End-to-end performance of an optical transparent packet network

This papers investigate the overall traffic performance of a transparent Optical Network, suitable for high bit rate interconnection, The motivation of the introduction of such a transport network: are discussed and network; architecture is presented. Performance are investigated in an end-to-end perspective. On one side Me traffic resulting at the output of the interface with other networks, such as ATM for instance, is studied showing an interesting traffic shaping effect. Than this traffic is taken as input to optical switches showing that the target performance in terms of packet loss can be reached with present technology both in the access as well in the core part of the network. An approximate evaluation of the end-to-end delay experienced by data crossing the Optical Network in a typical operating environment is given showing the effectiveness of the approach presented.
