"Banyaknya Jenis layanan yang didukung oleh Asynchronous Transfer Mode (ATM) menyebabkan trafik yang dihasilkan menjadi sangat bursty pada titik dimana proses call admission control dilakukan. Untuk memodelkan trafik tersebut, umumnya digunakan model kedatangan Poisson and 2-State Markov Modulated Poisson Process (MMPP-2). Pada penelitian ini dipelajari karakteristik dari kedua model tersebut berdasarkan tingkat burstiness yang ditinjau dari dua buah pendekatan: pendekatan interarrival times dan pendekatan counting process. Berdasarkan kedua pendekatan tersebut, model kedatangan akan dibandingkan berdasarkan beberapa parameter seperti PMR (Peak to Mean Ration), kuadrat koefisien variasi, Index Dispersion of Count dan parameter Hurst. Dari hasil analisa dan simulasi didapatkan bahwa ternyata model kedatangan MMPP-2 lebih cocok untuk digunakan sebagai model trafik call admission control (CAC) pada jaringan ATM."

"Infrastruktur layanan telekomunikasi pada Fixed Network maupun pada Mobile Network, berevolusi dari jaringan berbasis infrastruktur Switched Circuit Network (SCN) ke jaringan Packet Switch Network (PSN). Pada Packet Switch Network interkoneksi dibangun bersifat Connectionless, menggunakan kanal komunikasi yang digunakan secara bersama (Shared) serta pengelolaan alokasi kanal komunikasi untuk layanan dilakukan dengan menggunakan mekanisme Statistical Multiplexing. Layanan telekomunikasi yang bersifat realtime kurang baik diadopsi pada Packet Switch Network, hal ini adanya kemungkinan Queuing Delay dan Packet Drop yang disebabkan karakteristik dari Statistical Multiplexing. Statistical Multiplexing adalah mekanisme paket forwarding yang menggunakan metode Buffer dan Scheduling dalam meneruskan trafik dari satu network ke network lainnya. Pada tesis ini di rancang dan dikembangkan penerapan manajemen trafik dengan mekanisme berbasis per-flow dengan memanfaatkan infrastruktur switch berbasis SIP untuk mengontrol penerapan kebijakan trafik pada jaringan berbasis paket yang dibangun mengacu pada fungsi arsitektur Policy Based Admission Control yang didefinisikan oleh IETF. Hasil uji coba menunjukan keberhasilan penerapan QoS dengan pengkondisian Throughput layanan jaringan berdasarkan profil pengguna. Metode tanpa umpan balik antara Call Session Control Function (CSCF) dan Decission Point (PDP) memiliki kinerja yang mendekati CSCF umumnya, namun pada skenario ini terjadi perbedaan waktu yang cukup berarti antara penyelesaian waktu pemrosesan SIP Signalling dan penerapan QoS di sisi Policy Enforcement Point (PEP).......Next generation of fixed network and Mobile network telecommunication infrastructure and services is evolved from Switched Circuit Network (SCN) based to Packet Switched Network (PSN) based. Within Packet Switched Network interconnection of communication services is built in a connectionless environtment , using a shared communication channel and adopt a statistical multiplexing mechanism for forwarding traffic between network. Real time communication services is not smoothly adopted by this type of forwarding mechanism because the queuing delay and packet drop characteristic of statistical multiplexing. This thesis implement per-flow traffic basis management by utilizing SIP based softswitch to control the enforcement of traffic policy on a packet network infrastructure that adopt IETF's Policy Based Admission Control architecture. The successfulness of offered solution is obeserved in the distribution condition of allocated bandwidth for VoIP traffic compared to other traffic. The experiments show the successful application of throughput conditioning based on SIP user profiles. The performance issue of SIP signalling is addressed by a no feedback scenario between Call Signalling Control Function (CSCF) and Policy Enforcement Point (PEP) but there is a significant difference of completion time on SIP processing and QoS Enforcement."

"This book presents on the latest research findings, and innovative research methods and development techniques related to the emerging areas of broadband and wireless computing from both theoretical and practical perspectives.Information networking is evolving rapidly with various kinds of networks with different characteristics emerging and being integrated into heterogeneous networks. As a result, a number of interconnection problems can occur at different levels of the communicating entities and communication networks’ hardware and software design. These networks need to manage an increasing usage demand, provide support for a significant number of services, guarantee their QoS, and optimize the network resources.The success of all-IP networking and wireless technology has changed the way of life for people around the world, and the advances in electronic integration and wireless communications will pave the way for access to the wireless networks on the fly. This in turn means that all electronic devices will be able to exchange the information with each other in a ubiquitous way whenever necessary."
