Abstract:
In the era of information explosions, the size and complexity of data is expanding dramatically. Numerous applications carrying multimedia data translate into significant bandwidth requirements. A network supporting high bandwidth is important since the application performance and overall customer satisfaction may suffer from network traffic congestion caused by insufficient network resources.
This dissertation aims at solving the current limitations on all-optical network from both switching technology and network architecture aspects. From the perspective of switching technologies, the DWDM Multi-Mode router provides an integrated platform to support three different switching technologies simultaneously. The dynamic reconfiguration capability in DWDM Multi-Mode enables the bandwidth sharing among three switching methods which increases the channel utilization. From the perspective of the applications, the Application-Aware (A2) optical network featuring the reverse data path reservation is a good candidate of asymmetric traffic transmission. By creating alternative switching technique towards optical switching network, the A2 optical scheduler eliminates the setup latency problem in traditional optical router. At the same time, the path reservation can be changed in real-time, increasing the probability of packets delivery.
The proposed 3-D switching opens another dimension in optical network to reduce traffic blocking. A dynamical resource allocation scheme is proposed to assign bandwidth for different traffic flows. The hardware experiments show the feasibility of the proposed 3-D switching and it is expected to serve as a building block for future optical networks.
