Packet-switched optical networks
IEEE Micro, 1998We describe a testbed to study both the theoretical aspects and physical implementation issues associated with high-bit-rate, multihop, packet-switched OTDM networks. We have found that using optical time-division-multiplexed (OTDM) techniques can greatly increase the bandwidth of a single-wavelength channel.

CORD: Optical packet-switched network testbed
Fiber and Integrated Optics, 1997Abstract We are implementing and investigating CORD, a 2.5 Gbit/s/λ WDM packet-switched network testbed. CORD features: (i) contention resolution optics (CRO), which consist of optical switches and delay lines to perform all-optical packet contention resolution; (ii) multichannel subcarrier multiplexed (MSCM) signaling to transmit an 80 Mbit/s control ...

Packet switching or optical switching?
IEEE Internet Computing, 2000One of history's main benefits is that it lets us detect trends that help predict the future. Over the past 30 years since the Internet started (1970-2000), many clear trends have emerged. The article very briefly examines the most critical of these trends, the one that led to the creation of the Internet: the packet switching cost trend.

Optical Buffering and Switching for Optical Packet Switching
2006 International Conference on Photonics in Switching, 2006We describe the design and initial results of an all-optical buffered 40 Gb/s packet switch. Dynamic packet forwarding is illustrated and specific attention is directed to buffering. We assess the challenges in meeting the requirements for optical buffering devices. Slow light and delay line buffering approaches are described and several recent results

Design of optical packet switching networks
Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE, 2003The paper considers optical packet switching networks with slotted operation. A general model of network nodes is introduced, based upon a nonblocking switching fabric, and re-circulating fiber delay lines to solve contentions. Given the current large bandwidth availability in optical networks, and the projected limitations of electronic switches, a ...

Techniques for optical packet switching and optical burst switching
IEEE Communications Magazine, 2001Wavelength-division multiplexing appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. Several different technologies have been developed so far for the transfer of data over WDM.

Optical buffering and switching in packet switched optical networks
IEEE AFRICON. 6th Africon Conference in Africa,, 2003Optical packet switching provides the advantages of transparency and the efficient use of the bandwidth provided by WDM on optical transport networks. There are however various impediments to deploying this technology in an all-optical fashion: optical buffering is inefficient, and all-optical signal processing has not been implemented in networks.

Optical packet switching networks
SPIE Proceedings, 2005Optical packet switching techniques have been studied for many years and many feasibility experiments have demonstrated the viability of this technology at different areas of the network. In this paper an analysis of the optical technology potential in different network areas: metro access, metro core and backbone, is carried out.

Adaptive optical label packet switching
SPIE Proceedings, 2007This paper introduces a kind of Adaptive Optical Label Packet Switching (AOLPS) technology. Based on Optical Packet Switching (OPS), AOLPS uses optical label to achieve self-routing, and the size of optical packet is self-adaptive. At the edge nodes, IP packets are fist classified into different first-in-fist-out memories (FIFOs) according to their

Optical switching technologies for fast optical packet switching
Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat. No.02EX551), 2003A survey of optical switching technologies being candidates for an optical packet switched (OPS) network is presented. Switching time range for optical switching fabrics is found through analysis. In light of this, and based on reported switch devices, switching technologies are identified as candidates for OPS.
