Optical network democratization

Abstract: The current Internet infrastructure is not able to support independent evolution and innovation at physical and network layer functionalities, protocols and services, while at same time supporting the increasing bandwidth demands of evolving and heterogeneous applications. This paper addresses this problem by proposing a completely democratized optical network infrastructure. It introduces the novel concepts of the optical white box and bare metal optical switch as key technology enablers for democratizing optical networks. These are programmable optical switches whose hardware is loosely connected internally and is completely separated from their control software. To alleviate their complexity, a multi-dimensional abstraction mechanism using software-defined network technology is proposed. It creates a universal model of the proposed switches without exposing their technological details. It also enables a conventional network programmer to develop network applications for control of the optical network without specific technical knowledge of the physical layer. Furthermore, a novel optical network virtualization mechanism is proposed, enabling the composition and operation of multiple coexisting and application-specific virtual optical networks sharing the same physical infrastructure. Finally, the optical white box and the abstraction mechanism are experimentally evaluated, while the virtualization mechanism is evaluated with simulation.

Approaches to multiple service delivery over passive optical networks

Abstract: Summary form only given. From the earliest descriptions of passive optical networks (PONs), the idea of using the tremendous bandwidth of optical fiber to provide diverse services has been advocated, and using wavelength-division multiplexing (WDM) was suggested early and more formally proposed a few years ago. In such a system, passive power splitters are used to convey multiplexed information between the headend or Central Office (CO) and the subscribers. Early subscribers, and those declining more advanced services, operate in one region of the optical spectrum, while other regions of the optical spectrum are reserved for more advanced services in the future. We propose a modest generalization of this view by identifying the different services as being provided by different providers. That is, different service providers use different regions of the optical spectrum, sharing the same physical network but operating with distinct services and even distinct terminal equipment.

All the animals in the zoo: the expanding menagerie of optical components

Abstract: Diverging optical network requirements are driving innovations in optical components in multiple directions. The telecommunications network core needs new components to increase capacity while reducing cost: optics that enable faster line rates, more wavelengths per fiber, and longer spacing between repeaters. Metro networks need components to handle complex traffic patterns. A desire for network reconfigurability in both long-haul and metro segments drives demand for switches, but also for other associated components to condition signals after switching. The next generation of optical transport equipment will rely on new types of optical components to perform functions that do not yet exist in the network.
