The recent online news recommendation systems such as Google News and Yahoo! News produce real-time decisions for ranking and displaying highlighted stories from massive news and users access per day. The more relevant highlighted items are suggested to users, the more interesting and better feedback from users achieve. Therefore, the distributed online learning can be a promising approach that provides learning ability for recommender agents based on side information under dynamic environment in large scale scenarios. In this work, we propose a distributed algorithm that is integrated online K-Means user contexts clustering with online learning mechanisms for selecting a highlighted news. Our proposed algorithm for online clustering with lower bound confident clustering approximates closer to offline K-Means clusters than greedy clustering and gives better performance in learning process. The algorithm provides a scalability, cheap storage and computation cost approach for large scale news recommendation systems.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127665190","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 primary reference time clock (PRTC) located in core centers provides reference time and phase synchronization signal traceable to a recognized time standard UTC(*) for other clocks within the telecommunication networks. The performance monitoring to secure stringent time/phase is a key point for providing better Quality-of-Services (QoS) in LTE / LTE-Advanced networks. In this paper, we demonstrate PRTC time/phase accuracy monitoring against UTC(*) with our proposed time comparison system for assuring network performance. Furthermore, the system can also be used to remotely calibrate the PRTC by GPS common-view technique. The performance of GNSS-based PRTC is evaluated with direct measurement mode and the GNSS common-view mode by our proposed system, respectively. The analytical results show that the proposed system offers a worthy performance monitoring and remote calibration schemes for monitoring GNSS-based PRTCs cloud in telecommunication networks.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117262493","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}

It is thus essential to analyze such massive amounts of data reflective of the big data era. Recently, Apache Spark has become popular for analyzing big data, since it can process streaming data and support real-time in-memory computing. Also, it is known to execute applications faster than traditionally used Hadoop. Also cloud technology provides flexible resource utilization environment on-demand. When analyzing big data using Spark in existing environments, it is difficult to provision resources according to the system's changing environment and the influence of other users' executions. Using cloud technology however, it is possible to provision resources more effectively for the execution of jobs through dynamic resource provision methods. In this paper, we propose an auto-scaling framework with corresponding algorithms to manage resources dynamically in virtual environments, in order to meet user-specified SLA (Service Level Agreement) given a set of limited resources. Our experimental results on Spark in OpenStack demonstrate the effectiveness of scaling resources to satisfy user SLAs.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132405446","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}

These proposals have raised a new issue, which is fairness among these modern TCPs. For this issue, several fairness evaluations and some proposals for improving fairness were published. In our past work, we focused on Controlling Queue Delay (CoDel) and proposed a method for improving performance fairness of modern TCPs by modifying CoDel. However, this existing method assumed that the most bandwidth-consuming connection was given for network elements. In this paper, we discuss a method for improving TCP fairness without such an assumption. First, we present fairness evaluation among modern TCPs with and without CoDel, and then demonstrate that fairness among these TCPs is very poor. Second, we propose a method for improving performance fairness. The method monitors network packets and guesses the most bandwidth-consuming connection from the monitored packets. Then, it drops packets in the most bandwidth-consuming connections more aggressively in the network element. Third, we evaluate our proposed method and show that our method can improve performance fairness.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123539607","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}
