability and simplified network operations and management with its centralized control plane. However, extensive rollout of SDN in the production environment requires thorough validation. Thus, there is a ...
متن کاملTowards Secured Firewalls for Software Defined Networks
Software-Defined Networking (SDN) offers programmers network-wide visibility and direct control over the underlying switches from a logically-centralized controller. SDN provides a promising way for the future development of Internet. SDN, however, also has some new security challenges. A critical challenge among them is how to build a reliable firewall application for SDN. Due to the stateless...
