In this paper, we report on the dynamic services provisioned optical transport (DynaSPOT) test-bed—a next-generation metro ring architecture that facilitates provisioning of emerging services such as Triple Play, Video-on-Demand (VoD), pseudowire edge-to-edge emulation (PWE3), IPTV, and Data Center Storage traffic. The test-bed is based on the recently proposed strongly connected light-trail (SLiT) technology that enables the triple features of dynamic provisioning, spatial subwavelength grooming and optical multicasting—that are quintessential for provisioning of the aforementioned emerging services. SLiT technology entails the use of a bidirectional optical wavelength bus that is time-shared by nodes through an out-of-band control channel. To do so, the nodes in a SLiT exhibit architectural properties that facilitate bus function. These properties at the network side include ability to support the dual signal …
