“…Use-case analysis [560] of management functions required by carrier networks have identified a set of requirements and existing limitations in the SDN protocol toolbox. For instance, it has been pinpointed that OF-Config [54] needs a few extensions in order to meet the carrier requirements, such as physical resource discovery, logical link configuration, logical switch instantiation, and device and link OAM configuration [560].…”

Abstract-The Internet has led to the creation of a digital society, where (almost) everything is connected and is accessible from anywhere. However, despite their widespread adoption, traditional IP networks are complex and very hard to manage. It is both difficult to configure the network according to predefined policies, and to reconfigure it to respond to faults, load and changes. To make matters even more difficult, current networks are also vertically integrated: the control and data planes are bundled together. Software-Defined Networking (SDN) is an emerging paradigm that promises to change this state of affairs, by breaking vertical integration, separating the network's control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network. The separation of concerns introduced between the definition of network policies, their implementation in switching hardware, and the forwarding of traffic, is key to the desired flexibility: by breaking the network control problem into tractable pieces, SDN makes it easier to create and introduce new abstractions in networking, simplifying network management and facilitating network evolution.In this paper we present a comprehensive survey on SDN. We start by introducing the motivation for SDN, explain its main concepts and how it differs from traditional networking, its roots, and the standardization activities regarding this novel paradigm. Next, we present the key building blocks of an SDN infrastructure using a bottom-up, layered approach. We provide an in-depth analysis of the hardware infrastructure, southbound and northbound APIs, network virtualization layers, network operating systems (SDN controllers), network programming languages, and network applications. We also look at cross-layer problems such as debugging and troubleshooting. In an effort to anticipate the future evolution of this new paradigm, we discuss the main ongoing research efforts and challenges of SDN. In particular, we address the design of switches and control platforms -with a focus on aspects such as resiliency, scalability, performance, security and dependability -as well as new opportunities for carrier transport networks and cloud providers. Last but not least, we analyze the position of SDN as a key enabler of a software-defined environment.

“…However, small network management functions are proposed with OF-Config. Few network management approaches for Software-Defined Networks (e.g., Devlic et al (2012a), Devlic et al (2012b)) were proposed using a combination between OpenFlow protocol, OF-config protocol, and management protocols like SNMP (Feit (1993)) or its successor NETCONF (Enns et al (2011)). …”

“…Information models can be found in the Novi and Geysers projects with the Novi [41] and LICL [45] proposals respectively. Finally, special mention should be given to Software Defined Networking [46], a new paradigm in network architecture and management -a promising approach [47], with its own data model, in simplifying change facilitation in the network control logic [48]. SDN enjoys broad industry support given the flexibility it offers in data center fabric management.…”
