Two concurrent strategies are commonly used to achieve this operation. On one hand, approaches based on a situated view only gather information in a bounded neighborhood, thus providing a high reactivity to AMs for control operations. On the other hand, approaches based on a global view provide a good accuracy at the cost of a larger convergence time. Being able to choose the best approach in a given context is crucial to ensure the efficiency of an autonomous management system. Thus, in this paper, we perform an exhaustive performance analysis of these approaches by considering typical schemes of both of them, namely a one-hop and two-hops situated view against gossip- and tree-based global aggregation schemes. Metrics we consider are the convergence time, communication and computation cost, scalability and the accuracy of estimated aggregates. Given them, we show under which conditions an approach outperforms the others.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128871543","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 avoid server overload situations, a data center operator needs to decide which VMs should be assigned to a physical server for a given period of time. As assignment decisions are based on historical workload traces, deviations from forecasted demands potentially require the adaptation of VM assignments. However, VM live migrations are inherently overhead afflicted control operations. While it is mandatory to anticipate overload situations in order to trigger VM migrations in a proactive manner, unnecessary VM migrations may have negative impact on the underlying computing infrastructure. Hence, an autonomic controller should accurately predict situations where the aggregated workload of a set of collocated VMs will hit the capacity limit of a server without requiring manual adjustments of control model parameters. In this paper we propose an automated, non-parametric approach for proactive filtering of multivariate workload behavior. We learn an orthonormal projection from historical workload traces and extract a set of key metrics that concisely describe relevant developments in the joint workload behavior of physical servers. A geometric interpretation, in combination with simple short term forecasting techniques allows for reliable decision making. Based on a set of real world workload traces we conduct numerical experiments that validates its superiority and predictive capabilities over simple threshold based approaches.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133445708","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}

IEEE 802.21 MIH in Linux Kernel space for cognitive and smart handovers 用于认知和智能切换的Linux内核空间中的IEEE 802.21 MIH

In the proposed scheme, the surrounding wireless access network information is collected and provided by IEEE 802.21 MIH, and the mobile node (MN) performs time-limited smart scanning with interleaved packet delivery for target access point. For better performance, the MIH functions have been implemented as Linux kernel modules that minimize the overheads in event notification and command processing. During the smart channel scanning,MIH is used to inform the change of MN's operation mode to network (e.g., MAG - mobile access gateway), asking the buffering of downlink packets during the smart scanning. The smart scanning is controlled to limit the service interruption time to be less than 50 ms, in order to guarantee the QoS requirement of realtime multimedia service, especially jitter and packet loss. The overall performances of the MIH operations and QoS provisioning are analyzed in detail. The proposed IEEE 802.21 MIH on Linux kernel can support various horizontal and vertical handovers across heterogeneous wireless access networks for QoS-guaranteed seamless realtime service provisioning1.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133491118","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 an effort to solve this problem, researchers have explored different methods of visualizing network security threats. There is little debate that humans can perceive more information visually than textually. The problem is that the majority of visualization tools in practice or proposed do not take efficient visualization techniques into consideration. As a result, it is difficult to get a high-level view of the network that facilitates rapid isolation of network attacks. We propose the Converged Security Visualization Tool (Cover-VT) to solve the efficient visualization problem. Cover-VT was designed to provide analysts with a high-level view of network threats using geographic information systems. The tool allows for rapid identification of threats by minimizing the cognitive obstacles to efficient threat location. Cover-VT includes the capability to drill-down on a node of interest for additional details and even filter out unwanted data. Cover-VT was designed with usability in mind, making it easy to comprehend while assisting the analyst in rapid threat identification. Many different security tools make up a security analyst's tool kit. Cover-VT was developed as an effective security visualization system that integrates existing security tools and network security systems.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130224404","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}
