  • Split Control Responsibility in Multi-layer Networks: Who should do what?

    MPLS/SDN World Congress

    Who is responsible for restoring optical connections upon failure? An SDN controller or the distributed control plane of the network? And in the latter case: is the router responsible for initiating the process or is it the optical layer? Attempting to organize these questions according to some general guiding principles and assessing the pros and cons of each approach.

  • In-operation Network Planning

    IEEE Communications Magazine

    Current transport networks are statically configured and managed, because they experience a rather limited traffic dynamicity. As a result, long planning cycles are used to upgrade the network and prepare it for the next planning period. Aimed at guaranteeing that the network can support the forecast traffic and deal with failure scenarios, spare capacity is usually installed, thus increasing network expenditures. Moreover, results from network capacity planning are manually deployed in the…

    Current transport networks are statically configured and managed, because they experience a rather limited traffic dynamicity. As a result, long planning cycles are used to upgrade the network and prepare it for the next planning period. Aimed at guaranteeing that the network can support the forecast traffic and deal with failure scenarios, spare capacity is usually installed, thus increasing network expenditures. Moreover, results from network capacity planning are manually deployed in the network, which limits the network agility. In this article, we propose a control and management architecture to allow the network to be dynamically operated. Employing those dynamicity capabilities, the network can be reconfigured and reoptimized in response to traffic changes in an automatic fashion; hence, the resource over-provisioning can be minimized and overall network costs reduced.

  • Plenary talk about "The Age of Multi-Layer Networking"

    Asia Communications and Photonics Conference (ACP) 2013

    Service provider networks are increasingly challenged by capacity per fiber and cost per bit, yet there is no transmission related innovation in sight that promises to alleviate these bottlenecks in a cost effective manner. We believe that a large part of the problem lies in inefficient over-provisioning of resources to allow the network to cope with traffic forecast uncertainty and failures. Therefore a significant part of the solution is in tight collaboration between the optical layer and IP…

    Service provider networks are increasingly challenged by capacity per fiber and cost per bit, yet there is no transmission related innovation in sight that promises to alleviate these bottlenecks in a cost effective manner. We believe that a large part of the problem lies in inefficient over-provisioning of resources to allow the network to cope with traffic forecast uncertainty and failures. Therefore a significant part of the solution is in tight collaboration between the optical layer and IP layer, allowing for much more efficient use of the available resources at both layers as traffic conditions change. This can be best achieved via a mix of distributed and centralized multi-layer control plane mechanisms.

  • Adaptive Network Manager: Coordinating Operations in Flex-grid Networks

    Transparent Optical Networks (ICTON), 2013 15th International Conference

    Transport networks provide reliable delivery of data between two end points. Today's most advanced transport networks are based on Wavelength Switching Optical Networks (WSON) and offer connections of 10Gbps up to 100Gbps. However, a significant disadvantage of WSON is the rigid bandwidth granularity because only single, large chunks of bandwidth can be assigned matching the available fixed wavelengths resulting in considerable waste of network resources. Elastic Optical Networks (EON) provides…

    Transport networks provide reliable delivery of data between two end points. Today's most advanced transport networks are based on Wavelength Switching Optical Networks (WSON) and offer connections of 10Gbps up to 100Gbps. However, a significant disadvantage of WSON is the rigid bandwidth granularity because only single, large chunks of bandwidth can be assigned matching the available fixed wavelengths resulting in considerable waste of network resources. Elastic Optical Networks (EON) provides spectrum-efficient and scalable transport by introducing flexible granular grooming in the optical frequency domain. EON provides arbitrary contiguous concatenation of optical spectrum that allows creation of custom-sized bandwidth. The allocation is performed according to the traffic volume or user request in a highly spectrum-efficient and scalable manner. The Adaptive Network Manager (ANM) concept appears as a necessity for operators to dynamically configure their infrastructure based on user requirements and network conditions. This work introduces the ANM and defines ANM use cases, and its requirements, and proposes an architecture for ANM that is aligned with solutions being developed by the industry.

  • ACINO (Application-Centric IP/Optical Network Orchestration)

    ACINO is a European R&D project with an application-centric approach applied to transport networks. The ACINO concept aims at transforming capacity into capability. This implies that it is not focused on investigating how more bits can be carried, but on what can be done with the bits already in transit. ACINO proposes the multi-layer application-centric concept to provide knowledge and differentiation, an agile orchestrator for IP and Optical networks to provide dynamicity, and a set of…

    ACINO is a European R&D project with an application-centric approach applied to transport networks. The ACINO concept aims at transforming capacity into capability. This implies that it is not focused on investigating how more bits can be carried, but on what can be done with the bits already in transit. ACINO proposes the multi-layer application-centric concept to provide knowledge and differentiation, an agile orchestrator for IP and Optical networks to provide dynamicity, and a set of primitives to support programmability by establishing a common language between the transport network and the applications. The application-centric innovation provided by ACINO will be demonstrated in a testbed composed of commercial IP routers and optical nodes.
