  • Description

    Internet is widely deployed almost over the world. However, new transmission technologies and new applications change the patterns of the traffic in the net. Moreover, new users with different profiles can change the patterns of the traffic. The knowledge of the Internet traffic characteristics is necessary to optimize resources, to design the growth of the network, and to know the usage that of the resources. The complexity of the traffic analysis for a network is related to the amount of traffic carried, the topology of the network, the number of users, and the degree of detail desired to the reports. There are other projects working on IP traffic measurement on high-speed networks like CAIDA. The main difference between MIRA and other traffic analysis projects is the need of a full packet capture that implies a lower capture ratio.

    The MIRA platform is mainly divided in two subsystems. The Traffic Capture Subsystem, collects samples of the traffic in a high-speed link. In fact, it is a modification of the OC3MON software for the PCA200 Fore ATM card adapter that provides periodic full IP packet samples. This traffic capture is done in a passive way, which means that it does not interfere the performance of the network. The other subsystem, the Traffic Analysis subsystem has different modules that extract different parameters of the network.

    The results allow us to classify the traffic by application and/or server. As our capture system is not able to capture all the traffic, we get statistical results but correlating the captured data to historic data. A server not detected at one time, if its services persist in the network, will be detected later. A server of an unknown application, with large amount of data generated, will become more important if historic data of that server is accumulated. In that case it will be detected.

  • Description

    The Spanish National Host comprises five organisations offering resources to ACTS projects. Telefonica has an experimental broadband network in Madrid, called RECIBA and this is supplemented by Universities in Madrid and Barcelona who have their own local broadband networks on offer and by the metropolitan area network in Barcelona. The host can offer multimedia conferencing, including multi-point, co-operative working, messaging and video retrieval as well as network connectivity. But, most importantly, the host also allows access to significant user communities that can be used by ACTS projects (or projects from other national or EU programmes) to perform operational trials or experiments of leading edge applications and services that involve real users.

  • Description

    The key goal of the project is to design and implement an intelligent and dynamic DWDM switching all-optical network architecture. This network will be able to provide Bandwidth/Wavelength on Demand with QoS between the different nodes and the IP clients. The network architecture is based on the ASON (Automatically Switching Optical Networks) standard, with intelligent optical cross-connect (OXC) for routing and switching, and optical add-drop nodes. The optical devices will integrate tunable lasers, controlled initially by the Network Manager and later dynamically by the control plane. Thus, the control plane of the network, responsible for setting up, releasing and restoring a connection will be developed under the policies of the GMPLS. The management plane, initially used for establishing the connections and for monitoring all the network topology and equipment status will be implemented with the HP Openview management software.

  • Description

    The purpose of the CATARO project (a coordinated project for the evaluation o optical networks technologies and architectures) is to continue the studies carried out in two previous projects, namely TRIPODE (IP traffic transport over Optical networks: Designing and Evaluation, Ref.: TIC2002-04344-C02) and CARISMA (Connection and access to RedIRIS2 through a multi-channel optical ring, CICYT TIC2000-0304-P4-04). Thereby, the CATARO project consists of two subprojects, namely SENDERO (Designing and Evaluation of optical network architectures Ref.: TEC2005-08051-C3-01) and RINGING (GMPLS/ASON Intelligent Network: Integration of reconfigurable nodes, Ref.: TEC2005-08051-C3-02), which are summarized next.

    The SENDERO subproject basically concerns the analysis aspects, design and performance evaluation of the network architectures based on optical technology having as objectives, on the one hand completing the subjects opened after finalization the TRIPODE project and on the other hand opening new topics, which interest is growing. Particularly, with respect to optical network architectures that could potentially be implemented in a short-term, it will continue working on control plane and routing algorithms for ASON (Automatically Switched Optical Networks) as well as will begin new topics like provisioning of new telecommunication services, which is required by emerging applications like “Grid Computing” and “Storage Area Networks and inter-working the RPR (Resilience Packet Rings) with ASON networks. Regarding mediumterm architectures, the subproject will continue the subject of metropolitan area optical networks taking into consideration possible implementations of the first prototypes in public infrastructures and evaluation of the architectures more sophisticated. However, the principal objective of this block will be centred on the optical burst switching networks (OBS), the architecture which is gaining interest thanks to its both foreseeable strong benefits and future technological affordability. Finally, in the context of long-term network architectures, the subproject will continue the study on OPS (Optical Packet Switching) nodes functionality with a focus on QoS provisioning, moreover it will approach a study in scope of the whole network, particularly, focusing on a design of the control plane for OMPLS (Optical MPLS) networks, as well as in evaluation of the routing algorithms. At last, we will begin a new topic that consists of an adaptation the technique of optical packets commutation for designing the architectures for high performance computers.

    The RINGING subproject concerns the design and building of a reconfigurable optical node with an advanced design, and its further integration into a real network to develop a field trial. The main objective of this subproject is the integration of reconfigurable optical nodes in the GMPL/ASON network, which has been obtained as a result of the CARISMA project. Thanks to the participation in TRIPODE, CARISMA, and FIRM (Field trial with Integrated ROADMs and GMPLS compliance, the CELTIC-EUREKA-2004 project, www.celtic-iniciative.org) projects, the know-how necessary for the implementation of the reconfigurable optical nodes is ready. The subproject is divided in two main blocks. The first one will be dedicated to building reconfigurable optical nodes, while in the other, the aspects of the integration of these nodes in an optical network which was constructed during the CARISMA project, will be treated. Introduction of the traffic engineering (TE) techniques into GMPLS/ASON networks, which will result in a network able to provide optical virtual private networks (OVPN) as well as suitable for working in a GRID environment of great importance in the next future, should be highlighted among the most important general objectives of this subproject. For the development of these last objectives also the participation in PROMISE (Provisioning and monitoring of optical services, CELTIC-EUREKA-2004 project) project will be useful.

  • Description

    Internet, considered as a system, has experienced an unforeseen growth and many local solutions (new applications and protocols and protocol enhancements) have been added. Each solution or protocol intends to solve a problem but independently of other enhancements and protocols. Each of the technologies has been designed as a standalone process not taking into account the inter-dependencies with other ones. Thus, despite the system is flexible enough scalability and performance issues are pushing it to its limits. The main goal of this project is to contribute in the design of technologies for a converged and pervasive Internet. The project aims to push new services and protocols into the network considering them as coupled processes. To do that, we will take into consideration four of the most relevant aspects that are currently of interest of the research community in this field. These are the optical transport, the ubiquitous connectivity, the application of a traffic analysis and monitoring techniques for the management and control of the network, and the security of communications. In order to address these aspects the project is structured in the following research activities: Architectures for the Pervasive Networking, Traffic monitoring and analysis, Converged Optical Networking Infrastructure, and Digital Identity and Electronic Signature, which coincide with of the different subareas of expertise of the Broadband Communication Systems research group that traditionally have exploited participating in separated projects. In this way, an additional benefit of the project will be the integration of these subareas increasing the consistence of the group.

  • Description

    Mobility is unnatural to today’s Internet architecture, primarily due to overloaded IP address semantics. Several schemes address this issue by decoupling the location of an endpoint from its identity. Such location/identity separation inherently provides services fundamental to the future Internet including seamless mobility, multihoming, and traffic engineering. Of the various location/identity separation schemes, the Location/ID Separation Protocol (LISP) (proposed by Cisco Systems Inc., and under standardization at IETF) has a unique position: LISP is incrementally deployable, it does not require changes to transport/application implementations, and it is already under active deployment (see http://www.lisp4.net). Basically, LISP proposes two different types of addresses: Endpoint Identifiers (EIDs) and Routing Locators (RLOCs). EIDs identify hosts, and are assigned independently of the network topology while RLOCs identify network attachment points, and are used for routing. This allows EIDs to remain unchanged even if a topological change, such as a handover, occurs. Thus, LISP’s innate support for location/identity separation makes LISP well suited for mobility. Indeed, the LISP mobility protocol (LISP-MN) has been recently proposed. LISP-MN offers many advantages in front of traditional mobility schemes such as Mobile IP. On the one hand LISP´s separation of control and data planes avoids mobility provider lock-in, and LISP-MN clients can freely roam among providers (usually ISPs). On the other hand, LISP-MN provides native support for multihoming, load balancing and route optimization, this are important aspects for the future mobile clients. However and traditionally, the Internet architecture has evolved independently of cellular networks (3GPP). Nowadays these cellular networks are converging to an all-IP network, and their new architecture must be gracefully accommodated in the future Internet architecture. This imposes a set of important challenges. In this context, we expect that LISP-MN will play a crucial role. LISP-MN provides a higher level of mobility (at the network layer) and mobile clients can freely roam across providers. The main objectives of the NAME project are (i) Research coherent architectures for the future converged cellular and Internet networks and (ii) Research and design advanced services such as content distribution and live streaming for LISP-MN.

  • Description

    Network monitoring is of paramount importance to both network operators and researchers, to the point that it has recently become a major research area. However, network monitoring still suffers from fundamental problems that leave its rigorousness behind more traditional research fields, such as other experimental disciplines within physics or biology. Most scientific works in the field of network monitoring are evaluated using private, undisclosed data sets. Nevertheless, disclosure of experimental data is a basic principle of the scientific method that enables experiment reproducibility, independent validation and cross-comparison of research results. For this reason, we think that the credibility of research works in this area overly relies on the scientific community bona fide. Our initial hypothesis is that two fundamental barriers have to be overcome in order to increase the rigorousness of this scientific area. First, the mere acquisition of reference data sets is extremely challenging from a technological viewpoint due to the ever-increasing network speeds. Second, sociological reasons discourage their publication, primarily due to privacy concerns. Both the technological and sociological barriers are currently perceived to be insurmountable, which prevents the use of common data sets in scientific works and impedes experiment reproducibility. The main objective of this project is to investigate the fundamental research challenges associated to these two barriers. On the one hand, this project will explore novel network monitoring and traffic measurement techniques in order to address the technological difficulties. Main topics of research in this direction will include complex resource management techniques, such as load shedding and distribution, traffic sampling and specialized streaming algorithms for traffic processing and analysis. On the other hand, this project will propose a novel data sharing paradigm that overcomes the sociological barriers. The research carried out in this project will result in a completely novel evaluation framework for network monitoring research based on what we call the “code-to-the-data” model. This model will enable reproducibility, validation and comparison of scientific works without requiring full disclosure of traffic data sets, thus avoiding most privacy concerns involved in dataset publication. Ultimately, the new monitoring and data sharing paradigm resulting from this project will provide a realistic solution to set the use of common data sets as a standard requirement for scientific publication, as it is in other research areas.
