The solution conforms to the packet conservation principle and uses a hybrid loss and delay based congestion control algorithm. The framework is evaluated over both simulated bottleneck scenarios as well as in a LTE system simulator and is shown to achieve both low latency and high video throughput in these scenarios, something that improves the end user experience.","PeriodicalId":106412,"journal":{"name":"Proceedings of the 2014 ACM SIGCOMM workshop on Capacity sharing workshop","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127816942","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}

This is particularly important in mobile environments where varying channel conditions, user mobility, and interference lead to a variation of the available network resources which ultimately affects application quality. A flexible selection of one or more access technologies, however, allows to overcome resource limitations of one specific access technology. An over-the-top (OTT) virtual access network (VAN) approach allows the aggregation of multiple wireless networks into a single IP pipe to provide users more bandwidth. To minimize energy consumption and radio resource utilization, an application-tailored usage of the access technologies as well as appropriate resource scheduling mechanisms in case of concurrent usage are required. In this paper, we perform a scenario-based investigation of the performance of an OTT VAN architecture. As scenario we choose a user watching a YouTube video clip, while a Wi-Fi and a cellular network are available. We evaluate the user perceived quality, cellular usage, and device power consumption based on testbed measurements.","PeriodicalId":106412,"journal":{"name":"Proceedings of the 2014 ACM SIGCOMM workshop on Capacity sharing workshop","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127957431","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}

Over buffering or 'bufferbloat' may produce unacceptable end-to-end delays, while static small buffers may limit the performance gains that can be achieved with various 802.11n enhancements, such as frame aggregation. We propose WQM, a queue management scheme customized for wireless networks. WQM adapts the buffer size based on measured link characteristics and network load. Furthermore, it accounts for aggregate length when deciding about the optimal buffer size. We implement WQM on Linux and evaluate it on a wireless testbed. WQM reduces the end-to-end delay by up to 8x compared to Linux default buffer size, and 2x compared to CoDel, the state-of-the-art bufferbloat solution, while achieving comparable network goodput. Further, WQM improves fairness as it limits the ability of a single flow to saturate the buffer.","PeriodicalId":106412,"journal":{"name":"Proceedings of the 2014 ACM SIGCOMM workshop on Capacity sharing workshop","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129818302","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}
