This paper presents a way of doing IP packet classification at high speed, a critical operation for highcapacity routers. Two hardware designs are presented, both based on simple, standard logic. One goal is that the designs should be inexpensive and simple enough that it is feasible to replicate them on each input port on a router. The first design is for unicast forwarding, based on destinati...

In this paper, we analyze the queueing behaviour of wavelength division multiplexing (WDM) Internet router employing partial buffer sharing (PBS) mechanism with self-similar traffic input. In view of WDM technology in networking, each output port of the router is modelled as multi-server queueing system. To guarantee the quality of service (QoS) in Broadband integrated services digital network ...

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...
