scholarly journals Implementation Based Approach to analyze MPLS and Segment Routing Traffic by Using ODL SDN Controller

Network infrastructure in the data center is getting more complicated due to heavy network traffic, by increasing a network load leads high storage consumption and high deployment cost. We have proposed an effective traffic management mechanism by combining Segment Routing and Multipath Transmission Control Protocol TCP in a logically centralized controller environment. Segment Routing and Multipath TCP is used to define a logically centralized and physically distribution for Software Defined Network SDN. Segment Routing SR technology is used for simplifying Multi-protocol Label Switching MPLS and software- defined network SDN networks. Segment Routing makes it easy to assign a dynamic traffic according to customer’s requirements through the high-level application. This work presents a comprehensive comparison between MPLS and Segment Routing Traffic Engineering, both technologies are implemented in an SDN network environment, based on GNS3 network Emulator as data network Layer, Open-Daylight as SDN Controller, and Python scripts for sending Segment IDs as a part of network Orchestrator in Application Layer.

Software Defined Network (SDN) provides high service flexibility to optimize network configuration based on network traffic. Traffic management able to solve traffic density in SDN. However, it will misuse the network bandwidth and links. One variant of the SDN controller, namely Open Network Operating System (ONOS), provides an Intent Monitor and Reroute (IMR) method that can optimize traffic management based on the description of an object in the ONOS application. This method can optimize the network bandwidth and links of SDN. The IMR can monitor the network and reconfigure the network to restore network connectivity by maximizing the use of each link when transmitting data. This study examines the impact of using IMR with a custom topology on ONOS to find the best scenario by performing traffic management on a data plane consisting of switches totaling 8-12 switches. The parameters measured in this study are bandwidth usage and quality of service (QoS). The results obtained in this study are IMR able to optimize the use of each link and maximize bandwidth usage in a network when distributing data and following TIPHON standards

In the era of Internet of Things and 5G networks, handling real time network traffic with the required Quality of Services and optimal utilization of network resources is a challenging task. Traffic Engineering provides mechanisms to guide network traffic to improve utilization of network resources and meet requirements of the network Quality of Service (QoS). Traditional networks use IP based and Multi-Protocol Label Switching (MPLS) based Traffic Engineering mechanisms. Software Defined Networking (SDN) have characteristics useful for solving traffic scheduling and management. Currently the traditional networks are not going to be replaced fully by SDN enabled resources and hence traffic engineering solutions for Hybrid IP/SDN setups have to be explored. In this paper we propose a new Termite Inspired Optimization algorithm for dynamic path allocation and better utilization of network links using hybrid SDN setup. The proposed bioinspired algorithm based on Termite behaviour implemented in the SDN Controller supports elastic bandwidth demands from applications, by avoiding congestion, handling traffic priority and link availability. Testing in both simulated and physical test bed demonstrate the performance of the algorithm with the support of SDN. In cases of link failures, the algorithm in the SDN Controller performs failure recovery gracefully. The algorithm also performs very well in congestion avoidance. The SDN based algorithm can be implemented in the existing traditional WAN as a hybrid setup and is a less complex, better alternative to the traditional MPLS Traffic Engineering setup.

Intersections are the most important regions in terms of urban traffic management. The intersection areas on the corridor should be analyzed together for consistency in traffic engineering. To do so, three intersections on the Vatan Street corridor in İstanbul, the most crowded city of Turkey, were examined. Various geometric and signal designs were performed for intersections and the most suitable corridor design was analyzed. The corridor designs were modeled with the PTV VISSIM microsimulation software. The most suitable corridor design was evaluated by using the results obtained from the microsimulation via analytical hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) from multi criteria decision analysis (MCDA) methods. The evaluation criteria in the study are vehicle delay, queue length, stopped delay, stops, travel time, vehicle safety, CO emission, fuel consumption, and construction cost. As a result, the current and the most suitable alternative corridors were compared according to the comparison parameters and up to 80% improvements were observed. Thus, some advantages were obtained in terms of energy, environment, time, and cost.

In this day people are asking for a reliable network when technology at its limit. Software-Defined Network (SDN) is an answer to that problem of network development where all the control over the network becomes centralized. However, all services controlled by a centralized controller have a big disadvantage if the controller dies. The High Availability (HA) is the solution. HA controller is divided into master and slave, when master controller is down then slave controller will respond to replace the function of master controller. In this research the system will be made by using two methods namely OpenDayLight SDN Controller Platform (OSCP) clustering and Heartbeat-DRBD (Distributed Replicated Block Device). OSCP clustering is a feature on OpenDayLight controller that is ready to be used and only need to be configured, with OSCP the main and backup controller clustering will be on connected cluster. Heartbeat-DRBD is an application commonly used to create High Availability systems on a server, but in this study will be used for the controller, Heartbeat will monitoring the main controller and if indicated to be down will move the resources to the backup controller with the DRBD application. From the simulation result shows that OSCP Clustering Failover and Failback average Time is 17 seconds while Heartbeat-DRBD is 23-45 seconds depends on how many switch and host are.While QoS parameters on both method have simillar value.it can be concluded that the High Availability system with OSCP Clustering method is more stable and good rather than Heartbeat-DRBD method to apply in a network.

This article deals with issues in the field of traffic engineering. According to its assumptions, traffic is a system consisting of three inseparable elements which are man, vehicle and road. In this article, the author focuses on the relationship between two of these elements: human as a road user and a path that should be a subordinate of the user’s capabilities and convenience. The first part of the article is an introduction to the topic of the article. There are presented the data on the amount of road traffic accidents caused by human factors and the categories of errors committed by drivers. In the further part there were analyzed the biological factors which have influence on driver’s actions such as sight, attention and reaction time with particular emphasis on the imperfections of those factors which should be taken into account when designing roads and organizing traffic because it lets to provide a higher level of road safety. The purpose of this article is to develop practical conclusions for road design and traffic management that will help to better adjust the road transport infrastructure to the capabilities and natural limitations of the human person. These conclusions are included in the summary.
