Currently many streaming videos are delivered in one way, in spite of the bi-directional network connection. To have more interactivity in use of them, we have implemented a system for viewers to control the original unedited video sources with active viewing interfaces. The system allows video source owners to share video sources without editing, and viewers to reorganize them while receiving from the streaming server. With the implemented system, viewers can utilize the video sources in more effective way for educational purposes","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125420196","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}

First, we show that network anomalies generating a huge number of small flows, such as network scans or SYN flooding, become difficult to detect when we execute packet sampling. This is because such flows are more unlikely to be sampled than normal flows. As a solution to this problem, we then show that spatially partitioning the monitored traffic into groups and analyzing the traffic of individual groups can increase the detectability of such anomalies. We also show the effectiveness of the partitioning method using network measurement data","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115527327","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}
