There is a dire need to find new techniques of building in Self-* features in networks for delivering important goals like maintaining uptime and QoS, since system adminstrators are crying for help as complexity of networks and their management systems continues to grow unabatedly and managing them effectively and efficiently turning out to be a veritable nightmare. In this paper we describe how a correlation based parameter-influencer model can be used to build in Self-healing features in a network. We describe various combinations of parameters and influencers which can be used to model features of varying complexity that can be added to networking systems. Statistical techniques like linear regression are used to identify positive and negative correlation amongst parameters and influencers and changes made by the Autonomic Manager(AM) or the network management systems (NMS) to bring the network to a state of stability and thus reduce downtime. Our model is programmed as daemon on the network and two case studies are described where historical data is used to tune the network parameters more accurately. The first demonstrates how uptime can be sustained and the second demonstrates how performance (and in turn QoS) can be maintained.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127471221","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}

One of the main challenges to achieve this goal is the difficulty in providing strict (packet-level) delay guarantees for voice traffic in capacity limited multi-hop wireless networks. In this context, we propose DelayCheck, an online centralized scheduling and call-admission-control (CAC) algorithm which effectively schedules constant-bit-rate voice traffic in TDMA-based mesh networks. DelayCheck solves the joint routing, channel assignment and link scheduling problem while satisfying the constraint. We formulate an offline version of this scheduling problem as an Integer Linear Program (ILP), the LP relaxation of which gives us an optimality upper bound. We compare the output of DelayCheck with the LP-based upper bound as well as with two state-of-the-art prior scheduling algorithms. DelayCheck performs remarkably well, accepting about 93% of voice calls as compared to LP-based upper bound. As compared to state-of-the-art algorithms, DelayCheck improves scheduler efficiency by more than 34% and reduces call rejections by 2 fold. We also demonstrate that DelayCheck efficiently exploits the number of channels available for scheduling. With implementation optimizations, we show that DelayCheck has low memory and CPU requirements, thus making it practical.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128637839","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}

Harrison (2000)), in which there are constraints on which queues can be served simultaneously. Such networks have served as effective models for understanding various types of dynamic resource allocation problems arising in communication networks like the Internet, computer architecture, manufacturing, etc. In such systems, a scheduling policy is required to make resource allocation decisions in terms of which queues to serve at each time subject to constraints. The performance of the system is crucially determined by the scheduling policy. The performance of such scheduling policies, measured with respect to the following three metrics is of utmost importance: (a) capacity, (b) induced queue-sizes or latency, and (c) complexity of the implementation of the policy. Ideally, one is interested in determining the trade-offs achievable between these metrics characterized through the pareto performance boundary. In this note, we shall summarize the state-of-art along with recent progresses towards this somewhat ambitious program.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114687554","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}
