“…In 2010, GRIPhoN (globally reconfigurable intelligent photonic network) was proposed as an advanced ROADM architecture able to improve the performance and operational flexibility of optical transport networks [16], and was then extensively studied to provide bandwidth on demand for inter-DC connectivity through backbone optical networks [17]. Moreover, optical circuit switching has been proposed to combine both inter-and intra-DC connectivity for long-lived flows [18].…”

-Elastic optical networking (EON) is a viable solution to meet future dynamic capacity requirements of Internet Service Provider (ISP) and inter-datacenter networks. At the core of EON, Wavelength Selective Switches (WSSs) are applied to individually route optical circuits, while assigning an arbitrary bandwidth to each circuit. Critically, the WSS control scheme and configuration time may delay the creation time of each circuit in the network. In this paper, we first detail the WSS-based optical data-plane implementation of a metropolitan network test-bed. Then, we review an SDN application, designed to enable dynamic and fast circuit setup. Subsequently, we introduce a WSS logical model that captures the WSS time-sequence and is used to estimate the circuit setup response time. Then, we present two batch service policies that aim to reduce the circuit-setup response time by bundling multiple WSS reconfiguration steps into a single SDN command. Resulting performance gains are estimated through simulation.

“…Though not as fast as 1+1 protection, this would also be far less expensive. Finally, by using automated bridgeand-roll [34] of private line connections, GRIPhoN minimizes the impact during planned maintenance. Comparison to prior work on dynamic optical networks.…”

“…The controller is responsible for keeping track of the available network resources in its database, communication with the network elements (FXC controllers, OTN switch EMS, ROADM EMS and NTE controllers) in order to create or tear down the connections ordered by the CSPs, capacity and resource management, inventory database management, failure detection, localization and automated restorations. To minimize service interruption during network reconfigurations due to restoration, the GRIPhoN controller executes a bridge-and-roll operation [7,34] that first creates a full new wavelength path (the "bridge") while the original connection is still in use and then quickly "rolls" the traffic onto the new path when ready. The bridge-and-roll results in an almost hitless movement of traffic prior to scheduled maintenance or reversion following a failure restoration (moving traffic from backup paths to repaired primary).…”

Cloud service providers use replication across geographically distributed data centers to improve end-to-end performance as well as to offer high reliability under failures. Content replication often involves the transfer of huge data sets over the wide area network and demands high backbone transport capacity. In this paper, we discuss how a Globally Reconfigurable Intelligent Photonic Network (GRIPhoN) between data centers could improve operational flexibility for cloud service providers. The proposed GRIPhoN architecture is an extension of earlier work [34] and can provide a bandwidth-on-demand service ranging from low data rates (e.g., 1 Gbps) to high data rates (e.g., 10-40 Gbps). The inter-data center communication network which is currently statically provisioned could be dynamically configured based on demand. Today's backbone optical networks can take several weeks to provision a customer's private line connection. GRIPhoN would enable cloud operators to dynamically set up and tear down their connections (sub-wavelength or wavelength rates) within a few minutes. GRIPhoN also offers cost-effective restoration capabilities at wavelength rates and automated bridge-and-roll of private line connections to minimize the impact of planned maintenance activities.
