A REAL-TIME MULTIMEDIA APPLICATION STUDY IN LMDS NETWORKS USING MPLS

摘要

Son kullanycylar i?in farkly hizmet synyflaryny sa?lamak üzere farkly kablosuz a? ??zümleri geli?tirilmi?tir. Bu ama?la bu teknolojik alanda ATM ve IP teknolojileri ba?aryly olmu?tur. Yerel ?ok Noktaly Da?ytym Sistemi (LMDS) geni? bant kablosuz eri?im (BWA)bir a? ??zümüdür. Bu ?aly?mada ?oklu ortam uygulamalary i?in MPLS üzerinden LMDS a? uygulamasy ger?ekle?tirilmi?tir. LMDS-MPLS a? modeli OPNET 9.0 benzetim paket kullanylarak simüle edilmi? ve ger?ekle?tirilmi?tir. ?e?itli yük durumlarynda ?rnek ses, video, veri ve kritik olmayan veri trafikleri i?in benzetim sonu?lary elde edilmi?tir. U?tan uca gecikme sonu?lary analiz edilmi? ve sunulmu?tur.Several wireless networking solutions have been developed to provide different types of services for various end user applications. Due to the success of ATM and IP technology in the information technology area. Local Multipoint Distribution Service (LMDS) is a broadband wireless access (BWA) networking solution. In this paper, an LMDS (Local Multipoint Distribution System) over MPLS (Multi-Protocol Label Switching) network for real-time multimedia applications is introduced. LMDS-MPLS network model is realized and simulated by using OPNET 9.0 simulation package. The simulation results are obtained for sample voice, video, data and non-critical data traffics under varying network load conditions. Analysis of the end-to-end delay results is also presented.
