Sun Workstations as Cypress Implets

This paper reports on an experiment in which a Sun 3/50 workstation was used as a packet switch in a leased line based network. We conclude that the Sun is both capable and cost effective. • This work was supported in part by gnmts Iran the National &::iCJlee Foundation's Office. of Advanced Sc:iCJltifie Computing (NSF·851·8639), with addilional supportIrom Digital Equipment CoTpOllltion, CSNET...

Design of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

Analysis of a packet switch with memories running slower than the line-rate*

Our work is motivated by the desire to build a very high speed packet-switch with extremely high line-rates. In this paper, we consider building a packet-switch from multiple, lower speed packet-switches operating independently and in parallel. In particular, we consider a (perhaps obvious) parallel packet switch (PPS) architecture in which arriving traffic is demultiplexed over identical, lowe...

A Novel Packet Switch Node Architecture for Contention Resolution in Synchronous Optical Packet Switched Networks

Packet contention is a key issue in optical packet switch (OPS) networks and finds a viable solution by including optical buffering techniques incorporating fiber delay lines (FDLs) in the switch architecture. The present paper proposes a novel switch architecture for packet contention resolution in synchronous OPS network employing the packet circulation in FDLs in a synchronized manner. A mat...
