Intelligent Bandwidth Estimation for Variable Bit Rate Traffic

Abstract

A novel neuro-evolutionary Cartesian genetic programmingbased frame size estimator for multimedia streaming applications has been proposed in this letter. The frame size obtained from the proposed estimator is used to calculate and allocate the bandwidth required for frame transmission. Bandwidth calculation and allocation is done via various probabilistic and linear regression methods. To obtain conclusive results regarding the feasibility of the proposed system, different test case scenarios have been exploited. The bandwidth allocation efficiency for the technique has been compared with previously proposed methods to evaluate its effectiveness in precise bandwidth utilization. Compared to other contemporary techniques, our technique gives approximately 98% efficient frame size prediction and bandwidth allocation.

Implementasi dan Analisis Metode Hierarchical Token Bucket pada Manajemen Bandwidth Jaringan (Studi Kasus : Jaringan Rektorat Institut Shanti Bhuana)

“…e. Packet Loss Packet loss pada QoS merupakan pengukuran jumlah total dari packet yang hilang dalam suatu jaringan. Penyebab terjadinya packet loss adalah banyaknya tabrakan antar packet maupun penurunan packet yang disebabkan oleh habisnya TTL (Time To Live) dalam sebuah jaringan [16].…”

Immense Industrialization And Their Air Prominent Pollutants Effect On Urban Air Quality Index

“…One cannot neglect the effort of government to implement different policies and devise different programs especially for those sectors which are more vulnerable to cause environmental pollution such as energy production particularly from fossil fuels, inception of heavy traffic load to meet the current need and many other harmful residues. Different international organization such as EPA (Environmental Protection Agency) [Khan, 2012] , World Bank, WHO (World Health Organization) [Technology et al, 1984], the European Union Air Quality Frame work and Daughter Directives, put their utmost attempt to establish and promote their own standards for this objective. Different Monitoring bodies play vital role in observing effectiveness of air quality control regulations and ensuring the implementation of air quality standards.…”
