—We propose a sublambda traffic-grooming scheme on wavelength-division-multiplexing ring networks, named optical burst transport. The network protocol and architecture are designed to support dynamic bandwidth allocation, which is more reasonable for bursty data traffic. To verify our network protocol and architecture, we build a testbed which supports… (More)
Optical Burst Transport network is a novel WDM ring architecture for Metropolitan Area Networks (MAN). It leverages the advantages of optical burst switching and WDM rings, while using a token-based medium access scheme. In this paper, we investigate protection together with spatial reuse property. Specifically we show how protection in OBT can be different… (More)
An access network using a centralized light sources (CLS) and multi mode fiber (MMF) is proposed and verified using BER measurements. Results show that we can implement CLS based PON using currently existing MMF infrastructure.
Optical Burst Transport networks employ burst transmission in WDM ring architectures and are promising candidates for MANs. We investigate QoS differentiation in OBT, and compare its performance to IEEE 802.17 Resilient Packet Ring (RPR) Standard.
