| Summary: | Large Networks inherently have multi-level structure where service networks such as the Internet and the telephone networks offered at the upper level are over transmission networks such as Synchronous Optical Networks (SONET), Wave-Division Multiplexing (WDM) networks which are at lower level. In this thesis, we consider the issue of understanding the interaction between two layers; in particular, when a packet-switched network is at the upper level and the physical transmission network is at the lower level. Toward this end, we have developed a mapping model, MaNIp, to map demand from upper level to lower level network that addresses network optimization, especially to consider a link failure. Further, this mapping tool is then aligned with the packet-based simulator, MoMaRS, in order to be able to do analysis for multi-layer effect. We have conducted a sampling of performance studies to show how this environment allows a user to study multi-layer effect, especially in case of a physical layer failure with staggered and simultaneous recovery. |
