However, rapid and complex technology migration, regulatory requirements, and increasing capital expenditures on one side and competitive environments, saturated markets, and pressure on margins on the other side advocate a new paradigm: the focus on ldquocritical success factorsrdquo and ldquokey assetsrdquo. Simultaneously, telecommunications equipment is commoditized. These trends are paving the way for the sharing of network infrastructure in the core and radio access networks among multiple operators. Challenges arise with regard to technical solutions to enable such business models in a multi-vendor landscape, but also in the context of the principal-agent-problem accompanying the re-allocation of assets and operational duties. This paper investigates the current technological, regulatory, and business landscape from the perspective of sharing network resources, and proposes several different approaches and technical solutions for network sharing. We introduce a model for estimating savings on capital and operating expenses, and present the results of our simulations for the various scenarios. Finally, we assess the benefits of ldquoManaged Servicesrdquo for the shared network case, a potentially highly attractive model to overcome some of the challenges posed by infrastructure sharing.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134150394","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}

This assumption, however, is not realistic in actual IT systems because failures during the execution of changes do happen and cannot be ignored. In order to address this issue, we propose a solution where tightly-related change activities are grouped together forming atomic groups of activities. These groups are atomic in the sense that if one activity fails, all other already executed activities of the same group must rollback to move the system backwards to the previous state. The automation of change rollback is especially convenient because it relieves the IT human operator of manually undoing the activities of a change group that has failed. To prove concept and technical feasibility, we have materialized our solution in a prototype system that, using elements of the business process execution language (BPEL), is able to control how atomic groups of activities must be handled in IT change management systems.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"43 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":"126053071","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}

First of all, we present an algorithm for pointwise Holder exponents estimation based on the decay trends of wavelet coefficients in time windows. The Holder exponents which measure the degree of local irregularities of the traffic processes are intended to provide performance improvement over existing data flow scheduling strategies. For this end, based on this traffic irregularity indicator, we develop a new scheduling scheme for Internet data streams under the GPS (generalized processor sharing) protocol environment. The novelty of this scheduling discipline consists of using the pointwise Holder exponents to determine the link capacity allocation priority for the involved data streams. More precisely, the main goal is to achieve a good sharing of the total link transmission rate by data streams, achieving lower data loss. The proposed data flow scheduling algorithm is extensively evaluated through simulations. The simulation results show that the proposed scheduling scheme provides lower data loss rate as well as higher link utilization than the conventional GPS scheme which is widely employed in many active communication networks.","PeriodicalId":368139,"journal":{"name":"NOMS 2008 - 2008 IEEE Network Operations and Management Symposium","volume":"47 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":"117020030","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}
