Enhanced Parallel Iterative Schedulers for IBWR Optical Packet Switches
In this paper we propose an enhanced parallel iterative scheduler for IBWR synchronous slotted OPS switches in SCWP mode. It obtains a maximal matching of packet demands without resource conflicts. The analytical and numerical results are highly competitive regarding previous work.
متن کاملMaking Parallel Packet Switches Practical
A parallel packet switch (PPS) is a switch in which the memories run slower than the line rate. Arriving packets are spread (or load-balanced) packet-by-packet over multiple slower-speed packet switches. It is already known that with a speedup of , a PPS can theoretically mimic a FCFS output-queued (OQ) switch. However, the theory relies on a centralized packet scheduling algorithm that is esse...
متن کاملDimensioning of Optical Codes in OCDM/WDM Optical Packet Switches
In this paper we investigate the performance of an Optical Code Division Multiplexing/Wavelength Division Multiplexing (WDM/OCDM) Optical Packet Switch when impairment due to both Multiple Access Interference and Beat noise are taken into account. Analytical models are introduced to dimension the switch resources, in particular the number of optical codes carried on each wavelength. The Packet ...
متن کاملIntegrated photonic switches for nanosecond packet-switched optical wavelength conversion.
We present a multifunctional photonic switch that monolithically integrates an InGaAsP/InP quantum well electroabsorption modulator and an InGaAs photodiode as a part of an on-chip, InP optoelectronic circuit. The optical multifunctionality of the switch offers many configurations to allow for different optical network functions on a single chip. Here we experimentally demonstrate GHz-range opt...
متن کاملPerformance Analysis of WDM Optical Packet Switches with . . .
For lack of optical random access memory, optical fiber delay line (FDL) is currently the only technology to implement optical buffering. Feed-forward and feedback are two types of FDL structures in optical buffering, both have advantages and disadvantages. In this paper, we present a novel architecture for WDM optical packet switches with an effective hybrid FDL buffering that combines the mer...
