A proof-of-concept, ultra-low latency optical label switching testbed demonstration for next generation Internet networks

Optical label switching testbed has been demonstrated to realize an NGI network with ultra-low latency, simplified protocol stacks, and data transparency. Packet applications have been successfully sent, with less than 1 msec switching node delay, over a label-switched network.

Low latency packet forwarding in IP over WDM networks using optical label switching techniques

We summarise the design and implementation of an ultra-low latency, high throughput Internet protocol (IP) over wavelength division multiplexing (WDM) packet-switched data network for NGI applications, utilizing innovative hardware and software solutions. Optical-label switching (OLS) is the novel method that is used to realize flexible bandwidth-on-demand IP packet transports on a reconfigurable WDM network.

Observation of prolonged power transients in a reconfigurable all optical network

We observe power transients lasting several seconds in a reconfigurable network including cascaded channel power equalizers and chains of fiber amplifiers in a 1898 km fiber link. Gain clamping of the fiber amplifiers proves effective in suppressing the power transients.
