Optical networks and the related technologies, network management software and services
have undergone remarkable developments, and such networks are now the ultra-high …

Multicasting is inevitable in the advent of the age of online video streaming. Light trail, the
unidirectional optical bus, enhances multicasting by facilitating sub wavelength granularity …

In this paper we address the problem of constrained optimization (ILP formulation) and
propose a set of heuristic algorithms for assigning light-trails to WDM ring networks to …

Light-trail is an efficient and feasible technology for IP transport over all-optical networks.
The proposition of light-trails for all-optical networks has demonstrated a number of …

Light-trail has emerged as a promising candidate for enabling IP over WDM networks. The
problem of static light-trail assignment is to find a set of light-trails to cover the given traffic …

Backbone networks are migrating to IP over WDM architectures. In such multi-layer network
configurations, it is necessary to combine efficiently the resources of both layers in order to …

A light trail is a unidirectional bus from a convener node to an end node, whose
communication channel can be accessed at any intermediate node resulting in higher …

Light trail is a unidirectional optical bus between the source and the destination node of a
WDM network. In this paper, a novel algorithm is proposed for dynamic light trail assignment …

Traffic grooming continues to be a rich area of research in the context of WDM optical
networks. We provide an overview of the optical and electronic grooming techniques …

Traffic grooming is a technique that integrates multiple low-rate traffic into a single
communication channel to improve bandwidth usage efficiency. Light trail is a technology …
