Abstract
-
This thesis examines the technological requirements and assesses the performance analysis and feasibility for implementing a truly native end-to-end Optical Ethernet infrastructure seamlessly stretching from enterprise LAN to Metro to Global. Specifically, this work proposes and devises both short and long-terms innovative, graceful networking transition scenarios to evolve Ethernet into a next generation networking technology that can truly support carrier-class Ethernet services.;The proposed short-term solution addresses the immediate need for legacy systems to support evolving Ethernet services. It utilizes current Layer 2 technology and expands it into the MAN, WAN and long haul networks over DWDM or MPLS Core infrastructures. It also addresses the current Ethernet shortcomings such as spanning tree protocol and the lack of QoS support required by most applications. Specifically, we introduce a new admission control mechanism that addresses key challenges within an end-to-end service architecture. Hence, we define a novel E-UNI and E-NNI with QoS support. The CoS service performance models proposed by this research is vital for expanding Metro Ethernet into the Core and Long Haul as well as provide the opportunity to standardize Ethernet services (voice, data and video) in the metro, wide, national and global networks.;The proposed long-term solution presents an ambitious vision of how to implement a truly native end-to-end layer-2 MAC frame-based Optical Ethernet infrastructure seamlessly stretching from enterprise LAN to Metro to Global. We show that by combining the simplicity and cost effectiveness of Ethernet technology with the ultimate intelligence of WDM-based optical transport layer, Optical Ethernet (Ethernet-over-WDM) could evolve as a next generation networking paradigm that provides a seamless global transport infrastructure for end-to-end transmission of native Ethernet frames.;The proposed Optical Ethernet networking architecture is a true two-layer model, realizing the significant goal of Ethernet-over-WDM, where native Ethernet frames are mapped directly over WDM. It offers significant advantages over existing Layer-2 and MPLS solutions in that it divorces the Ethernet from legacy transport mechanisms like SONET/SDH and other layer-2 protocols.;The primary rational behind our vision is decreased cost and complexity in the network. This is how Ethernet won the LAN years ago; it was not necessarily the best technology, it was the most cost-effective and easily implemented. Simplifying network design and reducing costs by utilizing Ethernet as an end-to-end LAN/MAN/WAN protocol is the key for Ethernet to win the MAN and WAN.
