0115779 SohrabyDescription: This project supports collaborative research by Dr. Khosrow Sohraby, Professor of Computer Science and Telecommunications (CST), University of Missouri-Kansas City (UMKC), and Dr. Nail Akar, Department of Electrical and Electronics Engineering, Bilkent University, Ankara, Turkey. The investigators will study traffic modeling and analysis and traffic engineering as applied to telecommunication networks. Queuing systems are the fundamental systems in telecommunication networks, of which traffic is the major constituent. Solution of queuing systems in most cases reduce to the solution of a certain set of structured Markov chains if the traffic and server process are modeled as Markovian processes. The two scientists have introduced a new paradigm "Generalized Invariant Subspace Approach," which was used to numerically solve a set of structured Markov chains, the so-called M/G/1-type Markov chains. They plan to extend the applicability of the approach to a wider set of Markov chains, used in numerical solution of queues ranging from fluid queues to random servers, and from finite capacity queues to continuous-time queues. They also plan to introduce an interdisciplinary technique using "optimal control" to set the foundation for a theory to synthesize path-splitting mechanisms that are used in engineering of current Internet infrastructures.Scope: This project enables two qualified scientists with complementary expertise to address a problem that is important in the management of Internet and wireless data transmission. The two scientists collaborated in the 1994-1996 period and produced significant results. This project will allow them to combine expertise in this multidisciplinary research field to produce a very generic engine that solves most Markovian systems that arise in the field of performance evaluation of communication networks. One or more graduate students from Bilkent University are expected to join the research at UMKC.

0115779 Sohraby描述：该项目支持密苏里大学堪萨斯城分校（UMKC）计算机科学与电信（CST）教授Khosrow Sohraby博士和土耳其安卡拉Bilkent大学电气与电子工程系Nail Akar博士的合作研究。 研究人员将研究通信建模和分析以及应用于电信网络的通信工程。 业务系统是电信网的基础系统，业务是电信网的主要组成部分。 在大多数情况下，排队系统的解决方案减少到一定的一组结构化马尔可夫链的解决方案，如果业务和服务器过程建模为马尔可夫过程。 这两位科学家介绍了一种新的范式“广义不变子空间方法”，用于数值求解一组结构化马尔可夫链，即所谓的M/G/1型马尔可夫链。 他们计划将该方法的适用性扩展到更广泛的马尔可夫链，用于从流体队列到随机服务器以及从有限容量队列到连续时间队列的队列的数值解。 他们还计划引入一个跨学科的技术，使用“最优控制”，为理论的基础，以综合路径分裂机制，用于工程目前的互联网infrastructures.Scope：该项目使两个合格的科学家与互补的专业知识，以解决一个问题，这是重要的互联网和无线数据传输的管理。 两位科学家在1994年至1996年期间进行了合作并取得了重大成果。 该项目将使他们能够联合收割机在这个多学科研究领域的专业知识，以产生一个非常通用的引擎，解决大多数马尔可夫系统出现在通信网络的性能评估领域。 一名或多名来自Bilkent大学的研究生有望加入UMKC的研究。
