Due to the ever-growing network capacity demand, energy-efficient and scalable networking solutions are needed in all networking segments. In this paper, three metropolitan ring architectures are considered and compared for resource and power utilization: Ethernet, Reconfigurable Optical Add-Drop Multiplexers (ROADM), and an optical packet switching (OPS) scheme called Packet Optical Add-Drop Multiplexers (“POADM”), which was recently proposed. Both single and multirate scenarios are investigated. In addition, a novel resource allocation strategy for POADM-based OPS multirate rings is proposed for the first time. We show through simulations that POADM allocates resources very efficiently such that multi-fiber rings can be avoided even for high loads. Results show that OPS with POADM can be up to 2 to 3 times more energy-efficient than competing technologies.

This paper discusses prospects and challenges of optical networking designed to meet exponentially growing demands of data traffic. We discuss both intra and inter data-center networking. For intra-datacenter networking, a single arrayed waveguide grating router based optical switch offers fully connected all-to-all parallel interconnection amongst thousands of racks to achieve high throughput and low-latency interconnection in a new flattened network topology. This new interconnection network named LION provides significant performance advantages over other electrical, optical, or hybrid interconnection networks in terms of available bandwidth per channel, end to end latency and throughput. For inter-datacenter networking, we investigate flexible bandwidth elastic optical networks designed to adaptively accommodate bursty and high capacity traffic between the data centers while supporting the traditional traffic in the background. Further, we demonstrate adaptive and real-time control of the spectral assignment and modulation format for each slice while achieving defragmentation to optimize the spectrum utilization under the dynamically varying traffic demands. The paper covers the intra- and inter- datacenter networking architecture, algorithm, control plane and simulation and experimental studies from the network testbed.

For many years, the convergence of IP data services and transport network services based on optical transmission has been at the heart of carriers' investments and business strategies. However, significant challenges still remain. Over time, the inherent technological differences between the IP and transport networks have deeply segmented their operation, leading to the carrier's organizational fragmentation and segregation of management competencies. Although these two networks are typically deployed in tandem, carriers still lack of tools capable of providing automated coordination of management procedures and orchestration of business practices between them, especially, in multi-vendor deployments. Overall, the separation of management functions between the “IP” and “transport” networks continues to be profound, and remains one of the major impediments hindering the expected convergence of IP and transport network services. To address this challenge, we present a roadmap for convergence from the point of view of network management, and describe an easy-to-deploy solution that can enable interoperation and coordinated actions between the IP and transport management systems already in place in carrier networks. This solution is being prototyped with special attention on multi-vendor network management scenarios.

Current DSL products that provide broadband over copper pair are reaching their capacity limits. In many cases, their peak rate struggle to deliver HDTV video streams, which are widely acknowledged as one of the killer Internet applications in the near future. Fibre-to-the-premises (FTTP) solutions are being deployed to address the problem of scarce capacity in the network access. However, their ability to increase access capacity by over two orders of magnitude could create substantial scalability problems as power consumption of current IP-centric network architectures in the metro and core nodes will scale linearly (or worse) with capacity increase. Long-reach passive optical networks were introduced as a solution to this scalability problem, since they considerably reduce cost and power consumption for network operators, by allowing optical bypass of a large number of metro nodes in the network. In this paper we report the results of a deployment study of a dual-parented protected, nation-wide LR-PON installation for Ireland and the UK, based on real dataset. We focus on further reducing the overall network power consumption by employing a protection mechanism that reduces the IP router capacity required for protection as well as the number of backup OLTs. We show that in a realistic LR-PON deployment up to a 40% reduction in power consumption can be achieved, compared to solutions adopting legacy 1+1 protection. This is accomplished by optimising the network deployment for energy efficient protection, and adopting a smart load balancing technique and a core node architecture that allows N:M protection of backup links.

We are developing an optical packet and circuit integrated network. When a process of lightpath establishment or release fails due to discarding of signaling packets on the network, some nodes are burdened with undesired optical path-connections remaining in themselves. It is possible that our conventional system requires a long time to eliminate such an incomplete lightpath. In this paper, we propose and implement a novel autonomous distributed control for elimination of incomplete lightpaths. In our proposed system, lightpath refreshing messages are generated and transferred by means of the same procedure as signaling. Thereby, when a lightpath establishment or release fails, any nodes can recognize the failures at about the same time because the sender does not transmit lightpath refreshing messages. As a result, the time required to eliminate incomplete lightpaths can be reduced, and furthermore the proposed system is sufficiently robust. Besides, our proposed signaling function is properly interlocked with a dynamic resource-adjustment control, and thus the status of usage of lightpaths in the network can automatically recover.

Recently, researchers have focused their attention in investigating how much energy is consumed within optical Wavelength Division Multiplexed (WDM) networks, as energy requirement is becoming one of the main constraints in their design. Several solutions, typically exploiting optical switching technologies, have been proposed to reduce the excess of optical/ electronic/optical (OEO) signal conversions and electronic processing operations, which are known to be particularly power-hungry. However, most of the studies developed so far provide results that closely related to the specific case-study topologies under consideration, and the resulting conclusions may tend to be topology-dependent. In this paper, we consider a large set of randomly-generated topologies, characterized by different values of the network connectivity index (i.e., a measure of the average number of links per node within the network) and study the influence of this parameter on the energy consumption of different IP-over-WDM network architectures, namely Basic, Transparent and Opaque IP-over-WDM. We aim at quantifying how the the energy consumption of these different IP-over-WDM network architectures depends on network connectivity, geographical dimension and offered traffic.

We present a Virtual Optical Network (VON) Resource Broker and Compositor architecture to dynamically configure and deploy independent instances of virtual GMPLS-controlled WSON. The VON Resource Broker consists of four blocks: resource manager, VON controller, resource allocator and resource configurator. In this paper, we evaluate the impact of the proposed VON Resource Broker on the provisioning of virtual GMPLS control planes and the performance of provisioning lightpaths within a virtual control plane through experimentation in the ADRENALINE Testbed. The obtained results show the trade off between the diminution of blocking rate of VON requests, through the provision of more virtual resources for the virtual control planes, and the deterioration of the virtual control plane performance (e.g. higher setup delay and higher blocking probability while provisioning lightpaths).

We describe a stochastically-based master-slave dual system configuration approach to photonic networking design enabling intrinsic energy-efficiencies to dynamically approach comparable single-device systems that are fully elastic with respect to presented traffic loads. We show analytically that energy-efficiency improvements of more than 90% are statistically possible by adopting a master-slave design configuration. In addition to enabling a lower carbon footprint, our approach allows system switching-speed tolerances to be relaxed, and also improves system reliability as compared with a fully elastic, single-device approach.

A novel Software/Hardware defIned NEtwork (SHINE) framework for future optical network is proposed in this paper. An FPGA based SHINE adaptive network element (SANE) carrying time shared optical network (TSON) service and 10G Ethernet service is implemented. A cross-platform C++/Qt based SHINE IDE incorporating fine/coarse granular instruction set is developed to simply compose node/network manually or automatically. Five types of SHINE working flows, i.e. node on demand, network on demand, node self-adaptation, node generation, and network generation, are depicted, then demonstrated and selectively evaluated. Particularly, a hitless switch-over between sub-wavelength service (TSON) and low latency fat pipe service (10G Ethernet) (network on demand), and a receiver automatically detects transmitter's change (i.e. switch-over from TSON to Ethernet), then adjusts itself (node self-adaption), are highlighted.

In this paper a novel control plane for hybrid optical switching (HOS) networks is proposed. The control plane employs generalized multiprotocol label switching (GMPLS) for configuring the virtual topology, and for establishing and tearing down the label switched paths. The management of the different traffic granularities, including resource reservation and data scheduling, is yielded by the HOS control layer. Furthermore, the architecture of a node that can be managed by the proposed control plane is introduced, and a model for its power consumption evaluation is presented. The power consumption of the considered architecture is then compared with the power consumption of a current IP electronic router. Performance and power consumption of the proposed HOS network are evaluated through the use of an event-driven simulator.
