The application of photonic technologies to packet switching offers the potential of very large switch capacity in the terabit per second range. The merging of packet switching with photonic technologies opens up the possibility of packet switching in transparent photonic media, in which packets remain in optical form without undergoing optoelectronic conversion. This paper reviews recent work ...

A deadlock in a packet switching network is state which one or more messages have not yet reached their target, cannot progress any further. We formalize three different notions of the context networks, to we refer as global, local and weak deadlock. establish precise relations between these notions, prove they characterize sets deadlocks. Moreover, implement checking freedom networks using sym...

In this paper, packet loss probability performance in cell-based and packet-based switches with finite Input Queues (IQ) and iLPF scheduling algorithm are analysed. This algorithm has been proposed as a practical scheduling algorithm to achieve 100% throughput in cell-based switches. The scheduling algorithm is implemented in three cases: cellbased (CB-iLPF) switching, packet-based (PB-iLPF) sw...

In current switching systems, all packets are divided into equal-sized cells before being scheduled. This is because of the fact that cell-based scheduling is easier to be implemented in hardware. In this paper, we consider the case in which the switch does not split packets and the scheduling is done over the whole packets. In this paper, we classify packet-based scheduling algorithms into wai...

This work introduces a significant improvement for optical packet switching network based on OC processing. The key point of this method is the generalization of the optical label switching concept to forward optical packet without label swapping and O/E/O procedure. Our proposed method simplifies the design of switch devices in optical domain and packet forwarding process which speeds up packe...

First, we will discuss the limitations and difficulties of MPλS, and we will address that the photonic packet switching will be an ultimate solution to solve the problems of MPλS. Next, we will focus on the OC-based photonic packet switching. The advantages of OC-based photonic packet switching include ultrafast photonic label processing capability, optical buffering using WDM fiber delay lines...
