Scalable Programming for SDN Controllers
Introduction. A major recent development in computer networking is the notion of Software-Defined Networking (SDN), which allows a network to customize its behaviors through centralized policies at a conceptually centralized network controller. In particular, Openflow [4] has made significant progress by establishing (1) flow tables as a standard data-plane abstraction for distributed switches,...
متن کاملType systems for SDN Controllers
Software-defined networking (SDN) offers unprecedented control over network operation, allowing network operators programmatic control over switches’ forwarding behavior. In the compass-rose metaphor for networks, an SDN controller sends commands that modify switches’ forwarding tables (so-called flowmods), queues, counters, etc., by means of the southbound API. Several different southbound API...
متن کاملExploring Functional Slicing in the Design of Distributed SDN Controllers
The conventional approach to scaling Software-Defined Networking (SDN) controllers today is to partition switches based on network topology, with each partition being controlled by a single physical controller, running all SDN applications. However, topological partitioning is limited by the fact that (i) performance of latency-sensitive (e.g., monitoring) SDN applications associated with a giv...
متن کاملImpact of SDN Controllers Deployment on Network Availability
Software-defined networking (SDN) promises to improve the programmability and flexibility of networks, but it may bring also new challenges that need to be explored. The purpose of this technical report is to assess how the deployment of the SDN controllers affects the overall availability of SDN. For this, we have varied the number, homing and location of SDN controllers. A two-level modelling...
متن کاملA Clustering-based Consistency Adaptation Strategy for Distributed SDN Controllers
Distributed controllers are oftentimes used in largescale SDN deployments where they run a myriad of network applications simultaneously. Such applications could have different consistency and availability preferences. These controllers need to communicate via east/west interfaces in order to synchronize their state information. The consistency and the availability of the distributed state info...
