Flow level performance analysis of a multi-service system supporting elastic and adaptive services

Performance Analysis of the Uplink of a CDMA Cell Supporting Elastic Services

“…Unfortunately our setting destroys the product form solution but leads to a quasi birth-death structure that still allows for efficient solution of the system, at least when the number of service classes is low. It has been observed by several papers that for elastic services not only the first, but also the second moment of the actual holding time has an impact on the user perceived QoS [5], [6]. Therefore, we also develop a modified Markov model that allows us to arrive at numerical results for the second moment of the elastic class holding time.…”

Effectiveness analysis of resource usage of multiservice information and telecommunication network

“…Дальнейшее развитие методов построения ИТС тре-бует разработки и внедрения методов адаптивного управ-ления, обеспечивающих высокую эффективность ис-пользования ресурсов сети путем учета характеристик ISSN 2226-3780 реального потока данных [6]. В связи с этим, одной из актуальных задач является исследование и мате-матическое моделирование факторов, определяющих эффективность ИТС.…”

Throughputs in processor sharing models for integrated stream and elastic traffic

“…In several papers [11,16,17] the timeaverage throughput, defined as the expected throughput the 'server' provides to an elastic call at an arbitrary (non-idle) time instant, is applied to approximate the call-average throughput. Many other papers use the ratio of the expected transfer volume and the expected sojourn time as an approximation [1,2,3,4,9,31]. In this paper we introduce the expected instantaneous throughput, i.e.…”
