Dynamic Virtual Network Reconfiguration over SDN Orchestrated Multi-Technology Optical Transport Domains

Application-based Network Operations consists of existing components offering an application-driven network management. We validate its applicability to multi-tenant networks in multi-technology optical domains based on congestion detection and failure recovery by demonstrating fast reconfiguration, while keeping the upper layer unaware.Grant numbers : Spanish MINECO project FARO (TEC2012-38119).© 2015 IEEE.
