ASON\GMPLS based optical network technology has shown high reliability recently, but the issue of unified control of optical networks has become an urgent necessity to cover problems caused by separate control between different optical network layers. The attempt to implement GMPLS-based standardized control of Internet Protocol / Dense Wavelength Division Multiplexing (IP/DWDM) networks has yielded satisfactory results but reflected significant complexity when operating in real time. On the other hand, the OpenFlow control level is offered as a promising solution to be a uniform control level for such networks, but it is not yet effective enough to control optical switch nodes. Therefore, as an intermediate step towards a unified UCP level entirely based on the OpenFlow protocol, the logical thinking for the time being is to introduce an OpenFlow/GMPLS interoperability control level that uses GMPLS to control the optical layer and the dynamic coordination between the IP layer and the optical layers. This research presents a practical application of interoperability solutions (parallel, overlapping, and integrated) for GMPLS and OpenFlow control levels applied to the ASON optical network installed in the southern region of Syria. The results have shown that the integrated solution for uniform control is superior to parallel and overlapping solutions in terms of the overall path provision latency (OPPL), at the expense of the high complexity of the design and processing of the load within the controller.

Critical review
دراسة نقدية: تعتبر هذه الورقة خطوة مهمة نحو تحسين التحكم في الشبكات الضوئية باستخدام تقنيات SDN و OpenFlow. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تحتاج إلى تحسين. أولاً، الورقة تركز بشكل كبير على الجانب النظري والتجريبي في بيئة افتراضية، مما يجعل من الصعب تقييم الأداء في بيئة حقيقية. ثانياً، تعقيد التصميم وزيادة الحمل على المتحكم في الحل المتكامل قد يكونان عقبة أمام التطبيق العملي. ثالثاً، الورقة لم تتناول بشكل كافٍ التحديات الاقتصادية واللوجستية المرتبطة بتحديث البنية التحتية للشبكات الضوئية الحالية.

Software Defined Networks (SDN) is the qualitative movement in the field of networks due to that fact that it separates the control elements from the routing elements, and the function of the routing elements was limited to the implementation of the decisions that are sent to it by the controller through the OpenFlow Protocol (OF) which is mainly used in SDN. We explain in this paper the benefit of the new concept which is presented by SDN and it makes network management easier, so instead of writing the rules on each device, we program the application in the controller, and the infrastructure devices run the received commands from the controller. In order to achieve the best performance of this technology, a Quality of Service (QoS) must be applied within it, where it includes several criteria, the most important are the used bandwidth, delay, packet loss and jitter. The most important of these criteria is the bandwidth, because by improving this standard, we can improve the rest of the other criteria. Therefore, in this paper, we provide the necessary improvement on the RYUcontroller to use the best bandwidth, which improves the quality of service in SDN.
Current traditional IP networks start to be complex as the demands of the users are ever-growing. Software Defined Network (SDN) is a new paradigm to ease the management of the network and make the network programmable by decoupling the control plane and forwarding plane (such as switch and router). A centralized controller is used to manage the control plane, and it interacts with the forwarding plane using a standardized OpenFlow protocol. However, many controllers are used recently such as POX, Ryu, ONOS, and OpenDaylight. The important question is which is the best controller to use in our network and fits our network’s goals? To answer this question, a decision-making method is proposed in this paper. First, four SDN controllers are selected, and five criteria are analyzed to collect these controllers’ properties. Then a Multi-Criteria Decision Making method named TOPSIS is used to rank the controllers and choose the best one. By applying this method, a comparative study is done to evaluate the four controllers in an environment of LAN topology, and “Ryu” controller is selected as the best one based on our criteria.
Software defined networks SDN is one of the most influential types of networks in information and communication technology compared to all traditional network technologies where there are many challenges, SDN is one of the most promising solutions fo r the Internet in the future and provides a strong network infrastructure with high specifications and low cost, and represents the future of the next generation of network engineering due to the easy division of networks, programming, monitoring, control and management through a central control, and the separation of control plane from the data-forwarding plane in SDN networks facilitates the process of managing and developing networks, as this technology is currently used in data centers and wireless networks, and is a solution to many of the problems faced by traditional networks. SDN networks are characterized by sufficient dynamism to deal with the different conditions of the network, and the controller is one of its most important components and is considered the smartest component in the network, and given the importance of choosing the appropriate controller according to the different parameters and conditions of the SDN network,in this research we conducted an analysis of the characteristics of Software defined Networks, The analysis relied on comparing SDN networks with the presence of a single OpenDaylight controller (ODL) and the presence of several controllers ODL, OpenDaylight controller was chosen as one of the famous controllers and it is distinguished from others as an open source and contains a distributed datastore and is designed to suit the data center environment, Taking into account the OpenFlow protocol supported on the southern interface by this controller, the research includes simulations of software defined networks topologies using the Mininet emulator, and various scenarios and parameters such as data rate, packet delay, and throughput were analyzed by the D-ITG tool.
The mapping of Layer 3 (IP) to Layer 2 (MAC) addresses is a key service in IP networks, and is achieved via the Address Resolution Protocol (ARP) protocol in IPv4. Due to its stateless nature and lake of authentication, ARP is an easy goal to spoofin g attacks, which can enable Denial of Service (DoS) or Man-in-the-Middle (MIM) attacks. In this search, we discuss the problem of ARP spoofing in the context of Software Defined Networks (SDNs). We studied important parameters such as throughput, delay and the availability of the network. Results showed that ARP spoofing attacks was able to make a negative effects on network performance
In this paper we introduce a specification model for the host migration process in Software Defined Network, and for verifying the reachability property for packets that do not change after the migration, and achieve the required modifications to meet the same properties. The model is designed by TLA+ language and verified by TLC which is correlated with it. The model is implemented by few states to meet the required property.
