The design of QoS guarantee network subsystem
Jun Wen, Lu Xianliang · ACM SIGOPS Operating Systems Review · 2002
The current Internet service model treats all requests equivalently, there are great need of Quality of Service guarantee for real-time traffic. The paper covers two QoS guarantee methods: Integrated Service and Differentiated Service, and discusses its interoperation problems. To estimate the efficient bandwidth of traffic flow requirement, we use Fractional Brownian Motion model to simulate the self-similar traffic. The algorithm can plenty utilize bandwidth. When combining with the user-level network processing and interoperation of Intserv and Diffserv, the new network architecture can have better QoS guarantees. The experiments prove this result.
