We present simulation results of an ultrafast all-optical router and a technique for separating the clock synchronization pulse from an incoming optical time division multiplexed data packet, based on all optical switches employing optical feedback. Three terahertz optical asymmetric demultiplexers (TOADs) have been used to model a 1x2 router. Simulation results show that synchronization betwee...
Growing demands for bandwidth have stimulated the development of high–speed optical shared media networks. All-optical packet based networks offer the potential for high speed and flexible routing. In such systems all optical routers, which overcome the bottleneck of optoelectronic conversion, play an important role. A novel optical router, which uses a terahertz optical asymmetric demultiplexe...
This paper investigates comprehensive operation and experimentation of an all-optical packet switching router with optical label swapping and reamplification and reshaping (2R) regeneration, capable of multihop operation and Internet protocol (IP)client interoperability. In particular, the experiment demonstrates successful packet switching and transport up to 11 hops with 10 9 bit-error rate a...
The paper proposes an all-optical 1×M router architecture based on pulse-positionmodulation header processing (PPM-HP) scheme for packet routing in all-optical highspeed wavelength division multiplexing (WDM) packet switching network. The router is mainly comprised of all-optical clock extraction, pulse-position-modulation header extraction, continuous-wave (CW) sources, wavelength conversion m...
The paper describes research progress in technologies and architectures that give hope to deliver truly transparent switching of optical packets. The importance of all-optical packet switching/routing for convergent next generation transport network and in particularly, for QoS packet transfer in core of future generation wireless networks is pointed out. Generic photonic packet switch/router a...
This paper proposes a new energy management framework for an IP over WDM network. A key constraint of our architecture is to maintain the logical IP topology while saving energy by infrastructure sleeping and virtual router migration. Since the traffic in a network typically has a regular diurnal pattern based on people’s activities, some virtual routers can be moved to a smaller set of physica...
Optical network uses a tool for routing which is called Latin router. These routers use particular algorithms for routing. In this paper, we present algorithm for configuration of optical network that is optimized regarding previous algorithm. We show that by decreasing the number of hops for source-destination in lightpath number of satisfied request is less. Also we had shown that more than s...
To accommodate the explosive packet-based data traffic in WDM networks, intelligent optical routing and switching are required in optical transport networks. Optical multiprotocol label switching networks emerged to meet this demand. In this paper, different schemes for implementing an OMPLS network are introduced. An optical MPLS network using OOC/wavelengths as labels is proposed. Based on an...
