The rapid advances in dense wavelength-division multiplexing (DWDM)
technology have enabled the provisioning of hundreds of wavelengths on a single
fiber, which has brought about a large increase in the size of optical
cross-connects (OXCs) as well as in the cost and control complexity of such
OXCs. Waveband switching (WBS) is a concept recently introduced to reduce the
cost and control complexity of OXCs. The basic idea of WBS is to group a set of
wavelengths together into a waveband and transmit and switch the waveband
optically using a single port. In a WBS network, a waveband is transmitted and
switched as a single entity whenever possible and is demultiplexed into
individual wavelengths only if necessary. A multigranular OXC (MG-OXC) is
employed not only to switch traffic at multiple levels or granularities such as
fiber, waveband, and wavelength, but also to add and drop traffic at multiple
granularities. Traffic can also be transported from one level to another via
multiplexers within the MG-OXC. By using WBS, the number of ports of an OXC can
be significantly reduced, leading to reduced size, cost, and control complexity
of the OXC. Because of its practical importance, WBS has attracted much
attention from both industry and academia in recent years. To realize the vision
of a WBS network, it is critical to solve various related problems, such as
switch architecture and algorithm design. Owing to the differences in network
design objectives, however, traditional techniques developed for
wavelength-routed networks (WRNs) cannot be directly applied to WBS networks.
This has motivated a large amount of research activities in recent years that
seeks effective solutions to WBS related problems. The aim of this feature issue
is to present a collection of high-quality research papers that reflect the
state-of-the-art research progresses and results in this focus area.
