Firewall policy is designed under the instruction of security policy. A network security policy is a generic document that outlines the needs for computer network access permissions. And it determines how firewall filters are designed. If inconsistencies, such as redundant filters, insufficient filters or contradict filters, exist between security policy and firewall policy, firewall policy could not filter packets exactly, and the network protected by the firewall will be affected. To resolve this problem, we propose an inconsistency detection system to detect the inconsistencies between the security policy and firewall policy. When the administrator could not get host IP addresses, port number and other specific values, according to the network configurations, our proposed system could transform the network security policy and firewall policy to the same range value, represent and analyze their spatial relationships to detect their inconsistencies. The proposed system has been successfully implemented in a prototype system. We have been confirmed the effectiveness of the proposed system.","PeriodicalId":375145,"journal":{"name":"2010 First International Conference on Networking and Computing","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123965026","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 static network performance of the MH3DT has already been studied and has been shown to be good. Dynamic communication performance has been evaluated using dimension-order routing and 2 virtual channels under uniform traffic patterns but not under non-uniform traffic patterns. In this paper, we evaluate the dynamic communication performance of MH3DT under five non-uniform traffic patterns, and compare it with other networks. We found that under non-uniform traffic patterns, the MH3DT yields high throughput and low latency, providing better dynamic communication performance compared to H3DT, TESH, mesh, and torus networks. Also, we found that non-uniform traffic patterns have higher throughput than uniform traffic patterns in the MH3DT network.","PeriodicalId":375145,"journal":{"name":"2010 First International Conference on Networking and Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129379911","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}

To protect such contents from being distributed to unauthorized peers, Lou and Hwang proposed a proactive content poisoning scheme to restrain an illegal download conducted by unauthorized peers, and a scheme to identify colluders who illegally leak the contents to such unauthorized peers. In this paper, we propose three schemes which extend the Lou and Hwang's colluder detection scheme in two directions. The first idea is to introduce an intensive probing to the check of suspected peers, and the second idea is to adopt a reputation system to select reliable (non-colluder) peers as a decoy. The performance of the resulting scheme is evaluated by simulation. The result of simulations indicates that the proposed schemes detect colluders 30% earlier in average than the original scheme while keeping the accuracy of the colluder detection at medium collusion rate.","PeriodicalId":375145,"journal":{"name":"2010 First International Conference on Networking and Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130123564","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}

Since the rarest first policy adopted in the Bit Torrent protocol could not collect all pieces corresponding to a video file by their playback time, we need to develop a new piece selection rule particularly designed for P2P VoDs. In the proposed scheme, we assume the existence of a media server which can upload any piece upon request, and try to bound the load of such media server by carefully discriminating pieces to be requested, by taking into account the rareness of the pieces held by its nearby peers, estimated size of the overlay network, and the file size to be downloaded.
