A light-trail is a generalization of a lightpath such that multiple nodes can take part in communication along the path. Light-trail based networks lead to dynamic provisioning and optical multicasting while deploying a pragmatic low-cost platform. Dynamic connections can be setup and torn down over semi-permanent light-trails facilitating bandwidth-on-demand and optical multicasting. We introduce...
Light-trail as a candidate for dynamic provisioning and sub-wavelength grooming has been investigated before. A light-trail is an example of an intelligent unidirectional wavelength bus. In this article, we extend the conceptual advantages of light-trails to a bidirectional wavelength bus, which we call as SLiT or strongly connected light-trails. We investigate and propose new node architecture for...
In this paper we enhance the concept of a single unidirectional light-trail into a new concept called SLiT or strongly connected light-trails that improves utilization and lowers costs. We showcase architecture, performance and cost benefits
