The development of modern computer networks for internet access makes routing protocols needed, and it has an essential role in a real-time system. Therefore, the best and most effective routes can be reached. In this short article, we discuss the comparison of two popular routing protocols, i.e., Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) using two network simulators, i.e., Graphical Network Simulator-3 (GNS3) and Enterprise Network Simulation Platform (ENSP). Both of OSPF and RIP routing protocols can be used in the same topology and have differences in the connection time required to connect communication between routers. Thru GNS3 and ENSP, we obtained the comparison result at ideal condition; we found that the OSPF routing protocol (83 ms) has a faster time or efficient in connection than RIP (177 ms). Besides, we found that compared to GNS3 network simulators (329 ms), the ENSP has a relatively more rapid average time (94 ms). This work suggests that a Huawei router with ENSP is faster than a Cisco router which is used by GNS3. Hopefully, this information can be refereed by internet network administrators to build real-time computer networks.

Usually in studying the practice of computer networks, it is encountered several obstacles such as (1) limited computer networks design tools, (2) limited learning time to design computer networks and (3) technical difficulties for finding the solutions of errors. To overcome those barriers as proposed in this study, computer network simulators were used. Computer network simulators were expected to help students designing and simulating networks planned to be applied to computer network practices. This study used two simulators to compare its effectiveness in assisting the students to learn computer networks, which were Cisco Packet Tracer and Graphical Network Simulator 3 (GNS3). This study was aimed to determine the difference of the influence of network simulators to (1) learning achievement, and (2) learning achievement improvement. The quasi-experiment method was used and data were collected through conducting testing before and after the utilization of the simulators. Based on the testing results it was concluded that (1) different effect of using Cisco Packet Tracer and GNS3, the average grade achievement in the class using GNS3 and using Cisco packet tracer were 76.67 and 70 respectively, and (2) improved learning achievement using GNS3 for around 35%, higher than using Cisco Packet Tracer.

A distributed system always runs on top of a computer network and cannot be separated from it. In many cases this network consists of hundreds or thousands of computers and processing nodes. An effective distributed system simulator needs to simulate the underlying network. Unfortunately a great majority of existing simulation tools are pure network simulators. Even though they are very effective for designing, and evaluating computer networks, they could not be used to simulate a distributed application like a web service based application. Many components in a distributed system are complex servers and software applications running on top of all network layers. Network simulators cannot simulate them. A higher-level simulator is required to simulate their behavior. This work introduces an agent-based simulation model that integrates the simulation of a computer network and higher-level components of a distributed application. The distributed nature of agents makes them suitable to model and simulate distributed architectures including computer networks and distributed systems. To evaluate this approach the behavior of a replicated web service application will be simulated to show how effectively multi- agent-systems could be used to simulate the behavior of a distributed system.

The main purpose of IP next generation version 6 or called IPv6 is to meet the needs of IP addresses for the long term. With the presence of IPv6 it is also necessary routing protocol that supports IPv6 network. Routing protocols work to connect between networks, and choose paths or routes to reach other networks. There are three types of routing protocols that already support IPv6 services. Among other types of distance vector (RIPng), link-state (OSPFv3) and hybrid (EIGRPv6). This final project is designed to know the performance of the three types of routing protocols on IPv6 network. Testing is done by analyzing routing update process, ICMPv6 packet analysis and testing by sending Real-time Transport Protocol (RTP) packet in the form of audio video stream sent via server and accessed through client. In the simulation and analysis results using GNS3 (Graphic Network Simulator 3) and wireshark found that the OSPFv3 performance testing is better than EIGRPv6 and RIPng when performing routing updates or when link down occurs. Then the data analysis of test results with the delivery of Real-time Transport Protocol package so that it can be concluded that OSPFv3 algorithm better than EIGRPv6 and RIPng in terms of delay, packet loss, throughput and jitter.

Computer network conditions that are dynamic and also complex make network operators often make mistakes in the configuration of a network device. However, these mistakes can be resolved by the emergence of a centralized programming approach which is now known as Software Defined Network (SDN). In addition, with the development of information technology, several services in computer networks also grabbed a lot of attention from the world, such as video streaming services. A video streaming service that is so massive is capable of having an impact on data traffic on computer networks. In SDN networks, controllers are a core component of this architecture. Currently, many different types of SDN controllers can be used, however, choosing a controller in an SDN network must be an important concern. This is related to the performance of the SDN controller which is a requirement for SDN network development. This research will analyze the performance of the video streaming service using the Real-time Transport Protocol (RTP) streaming protocol in testing two SDN controllers, namely Pox and Opendaylight. Based on the tests that have been carried out, it produces Quality of Service (QoS) values in the form of throughput, delay, and jitter. The Pox controller excels in the value of QoS delay and throughput. As for the jitter value, both Pox and Opendaylight controllers have good indexes.

In this study, we investigated data spreading in computer networks with scale-free topology under various levels of improved clustering. Starting from a pure Barabási–Albert (BA) network topology, we applied a Poisson-based rewiring procedure with increasing rewiring probability, which promotes local connections. We then performed wired computer network simulations in NS2 simulator for these topologies. We found that for pure BA network, data transfer (throughput) is maximum, where time required for establishing routing scheme, end-to-end delays in data transmission and number of nodes acting in data transfer are at their minimum levels. Improving clustering increases these parameters those are at their minima. A noteworthy finding of this study is that, for moderate levels of clustering, total throughput remains close to its maximum yielding stable transfer rates, although number of infected nodes and end-to-end delay increase. This indicates that clustering promotes spreading phenomena in networks, although it increases average separation. As a result, clustering property emerges as a catalyzer in data spreading with minimal effects on the total amount of transmission.

An integrated multi-user system for synchronous design and analysis improves collaboration and concurrent engineering across multiple engineering disciplines. This approach allows all members of a multidisciplinary team (i.e., a team made up of designers and structural analysts) to access the same shared model over a computer network and synchronously contribute to the model in real-time. Data for both design and analysis are directly based on the same mathematical representation of the geometry, eliminating the need for model translation between disciplines. All data are stored on a central server which allows simultaneous access by multiple users. Each user views and operates on the model in a way specific to his or her discipline. Updates to the shared model are seen in real-time. This system enables an enhanced parallel product development workflow, since users from multiple disciplines can simultaneously contribute to the same engineering model. A simple implementation of an integrated multi-user design and analysis system was developed to demonstrate this method. Preliminary results from two experiments suggest a reduction in the amount of time required to perform design and analysis operations when compared with traditional, single-user approaches. Future research is suggested.

Aodv Routing Protocol

Vehicular Ad hoc Network (VANET) is a challenging network environment in which communication between vehicles in highly fading environments, like an urban scenario, is unpredictable and difficult. In order to analyze the performance of routing protocols and applications, a few of network simulators could be applied such as GlomoSim, NS -2, OPNET, QualNet and NCTUns. In this dissertation, we study either hindering object and signal strength in VANET could affected the performance of AODV routing protocol or not and what are the other factors affect AODV performance. The performance analysis of AODV routing protocols under hindering object and signal attenuator is presented via simulation using NCTUns network simulator based on dropped packet and throughput metrics. Beside simulation, this paper also presented comparative analysis for AODV measured by throughput and end-to-end delay. Based on simulation process and comparative analysis, it is observed that the performance of AODV is affected by physical hindering objects and signal strength. It is also observed that the performance of AODV is independent from the types of network simulator used in simulation process.

This chapter presents a description of a newly developed research-level computer network simulator, which can be used to evaluate the performance of a number of flooding algorithms in ideal and realistic mobile ad hoc network (MANET) environments. It is referred to as MANSim. The simulator is written in C++ programming language and it consists of four main modules: network, mobility, computational, and algorithm modules. This chapter describes the philosophy behind the simulator and explains its internal structure. The new simulator can be characterized as: a process-oriented discrete-event simulator using terminating simulation approach and stochastic input-traffic pattern. In order to demonstrate the effectiveness and flexibility of MANSim, it was used to study the performance of five flooding algorithms, these as: pure flooding, probabilistic flooding, LAR-1, LAR-1P, and OMPR. The simulator demonstrates an excellent accuracy, reliability, and flexibility to be used as a cost-effective tool in analyzing and designing wireless computer networks in comparison with analytical modeling and experimental tests. It can be learned quickly and it is sufficiently powerful, comprehensive, and extensible to allow investigation of a considerable range of problems of complicated geometrical configuration, mobility patterns, probability density functions, and flooding algorithms.
