Decision Logic design Clause Samples

Decision Logic design. ‌ The Decision Logic component must make decisions for each individual flow based on the current state of the flow. As previously discussed, the SLA can be considered in two parts; delay and throughput/packet loss rate. The functionality of Decision Logic thereby becomes two-fold. First of all it must evaluate the state of each flow and determine if the flow should be up- or downgraded according to its delay SLA and it must evaluate how desirable a flow is to drop if there is a congestion in the network. Then it must determine if there actually is a congestion in the network and start dropping flows to eliminate the congestion. The design of this logic is presented in the flowchart in figure 4.8.
