Domain requirements are core domain asset in software product line engineering, and requirement analysis for domain products or solutions based on domain requirements is a key step. Previous domain requirement models are suitable to model tens of variabilities in a domain which contains only a limited number of products. But in a solution domain such as SDP (service delivery platform) domain of telecom, there are thousands of variabilities among the solutions. In this paper, a new domain requirement model for solution domains is proposed. In this model, domain requirements are organized with three kinds of aggregation relationships and three kinds of generalization relationships. Based on these relationships, a configuration model is proposed to analyze the commonalities and variabilities among domain solutions. A solution requirement analysis method is also described based on the new domain requirement model. A case study is conducted on SDP domain which demonstrates how the proposed domain requirement model and solution requirement analysis method is used.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132635966","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 realtime multimedia service provisioning in WLAN-based on home/office intranet, however, it is essential to have an efficient QoS-guaranteed session management scheme between QAP and STAs. In this paper, we propose an efficient home/office intranet resource management scheme using Q-SIP/SDP for realtime stream service provisioning on IEEE 802.11e-based WLAN. For the QoS-guaranteed session allocation for realtime stream services (i.e., IPTV and VoIP), the proposed intranet resource management system exchanges control messages with Q-SIP(QoS Session Initiation Protocol) proxy server that communicates with QSTAs (QoS Stations), and controls the QAP (QoS access point) of IEEE 802.11e WLAN. The proposed Q-SIP/SDP session management scheme is also considered for DLS (Direct-Link Setup) for making QoS-guaranteed session between STAs located in same BSS (basic service set). The intranet management system is implemented using WBEM architecture, and provides resource discovery, WLAN channel allocation with CAC, and performance monitoring of each QBSS (QoS basic service set).","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241380","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 work we describe first a method for monitoring and modeling of performance degradation in SOA applications, particularly application servers. This method works for a large class of the aging processes caused by resource depletion (e.g. memory leaks). It can be deployed non-intrusively in a production environment, under arbitrary service request distributions. Based on this schema we investigate in the second part of the paper how machine learning (classification) algorithms can be used for proactive detection of performance degradation or sudden drops caused by aging. We leverage the predictive power of these algorithms with several techniques to make the measurement-based aging models more adaptive and more robust against transient failures. We evaluate several state-of-the-art classification methods for their accuracy and computational efficiency in this scenario. The studies are performed on a data set generated by a TPC-W benchmark instrumented with a memory leak injector. The results show that the probing method yields accurate aging models with low overhead and the machine learning approach gives statistically significant short-term predictions of degrading application performance. Both approaches can be used directly to fight aging via adaptive software rejuvenation (restart of the application), for operator alerting, or for short-term capacity planning.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115609393","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}

Models and simulations appear as major tools aiming at better understanding the expenditures and to allow a more realistic network planning. However, their focus was, in the past, mostly limited to infrastructure investments. Because emerging services pose special requirements towards the networks, operators have not only to extend the capacity of their transport networks, but also need to optimize the architecture for differentiated services with advanced packet switching technologies, referred to as Next Generation Networks (NGN). During network evolution with disruptive technology changes, a general problem faced by network operators is the service migration of active services from an existing platform into a newly setup platform. This work investigates strategies for service migration at minimized overall operational costs. A novel service migration cost model based on queueing theory and hill climbing optimization is provided in order to tackle the employee allocation optimization problem. Based on this framework, a thorough techno-economic analysis of costs and benefits is presented.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116947615","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}
