“…22,41,42 YANG structures data under a hierarchical tree topology by using variables contained in modules that allow describing easily network devices and their relationships. 43 In this paper, we use YANG to define data models for SDN management since it is protocol agnostic, human readable, and easy to learn. Furthermore, it uses a hierarchical model to represent data and supports modules and submodules.…”

The lack of a Management Plane specification in the software-defined networking (SDN) is a fundamental problem for the integrated management of networks that follow this paradigm. Several solutions have addressed this problem, but they do not provide data models intended to support Fault, Configuration, Accounting, Performance, and Security (FCAPS) in SDN from a specialized Management Plane. In this paper, we introduce a technologyagnostic approach that comprises mainly a collection of YANG data models and their relationships. These models characterize SDN management and handle technology heterogeneity. To evaluate our approach, we developed the proof of concept of the YANG data models in an SDN scenario involving the configuration of devices from different vendors supporting diverse technologies. The evaluation results show the efficiency of our approach regarding response time, composition time, consumption time, and network traffic.

“…As a consequence, if YANG modules grow, the corresponding UML diagrams will grow fast as well. A proposed solution to this is the use of special filters that highlight specific information in different colors to improve readability [26]. Since the number of objects, however, remains unchanged, this does lead to a better clarity, but is limited in its effects.…”

Software Defined Networking is currently revolutionizing computer networking by decoupling the network control (control plane) from the forwarding functions (data plane) enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. Next to the well-known OpenFlow protocol, the XML-based NETCONF protocol is also an important means for exchanging configuration information from a management platform and is nowadays even part of OpenFlow. In combination with NETCONF, YANG is the corresponding protocol that defines the associated data structures supporting virtually all network configuration protocols. YANG itself is a semantically rich language, which -in order to facilitate familiarization with the relevant subject -is often visualized to involve other experts or developers and to support them by their daily work (writing applications which make use of YANG). In order to support this process, this paper presents an novel approach to optimize and simplify YANG data models to assist further discussions with the management and implementations (especially of interfaces) to reduce complexity. Therefore, we have defined a bidirectional mapping of YANG to UML and developed a tool that renders the created UML diagrams. This combines the benefits to use the formal language YANG with automatically maintained UML diagrams to involve other experts or developers, closing the gap between technically improved data models and their human readability.

Abstract-Network Service Providers are struggling to reduce cost and still improve customer satisfaction. We have looked at three underlying challenges to achieve these goals; an overwhelming flow of low-quality alarms, understanding the structure and quality of the delivered services, and automation of service configuration. This thesis proposes solutions in these areas based on domain-specific languages, data-mining and selflearning. Most of the solutions have been validated based on data from a large service provider.We look at how domain-models can be used to capture explicit knowledge for alarms and services. In addition, we apply datamining and self-learning techniques to capture tacit knowledge. The validation shows that models improve the quality of alarm and service models, and enables automatic rendering of functions like root cause correlation, service and SLA status, as well as service configuration.The data-mining and self-learning solutions show that we can learn from available decisions made by experts and automatically assign alarm priorities.
