Abstract

Data-intensive high performance, high quality digital media traffic cannot be accommodated on traditional Layer 3 networks. Alternative technologies to transmit this traffic through the network, such as optical multicast, are being investigated. A prototype of an optical multicast service was showcased during the 7th Annual LambdaGrid Workshop celebrated in Prague last September. The prototype used Time Division Multiplexing (TDM) technology as the data plane and Argia (the evolution of UCLP) as the control/service plane. This paper describes the extensions that were done to the Argia Software to provide the Dynamic Optical Multicast Service and shows the results achieved during the Prague demonstration.

As one of the first worldwide initiatives provisioning ICT (Information and Communication Technologies) services entirely based on renewable energy such as solar, wind and hydroelectricity across Canada and around the world, the GreenStar Network (GSN) is developed to dynamically transport user services to be processed in data centers built in proximity to green energy sources, reducing GHG (Greenhouse Gas) emissions of ICT equipments. Regarding the current approach, which focuses mainly in reducing energy consumption at the micro-level through energy efficiency improvements, the overall energy consumption will eventually increase due to the growing demand from new services and users, resulting in an increase in GHG emissions. Based on the cooperation between Mantychore FP7 and the GSN, our approach is, therefore, much broader and more appropriate because it focuses on GHG emission reductions at the macro-level. Whilst energy efficiency techniques are still encouraged at low-end client equipments, the heaviest computing services are dedicated to virtual data centers powered completely by green energy from a large abundant reserve of natural resources, particularly in northern countries.

... Network Programmability: One of the major areas of network innovation over the last decade has been the design and development of capabilities for programming networks, including the dynamic provisioning of lightpaths and virtualization [48], [49]. It has been demonstrated that such programmability can extend to enabling dynamic provisioning for optical multicasting, including to support high-quality, large-volume digital media [50]. Some of the early work in this area was derived from Grid networking activities, which enabled these distributed computing environments to utilize networks as Bfirst class[ resources directly programmable as opposed to external resources that could not be managed [51]. ...

This paper discusses the evolution of optical networks from foundational data transport utilities and infrastructure to true enablers of next-generation services and facilities, specifically diverse rich digital media services, which are being produced, processed, and consumed by an increasingly sophisticated variety of end users. This evolution has been enabled by several major recent advances in optical networking, including the deployment of high-speed optical connections from core networks to enterprise and residential users; the dramatic increase in optical signal speed and reach; and the improvement in control and management planes to support increasingly diverse types of traffic and services. We describe two distinctive areas of broad impact of optical network technologies related to rich media services: high-resolution scientific visualization and high-quality, real-time consumer-driven media production and distribution. Finally, we discuss key trends that may develop next as optical networks further evolve shaped by both rich digital media service requirement and technology innovation.

This paper proposes a new paradigm and strategy for resource management in optical networks considering that resources allocated to a user or service can be squatted in by third parties temporarily in order to provide support for emergency situations or allocate traffic from different priorities that experience a sudden increase of demanded resources in the network. We introduce the strategies of Soft Squatting and Hard Squatting. Moreover, we propose a model and a preliminary evaluation for fibre infrastructure sharing in all-optical networks using the proposed squatting strategies.

Providing QoS for big data applications requires a way to reserve computing and networking resources in advance. Within advance reservation framework, a multi-domain scheduling process is carried out in a top down hierarchical way across multiple hierarchical levels. This ensures that each domain executes intra-domain scheduling algorithm to co-schedule its own computing and networking resources while coordinating the scheduling at the inter-domain level. Within this process, we introduce two algorithms: iterative scheduling algorithm and K-shortest paths algorithm. We conducted a comprehensive performance evaluation study considering several metrics that reflect both grid system and grid user goals. The results demonstrated the advantages of the proposed scheduling process. Moreover, the results highlight the importance of using the iterative scheduling and K-shortest paths algorithms especially for data intensive applications.

Providing interoperability in multi-domain optical grids requires sharing resource information among different domains. Sharing full resource information may not be appropriate due to security and business confidentiality reasons. We propose resource information sharing approach based on information aggregation and abstraction for both computing and networking resources. Information aggregation and abstraction affects the overall accuracy of information representation. This calls for more accurate information abstraction techniques. We propose three abstraction techniques: direct formulas, historical data and real-time measurements. The performance of the proposed information sharing approach and the abstraction techniques is evaluated by studying their impact on scheduling divisible load grid applications. Simulation results highlight the advantages of the proposed approach specially for data intensive applications. By using the proposed abstraction techniques, the same performance could be achieved as using large volumes of exact information.

Large scale national and international experimental research environments are required to advance communication services and supporting network architecture, technology, and infrastructure. Theories and concepts are often explored using simulation and modeling techniques within labs or on small scale testbeds. However, while such testbeds are valuable resources for the research process, these facilities alone cannot provide an appropriate approximation of the real world conditions required to explore ideas at scale. Very large scale global, experimental network research capabilities are required to deeply investigate innovative concepts. For many years, network testbeds were created to address fairly specific, well defined, limited research goals, and they were implemented for fairly short periods. Recently, taking advantage of a number of macro information technology trends, such as virtualization and programmable resources, several network research communities have been developing innovative types of network research environments. Instead of designing traditional network testbeds, research communities are designing large scale, highly flexible distributed platforms that can be used to create many different types of testbeds. Also, rather than creating short term testbeds for limited research objectives, these new environments are being designed as long term persistent resources to support many types of experimental research. This paper describes the motivations for this trend, provides several examples of large scale distributed network research environments based on the Global Lambda Integrated Facility (GLIF) and the StarLight Exchange Facility, including the Global Environment for Network Innovation (GENI), and indicates emerging future trends for these types of environments.

Cloud computing services have recently become a ubiquitous service delivery model, covering a wide range of applications from personal file sharing to being an enterprise data warehouse. Building green data center networks providing cloud computing services is an emerging trend in the Information and Communication Technology (ICT) industry, because of Global Warming and the potential GHG emissions resulting from cloud services. As one of the first worldwide initiatives provisioning ICT services entirely based on renewable energy such as solar, wind and hydroelectricity across Canada and around the world, the GreenStar Network (GSN) was developed to dynamically transport user services to be processed in data centers built in proximity to green energy sources, reducing Greenhouse Gas (GHG) emissions of ICT equipments. Regarding the current approach, which focuses mainly in reducing energy consumption at the micro-level through energy efficiency improvements, the overall energy consumption will eventually increase due to the growing demand from new services and users, resulting in an increase in GHG emissions. Based on the cooperation between Mantychore FP7 and the GSN, our approach is, therefore, much broader and more appropriate because it focuses on GHG emission reductions at the macro-level. This article presents some outcomes of our implementation of such a network model, which spans multiple green nodes in Canada, Europe and the USA. The network provides cloud computing services based on dynamic provision of network slices through relocation of virtual data centers.

During the last years, a trend has emerged at universities, large enterprises, government institutions, hospitals and public institutions towards acquiring and deploying their own dark-fibre or wavelength networks as opposed to purchasing bandwidth network services from the traditional operators. These institutions usually follow the condominium model to build and deploy their network. The parties get together in a joint effort to purchase the network equipment and deploy the dark fibre. Each institution gets a subset of the deployed fibre and part of the available ports, proportional to their initial investment. However, each institution manages their resources independently of the other organisations that share the physical substrate. Traditional control plane architectures cannot address the requirements of this type of networks, because they assume a single entity has administrative control of all the network elements in a physical domain.

Cloud computing is a new model of consuming and delivering IT and infrastructure resources. It enables users to obtain what they need, as they need it, from advanced applications to IT infrastructure and platform services, including virtual infrastructure, servers and storage. It can provide significant economies of scale and greater business agility, while accelerating the pace of innovation. Network virtualization, as a key enabling technology in resource provisioning for cloud, has attracted extensive attention from both academia and industry. It takes cloud services to the next level by delivering optimised resources, on-demand utilisation, flexibility and scalability. This paper proposes a novel architectural solution for future cloud service providers based on the concept of Infrastructure as a Service (IaaS) framework and IP network virtualization. A number of associated schemes have also been designed as building blocks for the proposed framework, including resource description and abstraction mechanisms, virtual network request method and a resource broker mechanism named Marketplace. The proposed framework is able to respond quickly to the infrastructure needs for those cloud services with dynamic resizing of the infrastructure by aggregation or partition to meet capacity requirements of services. At the same time, it improves the utilisation of providers' resources with the creation of an infrastructure incorporating the heterogeneous resources in the data centre. In addition, the proposed marketplace, which also allows the trading of IP network resources between infrastructure providers and cloud service providers, is an important and complementary innovation within the cloud landscape.

Currently, support for digital media is one of the fastest growing requirements of the Internet as demand transitions from services designed to support primarily text and images to those intended also to support rich, high quality streaming multi-media. In response to the need to address this important 21st century communications challenge, an international consortium of network research organizations has established an initiative, the High Performance Digital Media Network (HPDMnet), to investigate key underlying problems, to design potential solutions, to prototype those solutions on a global experimental testbed, and to create an initial set of production services. The HPDMnet service is being designed not only to support general types of digital media but also those based on extremely high resolution, high capacity data streams. These HPDMnet services, which are based on a wide range of advanced architectural concepts at all layers, provide a framework for network middleware that allows non-traditional resources to enable new network services, including those based on dynamically provisioned international lightpaths supported by flexible optical-fiber and optical switching technology. These HPDMnet services have been showcased at major national and international forums, and they are being implemented within several next generation communications exchanges.

This document provides the principles behind the MANTICORE project, whose main goal is to create an innovative service for the Network Operations Centre and end users that allows them to customize the configuration of their own dedicated IP physical and/or logical network through the use of a Web Services based Resource Management System. The motivation and the concept of this logical IP Network Service will be detailed and the software architecture of the first MANTICORE implementation will be explained (this implementation is based on the IaaS Framework, Infrastructure as a Service Framework). The conceptualization of the IP routing (internal and external) is important when providing logical IP networks; thus, the basic ideas will be explained in this paper. Future implementations will be able to extend the concept to layer 0, 1, 2 (by integrating MANTICORE with the Argia and Ether products) and/or layers above layer 3. Some of the MANTICORE future work, like the interoperability with the IPsphere Framework, will be carried out as part of the activities of the FEDERICA FP7 European Project.

Purpose – The purpose of this paper is to illustrate the advantages of using the UCLP software for network operators, advanced and regular end users in the research networking community. Design/methodology/approach – This paper provides an example of the deployment of UCLP in the GÉANT2/National Research and Education Networks (NRENs) scenario, and compares how network operators, advanced users and regular end users would do their work, with and without UCLP. Findings – The paper provides high-level technical information about UCLP as well as depicting the drivers for its use in the European research networking community. Research limitations/implications – This paper does not explain the details of the deployment of the software in the GÉANT2/National Research and Education Networks (NRENs) scenario, it just explains the benefits that the deployment of the software would provide. If the deployment was to be done today, some improvements to UCLP should be done, as well as support for more equipment vendors should be added. Practical implications – UCLP could provide more flexibility to the e-science community if it was deployed over the European research networking infrastructure, because it would isolate network users from each other while providing them an unprecedented degree of control over the network. Originality/value – Nowadays, several control/management solutions for networks exist, but none that is capable of partitioning a physical network into slices and handoff its management to the users, like UCLP does. This is the first UCLP paper that studies a hypothetical deployment of UCLP in the European research networking scenario, and evaluates the drivers and implications of such a deployment.

The layer 1 virtual private network (LlVPN) technology supports multiple user networks over a common carrier transport network. Emerging L1VPN services allow: L1VPNs to be built over multiple carrier networks; L1VPNs to lease or trade resources with each other; and users to reconfigure an L1VPN topology, and add or remove bandwidth. The trend is to offer increased flexibility and provide management functions as close to users as possible, while maintaining proper resource access right control. In this article two aspects of the L1VPN service and management architectures are discussed: management of carrier network partitions for L1VPNs, and L1VPN management by users. We present the carrier network partitioning at the network element (NE) and L1VPN levels. As an example, a transaction language one (TL1) proxy is developed to achieve carrier network partitioning at the NE level. The TL1 proxy is implemented without any modifications to the existing NE management system. On top of the TL1 proxy, a Web services (WS)-based L1VPN management tool is implemented. Carriers use the tool to partition resources at the L1VPN level by assigning resources, together with the WS-based management services for the resources, to L1VPNs. L1VPN administrators use the tool to receive resource partitions from multiple carriers and partner L1VPNs. Further resource partitioning or regrouping can be conducted on the received resources, and leasing or trading resources with partner LlVPNs is supported. These services offer a potential business model for a physical network broker. After the L1VPN administrators compose the use scenarios of resources, and make the use scenarios available to the L1VPN end users as WS, the end users reconfigure the L1VPN without intervention from the administrator. The tool accomplishes LlVPN management by users

This paper describes the world’s first real-time, international transmission of 4K digital cinema and 4K Super High Definition (SHD) digital video at iGrid 2005, hosted at the California Institute of Telecommunications and Information Technology (Calit2) at the University of California, San Diego. Nearly six hours of live and pre-recorded 4K motion picture and audio content was streamed to iGrid in San Diego from the Research Institute for Digital Media and Content (DMC) at Keio University in Tokyo.To implement this demonstration, several new technologies were introduced, including a prototype high-performance 4K compressed multicasting system called “JPEG 2000 Flexcast”, and “Soundscape”, a practical scheme for synchronizing audio and video transmitted from different locations over IP networks.These iGrid 2005 demonstrations proved that it is now feasible to implement networked professional audio/video applications–production, post-production and distribution–even at 4K quality over IP networks up to 15,000 km long. The demonstrations also showed the new 4K motion picture technology being introduced for digital cinema can be usefully applied to other network applications such as remote telepresence, distance learning and scientific visualization.

User controlled LightPaths version 2 provides a network virtualization framework upon which communities of users can build their own services or applications without dealing with the complexities of the underlying network technologies and still can maintain the functionality that the network provides. The system has been designed as a service-oriented architecture where Web services and Web services workflows are the basic building blocks. Articulated private networks are presented as the first services built upon the UCLPv2 network virtualization middleware. APNs can be considered as a next generation VPN where a user can create a complex, multi-domain network topology by binding together network resources, computers, time slices, and virtual or real routing and/or switching nodes. A first implementation of the UCLPv2 software was deployed on CAnet 4, Canada's research and education network, and currently, it is being used by Environment Canada, a federal government department, to enable an APN that links its research facilities across the country.
