We propose a dynamic routing and frequency slot assignment algorithm for SLICE networks that employ distance adaptive modulation. We verify that the spectrum utilization penalty that stems from non-un...
Wavelength-selective spatial routing is proposed for photonic networks and demonstrated on an electro-optic microring switch. This technique yields greater path diversity in photonic networks, enablin...
We propose an immediate re-routing (IRR) extension to RSVP-TE signaling and implement it on our IDBR test-bed. By allowing wavelength conversion during the re-routing process, the proposed scheme can ...
We consider, for the first time, the problem of flexible/open wavelength assignment and propose an optimal as well as heuristic solution. Simulation results validate our solution to within 15% of the ...
We propose and demonstrate, for the first time, service multicasting by all-opticalrouting of 1 Gb/s IR-UWB using XGM of SOA. This technique has potential applications for integrating IR-UWB with WDM ...
A multi-layer grooming and routing method, which considers the optical layer constraints, is proposed. This method, based on a new modeling, allows significant resource saving with respect to a layer ...
We propose a novel outer-ROADM-ring (ORR) based multi-domain routing scheme in optical WDM networks. Results show that this scheme has both high scalability and low blocking probability, while preserv...
A heuristic optimization framework is proposed for routing virtually-concatenated 100Gb/s Ethernet over optical transport networks with distributed differential delay compensation.Under short computin...
We propose a novel information-diffusion-based routing (IDBR) scheme in wavelength routed WDM mesh networks. The IDBR scheme has the fast convergence and the low bandwidth consumption of OSPF-TE while...
An abstraction scheme for delay-based metric advertisement of virtual intra-domain links is proposed for multi-domain traffic engineering. The scheme guarantees an effective combination of blocking pr...
We design a cost efficient routing algorithm and prototype a network planning tool to cost-effectively provision high-speed connections over a large carrier’s heterogeneous core DWDM network with mult...
In large-scale hybrid wireless-optical broadband access networks, the availability of wireless links and optical links varies considerably. Availability-aware routing can significantly improve availab...
Three operational routing algorithms for hierarchical Automatically Switched Optical Networks (ASON) are proposed. Their effectiveness is demonstrated in terms of blocking probability and time perform...
ln all optical routing the main question is the permissible distance. Signal power is a key resource. The most common idea of resource balancing is Traffic Engineering. We will show with examples and ...
We investigate static and dynamic routing approaches in overlay IP/GMPLS over optical networks.Dynamic operation for full-wavelength services benefits from physical-layer impairment aware routing wher...
