Optical Packet Switches

37th European Conference and Exposition on Optical Communications, 2011
The capacity growth of optical networks and a transition towards packet-based traffic has motivated research on optical packet switches. We review recent experiments on optical packet switches and their application to metropolitan and core networks ...

Optical Packet Switching

2009
This chapter provides an outline of the main concepts and issues related to optical packet switching (OPS). The basic network functions required by this paradigm are discussed and references to past and current research on the topic are provided. Optical packet switching is a transport technique that assumes information to be organized in packets ...

Optical Packet Switching and Optical Burst Switching

2020
Optical transmission has long been the established choice for nonwireless data transmission spanning distances longer than a few tens of meters, due to its high bandwidth and electromagnetic noise immunity. Most current high-bandwidth networks are essentially a group of fiber-optic links connected by nodes whose function is to forward incoming data to ...

Packet-switched optical networks

IEEE Micro, 1998
We 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, 1997
Abstract 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, 2000
One 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, 2006
We 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, 2003
The 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, 2001
Wavelength-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,, 2003
Optical 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.
