Abstract
Voice over Internet Protocol (VOIP) in an efficient manner is a basic requirement of modern era. The real time and non-real traffics demand customized communication provisioning to get guarantee of service. For this we proposed a user fulfillment design for facilitating packets switching in 3G cellular network to insure provisioning of QoS (quality of service) in DiffServ (Differentiated Services) Network. To enhance QoS for real time traffic by reducing delay, packet loss and jitter, we proposed Low latency queuing (LLQ) algorithm. In this paper, we focused on packet scheduling, Diffserv and QoS classes mapping into Universal Mobile telecommunication System (UMTS) classes and buffering. To associate different types of real time multimedia traffic, the QoS provisioning mechanism used different code points of Diffserv. The new idea in LLQ is to map the video and voice traffics against two separate queues and used priority queuing in Low latency queuing for voice traffic. The results got from reproductions shows that proposed calculation meets the QoS prerequisites.
Highlights
In this era, the transmission of voice as a packet over IP network in an optimized way is relatively core research area
The voice traffic using Priority Queue (PQ) scheduler assigned highest level of priority, while least level of priority is specified for background class
We investigated the quality of service for HSDPA real-time traffic and improved the performance of the end to end network
Summary
The transmission of voice as a packet over IP network in an optimized way is relatively core research area. The people are massively turning to VoIP technology because it provides the facility of cost effective and free call. This popularity is demanding the quality of service for real-time voice and video services. The 3G wireless network has the ability to handle different real-time traffic like video, Voice, and other non-real time traffic applications. The ability to provide real-time services with the guaranty of QoS is the main potential of HSDPA [1]. There are two different mechanisms standardized by IETF to provide quality of service in current IP networks, like integrated Services (InterServ) [21] and Diffserv [22].
