We experimentally demonstrate 1-to-9 optical wavelength multicasting, based on dualpump four-wave mixing in highly-nonlinear fiber. A 100-km field trial experiment is also conducted to demonstrate the feasibility of optical wavelength multicasting.
In this paper, we introduce an optical private network service and address its on-demand construction within the network virtualization environment for emerging new type services.
To enable the quick applications and services of new-born innovative optical network service (INS) in large-scale high-end grid computing, we propose an overlay approach to integrate grid and emerging INS resources establishing the value-added optical grid network flexibly cross over multi-domain WSONs. In particular, we introduce an edge-mode approach which flexibly leverages new multi-function wavelength...
In this paper, an all optical wavelength multicasting service in AWG-based WDM PON is introduced, and a novel architecture supporting multiple multicasting groups is proposed. The novel characteristic is that different from the PON systems which broadcast the signals to all the receivers, multicasting signals are only delivered to desired users. This restricted member multicasting brings the trusted...
In this paper we address the optical grid network (OGN) construction issues in a large-scale multi-domain wavelength switched optical network (WSON). Based upon user's needs for high-performance distributed computation, a group of lightpaths are established dynamically among the distributed computer resources forming an on-demand application-oriented communication environment. We propose an optical...

Two novel architectures of remote node supporting all optical wavelength multicasting functionality are proposed.

At a switching node in an optical packet switching (OPS) network, packet contention occurs whenever two or more packets try to reach the same output port of the node at the same wavelength, consequently it degrades network performance. Previous works on optical packet switching flourishingly adopted optical buffering with optical fibre delay line (FDL), wavelength conversion, or deflection routing...
This paper presents an experiment of dynamic optical grid network optimization and provisioning in a wavelength switched optical network test-bed. This paper focuses on control issues encountered in the system implementation.
This paper proposes dynamic host-to-host wavelength path provisioning with distributed host network interface configuration. Path provisioning and host configuration are cooperated to enable automatic distributed communication setup. The implemented system is addressed with experiment result.
This paper presents a direct approach to partitioning for resolving process/processor mapping problems in a heterogeneous grid environment. It employs a scheme of analyzing similarities in graphs to cluster processes and select processors. Based on a phase for pre-analyzing the underlying network topology, it takes the information on the underlying network topology into account to select processors...
We introduce our optical grid infrastructure where end-to-end, bandwidth-guaranteed lightpaths are established simultaneously. This is developed on a lightpath network that employs wavelength-routing. One application may send a request for multiple lightpaths to the network, which establishes the lightpaths one-by-one. Thus, several lightpaths may be rejected due to simultaneous reservation of an...
Given a static traffic condition, the motivation of logical topology design in IP over WDM networks is to optimize the network resource utilization and improve network performance. The objectives of the optimization can be to minimize network congestion or to reduce packet delay in the networks. The logical topology design for IP over WDM networks can be decomposed into several subproblems, some of...
It is predicted that networks in the near future will consist mostly of optical components in order to satisfy growing demands for bandwidth. Although the model of a global all-optical network is not clear in details yet, many researchers are certain that a shift of communication paradigm is to take place. In the world of electric networks, the concept of active measurement is very well established...
