Resource monitoring is a key task in network management. The concept of Software Defined Networking (SDN) allows taking benefits of the advantages of both active and passive monitoring techniques. However, this monitoring has a cost, hence the importance of the selection of the "key" switches to be interrogated and their polling frequency in order to reduce monitoring cost. This cost is expressed here in term of computing time. Monitoring of links can be used to determine the available bandwidth on each link, with the aim to meet the applicative QoS requirements based on appropriate routing. In this context, this paper first provides a formulation of the problem of choosing key switches as a vertex cover problem and proposes a heuristic method to solve the formulated problem. It then provides an implementation and a performance evaluation of the proposed algorithm within the Floodlight SDN controller. These performances are compared to those of the currently existing Floodlight monitoring module. Finally, we present one application of our proposed monitoring.

“…This view goes along with [26], which defined the long schedule of implementation as the biggest drawback [27]. The main features of the challenge consist of unexpected contact with other deployed networks, addition with legacy networks, which do not support the open flow protocol, errors of basic when emulating SDN beyond certain limits, updates of architecture and deep changes in inter-domain routing protocols, models of service and procedure of operation [28,29]. [30] recognized, in addition to practical experiments, the economic restrictions of enterprises, as SDN needs a full "SDN-enabled" network deployment of switches and a serious re-engineering of the entire topology of network.…”

In the present days, network technologies have always been an important part of success in any communication system. The internet has led to a digital society formation, where from anywhere almost everything is linked and is easily reached. Despite their widespread adoption, traditional IP networks are intricate and very hard to manage. According to predefined policies, it is hard to both configure and reconfigure the network in the case of response to faults, loads and changes. This can lead to problems in effectiveness due to the slow scalable IT infrastructure growth. In this paper, an extensive review on Software Defined Networking (SDN) is presented. Response to problems by providing novel functions to the entire network topology can be easily carried out with SDN. With software defined networking, administrators have the opportunity to abstract the underlying infrastructure of the network for applications and services. After introducing SDN, key concepts and its traditional networking differences, its roots and the activities of standardization are explained in an attempt to expect the future growth of this new model and discuss the main on-going research attempts and challenges. We formulate a scenario classification in which these technologies may contact and observe a significant degradation in the web services performances, in terms of response time and availability. At last we analyse the SDN position as the main enabler of a software-defined environment. SDN present novel networking ideals, simplifying management of network and facilitating evolution in network.

“…In terms of service provider perspective, the networks are fundamentally more complex in addition to being multilayer which entails to high availability and performance. Developing the strategies to increase revenue such as Bandwidth on Demand, Pay for Network Features and other services are the responsibilities of Telekom operators [1]. The computer networks however are designed in such a way that it should accommodate huge numbers of network elements; consisting of routers, switches, servers and other types of middleboxes.…”

“…Bandwidth-on-Demand also known as BoD is considered by researchers as one of the ways that Telekom operators can adopt to address the limit of network infrastructure and traffic data growth [1,[3][4]. The concept of Bandwidth on Demand (BOD) has been around for quite a while even though it is lacking as prime focus from Internet service providers (ISPs).…”

“…ISP is facing the problem with static network infrastructure of unable to properly be dynamic enough for Bandwidth-on-Demand due to the legacy network elements being too saturated in the network infrastructure in which removing it or upgrading it would cost a hefty amount of capital expenditure. ISP can combat this situation by integrating the current mechanism of Bandwidth-on-Demand with a software-driven force that promote flexibility and effective optimization for the control of network complexity [1]. Due to the nature of software, configuration for new changes should be improved, efficient and the time taken for the changes to take place is supposed to be instantaneous and overarching.…”

<span>Telco operators need to tailor their networks to be agile, efficient and able manage the operational cost at moderate level. Furthermore, the norm of network volatility practiced by many enterprises open to a new challenge in managing an increasing traffic over the same WAN. For an enterprise, turning toward Bandwidth-on-Demand (BoD) approach promises to deliver extra network capacity when in demand without the complexity of running separate network. However, they need to manually transform these high-level policies into low-level configuration command and thus error-prone. This study was to address the effects of SDN (software-defined network) on the BoD performance towards the differences between the reactive and intent forwarding based on the assessment matrix. The testbed was performed under Mininet simulator which interacted with ONOS (Open Network Operating System). Mesh type topology with a predetermine parameter matrix was used using random topology generator. The expected outcome from this research was to show the effect on the BoD performance under two type of forwarding; reactive and intent based on the assessment matrix. This report contributed towards determining the effectiveness of SDN architecture on BoD performance and to improve future benchmarking on SDN-BoD testbed.</span>
