Language Abstractions for Software-Defined Networks
For the past 30 years, networks have been built the same way: out of special-purpose devices running distributed algorithms that provide functionality such as topology discovery, routing, traffic monitoring, and access control. Recent years, however, have seen growing interest in a new kind of network architecture in which a logically-centralized controller machine manages a distributed collect...
متن کاملQuality of Service Abstractions for Software-defined Networks
Software-defined networking (SDN) provides a means of configuring the packet-forwarding behavior of a network from a logically-centralized controller. Expressive, high-level languages have emerged for expressing data-plane configurations, and new tools allow for verifying packet reachability properties in real time. But SDN largely ignores quality of service (QoS) primitives, such as queues, qu...
متن کاملSoftware 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...
