ALGORITHM OF BANDWIDTH DISTRIBUTION OF A LOGICAL CHANNEL OF A MULTI-SERVICE COMMUNICATION NETWORK, TAKING INTO ACCOUNT INSUFFICIENT OBSERVABILITY OF A RESOURCE PROVIDED BY A COMMUNICATION OPERATOR

В работе предложен алгоритм распределения полосы пропускания логического канала мультисервисной сети связи, позволяющий повысить качество обслуживания для отдельных сервисов в условиях, когда арендуемый у оператора связи ресурс пропускной способности характеризуется недостаточной наблюдаемостью и отсутствует обмен метками QoS на транспортном уровне. The paper proposes algorithm of bandwidth distribution of a logical channel of a multiservice communication network, which makes it possible to improve the quality of service for individual services in conditions when the bandwidth resource leased from a telecom operator is characterized by insufficient observability and there is no exchange of QoS tags at the transport level.

Priority-Based Bandwidth Management in Virtualized Software-Defined Networks

In Industrial Internet of Things (IoT) applications, when the network size increases and different types of flows share the bandwidth, the demand for flexible and efficient management of the communication network is compelling. In these scenarios, under varying workload and flow priorities, the combined use of Software-Defined Networking (SDN) and Network Virtualization (NV) is a promising solution, as such techniques allow to reduce the network management complexity. This work presents the PrioSDN Resource Manager (PrioSDN_RM), a resource management mechanism based on admission control for virtualized SDN-based networks. The proposed combination imposes bounds on the resource utilization for the virtual slices, which therefore share the network links, while maintaining isolation from each other. The presented approach exploits a priority-based runtime bandwidth distribution mechanism to dynamically react to load changes (e.g., due to alarms). The paper describes the design of the approach and provides experimental results obtained on a real testbed.

Robust Feedback Control for Nonminimum Phase, Delayed, or Unstable Systems with Multiple Inputs

This paper presents a feedback control solution that achieves robust stability and disturbance rejection in systems with multiple manipulated inputs and a single measurable output. The uncertain plant models may exhibit either nonminimum phase, or delay, or unstable phenomena, which makes it not easy to take full advantage of the frequency response of each plant. In the framework of quantitative feedback theory (QFT), a methodology is proposed to decide the best control bandwidth distribution among inputs and to design the set of parallel controllers with as small as possible gain at each frequency. The temperature regulation in a continuous stirred-tank reactor (CSTR) illustrates the benefits of a quantitative frequency distribution of the dynamic controllability between the jacket flow and the feed flow. The main challenge is that the feed flow exhibits a higher temperature regulation capacity and also produces a temporary decrease in the reactor temperature (nonminimum phase behaviour).

Implementasi Load Balancing dan Failover to Device Mikrotik Router Menggunakan Metode NTH (Studi Kasus: PT.GO-JEK Indonesia)

<p class="Judul2"><span lang="IN"> </span></p><p class="Abstrak"><span lang="IN">Perkembangan jaringan komputer dan internet yang begitu pesat pada sekarang khususnya internet sebagai media informasi tentunya harus memiliki kualitas koneksi yang baik. Begitu juga yang terdapat pada PT.Gojek Indonesia yang telah memakai dua ISP (internet service provider). Saat banyak permintaan dari pemakai maka perangkat jaringan akan terbebani karena harus melakukan banyak proses pelayanan terhadap permintaan dari pengguna. Solusinya adalah dengan membagi beban trafik yang datang ke perangkat jaringan, jadi tidak berpusat ke salah satu ISP agar trafik dapat berjalan optimal, memaksimalkan throughput, memperkecil waktu tanggap dan menghindari overload pada salah satu jalur koneksi, teknologi itulah yang disebut Load balancing. Untuk diterapkan teknik Load balancing yang bisa mendistribusi beban kepada sebuah service yang ada pada server dengan memanfaatkan metode distribusi dua line koneksi yang disebut dengan metode NTH. Nantinya mikrotik diharapkan mampu mengoptimalkan bandwidth pada tiap client yang akan koneksi ke internet. Akan diterapkan juga Teknik failover pada jaringan ini, yaitu jika salah satu koneksi gateway sedang terputus maka gateway yang lainnya otomatis akan menopang semua traffic jaringan. Akan dibuat juga menejemen bandwith disemua client, agar pendistribusian bandwith merata.</span></p><p class="Abstrak"> </p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p><em>The development of computer networks and internet so rapidly at the present time, particularly on the Internet as information media of course must have good connection quality. So also found on the PT.Gojek Indonesian who has used two ISP. When many requests from users, the network devices will be burdened because they have to do a lot of service processes for requests from users. The solution is to divide the traffic load that comes to network devices, so that it is not centered on one ISP so that traffic can run optimally, maximize throughput, minimize response time and avoid overloading one of the connection lines, that technology is called Load balancing. Load balancing techniques are applied to distribute the load against a service that is on the server by utilizing the two connection path distribution method called the Nth method. Later, the proxy hopes to be able to optimize the bandwidth for each client that will connect to the internet. Will also be implemented failover technique on this network, that is if one of the gateway connections is being interrupted then the other gateway will automatically support all network traffic. Will also create bandwidth management for all clients, so that bandwidth distribution is evenly distributed.</em></p><p class="Abstrak"><em><strong><br /></strong></em></p>

Bandwidth Distribution Algorithm of Applications in LTE-Femtocell Network

The wireless communication has become the essential of today’s Internet of Things (IoT) and mobile applications which is increasing exponentially in near future. These applications demand high data rate to speed up the communication among IoT or internet applications. The data rate requirement of individual application is different. To fulfill these demands of every application Long Term Evolution (LTE) integrated with femtocell technology is identified as suitable wireless technology. The running applications on a user equipment changes dynamically. Hence in dense deployment of femtocell and IoT devices, the bandwidth distribution to many active applications becomes more complicated. For multiple running applications per device with available bandwidth constraint, optimal bandwidth allocation to applications has become the most challenging issue. We include the bandwidth allocation to applications during handover of user equipment in LTE-femtocell network. The handover procedure needs efficient cell selection criteria for target cell selection. Hence in our research we focus on bandwidth distribution among applications by proposing “Efficient Bandwidth Distribution” (EBD) mechanism and efficient cell selection by “Dynamic Cell Selection” (DCS) mechanisms to mitigate above mentioned issues.

Analisis Penerapan Metode Antrian Hirarchical Token Bucket untuk Management Bandwidth Jaringan Internet

Internet is one of the needs of the community, especially among education and academics such as universities. The high level of internet users is not comparable with the facilities owned by an agency, this makes the internet network manager in Higher Education feel difficult. The cause of the problem that is always a problem is the speed and internet connection is always disjointed, resulting in the slow loading process data while browsing, both at the time of download and at the time of upload. To make internet users in campus area balanced and stable then need bandwidth management based on traffic usage of internet path better. Bandwidth management that can stabilize traffic lanes and equal bandwidth distribution, it can use bandwidth management by Hierarchical Token Bucket (HTB) method. The calculation result in HTB method testing through file download, the average value obtained by TIPHON category standard for throughtput value index is 2 with "Medium" category, delay parameter index is 4 with "Very Good" category, jitter parameter index is 3 with the "Good" category and the packet loss parameter index is 4 with the "Very Good" category.
