Before revision:  Hence, the main contribution in this paper is enhancing the delay bounds tightness of such networks, through an innovative global analysis based on Network Calculus, accounting the flow serialization phenomena along the flow path . An extensive analysis of such a proposal is conducted herein regarding the accuracy of delay bounds and its impact on the system performance, i. e., scalability and resource-efficiency;
After revision:  Hence, the main contribution in this paper is enhancing the delay bounds tightness of such networks, through an innovative global analysis based on Network Calculus, accounting the flow serialization phenomena along the flow path , by paying the bursts of interfering flows only at the convergence points. The guaranteed endto- end service curves under such a concept have been defined and proved for mono-ring and its impact on the system performance, i. e., scalability and resource-efficiency;
