Abstract
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 throughput, robustness,
and security. For optical networks, the potential for using
network coding to provide survivability is especially noteworthy
as it may be possible to allow for the ultra-fast recovery time
of dedicated protection schemes with the bandwidth efficiency
of shared protection schemes. However, the need to perform
computations at intermediate nodes along the optical route leads
to the undesirable necessity of either electronically buffering and
processing the data at intermediate nodes or outfitting the network
with complex photonic circuits capable of performing the
computations entirely within the optical domain. In this paper,
we take the latter approach but attempt to mitigate the impact of
the device complexity by proposing a low-complexity, all-optical
network coder architecture. Our design provides easily scalable,
powerful digital network coding capabilities at the optical layer,
and we show that existing network coding algorithms can be
adjusted to accommodate it.
