[0037] figure 1 Through the collection and analysis of traffic, the impact of multiple QoS constraints on traffic scheduling is obtained. The main considerations of multiple QoS constraints include host-to-server delay, traffic proportion, bandwidth percentage, and hop count. A multi-objective optimization function for traffic scheduling is established. Multi-objective optimization is used to design the mathematical model of traffic scheduling. The main goal of traffic scheduling is to make the delay in scheduling the shortest, the flow the most balanced, and the number of hops to be the least.
[0038] For the decision space x=(x 1 ,x 2 ,x 3 ) respectively correspond to (delay, traffic proportion and bandwidth percentage, hops) then the objective function f 1 (x), f 2 (x), f 3 (x) respectively represent the delay function, traffic balance function and hop function in scheduling.
[0039] Record n as the number of network hosts, m as the number of accessible servers, v...
