With the high volume of traffic in recent network, traffic between the switches has exchanged rapidly among the servers that may conduct the link congestion. In a traditional network, routing protocols are used the shortest path algorithm and congestion will occur in the network links. Equal-Cost Multi-Path (ECMP) algorithm cannot fairly distribute the bandwidth of the links between the flows. These flows suffer long queuing delays and degrades throughput. Flow Collision Avoidance algorithm (FCAA) is an efficient method to alleviate the network congestion by rerouting the flows to guarantee the performance of the network. Congestion occurs when flow demand exceeds link capacity and it leads to the degradation of QoS. The algorithm evaluates the existing flow’s demand based on port statistics to handle the collision of the large flow in the network avoiding the congestion. The evaluations indicate that SDN-based FCAA algorithm enforces the required end-to-end QoS for each traffic flow over ECMP.
