The centralized architecture in software-defined network (SDN) provides a global view of the underlying network, paving the way for enormous research in the area of SDN traffic engineering (SDN TE). This research focuses on the load balancing aspects of SDN TE, given that the existing reactive methods for data-plane load balancing eventually result in packet loss and proactive schemes for data plane load balancing do not address congestion propagation. In the proposed work, the SDN controller periodically monitors flow level statistics and utilization on each link in the network and over-utilized links that cause network congestion and packet loss are identified as bottleneck links. For load balancing the identified largest flow and further traffic through these bottleneck links are rerouted through the lightly-loaded alternate path. The proposed scheme models a Bayesian Network using the observed port utilization and residual bandwidth to decide whether the newly computed alternate path can handle the new flow load before flow admission which in turn reduces congestion propagation. The simulation results show that when the network traffic increases the proposed method efficiently re-routes the flows and balance the network load which substantially improves the network efficiency and the quality of service (QoS) parameters.

“…In terms of privacy protection, in a hierarchical model, higher-level network organizations should play a role as top-level SDN controllers (for example, root controllers). At the same time, lower-level organizations play a role as subordinate SDN controllers [26]. All local SDN controllers can share abstract local network status to the root SDN controller.…”

Web Abstraction Leads to the Generation of Software-Defined Networking (SDN). SDN unique unique CNC separation structure to control the liberation. The development background of SDN is introduced, the most mainstream SDN structure is analyzed, which is divided into three layers: application plane,data plane and control plane. The key technologies of each plane of SDN three-layer structure are studied, and the advantages and disadvantages of each technology are compared. Then the existing application fields of SDN were investigated, and finally the development trend of SDN was prospected. IntroductionWith the rapid development of network technology and the increasingly complicated interlacement between human life and network, the scope of the Internet is getting larger and larger. The traditional network architecture and the carrying capacity of devices to the network are undergoing tremendous tests. Software defined network (SDN) separates control functionality from traditional networks to create a centralized logical control plane that can be used to formulate services and rules for different needs at the root, and to translate these into data-Flow table issued. This mode of operation provides greater space for increased network utilization and cost savings.In the traditional routing mode, both the inside and outside of the domain are forwarded according to the destination IP. The control plane temporarily stores the routing information in the routing table and stores the IP and other information in the FIB of the TCAM during forwarding. When faced with large-scale network traffic, routing forwarding work faces enormous challenges.It is the traditional network architecture, there are a variety of problems, new, revolutionary network technology and architecture almost certain. SDN technology, which originated from Stanford's Clean Slate research project [1] in 2006, introduced the idea of CNC separation in 2009, separating control from data forwarding. The data layer switch only bears the forwarding function, and the control plane will be all the information and control functions delivered to the controller unified deployment. The use of a unified interface between two planes for information interaction. The controller sends the forwarding rules to the lower switch through the interface protocol, and the switch only needs to be executed according to the rules. This improves the overall control performance and reduces the cost.The successful case of SDN technology deployed by Google in 2012 on the backbone network has increased the utilization of the network to more than 70% and has become a landmark event in the application of SDN technology. Since then, the world's major companies have subsequently released their own solutions for SDN thereafter. SDN appeared at Ethane [2], a Stanford University laboratory research project, but has become a hot spot in the world for network technology and is considered as one of the key technologies of the next generation Internet [3].This article starts from the three aspects o...

Using multicast data transmissions, data can be efficiently distributed to a high number of network users. However, in order to efficiently stream multimedia using multicast communication, multicast routing protocols must have knowledge of all network links and their available bandwidth. In Software Defined Networks (SDN), all this information is available in a centralized entity-SDN network. This work proposes to utilize the SDN paradigm to perform network-resources aware multicast data routing in the SDN controller. In a prototype implementation, multicast data is routed using a modified Edmonds-Karp algorithm, by taking into account network topology and links load information. This paper presents the algorithm, implementation details, and an analysis of the testing results.
