SDN's MPLS network offers end-to-end Quality of Service (QoS) capabilities. The charge for this service is in 1 megabit increments. QoS is activated on an individual circuit level. QoS is only active during times of congestion on the circuit. SDN offers 3 queues; Real Time, Mission Critical and Best Effort. SDN will need to know from the customer how the traffic is being marked. The customer markings can be DSCP and/or IP Precedence. SDN will honor these markings and place the traffic into the appropriate queue. SDN collaborates with the customer to determine these markings and what traffic type gets placed into the corresponding queue. SDN also works with the customer on determining the size of each queue.
