A flow routing for optical networking play a vital roles in maintaining packet sequence. In this paper, an analytical method is proposed in order to show the effectiveness in increasing the goodput of the router especially during the congestion period. Discarding technique has been proposed in order to measure the goodput. There are three cases that have been investigated in this research such as...
In overlay IP over WDM networks, there are only limited information exchanges between the two layers through the user network interface (UNI) [1] for service requests and responses. To enhance the overlay network performance while maintaining its simplicity, we propose for the first time to learn from the historical data of lightpath setting up costs maintained by the logical layer network operator(s),...
Lightpath reconfiguration performance has been evaluated experimentally for regional IP-over-WDM network applications, making the network scalable and stable when traffic changes occur. The reconfiguration performance was examined in an experimental network with reconfigurable optical add/drop multiplexers (R-OADMs) to connect 4 nodes with bi-directional dual-fibers. The experiment was conducted by...
This paper studies the problem of IP traffic grooming in optical wavelength division multiplexed (WDM) mesh networks. Two different grooming architectures are considered: (i) IP/MPLS grooming, and (ii) SONET grooming. The IP/MPLS grooming approach provides a fine level of grooming granularity realized via software based implementations, but has router processing related bottlenecks. The SONET grooming...
