Penerapan IPTV pada Local Area Network

INTISARIIPTV merupakan protikol internet yang digunakan untuk mengirimkan siaran televisi digital melalui jalur internet. IPTV mengacu pada Protokol Televisi berbasis Internet di mana internet digunakan untuk menyampaikan program siaran langsung TV dan Video atau sesuai permintaan. IPTV adalah sistem di mana layanan televisi digital dikirimkan ke pelanggan melalui teknologi protokol Internet melalui media koneksi broadband atau internet. Dimana siaran televisi digital dapat disaksikan melalui media streaming yang dapat diakses melalui internet dari berbagai jenis perangkat mobile. Karena layanan dikirim melalui koneksi internet maka tentu saja membutuhkan bandwith agar dapat mengakses siaran televisi digital tersebut. Yang sudah tentu akan membutuhkan bandwith yang tidak sedikit karena pada umumnya siaran televisi memakan waktu yang lama. Belum lagi bandwith yang dibutuhkan sesuai dengan kualitas gambar yang digunakan. Semakin baik kualitas gambar maka semakin besar pula bandwith yang digunakan. Oleh karena itu diperlukan sebuah metode bagaimana cara mengakses siaran televisi digital tanpa harus menggunakan bandwith internet yaitu dengan cara akses secara lokal. Untuk melakukan akses secara lokal dibutuhkan mekanisme pendistribusian sinyal satelit yang ditangkap melalui dua protokol yaitu MPEG-TS dan SAT>IP. Dari dua protokol ini nantinya akan dibandingkan mana yang terbaik untuk distribusi siaran televisi digital secara lokal menggunakan standar QoS (Quality of Service) dengan berbagai parameternya..Kata kunci— IPTV, MPEG-TS, SAT>IP, QoS, Tiphon ABSTRACTIPTV is an internet protocol that is used to send digital television broadcasts through the internet. IPTV refers to the Internet-based Television Protocol where the internet is used to deliver live TV and Video programs or on demand. IPTV is a system in which digital television services are sent to customers through Internet protocol technology through a broadband or internet connection media. Where digital television broadcasts can be watched through streaming media that can be accessed via the internet from various types of mobile devices. Because the service is sent via an internet connection, of course, it requires bandwidth to be able to access the digital television broadcasts. Which of course will require a lot of bandwidth because in general television broadcasts take a long time. Not to mention the bandwidth needed in accordance with the quality of images used. The better the image quality, the greater the bandwidth used. Therefore we need a method of how to access digital television broadcasts without having to use internet bandwidth by accessing it locally. To access locally, a mechanism for distributing satellite signals is needed through two protocols, MPEG-TS and SAT> IP. From these two protocols, it will be compared which one is best for the distribution of digital television broadcasts locally using QoS (Quality of Service) standards with various parameters..Keyword— IPTV, MPEG-TS, SAT>IP, QoS, Tiphon.

Improving the Communication Performance in Multi-Agent Systems for Distributed Manufacturing Process Control

The distributed control of complex and dynamic manufacturing systems is a challenging task and the multi-agent system (MAS) becomes a suitable solution due to its flexibility in both distributing and integrating software functionalities across the controlled system. This paper investigates the potentials of improving agent message delivery by enhancing the underlying communication network with IP QoS mechanisms using service differentiation and early congestion avoidance techniques. The extensive simulation experiments demonstrated the effectiveness of our approach in providing small latency, small jitter and improved throughputs in ACL message delivery, whilst without deteriorating other data applications between distributed controllers.

Quality of Service over Heterogeneous Network with MPLS Backbone

Internet growth in recent years has encouraged many new applications to be provided for the end user. However, providing and maintaining high quality of service for these new applications is a challenging matter that is getting the attention of many many researchers nowadays. The QoS challenge is emanating from the diversity of these applications, in term of bandwidth requirements and high sensitivity to delay and delay variation. Three main architectures were proposed by IETF in an effort to make the IP QoS a reality. They are integrated services (Intserv), differentiated services (DiffServ) and multiprotocol label switching (MPLS). Sometimes perceived as competitor, these architectures are in fact complementary developments that approach the QoS challenge from different network perspectives. Thus these approaches can work together in a manner that provides a global QoS within Heterogeneous network. This paper aims to propose and discusses an improved admission control mechanism in order to achieve a global QoS in the HN Network. The proposed mechanism uses MPLS-TE tunnels at the core of Heterogeneous networks to maintain QoS for inter-domain flows and applications.

The Realization of the IP QoS Based on Network Processor

IP network unprecedented develops in the end of the last century and it evolutes to the next generation network. The network service also presents the characteristics of diversification. Thus the traditional real-time services have not already meet people's need. Algorithms proposed in this paper are developed based on network processor IXP2400 and SDK3.1, and observed on advanced router. Measured results show that, ACL processing module realizes filter and classification functions in the QoS model and meet the requirements filter and classification in QoS system.

Pricing Quality of Service in Diffserv IP Networks

In order to reduce costs and make it easier to integrate disparate systems, networked and virtual organizations (NVOs) should adopt open technology standards throughout the entire organization—standard computing architectures, standard networks, and standard application interfaces. The Internet protocol (IP) technology has been foreseen as a basic networking infrastructure that supports communication requirements of NVOs. With the growing demand for the integration of heterogeneous telecommunication services (e.g., voice, data, video and multimedia), there is a strong need for deploying quality of service (QoS) in IP-based networks. Under such circumstances, the flat pricing models that have been satisfying in traditional best-effort Internet so far do not encourage users to make reasonable use of resources. QoS differentiation introduces a clear need for incentives to be offered to users to encourage them to choose the service that is most appropriate for their needs. In commercial networks, this can be most effectively achieved through pricing. Falkner, Devetsikiotis, and Lambadaris (2000) and Da Silva (2000) supplied comprehensive reviews and evaluation of pricing schemes developed during the nineties and mainly related with per-flow IP QoS approaches, such as the integrated services (IntServ) specified by Braden, Clark, and Shenker (1994). Proliferation of the differentiated services framework, since the late 90s posed a number of new issues and resulted in novel proposals for pricing IP QoS and network resources.
