Book excerpt: Optical transport networks based on wavelength division multiplexing (WDM) are considered to be the most appropriate choice for future Internet backbone. On the other hand, future DOE networks are expected to have the ability to dynamically provision on-demand survivable services to suit the needs of various high performance scientific applications and remote collaboration. Since a failure in aWDMnetwork such as a cable cut may result in a tremendous amount of data loss, efficient protection of data transport in WDM networks is therefore essential. As the backbone network is moving towards GMPLS/WDM optical networks, the unique requirement to support DOE's science mission results in challenging issues that are not directly addressed by existing networking techniques and methodologies. The objectives of this project were to develop cost effective protection and restoration mechanisms based on dedicated path, shared path, preconfigured cycle (p-cycle), and so on, to deal with single failure, dual failure, and shared risk link group (SRLG) failure, under different traffic and resource requirement models; to devise efficient service provisioning algorithms that deal with application specific network resource requirements for both unicast and multicast; to study various aspects of traffic grooming in WDM ring and mesh networks to derive cost effective solutions while meeting application resource and QoS requirements; to design various diverse routing and multi-constrained routing algorithms, considering different traffic models and failure models, for protection and restoration, as well as for service provisioning; to propose and study new optical burst switched architectures and mechanisms for effectively supporting dynamic services; and to integrate research with graduate and undergraduate education. All objectives have been successfully met. This report summarizes the major accomplishments of this project. The impact of the project manifests in many aspects: First, the project addressed many essential problems that arisen in current and future WDM optical networks, and provided a host of innovative solutions though there was no invention or patent filing. This project resulted in more than 2 dozens publications in major journals and conferences (including papers in IEEE Transactions and journals, as well as a book chapter). Our publications have been cited by many peer researchers. In particular, one of our conference papers was nominated for the best paper award of IEEE/Create-Net Broadnets (International Conference on Broadband Communications, Networks, and Systems) 2006. Second, the results and solutions of this project were well received by DOE Labs where presentations were given by the PI. We hope to continue the collaboration with DOE Labs in the future. Third, the project was the first to propose and extensively study multicast traffic grooming, new traffic models such as sliding scheduled traffic model and scheduled traffic model. Our research has sparkled a flurry of recent studies and publications by the research community in these areas. Fourth, the project has benefited a diverse population of students by motivating, engaging, enhancing their learning and skills. The project has been conducted in a manner conducive to the training of students both at graduate and undergraduate levels. As a result, one Ph. D., Dr. Abdur Billah, was graduated. Another Ph. D. student, Tianjian Li, will graduate in January 2007. In addition, four MS students were graduated. One undergraduate student, Jeffrey Alan Shininger, completed his university honors project. Fifth, thanks to the support of this ECPI project, the PI has obtained additional funding from the National Science Foundation, the Air Force Research Lab, and other sources. A few other proposals are pending. Finally, this project has also significantly impacted the curricula and resulted in the enhancement of courses at the graduate and undergraduate levels, therefore strengthening the bond between research and education.

Book excerpt: This dissertation focuses on architecting survivable network designs and developing new bandwidth-allocation mechanisms as an integral part of the network's daily operations to better survive major network failures. This is an important topic since telecommunication networks are exposed to many threats such as malicious attacks, equipment failures, human errors (e.g., misconfigurations), and large-scale disasters, both human-made (e.g., due to weapons of mass destruction (WMD) attacks) and natural. Also, the emergence of bandwidth-hungry applications has led to rapid growth in the volume of the data traffic in our networks, and failures (especially a large-scale disaster) result in huge data loss/service disruption in these networks. To alleviate the detrimental effects of failures on network services, the following two aspects need close attention: i) survivable network design and ii) survivable network operation. To improve the network performance under failure mode of operation in a cost-effective manner, this dissertation focuses on architecting survivable network designs and providing intelligent ways of allocating network resources during network operation for better survivability. Today’s networks support diverse services: from cloud-based services (e.g., video streaming) to traditional ones (e.g., VoIP), which have different requirements (e.g., delay/latency tolerance and bandwidth) and characteristics (e.g., origination, importance, and revenue generation). With such heterogeneity, using the same traffic engineering policies (routing, protection, restoration strategies, etc.) for all services can result in suboptimal solutions. In the first part of the dissertation (Chapters 2 and 3), we focus on cost-effective and survivable service provisioning schemes exploiting service heterogeneity, especially degraded-service tolerance, which exploits a service’s capability to operate with reduced bandwidth. We propose two novel disaster-aware service-provisioning schemes: i) the first one combines degraded-service tolerance with the fact that cloud-based services do not require one-to-one connectivity (unicast), and multiplexes cloud-based services over multiple paths destined to multiple servers/datacenters with manycasting and ii) the second one proposes to reallocate scarce network resources after a failure based on degraded-service tolerance of connections. Both schemes maintain some bandwidth (i.e., degraded service) after a failure vs. no service at all. In the second part of the dissertation (Chapters 4 and 5), we shift our focus to improve Software-Defined Network survivability by designing the control plane to be resilient enough to survive network failures whenever possible and to be quickly recoverable at other times. To this end, we propose to design the control plane as a virtual network and map the controllers over the physical network such that the connectivity among the controllers (controller-to-controller) and between the switches to the controllers (switch-to- controllers) is not compromised by physical infrastructure failures caused by disasters. Also, we propose a novel switch-to-controller assignment and communication path routing scheme which prepares for restoration after failures to minimize the recovery time of disrupted switch-to-controller paths, so that the disrupted data traffic can be recovered quickly.
