With the explosive growth in the demand for cloud services, the Data Center and Data Center Interconnect have to achieve hyperscale and provide unprecedented elasticity and resource availability. The underlay network infrastructure has to scale to support tens of millions of physical endpoints at low cost; the virtualized overlay layer has to scale to millions of Virtual Networks connecting hundreds of millions of Virtual Machines (VMs) and Virtualized Network Functions (VNFs), and provide seamless VM and VNF mobility.In this paper, we present Hierarchical SDN (HSDN), an architectural solution that achieves hyper scale using surprisingly small forwarding tables in the network nodes. HSDN introduces a new paradigm for the forwarding and control planes, in that all paths in the network are pre-established in the forwarding tables and the labels identify entire paths rather than simply destinations. These properties of HSDN dramatically simplify establishing tunnels, and thus enable optimal handling of both ECMP and anyto-any end-to-end TE, which in turn yields extremely high network utilization with small buffers in the switches. The preestablished tunnels make HSDN the ideal underlay infrastructure to enable seamless and lossless VM and VNF overlay mobility, and achieve excellent elasticity.HSDN is suitable for a full SDN implementation, using a scalable SDN controller to configure all forwarding tables in the network nodes and in the endpoints, as well as a hybrid approach, using conventional routing protocols in conjunction with a SDN controller.

“…Moreover, labels based on SDN and MPLS are envisioned for managing the xBar data plane forwarding. The xBar concepts have been further advanced in the Orion study [223] to achieve low computational complexity of the SDN control plane. d) Optical White Box: Nejabati et al [173] have proposed an optical white box switch design as a building block for a completely softwarized optical network.…”

The emerging Software Defined Networking (SDN) paradigm separates the data plane from the control plane and centralizes network control in an SDN controller. Applications interact with controllers to implement network services, such as network transport with Quality of Service (QoS). SDN facilitates the virtualization of network functions so that multiple virtual networks can operate over a given installed physical network infrastructure. Due to the specific characteristics of optical (photonic) communication components and the high optical transmission capacities, SDN based optical networking poses particular challenges, but holds also great potential. In this article, we comprehensively survey studies that examine the SDN paradigm in optical networks; in brief, we survey the area of Software Defined Optical Networks (SDONs). We mainly organize the SDON studies into studies focused on the infrastructure layer, the control layer, and the application layer. Moreover, we cover SDON studies focused on network virtualization, as well as SDON studies focused on the orchestration of multilayer and multidomain networking. Based on the survey, we identify open challenges for SDONs and outline future directions

“…It may also move switches from one controller to another if the load on a controller is more than a pre-defined threshold. To the best of our knowledge, "Kandoo" [16] and "Orion" [17] are only architectures exploiting hierarchic frameworks. Kandoo focuses on scaling controller by decreasing the number of frequent events on the control plane since these events bring more overhead than others to the controller plane.…”

All new networking architectures come with their own problems. Software Defined Networking (SDN) has its own challenges which are needed to be addressed by researchers as well. One of the crucial problems with SDN is the control plane scalability since it is a bottleneck for its evolution. As the network grows, the number of messages a controller receives also increases. This increase puts the controller scalability in the heart of problems of SDN. In this paper, we propose a hierarchy-based network architecture along with an inter-AS routing approach with QoS. We exploit idea of levels in which networks with controllers reside and a main controller, which works like a broker, is on top of them to keep the global network state and view. Our experiment results indicate that a controller in a hierarchic setting handles 50% less number of traffic than a controller in a non-hierarchic environment.
