Such user-initiated network performance measurements push the ISPs to an ever-high standard, requiring them to know the worst-case performance of its admitted flows, whether and where to accommodate a new flow request, without violating the service agreement level (SLA). Stochastic Network Calculus (SNC) has been developed to derive performance bounds of a network system for many years in the research community. However, it has not been practically adopted by ISPs due to the lack of a tool supporting features such as end-to-end analysis or optimal parameter tuning. In this demo, we extended the DISCO Stochastic Network Calculator. We also compare the analytical results obtained from the tool with the simulation results obtained in NS-3 to validate the tightness of the performance bounds.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128638112","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}

Particularly in instances of smart buildings and hospitals, among others, the flow between indoor locations, and mobility modeling within buildings is of a prime significance. Much of the mobility modeling studies have focused on a user-centric approach for outdoors movement. In this study, we take a location-centric approach for indoor mobility to analyze and characterize region relationships as pertains to user flow. Our study is trace-driven, as we use extensive measurements from wireless LANs, and mine them to quantify metrics for influx and outflux and show their stability for various buildings at university campus involving more than 108K anonymous mobile users and more than 3 million records. The flux degrees are shown to be temporally stable where their coefficient of variations do not exceed 0.42. However, the correlation between the degrees and dynamic spatial density is not always strongly positive and it varies between buildings. Finally, we outline several smart buildings applications of location-centric flow flux.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"65 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129817464","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 propose Stemflow, a new systems framework that provides Inter-Datacenter Overlay as a Service. It is provided as a turn-key solution for applications to conveniently and transparently tap into the available bandwidth resources across datacenters in the cloud, with internal optimizations on the performance of data delivery. Internally, we have implemented Stemflow as a software-defined overlay.

However, it is still a challenging task to guarantee the information security and solve the privacy concerns. We design a new Privacy-preserving Predictive Clinical Decision scheme based on RNN, called PCD, that can predict and alert before diseases occur while preserving the privacy of patients. In PCD, we utilize a homomorphic encryption scheme, so no e-health data will be leaked. PCD could resist various security threats. We design a sequential and an averaged RNN model in real-time systems that is capable to improve prediction accuracy. The experimental results illustrate that our scheme achieves high disease prediction accuracy and time efficiency while protecting privacy of patients.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114421487","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}

An example is the Underwater Acoustic (UWA) channel. Compared to the over-the-air radio frequency (RF) channel, the UWA channel is subject to severe distortions due to Doppler as well as multipath. The challenge of interest is wideband burst communications in such an environment. Thereto the effect of Doppler is modeled as a quadratic time warp. A procedure is developed to estimate the parameters of the time warp based on observed burst signal components, so that subsequently the Doppler time warp can be undone. Two different methods are compared. The first technique uses sinusoids in a pre- and in a post-amble to a communications burst, while the second technique uses out of band (communication signal bandwidth) sinusoids present during the burst. The results, from over-the-air acoustic proxy experiments, show that performance improvements can be realized using the Doppler time warp model and correction process.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124930056","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}

While it is possible to revisit traffic engineering algorithms to explicitly integrate middleboxes, such an approach is not compositional. Existing efforts at compositional SDN application development do not apply since they support application composition after static packet-forwarding policies are generated by application modules. Consequently, routes computed by a traffic engineering module cannot be influenced by the constraints imposed by a module that specifies middlebox traversal requirements. In this paper, we explore an alternate approach where application composition is done prior to the generation of packet-forwarding policies. Each application is written as a logic program, and provides a set of requirements that must be respected by a synthesized solution. A constraint solving engine iterates over these requirements to search the solution space and find a solution respecting all the requirements. We illustrate our approach with a concrete case study, and implement it using the Z3 SMT solver [1]. Our initial results point to the promise of the approach.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123612999","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}
