Large IP flows at the IP level may be therefore moved to the optical level bypassing the per hop routing decisions of the IP level. Such move could be beneficial since congested IP networks could be offloaded; leaving more resources for other smaller IP flows. At the same time, the flows switched at the optical level would experience better quality of service (QoS) thanks to larger bandwidth and negligible jitter. Moving these large flows to the optical level requires the creation of lightpaths. Current approaches to manage lightpaths rely on decisions of which IP flows will be moved to lightpaths taken by network managers. As a result, only IP flows explicitly selected by such managers will take advantage of being transferred over lightpaths. However, it may be that there are also other large IP flows, not known to the manager, which could potentially profit from being moved to the optical level. The objective of this Ph.D. thesis is to investigate the feasibility of employing self-management capabilities on hybrid optical and packet switching networks in order to autonomically move large IP flows from the IP level to the optical level, as well as, creating and releasing lightpaths to transport such flows at the optical level.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"103 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":"133753250","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}

Current approaches to composite deployments can be categorized as workflow based and model based. In the workflow based approach, deployers create end-to-end workflows to automate application deployment, while in the model based approach architects design detailed “desired state” models and validate they meet all requirements and constraints. Today, there is no formally understood relationship and mapping between “desired state” models and deployment workflows, posing a challenge and limitation on architects and deployers. In this paper we propose a new model based approach to bridge the gap between deployment models and workflows. Our approach supports separation of concerns where basic automation building blocks (such as scripts and workflows) can be developed independently of the resource model and with no knowledge of it. Therefore, the method enables deployers to continue to leverage useful libraries of automation building blocks, while enjoying the benefits of a sound resource model, used for validation and constraint satisfaction. We propose algorithms and implementation to generate end-to-end workflows for input “desired state” resource models, based on given libraries of automation building blocks. Our approach has been incorporated into IBM's leading deployment modeling platform [15] and is in active use by customers in a large range of applications.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"39 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":"131489253","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}

Due to the nature and deployment realities of the protocol (ASCII message representation, most deployments over UDP, limited use of message encryption), it becomes relatively easy to attack the protocol at the message level. To mitigate this, self-learning systems have been proposed to counteract new threats. However the efficacy of existing machine learning algorithms must be studied on varied data sets before they can be successfully used. Existing literature indicates that Euclidean distance based classifiers work well to detect anomalous messages. Our work suggests that such classifiers do not produce adequate results for well-crafted malicious messages that differ very slightly from normal messages. To demonstrate this, we gather SIP traffic and minimally perturb it using 13 generic transforms to create malicious SIP messages. We use the Levenshtein distance, L, as a measure of similarity between normal and malicious SIP messages. We subject our dataset — consisting of malicious and normal SIP messages — to Euclidean distance-based classifiers as well as four standard classifiers. Our results show vast differences for Euclidean distance-based classifiers on our dataset than reported in current literature. We further see that the standard classifiers are better able to classify an anomalous message when L is small.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"80 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":"124006676","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 service providers (PSPs), which are the long term owners of chunks of frequency spectrum, lease portions of their licensed frequency bands to secondary users for short term basis. The PSPs have also their own regular customers who expect to receive a minimum amount of bandwidth and a minimum level of quality of service. The existence of various network elements that want to maximize its own profits makes the problem very complex, with usually conflicting objective functions. The proposed framework in this paper aims at investigating the impact of power emission of secondary users to the pricing process. We have used a model based on game theory for PSPs' pricing problem to provide with a well defined equilibrium. The spectrum demand of secondary users is modeled using the multi-nomial logit (MNL) which is a kind of discrete choice model. We have used the MNL model to estimate the probability that a secondary user chooses a particular PSP as the seller. The application of the framework is shown on a simple demonstrative example. The results show that the proposed framework allows PSPs to make additional profit while preserving the social welfare of the network.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"20 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":"115156798","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 order to reduce the capital expenditure at data centers, virtual server consolidation approaches has been the focus of attention. However, server consolidation inadvertently introduces a new point of failure, which is the physical resource on which the virtual machines are hosted. A common practice is that for a multi-tier application, different tiers of the application are hosted from a single physical machine. Although this is beneficial in maintaining low cost of ownership when the number of hosted applications is low, with increasing number of hosted applications this leads to a skewed distribution of the applications. We propose that spreading the virtual servers of different applications across the available physical resources can lead to a more resilient design for multi-tier application hosting. We formulate the problem of striping the virtual machines across multiple physical machines as an optimization problem. We propose two MIP based techniques, where the first solution is fast but may be infeasible in many cases, while the other one is better in terms of accuracy but takes more time. The solution is tested on data sets representing typical hosting environments.","PeriodicalId":433520,"journal":{"name":"12th IFIP/IEEE International Symposium on Integrated Network Management (IM 2011) and Workshops","volume":"28 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":"125809180","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}
