“…The control software for ExoGENI was developed and refined in an ongoing collaboration between RENCI and Duke University to create a GENI testbed "island" around the Breakable Experimental Network [1] (BEN), a multi-layer optical testbed built by the State of North Carolina and managed by RENCI. The project grew into a more comprehensive effort to support a federated IaaS system linking BEN and other infrastructure systems under orchestrated control and a common authorization framework.…”

NSF's GENI program seeks to enable experiments that run within virtual network topologies built-toorder from testbed infrastructure offered by multiple providers (domains). GENI is often viewed as a network testbed integration effort, but behind it is an ambitious vision for multi-domain infrastructure-asa-service (IaaS). This paper presents ExoGENI, a new GENI testbed that links GENI to two advances in virtual infrastructure services outside of GENI: open cloud computing (OpenStack) and dynamic circuit fabrics. ExoGENI orchestrates a federation of independent cloud sites and circuit providers through their native IaaS interfaces, and links them to other GENI tools and resources.The ExoGENI deployment consists of cloud site "racks" on host campuses within the US, linked with national research networks and other circuit networks through programmable exchange points. The ExoGENI sites and control software are enabled for software-defined networking using OpenFlow. ExoGENI offers a powerful unified hosting platform for deeply networked, multi-domain, multi-site cloud applications. We intend that ExoGENI will seed a larger, evolving platform linking other third-party cloud sites, transport networks, and other infrastructure services, and that it will enable real-world deployment of innovative distributed services and new visions of a Future Internet.

“…This comprises a potentially essential functionality for high-capacity networks and will enable the monitoring and isolation of physical-layer impairments, in addition to the fast evaluation of the optical quality-of-transmission (QoT) of the transmitted data signals. These metrics can then provide a means of feedback to higher network layers or a control plane to optimize global routing and network performance [3,4]. Several optical parameters can be monitoring, including signal power, wavelength, optical-signal-to-noise ratio (OSNR) [5][6][7], chromatic dispersion (CD) [8], and polarization-mode dispersion (PMD) [9].…”

A cross-layer network platform may enable introspective access to the physical layer, allowing optical performance monitoring measurements to feedback to higher layers for packet rerouting and protection. We experimentally demonstrate quality-of-service-aware packet protection that leverages cross-layer signaling based on the monitoring of packets' optical-signal-to-noise ratio. In order to detect degraded data streams, the monitoring system is based on a delay-line Mach-Zehnder interferometer and a field-programmable gate array. The system is realized in an experimental cross-layer enabled optical packet switched fabric, measuring the optical-signal-to-noise ratio for 10-Gb/s OOK streams. The packet protection scheme uses the dynamic performance measurements to actuate a rerouting of high-quality-of-service packets. 8 × 10-Gb/s wavelength-striped optical messages are rerouted through the fabric error-free (bit-error rates less than 10(-12)).

Abstract-The next-generation Internet may be required to invoke quality-of-service classes directly on the optical layer to optimize global network routing, as well as exploit optical packet switched architectures as a solution to switch high-bandwidth optical messages. In this work, the functionality of optical networks is enhanced to implement different service classes directly on the optical layer. A physical-layer quality-of-service encoding scheme is introduced for an optical switching fabric test-bed that allows for the prioritized transmission of broadband wavelength-striped messages. Contention is resolved by dropping low-priority messages. Packets with 8 10-Gb/s payloads are shown correctly routed error-free, with verified bit-error rates less than 10 12 .A power penalty of 1.2 dB for the three-stage network test-bed is demonstrated.
