Network coding, a networking paradigm in which different pieces of data are coded together at various points along a transmission, has been proposed for providing a number of benefits to networks including increased ...

In this paper, we investigate the application of network coding to all-optical networks from both the algorithmic and infrastructural perspectives. We study the effectiveness of using network coding for optical-layer ...

In this paper, we consider the problem of topology design for both unprotected and one-link protected all-optical networks. We investigate the problem of selecting switching sites to minimize total cost of the network. The ...

A design of a nonblocking, all-optical lightpath concentrator using wavelength exchanging optical crossbars and WDM crossbar switches is presented. The proposed concentrator is highly scalable, cost-efficient, and can ...
