Raciocínio Baseado em Casos para a Configuração de Modelos de Alocação de Banda

The extensive adoption of computer networks, especially the Internet, using services that require extensive data flows, has generated a growing demand for computational resources, mainly bandwidth. Bandwidth Allocation Models (BAM) have proven to be a viable alternative to network management where the bandwidth resource is shared to meet the high demand for the network. However, managing these networks has become an increasingly complex task, and solutions that allow for nearly autonomous configuration with less intervention of the network manager are highly demanded. The use of Case-Based Reasoning (CBR) techniques for network management has proven satisfactory for decision making and network management. This work presents a proposal for network reconfiguration based on the CBR cycle, intelligence, and cognitive module for MPLS (Multi-Protocol Label Switching) networks. The results show that CBR is a feasible solution for auto-configuration with autonomic characteristics in the MPLS using bandwidth allocation models (BAMs). The proposal improved the general network performance.

Performance of VoIP Using Routing Open Shortest Path First with Multi-Protocol Label Switching

Voice over internet protocol is a communication technology in the world of computer network that can be used for sending voice or video and data transmission over Internet Protocol in real time. VoIP network can be implemented with Asterisk applications as a server to a Private Automatic Branch eXchange applied in a Graphical Network Simulator 3. In this study, VoIP communication using routing OSPF within MPLS will be calculated, the QoS value collected based on impact performance under normal condition and not normal condition (link failure) different varian bandwidth in the network. The results from the simulation show that in normal condition and not normal condition there is average delay value with routing OSPF 4 ms and routing OSPF with MPLS 5 ms, the value of jitter max which same of 6 ms using varian bandwidth from 256 kbps and 512 kbps. All of the QoS parameters, such as delay, jitter and packet loss will be compare to standard ITU-T G.114. This research can be extended with addition of another measurement or another protocol.

Analisa QoS Pada Jaringan MPLS Ipv6 Berbasis Routing OSPF

Multi Protocol Label Switching (MPLS), merupakan arsitektur jaringan yang didefinisikan oleh IETF untuk memadukan mekanisme label swapping di layer dua dengan routing di layer tiga yang berguna untuk mempercepat pengiriman paket Routing eksplisit memberikan semua keuntungan MPLS, termasuk kemampuan melakukan traffic engineering dan routing kebijakan. Kecepatan transfer data menjadi masalah yang sering dialami dalam jaringan komputer, sehingga diperlukan proses yang cepat untuk mengatasi pengiriman dan pengambilan data tersebut dengan mengutamakan efisiensi waktu, sehingga user tidak perlu membuang banyak waktu. Dengan demikian, dibuatlah sebuah jaringan komputer dengan memanfaatkan teknologi berbasis Multiprotocol Label Switching (MPLS).Jaringan MPLS ini merupakan jaringan yang akan menambahkan label pada setiap paket yang akan dikirimkan, dengan pelabelan ini maka data yang akan dikirimkan akan menjadi lebih cepat sampai pada tujuan. Hal ini dikarenakan router hanya akan menganalisa label yang diberikan pada tiap paket.Pada tugas akhir ini akan menitikberatkan pada pembangunan aplikasi jaringan secara test-bed yangmampu merepresentasikan MPLS pada jaringan IPv6 berbasis OSPF beserta analisis terhadap parameter QoS dari hasil pengukuran. Pada tugas akhir ini menitikberatkan pada pembangunan aplikasi jaringan secara test-bed yang mampu merepresentasikan MPLS pada jaringan IPv6 beserta analisis terhadap parameter QoS. Dari hasil pengukuran didapatkan bahwa jaringan MPLS (Multi Protocol Label Switching) akan bekerja secara optimal apabila terdapat banyak switching dalam sebuah jaringan, selain itu jaringan MPLS akan terasa dampaknya jika pengiriman data dilakukan dalam kapasitas ber-gigabyte.

Service-aware LSP selection with fuzzy based packet scheduling scheme for non-real time traffics

An essential solution is available in Multi-protocol label switching (MPLS), which solve the problems faced by present-day networks: speed, scalability, quality-of-service (QoS) management, and traffic engineering. This paper is an extension of work on Fuzzy based Packet Scheduling Algorithm (FPSA) combined with Packets Processing Algorithm (PPA) in an Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) networks. This will make provision for an intelligent service to the Label Switched Path (LSP) in MPLS networks. Several research work have been proposed on the MPLS Traffic Engineering. However, it is still imperative to further research on the effect of bandwidth increment on the core network using different mechanisms such as the analytical model of MPLS, expert-based packet scheduling algorithm for MPLS QoS support. Since MPLS is not able to provide intelligent routing, it is necessary to propose an intelligent expert system of FPSA combined with PPA. And analytical model of packet forwarding in the MPLS network would be given to provide suitable solution to traffic congestion and reliable services. Furthermore, the network model created using Network Simulator (NS 2), which carries non-real time application such as File Transfer Protocol (FTP) with bandwidth variations. The results obtained from trace files are interpreted by AWK script and used for the further analysis.

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.

Termite inspired algorithm for traffic engineering in hybrid software defined networks

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.

SDWAN (Software Defined-WAN) Technology Evaluation and Implementation

Many organizations are struggling to provide high bandwidth and reliable internet connectivity at their branch offices and business locations and getting the most out of their operational expense. The need for internet connectivity at any branch offices and business locations is no longer a luxury but is a necessity. Let us try to understand how to replace the traditional MPLS network with the new SDWAN (Software - Defined- Wide Area Network) technology. We will try to understand why it is essential to implement the latest technology instead of investing in the existing MPLS (Multi- Protocol label switching) by taking an example of a retail organization. We also have a look at how to evaluate the product by using some metrics and how different teams are involved during different phases of the project.
