Traffic Models for Data, Voice and Video Sources in Atm
This paper presents an overview of the existing traffic models for data, voice and video sources in ATM. The first paragraph is devoted to bursty traffic of constant throughput, based on classical ON/OFF model. Obviously the superposition of several independent sources gives the method for modelling the variable rate streams. Possible solutions for voice traffic are offered by Markov-Modulated ...
متن کاملmodeling loss data by phase-type distribution
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Upper-level scheduling supporting multimedia traffic in cellular data networks
Wireless data networks such as cdma2000 1x EV-DO and UMTS HSDPA use downlink scheduling that exploits channel fading to increase the system throughput. As future wireless networks will eventually support multimedia and data traffic together, we need a proper criterion for scheduling that can count various service requirements such as delay and packet loss. Although some previous approaches prop...
متن کاملExperimental Results of Traffic Models for Burst Data and Voice Sources in Atm Networks
This paper presents an overview of the existing traffic models for burst data and voice sources in ATM, as well as some experimental results and comments about their implementations. The first paragraph is devoted to burst traffic generated by ON/OFF sources of constant throughput. The Matlab-based scheduler is able to determine the number of ON cells to the number of OFF cells ratio, for every...
متن کاملRegression Video Traffic Models in Broadband Networks
Recently, there has been significant progress towards the deployment of broadband integrated services digital networks capable of flexibly supporting digital video technologies. Digital video such as video on demand, video teleconferencing, video telephony, and broadcast HDTV will constitute a major traffic component of these networks. Statistical analysis and performance modeling of various ty...
