-This paper describes the Gigabit Satellite Network (GSN) being developed under joint sponsorship of NASA and ARPA. The system will use the wide-band Satellite Switched Time Division Multiple Access (SS-TDMA) capability and hopping beam antennas of NASA's Advanced Communications Technology Satellite (ACTS). The GSN network will provide full-duplex SONET services over satellite at OC-3 (155.54 M...

This paper presents the electromagnetic (EM) 3-D modeling, hardware measurement, and optimization of hybrid packaged electro-optical transmitters. The initial application is targeted for 10 Gb/s Ethernet and SONET fiber optic communication links. The hybrid package includes a micromachined silicon optical bench, a InP laser and monitor photodiode, a hermetically-sealed lid, integrated impedance...

Optical networks appear to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. One of the key issues that needs to be addressed is how optical networks can be used to carry IP traffic. In this paper, we survey some of the techniques that have been proposed in the literature for transporting IP traffic over an optical net...

This article discusses various issues around the Transmission Convergence (TC) sublayer in the physical layer of ATM. A brief introduction is given to the layered approach and functionality of the ATM physical layer. This is followed by an introduction to the two main TC sublayer implementations for ATM at high line rates, namely the SONET or SDH option and the CellBased option. These options a...

In this paper the Reactive Local Search (RLS) heuristic is proposed for the problem of minimizing the number of expensive Add-Drop multiplexers in a SONET or SDH optical network ring, while respecting the constraints given by the overall number of fibers and the number of wavelengths that can carry separate information on a fiber. RLS complements local search with a history-sensitive feedback l...

Carrying IP traffic over connection-oriented networks requires the use of bandwidth allocation schemes at gateways or network interfaces. A new virtual queue occupancy, which is more accurate than the classical queue status parameter, is being proposed for periodic bandwidth allocation. Based on this virtual queue occupancy, an enhanced approach for lossless services, referred to as LAVQ, is si...

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) circuits over a Packet Switch Network (PSN). Information about the current status of this document, any errata, and how to provide f...
