Abstract
Constraining resource provisioning by domain controllers based on resource requirements projected for remotely-originating inter-domain traffic can improve utilization efficiency and link reliability in multi-domain software defined network (SDN) architectures. A domain controller may be required to reserve a portion of inter-domain link capacity for transporting remotely-originating traffic. This may limit the inter-domain link capacity available for transporting locally-originating traffic in a manner that ensures remotely-originating traffic flows have equitable and/or adequate access to resources of inter-domain links. Alternatively, a domain controller may be required to maintain a minimum throughput rate for remotely-originating traffic, which may cause remotely-originating traffic to be prioritized over locally-originating traffic when necessary to maintain the minimum throughput rate. Provisioning constraints can be generated in a centralized or distributed fashion.
