This paper presents an efficient multicast routing algorithm called DNMA. According to our simulation results, the proposed algorithm outperforms some existing well-known approaches for solving QoS of multicast routing problem in large scale networks.
We investigate hierarchical label recognition for optical codes encoded in time and spectral domains. A proposed integrated-optic acoustooptic processor can recognize partial labels. The device is useful for layer control of routing.
For ASON/GMPLS multi-domain networks, three routing models, such as per-domain routing, ASON hierarchical routing, and PCE-based routing, have been being standardized. We compare these three routing models in terms of path-computation capabilities, online path-planning capabilities and inter-domain confidentiality.
This paper discusses a novel packet routing network architecture using bufferless routers. Two routing control methods, ldquoan extended routing table methodrdquo and ldquoa coordinate routing methodrdquo, are proposed and evaluated for their feasibility for next generation high-throughput optical networks.
We propose a routing strategy for all optical packet network. This algorithm is based on the decomposition of the topology onto two cycles. This strategy provides a bound on the End to End delay.
This paper compares two GMPLS schemes for bidirectional lightpath provisioning. The novel scheme based on the label set, where both directions are set up with a backward reservation, is assessed against the standard scheme based on the upstream label, where the reverse path is established with a forward reservation unaware of wavelength availability. Results show that the label set scheme significantly...
Ultra-fast self-routing of DPSK signals is demonstrated using a single processor for multiple spectral codes based on four-wave-mixing and selective filtering. A family of 10 codes with maximum bin separation for 10 and 20 Gb/s rates is demonstrated.
In OPS networks, the contention resolution is one of the main problems. To reduce these contention events, we aim the effective use of wavelength resources with a routing and wavelength assignment method. In addition to this, the collision avoidance devices, such as wavelength converters, can improve the network performance more flexibly. The proposed method focuses on not only how to assign route...
