Cross-Layer Communication With an Optical Packet Switched Network via a Message Injection Control Interface

Abstract

Abstract-Message injection control and queue management for an optical packet switched network is demonstrated via interoperation of a network with an optical interface buffer. In a time-slotted manner, cross-layer signaling is employed between the input buffer and network to dynamically reroute dropped payload packets with multiple wavelength-striped 10-Gb/s channels. At the output of the network, error-free transmission with bit-error-rates less than 10 012 were confirmed, with an introduced power penalty of 3.5 dB.

Demonstration of Programmable Broadband Packet Multicasting in an Optical Switching Fabric Test-bed

“…The switching fabric is based on an earlier demonstrated OPS network test-bed [3]. We have previously shown the flexibility of the architecture by implementing cross-layer information exchange between the OPS network and an interface buffer, thus mitigating unsuccessful transmission and packet loss through the network [4]. The distributed nature of the fabric's control routing logic yields a high level of reprogrammability and reconfigurability, which is further leveraged in this work to demonstrate a straightforward enhancement to support the multicast operation.…”
