Dynamic Bandwidth Management in Distributed VoD based on the User Class Using Agents

TL;DR

This paper introduces a dynamic bandwidth management algorithm for distributed VoD systems that prioritizes higher class users and popular videos, improving QoS, reducing server load, and maximizing bandwidth utilization using agent technology.

Contribution

It presents a novel agent-based algorithm that dynamically allocates bandwidth based on user class and video popularity, enhancing system efficiency and user experience.

Findings

Reduces load on central multimedia server

Maximizes bandwidth utilization

Allocates more bandwidth to higher class users

Abstract

This paper proposes a dynamic bandwidth management algorithm in which more bandwidth is allocated for higher class users and also higher priority is given to the videos with higher popularity within a class using agent technology. The popularity and weight profile of the videos which is used for efficiently allocating bandwidth is periodically updated by a mobile agent. The proposed approach allocates more bandwidth for higher class users and gives higher priority for higher weight videos [popular videos] so that they can be served with high QoS, reduces the load on the central multimedia server and maximizes the channel utilization between the neighboring proxy servers and the central multimedia server and lower video rejection ratio. The simulation results prove the reduction of load on central multimedia server by load sharing among the neighboring proxy servers, maximum bandwidth utilization, and more bandwidth allocation for higher class users.
