  • Stress of 10G interconnection link (Networking) [achieved]
    Description: The goal of this experiment is to stress the 10 GbE links of Grid'5000. The experiments involved two sites in a time. We create TCP flows between 9 to 13 nodes on each cluster choosen among azur, parasol, grillon. We mesurate the average obtained bandwith. The experiments are running from 5 min to 1 hour.
    Results: At the 22th of August 11:47 to 12:47, we obtain an average bandwith of 8,7 Gb/s with 1 hour experiment. The maximum bandwith was 9.399 Gb/s. We used default configuration i.e. kernel 2.6.12 with Bic TCP stack.
    We can't obtain such results with azur due to network topology on this site.

    We have shown that performance communications in grid (and also in Grid'5000) are mainly based on TCP performance, that's why we need to tune TCP parameters for Grid'5000 as described in our research report. This parameters have been implemented now on each site and Grid'5000 users can use maximum bandwith between sites.

  • Transfert time of large files over Grid5000 (Networking) [achieved]
    Description: In this experiment, we perform mem-to-mem transfert of large files (typically 30Go) simultaneously over 1Gbps and 10Gbps links in Grid5000 in order to assess the impact of several parameters on the predictability and reliability of the maximal completion time of these transferts.
    We are studying several parameters along:
    - congestion level ( 0 to 100%, 1 to 20 flows)
    - starting time (0 to 5s)
    - background trafic (CBR, VBR poisson pareto, vbul...)
    - reverse traffic level (0% to 100%)
    - parallel flows (1, 5 or 10)

  • Investigation of Ethernet switches behavior in presence of contending flows at very high-speed (Networking) [achieved]
    Description: This work examines the interactions between layer 2 (Ethernet) switches and TCP in high bandwidth delay product networks. First, the behavior of a range of Ethernet switches when two long lived connections compete for the same output port is investigated. Then, we explored the impact of these behaviors on TCP protocol in long and fast networks (LFNs). Several conditions in which scheduling mechanisms introduce heavy unfair bandwidth sharing and loss burst which impact TCP performance are shown. Packet scheduling algorithms for Ethernet equipments have been designed for heterogeneous traffics and highly multiplexed environments. Nowadays Ethernet switches are also used in situations where these assumptions can be incorrect such as grid environments. We plan to pursue this investigation of layer two - layer four interaction and explore how to model it and better adapt control algorithms to fit the new applications requirements. We also plan to do the same precise measurements with flow control (802.3x) and sender-based software pacing enabled which both tend to avoid queue overflows.
    Results: This work shows several conditions in which these scheduling mechanisms introduce heavy unfairness (or starvation) on large intervals (300 ms) and loss burst which impact TCP performance. These conditions correspond to situations where huge data movements occur simultaneously. It also shows that behaviors are different from switch to switch and not easily predictable. These observations offer some tracks to better understand layer interactions. They may explain some congestion collapse situations and why and how parallel transfers mixing packets of different connections take advantages over single stream transfers.

  • Grid Network sharing: Rate limitation API design and performance evaluation. (Networking) [achieved]
    Description: The goal of this project is to design and evaluate a grid service to share the network between different kind of flows, different users and different applications. This part of the project focuses on rate limitation mechanisms as a basic block for more complex network service.
    Results: We were able to show that TCP combined with pacing mechanisms offer a good predictability of transfer tasks completion time. More details are availables here: http://www.ens-lyon.fr/LIP/RESO/Results/floc.html

  • Metrology on Grid5000 (Networking) [in progress]
    Description: We want to analyse network traffic on the grid in terms of statistical properties like Long Range Dependance, self-similarity, etc. We especially want to understand the impact of statistic characteristics of the traffic on the QoS. The experiments consist in creating traffic with some imposed characteristics (flow size distribution, etc.) and looking at the resulting arrival and bandwidth processes and the QoS.

  • Congestion Collapse in Grid'5000 (Networking) [achieved]
    Description: Call for Demos: Congestion control train-wreck workshop at Stanford: Call for Demos We would like to invite you to a two-day congestion control workshop, titled "Train-wrecks and congestion control: What happens if we do nothing?", which we are hosting at Stanford on 31 March - 1 April, 2008. Spurred on by a widespread belief that TCP is showing its age and needs replacing - and a deeper understanding of the dynamics of congestion control - the research community has brought forward many new congestion control algorithms. There has been lots of debate about the relative merits and demerits of the new schemes; and a standardization effort is under way in the IETF. But before the next congestion control mechanism is deployed, it will need to be deployed widely in operating systems and - in some cases - in switches and routers too. This will be a long road, requiring the buy-in of many people: Researchers, product developers and business leaders too. Our own experience of proposing new congestion control algorithms has been met with the challenge: "Show me the compelling need for a new congestion control mechanisms?", and "What will really happen to the Internet (and my business) if we keep TCP just the way it is?" As a community, we need examples that are simple to understand, and demonstrate a compelling need for change. We call them the "Train wreck scenarios". Examples might show that distribution of video over wireless in the home will come to a halt without new algorithms. Or that P2P traffic will bring the whole network crashing down. Or that huge, high-performance data-centers need new algorithms. Whatever your favorite example, we believe that if we are collectively armed with a handful of mutually agreed examples, it will be much easier to make a business case for change. Or put another way, if we can't articulate compelling examples to industry leaders, then is the cost and risk of change worth it? The goal of the workshop is to identify a handful of really compelling demonstrations of the impending train-wreck. The outcome will be a set of canonical examples that we will use to persuade industry of the need for change. We are deliberately inviting you many months ahead of time - to give you time to create your compelling train-wreck demonstration. You can choose the way you present your demonstration: You could bring equipment and show a live-demo; you could show simulations or animations; or you could produce a video showing a real or synthetic demo. Whatever method you choose, the goal is to create a case that will persuade a mildly-technical but influential business leader of the need for change. We will invite a panel of judges to give prizes for the most compelling examples in two categories: (1) The Overall Most Compelling Example, which will be judged on a combination of the technical merits and the presentation of the scenario, and (2) The Most Technically Compelling Example, which will be judged on its technical merit alone, without consideration of the way it is presented. The whole purpose of the workshop it to focus on the {\em problem}, not the solutions. We are most definitely {\em not} interested in your favorite scheme, or ours. So we need some ground-rules. \begin{center} {\em No-one is allowed to mention a specific mechanism, algorithm or proposal at any time during the workshop: Not in their talk, not in a panel, and not in questions to the speakers. The only mechanisms that will be allowed mention are: TCP (in its standard and deployed flavors), and idealized alternatives for purposes of demonstration. For example, comparing TCP with an oracle that provides instantaneous optimal rates to each flow.} \end{center} Attendance to the workshop will be by invitation only - to keep the discussion focused and lively. We will video the entire workshop and all the demonstrations, and make it publicly available on the Internet. We will make any proceedings and talks available too. The goal is to open up the demonstrations for public scrutiny and feedback after the event. The event is hosted by the Stanford Clean Slate Program - http://cleanslate.stanford.edu - and local arrangements will be made by Nick McKeown and Nandita Dukkipati. The workshop has received offers of support and funding from Cisco Systems and Microsoft. We hope to make a limited number of travel grants available. We have a small Program Committee (listed below) to select the final demonstrations. We are soliciting a 1-page description of your demo. Please note the following dates.

Nandita Dukkipati, Stanford/Cisco/Princeton --------------------------------------------------------------------------------------------- * Context and objectives Today, the capacity and the usage of the Internet is funda- mentally changing. In the forthcoming year, millions homes will have access to the Internet with fibber lines. Network companies will offer speeds on fibber of up to 1 Gbps. Con- sequently ultra-high-speed applications will be enabled for low-cost, such as high-definition teleconferencing, telemedicine and advanced telecommuting for people working from home. We then propose a demonstration which aims at showing that the traditional congestion control approach may present a strong barrier to the large scale deployment of these excit- ing and very useful envisioned applications exploiting of the emerging huge access capacities. * Scenario description Within this scenario, we plan to show that without any special mechanisms to script the organisation of these trans- fers, the low aggregation level that could be found in this kind of networks quickly lead to a huge congestion level, disrupting the bulk data transfers and deeply impacting all interactive traffic. We will use a hierarchical dumbbell, with 10 Gbps bottle- necks as seen in Figure 1. 100 independent sources in a real testbed will generate bulk data transfers. Other sources will create interactive sessions in both directions. All sources will be using 1 Gbps Ethernet network cards, which means that the aggregation level will be 10 for the local level and 1 for the Internet level. As an addition, we plan to use an hardware latency emulator to simulate long distance links. Two kinds of workloads will be injected: · Long running heavy flows, simulating input data needed from distributed computing, whose sizes are following a distribution law with a heavy tail and a minimum size of 5 Gb · Interactive flows, simulating web traffic or remote com- mands through SSH The reference heavy flow source will be performing bulk data transfers on a regular basis to highlight the impact of the current congestion level on the transfer. The reference interactive flow source will also be used to monitor and show the impact of the congestion level on interactive work. The metric that will be considered here is the transfer completion time, as it is relevant to what the user want: receiving its file in a reasonable time. Three measurements will be performed. The first one cor- responds to the case where our special heavy flow is alone in the system, the second one is the case where the heavy flows are supposed to used an oracle that allow to perform a fair sharing of the bandwidth (each heavy flow strictly get 1/100 th of the bandwidth). Finally, in the third experiment, standard TCP will be used to handle the congestion.

  • Networking performance evaluation of a Xen-based virtual router for HIPerNET (Networking) [achieved]
    Description: This experiment was performed in the context of the ANR HIPCAL project. In this experience, the network performance in terms of throughput, latency and the associated CPU overhead on Xen 3.1 virtual machines have been evaluated in different situations in order to analyse the performance of a virtual router. The different test scenarios have been packet sending, receiving and forwarding on a set of concurrent virtual machines (from 1 to 8 virtual machines running in the same physical machine). The tests have been performed in the Xen default configuration and with different configurations of the Xen Credit-CPU-scheduler. The experience involved from 1 to 17 physical nodes.
    Results: Network performance improved significantly from Xen 3.1 version to Xen 3.2 version. In 3.1 the bandwidth and CPU sharing was unfair between concurrent virtual machines receiving TCP flows. In Xen 3.2, this problem does not persist. The overall throughput improved for sending and receiving, reaching classical linux performance. Forwarding on virtual routers gives slightly lower performance. TCP forwarding on virtual machines gives only about 80% of the throughput on classical linux with Xen 3.2. Major overheads are a very huge CPU cost in dom0 during network communications and additional packet copy due to virtualization.

  • Virtual Network Control (Networking) [in progress]
    Description: This experiment was performed in the context of the ANR HIPCAL project. Its goal is to evaluate rate control mechanisms on virtual links to provide strong isolation between virtual networks, especially in HIPerNET. Traffic is limited on virtual end-hosts and directed over virtual routers which perform rate control.
    Results: The results show that this model allows to give users minimum bandwidth guarantees and provides performance isolation in terms of networking.
  • Investigating self-similarity and heavy tailed distributions on a large scale experimental facility (Networking) [achieved]
    Description: After seminal work by Taqqu et al. relating self-similarity to heavy tail distributions, a number of research articles verified that aggregated Internet traffic time series show self-similarity and that Internet attributes, like WEB file sizes and flow lengths, were heavy tailed. However, the validation of the theoretical prediction relating self-similarity and heavy tails remains unsatisfactorily addressed, being investigated either using numerical or network simulations, or from uncontrolled web traffic data. Notably, this prediction has never been conclusively verified on real networks using controlled and stationary scenarii, prescribing specific heavy-tail distributions, and estimating confidence intervals. In the present work, we use the potential and facilities offered by the large-scale, deeply reconfigurable and fully controllable experimental Grid5000 instrument, to investigate the prediction observability on real networks. To this end we organize a large number of controlled traffic circulation sessions on a nation-wide real network involving two hundred independent hosts. We use a FPGA-based measurement system, to collect the corresponding traffic at packet level. We then estimate both the self-similarity exponent of the aggregated time series and the heavy-tail index of flow size distributions, independently. Comparison of these two estimated parameters, enables us to discuss the practical applicability conditions of the theoretical prediction.

  • TCP traffic self-similarity under loss (Networking) [in progress]
    Description: Over the last decade, many research efforts have been devoted to the study of aggregated traffic time series collected at the core of networks. The pioneering works by Paxson and Leland showed that the Poisson hypothesis, which is relevantly used in phone networks, was not suitable to describe computer networks. Instead, self-similarity was proved a much more appropriate paradigm. Then, the theoretical work from Taqqu and collaborators identified the heavy-tailed nature of the file size distribution as a possible origin for the observed self-similarity. In addition, it gave the exact relation between the self-similarity index and the tail index that should be observed when the sources behavior is modeled with the ON/OFF model. Despite a controversial debate on the question, it has then been more recently stated that the TCP congestion control mechanism cannot be responsible for the self-similarity observed in the large time scales. On the opposite side, we show in this work that when the file size is heavy-tailed, the TCP congestion control mechanism under sufficiently high loss can annihilate the self-similarity that would be observed without any loss. For this work, we use large scale controled experiments performed on Grid5000. Independant TCP sources send files in an ON/OFF scenario with a heavy-tailed ON periods; and a constant loss rate is created via UDP cross traffic.

    Abstract: In the context of network traffic analysis, we address the problem of estimating the tail index of flow (or more generally of any group) size distribution from the observation of a sampled population of packets (individuals). We give an exhaustive bibliography of the existing methods and show the relations between them. The main contribution of this work is then to propose a new method to estimate the tail index from sampled data, based on the resolution of the maximum likelihood problem. To assess the performance of our method, we present a full performance evaluation based on numerical simulations, and also on a real traffic trace corresponding to internet traffic recently acquired.

    Abstract: Researches in network traffic analysis embrace a large diversity of goals and are based on a variety of methodologies and tools. To have a better insight on the real nature and on the evolution of network traffic we argue that fine-grain analysis of real traffic traces have to complement simulations studies as well as coarse grain measurement performed by classical flow measurement systems. In particular, packet level measurements and analysis are needed. However, such methodologies are resource consuming and require very high performance devices to be operational in real high speed networks. In this paper we present the \emph{Metroflux} system which aims at providing researchers and network operators with a very flexible and accurate packet-level traffic analysis toolkit configured for 1~Gbps and 10~Gbps speed links. This system is based on the GtrcNet FPGA-based device technology and on specific statistical analysis tools. We show the potential and the facilities offered by the \emph{Metroflux} system coupled with the \emph{Grid5000} large scale experimental platform and the Network eXperiment Engine (\emph{NXE}) we have developed. We illustrate the application of the \emph{Metroflux} system with the practical validation of the theoretical prediction relating self-similarity and heavy tails given by Taqqu theorem. We also illustrate several usages of this toolset, such as the investigation of conditions under which several traffic theories apply, as well as studies on traffic, protocols and systems interactions.

    Abstract: Modern experimental researches on networks are facing some difficulties due to the emergence of very high speed links (10~Gbps). It raises the challenging issue of monitoring these very high speed links at a fine grain. In this paper, we present MetroFlux: a fully operational metrology platform which enables to capture the traffic at packet level on a very high speed link. This platform is based on GNET10, a FPGA based hardware network emulator. The architecture of this capture device is exposed, and we extend all the offered possibilities. The utilization of MetroFlux is then presented in two situations. Firstly it was used to monitor a core link of a fully controlled experiment grid platform, Grid5000, which enables to choose a lot of parameters (aggregation level, congestion, source flow size distribution, etc.). Secondly, the capture device was used to monitor a production link. In both cases, we give examples of results that can be achived thanks to the use of MetroFlux.

    Abstract: Large scale distributed systems like Grids are difficult to study only from theoretical models and simulators. Most Grids deployed at large scale are production platforms that are inappropriate research tools because of their limited reconfiguration, control and monitoring capabilities. In this paper, we present Grid?5000, a 5000 CPUs nation-wide infrastructure for research in Grid computing. Grid?5000 is designed to provide a scientific tool for computer scientists similar to the large-scale instruments used by physicists, astronomers, and biologists. We describe themotivations, design considerations, architecture, control, and monitoring infrastructure of this experimental platform. We present configuration examples and performance results for the reconfiguration subsystem.
