    Traditional Internet routing is simple, scalable and robust, but cannot provide perfect QoS support due to the current completely distributed hop-by-hop routing architecture. Software defined networking (SDN) opens up the door to traffic engineering innovation and makes possible QoS routing with a broader picture of overall network resources. We further argue that SDN can provide more opportunity for the network users to make their own routing selections with network programmability. In this paper, we propose OpenMCR, a general framework for network users to make their own choice of routing given various requirements. OpenMCR provides routing subject to several additive QoS constraints, which is NP-hard when the number of constraints is two or more. By composing various necessary conditions with different path extension schemes, our platform can customize routing solutions for each network user based on their own requirements. Through experiments in an SDN emulated environment, we evaluate multiple aspects of OpenMCR, demonstrate its effectiveness compared with several baselines and validate our theoretical analysis.
