Regional Testbed Optical Access Network (Project HELIOS)

摘要

This final technical report presents the results and conclusions from a set of research objectives posed by the Helios project. The objectives included: The study of all-optical LAN architectures and protocols; the establishment of a testbed for the purpose of demonstrating high-bandwidth applications and collecting and analyzing statistical profiles of their traffic; and the study of propagation of analog signals through all-optical networks. The report is structured as follows: Sections 2, 3 and 4 describe MCNC-RDI's work on the HiPeR-1 protocol and scheduler for broadcast WDM LAN architectures. Section 5 describes the application testbed established between MCNC-RDI, NCSU and UNC- CH using NON infrastructure for the purpose of accumulating statistical information about traffic demands of high-bandwidth applications. Section 6 describes the application cluster established within MCNC-RDI in order to test high-bandwidth/high-compute demand applications. Section 7 describes the research performed at Lucent Bell Labs concerned with transporting analog signals over DWDM optical links including physical layer impairments and adaptation layer studies. Section 8 describes the work performed jointly by UNC- CH and the University of Pennsylvania to establish a multimedia network testbed for telepresence applications. The Appendices present some of the technical details related to the HiPeR-1 scheduling protocol developed and implemented by MCNC-RDI.
