This paper describes an interface between the established configuration tool LCFG, and the experimental configuration tool PoDlM. The combined system is used to generate explicit real-world configurations from high-level, constraint-based specifications. The concept is validated using live data from a large production installation. This demonstrates that a loosely-coupled, multi-layer approach can be used to construct configuration tools which translate high-level requirements into deployable production configurations.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115267459","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}

In this paper, we propose an information retrieval model for use in large dynamic networks such as the Internet. Firstly, we divide the network into a number of groups. An exceptional handling mechanism is adopted, i.e., a controlled flooding algorithm for intre-group information updating and random walk algorithm for inter-group information retrieval. We also propose an equal representative mechanism to enhance the fault-tolerant ability of the system. Extensive experiments are conducted to evaluate the performance and rationality of our model. The experimental results show that our model outperforms the existing approaches on the retrieval efficiency and the fault-tolerant ability.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127137758","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}

On this algorithm the calculating routing table divides into two parts, inner routing table between Forwarding Elements and outer routing table between routers. Then according to both routing tables the Control Element calculates the final routing table of each Forwarding Element. An independent routing server is used for the routing process, which decreases the amount of development work. This algorithm satisfies the distributed characteristic of ForCES router and reduces the amount of computation of Forwarding Element obviously. The algorithm has been applied at a prototype of ForCES router with satisfactory result.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126720431","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}

Currently DiffServ-based MPLS networks are able to the development of efficient methods for QoS provisioning. This article analysis, through computer simulation, the performance of WFQ schedulers in a DiffServ node loaded by long range dependence (LRD) traffic. The adopted process for the traffic generation consists in the aggregation of the traffic produced by several TCP connections transmitting files with a size that is modeled by heavy tail distribution. This distribution was obtained, from the Internet, by one-week long measurements. The objective is to observe the bandwidth distribution obtained with the WFQ scheduler, as well as the latency, i.e., the file transfer average delay, in an environment with different priorities. Simulations were carried out with the network simulator NS-2, and several simulation results are presented and analyzed.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126974658","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}

There has been an increased targeting of Windows end-users and servers. The attackers and intruders are leveraging easily identifiable network blocks to target and exploit Windows end-user servers and computer systems. In order to provide some level of security and protection against security attacks, the Microsoft's Windows XP operating systems were designed with an additional level of security. The initial Microsoft's windows XP without service pack2 (SP2) provided windows firewall with some security features. The later version of Microsoft's windows XP with SP2 intends to provide enhanced security features to prevent and mitigate the adverse effect of security attacks on the host computer systems. In this experimental paper, we set out to conduct real TCP-SYN attacks on computer systems in a controlled lab environment and measure the effectiveness of Microsoft's windows XP without SP2, and with SP2 in preventing TCP-SYN attacks. The Windows firewall (without SP2) was found to be not effective against the TCP-SYN attacks. However, the later version of Microsoft's Windows XP with SP2 was found to significantly help mitigate the adverse effect of the TCP SYN attacks on Windows based computer systems.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116050531","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 main research challenges are identifying and refining realistic requirements for a MANET routing protocol and designing such protocol. In this paper we report on the field experiments we performed in order to address this. Our approach builds on energy efficient MANETs to provide continuous monitoring of multidimensional parameters of animal mobility including temporal and spatial walking intensity and feed intake in order to detect oestrus, pregnancy, animal diseases and reduced efficiency of pastures. We support remote and in-situ, specific and range queries and notifications about newly detected events. Our extensive set of emulations show that we achieve lower and more balanced energy consumption while preserving the delays for increasing number of nodes within the user expected boundaries.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129676744","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 macro model resembles a conventional wired network, and allows us to apply extant research on flow control directly to ad hoc networks. In this paper, we further justify the feasibility of applying our macro model of ad hoc networks to access control and the validity of only controlling the flows across bottlenecks. We describe a simple rule that partitions the network into super-nodes. We then introduce a probabilistic geographic routing protocol that routes packets between bottlenecks to avoid congestion within super-nodes. Simulation results show that not only is the average flow in non- bottlenecked areas less than the average flow across bottlenecks, but the flows in each of the transmission areas that is not in a bottleneck are less than the flows in the transmission areas within the bottleneck.","PeriodicalId":250085,"journal":{"name":"Seventh International Conference on Networking (icn 2008)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124011107","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}
