原始语种摘要: Abstract(#br)Decoupling of control and data plane in Software Define Networks (SDN) creates significant flexibility in network management. As networks are evolving into a complex multi-domain multi-layer architecture, traffic engineering across multiple domains and layers entails significant challenges for the control plane, especially when each separate administrative domain is not willing to disclose its network topology and resource information. In this paper, we present the first traffic engineering scheme for a multi-domain SDN by using a hierarchical control plane, in which each domain is managed by a local controller, and they are further controlled by a centralized root controller. To preserve the local topology of each domain, we extend the Network Information Base (NIB) into a...
