Thus, the routing controller using the aggregated traffic information calculates the suitable routes without large link utilization by taking into consideration the upper bounds of the link utilization.
However, 2DP routing increases energy usage despite yielding lower link utilization and higher redundancy.
This makes a faster convergence of link utilization in HBDP networks.
In particular, we consider link utilization ratio and path stretch in our algorithms.
The network routers show that peak performance near 100% link utilization is achieved under congestion and combining.
The objective of the WFQ is to assign an effective weight for each flow to enhance link utilization.
Then, we reduced the link utilization immediately after traffic had changed by combining the routing reconfiguration of each layer.
The simulation results show that this scheme can achieve better enforcement of loss probability constraint while maintaining higher link utilization.
Experimental results demonstrate the accuracy of these theoretic models, and the maximum link utilization is decreased by tuning ERMA.
Five design objectives are considered herein, namely, network reliability, network availability, average link utilization, monetary cost, and network delay.
Evaluation on three real topologies shows that R-GR can save energy while satisfying both reliability and link utilization requirements.
