Network Quality Of Service Program Of Research And Analysis

Traditional Internet doesn't provide Quality of Service guarantees. The network can only provide best effort data delivery service .How to provide Quality of Service guarantees to multimedia application is a hot topic in current network research. This thesis mainly discussed the relevant research about quality of service in network.First this thesis introduces the require of QoS as well as achieves the necessary and control technology of QoS ; Second this thesis analyzes advantage and disadvantage in Integrated Services/Rsvp and Differentiated Services. After these discussions, we'll also put forward tow plans: Bandwidth Broker and resource reservation aggregation architecture and compare tow plans in three aspects: space complexity respond speed and multicast communication . We make a conclusion that the resource reservation aggregation architecture is more future . On basis on it I put forward a plan about campus networks .At the time I realize the mapping from Integrated Service to Differentiated Service and realize in C language. At last we point out the direction of research and development.
