| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 90 === The popularity and usefulness of the Internet have been growing exponentially in the past several years. Provisioning an Internet Service Provider (ISP) backbone network for intra-domain IP traffic is a big challenge. At the same time, it is urgent for ISPs to provide Quality of Service (QoS) to customers for guaranteeing the loss, delay or bandwidth requirement of data transmission. In this thesis, we investigate the exten-sions to the link-state routing protocol for QoS routing (constraint-based link-state routing), the concept of traffic engineering, and the interaction between QoS signaling protocols and constraint-based link-state routing. We adopt a practical viewpoint in a way that mimics the actual structure in a router to propose the constraint-based link-state routing architecture and discuss the general operations within this architec-ture. By incorporating a simple signaling protocol, the complete actions regarding QoS routing in the traffic-engineering domain are better understood.
