Software-defined networking (SDN) plays a vital role in enterprise-networking and wide area networking. While it also has an emerging role in other wireless technologies such as 5G and IoT (Internet of Things), The growing number of strict SLA applications on the internet requires the network to be more scalable and fault tolerant. There is a need for research to evaluate the current state of the art of solutions in SDN and their emerging roles in other technologies. This study used a systematic literature review methodology to conduct this research. AS part of the survey, we reviewed 188 papers from 2010- 2021 and got 70 papers more relevant for our work. We only covered papers written in English. This research tries to help network engineers, administrators, and academic researchers in the domain of networking, find a better fault-tolerant solution for data plane in SDN.

Given a directed graph, G = (V, E), a path query, path(u, v), returns whether there is a directed path from u to v in G, for u, v ∈ V . Given only V , exactly learning all the edges in G using path queries is often impossible, since path queries cannot detect transitive edges. In this paper, we study the query complexity of exact learning for cases when learning G is possible using path queries. In particular, we provide efficient learning algorithms, as well as lower bounds, for multitrees and almost-trees, including butterfly networks.

Seamless Multicast : an SDN-based architecture for continuous audiovisual transport

For audiovisual network operators, end-users satisfaction is a major issue. This is the case for TDF who operates a nationwide network in France whose main purpose is to carry Digital Terrestrial Television (DTT) streams. Such audiovisual content is forwarded through multicast real-time streams which require continuity of service. Therefore, the main goal of this work is to define a new architecture to prevent impact during network healing time. The proposed architecture aims to use a pair of redundant multicast trees, and ensure their seamless resiliency. This architecture called "Seamless Multicast" takes advantage of the networkend equipment's ability to receive and combine two identical streams, complete or not. The main contribution of this paper is the development and evaluation of an algorithm for the computation of a pair of multicast trees and the associated hitless deployment scheme. Implementation requires an Software-Defined Networking (SDN) architecture, in which performance knowledge and bandwidth management are centralized in a controller. A proof of concept controller has been used for validation of the architecture's global behaviour using a virtualized environment in multiple scenarios.
