Abstract

QoS techniques and transmitted in real-time communication with the advancement of technology a variety of applications and services are available these days, mobile devices bogeuphwa LTE technology to the development of multimedia services with high quality can be realized. In order to satisfy this condition simply with a router with an increased bandwidth expansion by considering the increase in the routing table of the network scalability problems included. Burst traffic data to be distributed according to the environment is to be centered. To do this, the destination -based routing method to transmit the current paper -based (Source routing) routing settings are required. In this paper, published by the IETF, IP switching system based on standardized protocol Label Switching Multi-Protocol Label Switching (MPLS) network by using the existing Best Effect is difficult to guarantee QoS for multimedia transmission in MPLS network environment using optimized QoS guarantees to transmit the multicast.

QoS기술과 전송기술의 고도화로 실시간 통신과 다양한 응용서비스가 가능하며 요즘 모바일기기의 보급화와 LTE기술의 발전으로 멀티미디어 서비스가 고품질 구현이 가능하다. 이러한 조건을 만족시키기 위해서는 단순히 대역폭 확장과 라우터 증가와 라우팅 테이블의 증가를 고려하여 망의 확장성 문제가 포함되어진다. 트래픽 폭주에 따른 데이터를 분산할 수 있는 환경이 중심이 되어야 된다. 그러기 위해서는 현재 수신지 기반 라우팅 방식을 송신지 기반 (Source routing )의 라우팅 설정이 필요하다. 본 논문에서는 IETF에서 발표한 표준화인 IP스위칭 방식 기반의 레이블 스위칭 프로토콜인 Multi-Protocol Label Switching(MPLS)을 이용하여 기존망의 Best Effect로 멀티미디어 전송에 QoS보장이 힘든 환경을 최적화된 MPLS망을 이용 QoS를 보장하여 멀티캐스트를 전송하도록 한다.
