Daneshamand Middledown, NJ, USA Optical networks are currently undergoing several attractive evolutions, ranging from 100G per channel transmission, integrated OTN-based WDM transmission and core switching, and flexible colorless/directionless/gridless ROADM to advanced control plane and management plane technologies. On the other hand, new services such as bandwidth virtualization and VPN impose new challenges to carriers, pushing them to rethink optical network design, planning, control and management issues. In order to support delivery of highly efficient packet services, highly reliable circuit services in emerging optical networks simultaneously, intelligent and automatic optical network design, planning, and control solutions are really important. This special issue features recent and emerging advances in optical networks control and management. Six papers were selected for publication, which cover topics including network reconfiguration control, multi-layer survivability, crosslayer fault-tolerant design, optical network virtualization, optical network real-time monitoring techniques, and network planning and operation tools. - The first article, Forward-Looking WDM Network Reconfiguration with Per-Link Congestion Control, co-authored by Jing Wu, James Zhang, Gregor v. Bochmann and Michel Savoie investigates the reconfigurations of wavelengthrouted WDM networks in response to changes of lightpath demands, with the objective of providing service to more lightpath demands without additional network resources from a long-term network operation point of view. The proposed model allows a natural separation between the operation of the optical layer and the user traffic layer (predominantly the IP-layer. Simulation results show that by properly controlling resource allocations in the current session using their proposed mechanism, greatly reduces the rejections in future sessions. Multi-layer optical protection and restoration is an interesting topic in OTNbased WDM networks. The second article, Multilayer Protection with Availability Guarantees in Optical WDM Networks, co-authored by Massimo Tornatore, Diego Lucerna, Biswanath Mukherjee, Achille Pattavina investigates the problem of survivable dynamic connection provisioning in the mesh backbone networks. Differentiated services where connections may have different availability requirements are assumed, and here protection (if needed) is provisioned based on availability requirements and the current network state. The authors in this article proposed new multilayer routing strategies that perform effective availabilityguaranteed grooming of sub-wavelength connections. These strategies jointly considered connection availability satisfaction and resource optimization and are developed under two different practical hypotheses: guaranteed target, i.e., a connection is routed only if its availability target is satisfied and best-effort target, a connection is always routed and, when the availability target cannot be guaranteed, the path with the best possible availability is provisioned. Numerical results are reported and discussed for the two approaches mentioned above. In both cases, the results show high effectiveness of their provisioning strategy. The third article is about fault tolerant policy design in optical networks, titled Cost Efficient Fault Tolerant Design in Mesh Optical Networks with the Load Aware Method, co-authored by Ruyan Wang, Dapeng Wu, Sheng Huang, Keping Long. The authors designed a set of cost efficient fault tolerant mechanisms. The main objective is the minimization of the total number of required wavelengths. Furthermore, based on the method of the Integer Linear Program (ILP), shared-path protection and shared-link protection strategies are achieved, respectively. Moreover, the objective of minimizing the load imbalance is used to ensure that the network resources are utilized efficiently, and then the wavelength contention can be mitigated by selecting the working path and backup path reasonably. The next one, Adaptive Fault Monitoring in All-Optical Networks Utilizing Real-Time Data Traffic, co-authored by Dong Shen, Kam-Hon Tse and Chun-Kit Chan, proposed a novel fault detection and localization scheme for all-optical networks with the information of real-time data traffic. The studied adaptive fault localization framework is based on combining passive and proactive monitoring solutions, together with adaptive management in two phases. Numerical results indicate that the proposed scheme has good scalability, in terms of the number of fault monitors required. In the fifth one, A Cost Efficient Design of Virtual Infrastructures with Joint Node and Link Mapping, co-authored by Hongfang Yu, Vishal Anand, Chunming Qiao, Hao Di, Xuetao Wei, the authors studied the problem of cost efficient VI mapping and proposed a novel approach called the virtual infrastructure mapping algorithm (VIMA) that jointly considers node mapping and link mapping. Such a close coordination between the link and node mapping stages increases the efficiency of the VIMA algorithm. The authors also compared the performance of the proposed VIMA algorithm with other VI mapping algorithms such as NSVIM, vnmFlib and R-ViNE under various performance metrics using simulation. The simulation results and analysis show that the VIMA algorithm outperforms the other algorithms in terms of both VI mapping costs and path lengths of VI links. The last article, DICONET NPOT: An Impairments Aware Tool for Planning and Managing Dynamic Optical Networks, co-authored by Siamak Azodolmolky, Panagiotis Kokkinos, Marianna Angelou, Emmanouel (Manos) Varvarigos, Ioannis Tomkos, introduced a network planning and operation tool, called NPOT, which supports physical layer impairment-aware network design. The architecture and key building blocks including network description repositories, QoT estimator, IA-RWA engines, component placement algorithms, and failure localization modules were presented as well. More importantly, the authors also gave several experimental results for NPOT, evaluating the performance of its impairment-aware routing and wavelengths assignment engines.
