Optical packet switching networks

SPIE Proceedings, 2005
Optical 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, 2007
This 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), 2003
A 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.

Buffering in optical packet switches

Journal of Lightwave Technology, 1998
This paper consists of a categorization of optical buffering strategies for optical packet switches, and a comparison of the performance of these strategies both with respect to packet loss/delay and bit error rate (BER) performance. Issues surrounding optical buffer implementation are discussed, and representative architectures are introduced under ...

QoS differentiation in optical packet-switched networks

Computer Communications, 2006
This paper deals with the problem of service differentiation in an optical packet-switched backbone. A QoS-aware network function based on different routing and contention resolution strategies for different classes of service is proposed and analyzed. Contention resolution is performed by using both wavelength and time domains and QoS differentiation ...

TCP Performance in Optical Packet-switched Networks

Photonic Network Communications, 2006
Optical packet assembly is a key function to support inter-working between TCP/IP networks and optical packet-switched networks. It is characterized by the assembly delay and by the segment aggregation needed to form an optical packet. These counter-balancing aspects depend on several environment variables, such as the TCP parameters, the access link ...

Routing techniques in optical packet-switched networks

Proceedings of 2005 7th International Conference Transparent Optical Networks, 2005., 2005
In the last few years research on optical packet-switching has mainly concentrated on issues at the single node level. This paper intends to discuss about the problems arising when the focus is moved towards a network-wide scope. In particular, an overview of routing techniques that may be adopted in an optical packet-switched backbone is presented ...

Multi-Slot Batch-Transfer Optical Packet Switch

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
In optical packet switching, the reconfiguration time of optical switches should only be a small fraction of the packet transmission time for efficient utilization of the bandwidth. This constraint puts a very stringent demand on the switch reconfiguration time as the transmission rate of optical fiber increases.

Optical Packet Switching Meets Mythbusters

Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2011, 2011
Despite twenty years of research, optical packet switching (OPS) struggles to find practical application. We analyze the capabilities and limitations of OPS, and conclude that OPS offers little compared with conventional electronic packet switching.
