CISE Postdoctoral Associates in Experimental Computer Science: On Demand Wavelength Routing In Support Of Flexible And High Speed Internet

99-01579 Chlamtac，ImrichFumagalli，Andrea德克萨斯大学实验计算机科学博士后助理：关于支持灵活和高速互联网的按需波长路由本研究的目的是提供一种创新的解决方案，用于高速接入和骨干网络，以支持直接通过波分复用(WDM)的IP数据传输，从而避免中间协议层，如ATM和SONET。建议的解决方案使用一种允许按需建立光路--所谓的光路或波长路径--的新型控制技术，实现单个IP分组和包括多个IP分组的大量业务的光学传输。博士后研究助理正在接受专门的培训，以开发对当前网络基础设施的全面知识，并确定阻碍实现能够向用户提供按需带宽的灵活电信网络的当前缺陷和瓶颈。研究计划包括对建议的解决方案对当前网络的影响进行评估，具体说明如何规避现有网络的缺陷和瓶颈。为了使提议的解决方案与终端用户的设备兼容并对终端用户的设备透明，我们投入了相当大的努力来研究可能的方法。

99-01579Chlamtac, ImrichFumagalli, AndreaUniversity of Texas at DallasCISE Postdoctoral Associates in Experimental Computer Science: On DemandWavelength Routing in Support of Flexible and High Speed InternetThe aim of this research is to provide an experimental study of an innovative solution for high speed access and backbone networks in support of IP data transmission directly over Wavelength Division Multiplexing (WDM), thus avoiding intermediate protocol layers, such as ATM and SONET. The proposed solution enables optical transmission of both individual IP packets and large quantities of traffic comprising multiple IP packets using a novel control technique that allows on-demand establishment of optical circuits -- the so-called lightpaths or wavelength routes.The postdoctoral research associate is being specifically trained to develop comprehensive knowledge of the current network infrastructure and identify the current drawbacks and bottlenecks that prevent the realization of a flexible telecommunications network capable of providing on-demand bandwidth to the user. The research plan includes an evaluation of the impacts of the proposed solution on the current network, specifically addressing how the drawbacks and bottlenecks of the extant network are circumvented. A considerable effort is devoted to investigate potential ways to make the proposed solution compatible with and transparent to the end user's equipment.
