Abstract

IP QoS is not required to overcome the limitations of the existing Best Effort Service to connect to the explosion of the Internet traffic revenue. To IP QoS requirements of next-generation communication network, Metric Sizing Methodology is very important. However, IP networks have been developed with a focus gender flexibility and scalability than the QoS. Therefore, it is necessary to secure the quality measures for different existing IP technology to apply QoS in IP networks. When establishing the connection quality and transmission quality, based on the IP QoS(Quality of Service) objective data quality metrics can be obtained by analyzing the communication quality hindrance. Understanding the communication quality level may evaluate quality sensitive area and quality hindrance. Establish effective quality metrics can be expected to promote effective and customer satisfaction through improved quality, improved call quality for this issue.

IP QoS는 인터넷 트래픽의 폭증을 수익으로 연결시키기 위해 기존의 Best Effort Service의 한계를 극복하는 것이 필수이다. 차세대 통신망의 필수요건으로 IP QoS는 매우 중요하다. 그러나, IP망은 QoS 보다는 유연성과 확장성에 초점을 맞추어 발전해왔다. 따라서, IP망에 QoS를 적용하기 위해 기존 IP 기술에 여러가지 품질확보를 위한 조치가 필요하다. 접속품질과 전송품질을 기반으로 한 IP QoS(Quality of Service) 품질 메트릭스를 정립 한다면 통신품질 저해요인을 분석하여 객관적인 자료를 얻을 수 있다. 통신품질 수준을 파악하면 품질 취약지역 및 품질 저해요인을 분석할 수 있다. 효율적인 품질 메트릭스 정립은 문제점에 대한 품질개선으로 통화품질 향상을 통한 고객 만족도를 증진효과를 기대할 수 있다.
