摘要：

A High Speed Optical Data Transfer Network (HSODTN) experimental research prototype has been constructed for the Naval Sea Systems Command (NAVSEA)1. It was installed at the Naval Research Laboratory (NRL) to explore new high speed fiber optic network concepts and technology applications for broadband communications. The present status and objectives of the HSODTN are outlined. This experimental network utilizes a 1 . 7 Gb/s lightwave transmission system that serves as a fiber optic backbone. It can readily be upgraded to Asynchronous Transfer Mode (ATM)/Synchronous Optical Network (SONET) standards. The basic prototype hardware architecture consists of a network interface (i. e. Media Access Control (MAC) layer) and several independent modular units that interface with various lower bit rate services. At the MAC layer integrated services are supported by giving priority to those traffic types requiring bounded delay. The organization is modular allowing components and services to be added or improved while redesigning the minimum amount of hardware. The software network architecture includes a network controller to configure monitor and administer the network.
