This paper discusses optical-label switching and an experimental demonstration of high-speed all-optical packet switching with all-optical label-swapping capabilities. The subcarrier optical-label content was optically extracted and compared against the forwarding table, which induced packet forwarding as well as label-swapping decisions. The alloptical label processing technique was immune fro...

Optical packet switching has been researched for about two decades, but it has not been deployed in commercial networks yet. Nonetheless, the research on optical packet switching continues as it promises to perform better than electronic hardware. We report on the established results of optical packet switching, and examine the reasons for its current state.

The field of computer communication networks has grown very rapidly in the past few years. One way to communicate is viamultiple access broadcast channels. A new class of random access schemes referred to as the Mp-persistent CSMA scheme is proposed. It incorporates the nonpersistent CSMA scheme and l-persistent CSMA scheme, both slotted and unslotted versions, as its special cases with p=O and...

Future networks will require very high throughput, carrying dominantly data-centric traffic. The role of Photonic Networks employing all-optical systems will become increasingly important in providing scalable bandwidth, agile reconfigurability, and low-power consumptions in the future. In particular, the self-similar nature of data traffic indicates that packet switching and burst switching wi...

In this letter, we study the blocking probabilities in an asynchronous optical packet/burst switching system with full wavelength conversion. Most of the existing work use Poisson traffic models that is well-suited for an infinite population of users. In this letter, the optical packet traffic arriving at the switching system is modeled through a superposition of a finite number of identical on...

Operation without packet alignment of an all-optical packet switch is proposed and predicted feasible through a detailed trafic analysis. Packet alignment units are eliminated resulting in a simple switch architecture while optimal traffic perfarmancc is maintained through t ~ i e ~ e x ~ b i ~ ~ ~ ~ r o v ~ d e d by WDM.

This paper covers new optical packet switching router technologies, system architectures, and the future photonic Internet. In particular, we will discuss all-optical label switching routers scalable to 42 Petabit/sec switching capacity, experimental demonstrations of 11 hop cascaded operation, and a 477 km fiber link field trial. Introduction Optical packet switching routers allow integration ...

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...

A packet-switching algorithm specifies the actions of the nodes in order to deliver packets in the network. A packet-switching algorithm is universal if it applies to any network topology and for any batch communication problem on the network. A long standing open problem has concerned the existence of a universal packet-switching algorithm with near optimal performance guarantees for the class...
