Such systems should meet lots of requirements, such as high availability, low latency, reliability. However, new challenges become more and more important nowadays. One of them is energy efficiency of large scale computing systems. Many service providers prefer to use cheap commodity servers in their distributed infrastructure, what makes the problem of energy efficiency even harder because of hardware inhomogeneity. In this chapter an approach to finding balance between performance and energy efficiency requirements within inhomogeneous distributed computing environment is proposed. The main idea of the proposed approach is to use each node’s individual energy consumption models in order to generate distributed system scaling patterns based on the statistical daily workload, and then adjust these patterns to match the current workload, while using PCPB scheduling strategy to optimize hardware utilization. An approach is tested using Matlab modelling. As a result of applying the proposed approach, large-scale distributed computing systems save energy while maintaining a fairly high level of performance and meeting the requirements of the service level agreement (SLA).","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86378422","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}

However, due to inaccuracies in forecasting the development trends of this type of networks, a situation has arisen whereby 2G and 3G networks will be used to service all voice traffic for a long time. As the research results show, one of the necessary conditions for the normal functioning of networks of mobile operators is the introduction of IP Multimedia Subsystem (IMS) as the main element of the management level. One of the main requirements for the IMS system is the requirement for the reliability of its operation. Since the requirements for reliability are very high, their fulfillment is impossible without the use of reservation methods. Therefore, the paper discusses possible reservation methods for the IMS system. The main elements of the IMS system were determined, models for assessing the reliability of operation with various reservation methods were developed, and a comparative assessment was made.","PeriodicalId":6754,"journal":{"name":"2019 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo)","volume":"21 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91018347","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}
