The load-balanced switch architecture is a promising way to scale router capacity. It requires no centralized scheduler, requires no memory operating faster than the line-rate, and can be built using a fixed, optical mesh. In a recent paper we explained how to prevent packet mis-sequencing and provide 100% throughput for all traffic patterns, and described the design of a 100Tb/s router using t...
Introduction The optical-label switching (OLS) technology supports transparent all-optical routing and sophisticated network functions by processing the short label in the electronic domain while leaving the data payload in the all-optical domain [1]. In this way, the routing is independent of the payload data format and bit rate. Moreover, with the help of electronic circuit, the router can su...
This paper presents a novel scheme for scheduling packet traac on a wavelength-division-multiplexed (WDM) local optical network which employs a wavelength router. An N physical wavelengths. We propose TDM schedules for interconnecting MN nodes with a wavelength router. We show that for non-zero transceiver tuning time, throughput on the order of N can be achieved.
The IST-LASAGNE project aims at designing and implementing the first, modular, scalable and truly alloptical photonic router capable of operating at 40 Gb/s. The main results achieved in the project are presented in this paper, with emphasis on the implementation of network node functionalities employing optical logic gates and optical flip-flops, as well as an economical study on the proposed ...
Recent advances in generalized multiprotocol label switching (GMPLS) [1,12] and the extensive study and understanding of packet-over-optical network architecture, has made it possible for a single integrated control plane to manage the resources of the packet network and underlying optical transport network in an unified manner. This opens up the possibility for coordinated actions across the t...
A detailed analytical traffic model for all-optical wavelength division multiplexing (WDM) photonic packet-switched networks is presented and the requirements for buffer size and link dimensions are analyzed. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different destinations through preferr...
