"The business of telecommunications is currently undergoing a period of change driven by changes in regulation, increasing demands for services and the development of new access technologies. The market structure of telecommunications is evolving rapidly as new players entering the market and existing players strive to complete in an increasingly volatile market. Moreover the advent of new data services is placing greater demands on the network as operators strive to offer new broadband services.Underpinning much of this change is the access technology itself, both in the transitional form of copper twisted pairs, but increasing through the use of new fibre, radio and copper systems. Indeed the dominant cost of most telecommunication network is the access network itself and typically can demand up to 80% of the total investment required.The book presents an overview of the access network and discusses the technologies that are available. It begins with an introductory chapter defining terms and technologies and goes on to discuss each technology in turn, not only from a technology viewpoint but with a view on how it might be best deployed. Chapters are also included on planning systems and network management, a key aspect of the technology."

"PT CNAF merupakan salah satu perusahaan pembiayaan otomotif dibawah PT CIMB Niaga Tbk. Dalam rangka pencapaian visinya, perusahaan dituntut agar dapat memberikan pelayanan yang cepat, mudah, dan aman kepada konsumen, melalui penyelenggaraan kegiatan operasional yang baik. Pemanfaatan sistem informasi dan teknologi informasi sebagai sarana pendukung pada lingkup internal perusahaan, dapat membantu terciptanya terselenggaranya kegiatan operasional yang baik. Berkaitan dengan hal tersebut, dalam penyediaan sistem informasi perlu ditunjang dengan ketersediaan infrastruktur teknologi informasi yang handal. Salah satu aspek yang sangat penting dalam penyediaan sistem informasi tersebut adalah ketersediaan layanan jaringan komputer. Masalah yang sering dihadapi adalah terjadinya downtime pada jaringan komputer terutama pada jaringan WAN (Wide Area Network). Kondisi geografis tiap kantor cabang, keandalan komponen jaringan, dampak aktivitas pembangunan prasarana, catu daya listrik, dan faktor cuaca sering kali menimbulkan berbagai permasalahan sulit pada layanan jaringan. Hilangnya ketersediaan pada layanan jaringan akan berdampak pada terhentinya penggunaan sistem informasi.Untuk mengatasi masalah tersebut dan sebagai upaya meningkatkan ketersediaan layanan, diterapkan manajemen ketersediaan pada layanan jaringan. Penelitian ini menggunakan kerangka kerja ITIL Ver. 3 sebagai panduan untuk manajemen ketersediaan. Langkah-langkah yang dilakukan melibatkan reactive activities dan proactive activities yang merupakan kunci utama dalam proses manajemen ketersediaan. Hasil yang diharapkan dari rancangan/ penerapan sistem manajemen ketersediaan ini dapat meminimalisasi resiko ketersediaan, mempersingkat waktu downtime layanan jaringan, dan membantu dalam memastikan tingkat ketersediaan layanan yang diberikan sesuai atau melebihi kebutuhan bisnis yang telah disepakati saat ini dan masa depan dengan biaya yang efektif.

PT CIMB Niaga Auto Finance is the premiere automotive finance company under PT Bank CIMB Niaga Tbk. In order to achieve the vision, the company is required to provide their services easily, quickly and safely to the consumers, through the implementation of good operational activities. The use of information systems and information technology as a support tools for the internal company, can help to create a good implementation of operational activities. In this regard, the provision of information systems needs to be supported by the availability of reliable information technology infrastructure.

One of very important aspect in the provision of the information system is a computer network service availability. The problems that often occured is the downtime on computer networks, especially in the WAN (Wide Area Network). The geographical conditions of each branch office, the reliability of network components, the impact of infrastructure development activities, electrical power supply, and weather conditions often lead to complicated problems in network services. The loss of availability of the network services have an impact on the cessation of the use of information systems.

To overcome these problems, and as an effort to increase the availability of services, conducted availability management implementation on network services. This study uses the ITIL framework Ver. 3 as a guide to availability management. The performed activities involving reactive and proactive activities that the key element in the management process availability. The expected result of the design / implementation of the availability management system can minimize the risk of availability, shorten the downtime of network services, and assist in ensuring the availability of services provided meet or exceed agreed business needs of current and future cost-effective manner."

"Penelitian ini membahas modifikasi algoritma link state routing pada jaringan komputer. Jaringan komputer dalam hal ini direpresentasikan dalam bentuk graf. Algoritma link state routing yang biasa dipakai adalah algoritma yang menghasilkan tabel routing dengan menggunakan algoritma Dijkstra dalam menemukan lintasan terpendek. Pada modifikasi algoritma link state routing, sebelum digunakan algoritma Dijkstra, graf dikelompokkan terlebih dahulu dengan menggunakan MST clustering, yang dalam membentuk cluster menggunakan algoritma Zahn. Pada modifikasi algoritma link state routing ini, entri dari tabel routing berkurang, sehingga proses di router menjadi lebih cepat.

This research is about modification of link state routing algorithm on computer network. Computer network in this case is represented as graph. The link state routing algorithm that usual to be used is algorithm that produces routing table by using Dijkstra?s algorithm in finding shortest path. In modification of link state routing algorithm, before using Dijkstra?s algorithm, graph is grouped formerly by using MST clustering, which in forming cluster using Zahn?s algorithm. In this modification of link state routing algorithm, routing table entries reduce, so process in router becomes faster."
