TCPivo is implemented on commodity hardware using widely available open-source software and can be used as a cost-effective means for evaluating the performance of networking devices. To achieve high throughput and accuracy, TCPivo employs novel mechanisms for managing trace files and accurate lowoverhead timers. In addition, through the use of low-latency kernel patches and priority scheduling, TCPivo can be made highly resilient to background system load. Using these mechanisms, the tool is able to support packet replay at rates well above OC-3 on an x86-based server.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123275754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The functionality of routers is steadily increasing and complex processing of packet payloads is being implemented (deep packet classification, encryption, content transcoding). We show two examples where processing cost can contribute to a significant portion of the overall packet delay. To enable a more precise consideration of processing delay, we present a tool called NPEST (Network Processing Estimator). NPEST is a framework on top of which packet processing functionality can be implemented and simulated using an actual processor simulator. NPEST can be programmed in C and greatly simplifies the implementation and simulation process as compared to using network processor simulators. The results derived from NPEST can either be used directly or be aggregated to processing statistics for network simulations. We present such results for two prototype applications: IP forwarding and IP security. We also show a comparison between the results obtained from NPEST and an Intel IXP1200 network processor.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124066234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper is motivated by the fact that a large number of published papers in empirical networking analysis follow a generic framework that might be formalized and generalized to a large class of problem. The objective of this paper is to present an interpretation framework and to illustrate it by examples coming from the networking literature. The aim of the paper is rather to give to the researcher who is confronted to measurements coming from a network some guidelines on how to formalize the way to address interpretation of observations.The paper is based on the remark that interpretation is essentially a matter of relating observed effects to hidden causes. This problem might be formalized in its most general setting as an inverse statistical inference problem. The paper illustrates this inverse statistical problem in the context of two well-referred problems: interpretation of active measurement and network tomography. It shows that even if at first glance these two problems are different, the solution framework is the same. We will also give description about how to solve that inverse statistical inference problem by the EM method or the Bayesian framework.The framework provided in this paper is a powerful solution to address the complex problem of interpreting measurement over Internet and network modelling.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121253405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We then define several similarity metrics to compare artificially generated topologies with real world topologies.

A number of recently proposed emulation testbeds have clearly demonstrated the advantage and promise of this approach. Meanwhile, more efforts are necessary to achieve higher degree of flexibility and customizability, especially for the creation of arbitrary network topology and for the customization of network-level entities.In this paper, we present vBET, an efficient and flexible emulation testbed using the virtual machine technology. Based on Linux, vBET can be installed in a high-end desktop or a commodity server and is therefore easily deployable in a research lab. vBET creates a virtual distributed environment with both network infrastructure and end systems. Each entity, such as a router, switch, firewall, or application-level proxy, is emulated by a virtual machine running unmodified system or application software. The entities emulated by vBET are user-configurable. Furthermore, the same (physical) vBET server can be easily setup as testbed for different experiments, such as Internet routing, distributed firewalls, and peer-to-peer networks.We describe the design, implementation, and application of vBET. For the design and implementation, we present key enabling techniques including virtual OS, virtual networking, and small-footprint file system. For the application of vBET, we demonstrate the creation of different experimental environments using vBET, including OSPF routing, distributed firewall, and Chord peer-to-peer network. These experiments reflect the versatility, customizability, and efficiency of vBET.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132124669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is difficult to model and simulate the Internet traffic because of the network's great heterogeneity and rapid change. The statistical properties of Internet traffic not only constantly change over time but also vary in other dimensions such as locations and directions. Previously we have developed a tool RAMP that supports rapid parameterization of traffic models from live network measurements. In this paper, we first extend RAMP to support near-real-time trace-driven simulation. Next, we demonstrate the applications of RAMP via three case studies: generation of realistic traffic model for simulation, generation of high bandwidth synthetic network traces, and analysis and modeling of malicious traffic. Finally, we discuss some lessons we learned from using RAMP for traffic modeling.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127288842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a seminal paper, Philips et al. introduce an algorithm for generating member groups with different degrees of affinity (clusteredness) and show that affinity can have a significant effect on multicast efficiency. Subsequent studies applying this algorithm have all used the algorithm's input parameter as a method for classifying and comparing affinity groups. In this paper, we propose several distance- and expansion-based analysis metrics and find them to be better measurements of the true affinity of member groups. In three separate case studies (multicast, replica placement, and sensor networks), we demonstrate the benefit of classifying member groups by their true affinity in order to predict network performance variation. By systematizing techniques for measuring affinity, we open the door for more realistic and reproducible research in studies employing affinity-based member selection techniques.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129512964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, anyone with a good understanding of networking in general can easily understand how the simulations are constructed. Further, our simulator is implemented completely in object-oriented C++, which leads to easy extension by users to experiment with new or modified behavior of existing simulation models. Our tool is designed from the beginning with scalability in mind, including the support for distributed simulations on a network of workstations as part of the basic design.We give an overview of the features of GTNetS, and present some preliminary scalability results we have obtained by running GTNetS on a computing cluster at the Pittsburgh Supercomputer Center.","PeriodicalId":293967,"journal":{"name":"Workshop on Models, Methods and Tools for Reproducible Network Research","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125027654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
