To maximize user experience, we propose that traffic be prioritized based on the specific activity of the user: the more a user interacts with an application and its associated traffic flows, the higher the priority that the application's traffic should receive. We introduce a client-side application that resides on the user's machine that monitors user activity and interaction with the application. This application sends information to the home router about user activity associated with different traffic flows; the home router then prioritizes traffic for flows that correspond to interactive traffic over those that are not. Finally, we introduce a protocol that allows the router and application to communicate. We show that the collective system improves the user experience for interactive applications by providing better performance for traffic associated with applications that a user is interacting with directly.","PeriodicalId":136618,"journal":{"name":"W-MUST '12","volume":"16 35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122531854","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}

Servetti, Juan Carlos De Martin","doi":"10.1145/2342541.2342545","DOIUrl":"https://doi.org/10.1145/2342541.2342545","url":null,"abstract":"End user monitoring of quality of experience is one of the necessary steps to achieve an effective and winning control over network neutrality. The involvement of the end user, however, requires the development of light and user-friendly tools that can be easily run at the application level with limited effort and network resources usage. In this paper, we propose a simple model to estimate packet loss rate perceived by a connection, by round trip time and TCP goodput samples collected at the application level. The model is derived from the well-known Mathis equation, which predicts the bandwidth of a steady-state TCP connection under random losses and delayed ACKs and it is evaluated in a testbed environment under a wide range of different conditions. Experiments are also run on real access networks. We plan to use the model to analyze the results collected by the \"network neutrality bot\" (Neubot), a research tool that performs application-level network-performance measurements. However, the methodology is easily portable and can be interesting for basically any user application that performs large downloads or uploads and requires to estimate access network quality and its variations.","PeriodicalId":136618,"journal":{"name":"W-MUST '12","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124718335","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}
