There is an emerging wide interest to transition from legacy WAN transport technologies to Ethernet-based technology. The current round of carrier Ethernet standards will successfully equip service providers (SPs) with the required tools to provide carrier-grade scalability and to provision and engineer connection-oriented point-to-point (P2P) packet trunks across a native Ethernet infrastructure. Building on these standards, this paper demonstrates how to support and implement full traffic engineering in a global-scale, two-tiered native Ethernet-over-WDM optical networking architecture. To achieve these objectives, several networking innovations are presented and developed including: 1) a GMPLS-based unified control plane that offers a tighter integration between layer-1 (optical transport layer) and layer-2 (Ethernet layer), 2) a fully distributed integrated routing and signaling framework for dynamically provisioning Ethernet switched paths (ESPs) at any bandwidth granularity including both full wavelength and finer granularity (sub-lambda) ESPs in an integrated Ethernet-optical networking environment, and 3) a novel notion of an integrated link-state advertisements strategy that is consistent with a fully integrated routing and signaling protocol

This paper devises and examines via computer simulation an innovative fully distributed global information- based integrated signaling framework for dynamically provisioning EVCs at any bandwidth granularity including both full wavelength and finer granularity (sub-lambda) EVCs at the optical layer.

This paper presents a signaling framework for supporting and implementing traffic engineering in an all Ethernet global multi-service infrastructure.

An optical multihop network architecture that uses wavelength-based cell-switching and that consists of optically separated passive star couplers interconnected by 2*2 electronic asynchronous transfer mode (ATM) switches (network interface units) is presented. A fixed assignment TDMA-WDMA scheme provides a means for sharing the passive star couplers' bandwidth without cell collisions. Adaptive shortest path cell routing exploits the multiplicity of paths in the multihop environment to reduce queuing delay and provide load balancing across all WDMA channels. Analytic models of general network performance are developed and verified by means of computer simulation. The network performance for ShuffleNet configurations is quantitatively studied. The proposed architecture provides for unlimited scalability, both geographically and in the number of users, and is less costly and complex to implement than conventional multihop approaches.>
