As a result, the flash crowd appearing in the early stage of a software patch release cannot be handled smoothly with abruptly arriving requests, thus considerable server bandwidth is needed. Unfortunately, it is still unknown how much bandwidth a content provider should provision to handle this case. In this paper, through measurements in one of the largest game patch distribution systems in China, we propose a simple but accurate user demand prediction model, since our finding that a highly predictable pattern of user requests exists in such a system. We further present the design of a pre-fetch based software update system. In this system, users who are idle and capable in hours before the patch release time could fetch the patches in advance and then serve other users requiring the patches. The design of this system mainly includes demand prediction and pre-fetch scale computation. After the deployment of this system, the contribution rate of users increases about 20% in the release day and is more stable than that before. Moreover, the peak of server bandwidth decreases by about 30%, which significantly saves bandwidth cost for providers.</p></div>","PeriodicalId":35359,"journal":{"name":"Journal of China Universities of Posts and Telecommunications","volume":"21 ","pages":"Pages 12-19"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1005-8885(14)60518-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82139604","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}

Although the ACM is valuable, it is not easy to judge the trustworthiness of the reviews and measure the values of the reviews. Based on the online data acquisition technology, we have got the data of 360buy, a domestic large-scale business to customer (B2C) commerce website in China. With application of data-mining and the density clustering algorithm (DBSCAN), we focus on the intervals distribution and the synthetic value of consumer reviews. The distribution of review interval can be depicted by the power-law function which presents a monotonically increasing relationship between the power-exponent and the customers’ concerns with the commodity: the higher the exponent is, the more attention will be drawn. We also find that the value of online reviews can be measured by the expertise value, which is the attraction and the quality of the reviews. Based on the above results, we have constructed the online review-trust model and the synthetic value model. The relationship between the power-exponent and the consumer attention has played a vital role in the consumer attention to online-shopping, and then the synthetic value model will help people find out useful reviews more effectively.</p></div>","PeriodicalId":35359,"journal":{"name":"Journal of China Universities of Posts and Telecommunications","volume":"21 ","pages":"Pages 71-78"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1005-8885(14)60509-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88005965","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}

However, the recommendation systems which using the users' social information have two main problems: the explicit user social connection information is not always available in real-world recommender systems, and the user social connection information is directly used in recommender systems when the user explicit social information is available. But as we know that the user social information is not all based on user interest, so this can introduce noise to the recommender systems. This paper proposes a social recommender system model called interest social recommendation (ISoRec). Based on probability matrix factorization (PMF), the model addresses the problems mentioned above by combining user-item rating matrix, explicit user social connection information and implicit user interest social connection information to make more accurately recommendation. In addition, the computational complexity of our algorithm is linear with respect to the number of observed data sets used in this algorithm, and can scalable to very large datasets.</p></div>","PeriodicalId":35359,"journal":{"name":"Journal of China Universities of Posts and Telecommunications","volume":"21 ","pages":"Pages 26-33"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1005-8885(14)60516-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76192218","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}

Port control protocol (PCP) is one of the important IPv4-in-IPv6 tunnel technologies. Meanwhile, with the increasing demand to communicate or share files between terminal equipment, it is necessary to realize the peer to peer communication to support the transmission of data directly between the terminal equipment without a third-party server. In this paper, the structure of user access network and the deployment of the IPv6 transition technology based on IPv4-in-IPv6 tunnel are analyzed comprehensively, based on which the internet protocol security (IPSec) solution is chosen to protect the security of PCP message and the transport layer security (TLS) solution is chosen to protect the security of the peer-to-peer communications. A system for the authorization and distribution of digital certificates is designed for the TLS solution. Finally, the open source software Openswan is used to implement the IPSec solution, and the open source software OpenSSL is used to implement the TLS solution.</p></div>","PeriodicalId":35359,"journal":{"name":"Journal of China Universities of Posts and Telecommunications","volume":"21 ","pages":"Pages 52-58"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1005-8885(14)60512-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120815135","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}
