Data-centric networking using multiwavelength headers/labels in packet-over-wdm networks: a comparative study

Abstract

A multiband diamond-shaped Sierpinski gasket monopole antenna is described. The radiation pattern of wideband monopole antennas like the circular-disk and diamond monopole antennas degrades as frequency increases. In this paper, several cutouts based on the Sierpinski gasket geometry are made in the diamond monopole antenna in order to improve the radiation pattern of the antenna. It is experimentally shown that a multiband diamond-shaped Sierpinski gasket mono-pole antenna with a significant improved radiation pattern can be achieved by making cutouts in the diamond monopole antenna.

Experimental Demonstration of a Dynamic 10 G bit/s WDM Header/Label Recognition Structure

“…Headers and payloads can be transmitted on the same wavelength [5], [6], or on different wavelengths [5], [7]. Also, the payload can be delivered at a designated wavelength while the header is transmitted on multiple wavelengths [8]- [15]. An asynchronous optical packet switched network based on combining wavelength and time for header generation has been reported [15], [16], where payloads is carried on a wavelength while the header is coded on multiwavelength carrier.…”

Employing multiwavelength header patterns enables the node to quickly and efficiently process the header, and easily differentiate it from the payload and extract it from the packet.…”

Multiwavelength correlator for optical header recognition based on arrays of fibre Bragg gratings

“…Recently, the use of multiwavelength headers has been proposed for optical packet switched networks [2,3], where the payload is delivered at a designated wavelength and the header is constructed by a appropriately driving a tunable laser to generate a pattern of optical pulses at different wavelengths. However, this technique requires a fast tunable laser and accurate synchronization in order to modulate optical carriers of different wavelengths by sequentially generated header bits.…”
