With ever-increasing demand for bandwidth, both optical packet switching and optical burst switching are proposed as alternatives to increase the capacity of optical networks in the future. In these packet-based switching techniques, Fiber Delay Lines are used to avoid contention between packets on a single wavelength. The involved scheduling algorithms ...

With ever-increasing demand for bandwidth, optical packet/burst switching is proposed to utilize more of the available capacity of optical networks in the future. In these packet-based switching techniques, packet contention on a single wavelength is resolved effectively by means of Fiber Delay Lines. The involved scheduling algorithms are typically designed ...

This letter focuses on the waiting time of customers in a single-server queueing system, served according to one of two well-known scheduling disciplines, Random-Order-of-Service (ROS) and First-Come-First-Served (FCFS). Arrivals are modeled with a Markov-Modulated Poisson Process (MMPP); service times are exponential. For two basic settings, ROS outperforms FCFS by several ...

As Internet traffic will further increase in coming years, the current optical network infrastructure will have to grow along in terms of capacity. To this end, optical packet/burst switching have been proposed, allowing more efficient use of the available fibre capacity. To resolve packet contention in the involved optical switches, ...

With ever-increasing demands for bandwidth, optical packet/burst switching is used to utilize more of the available capacity of optical networks. In existing prototypes of optical switches, packet contention is resolved by combining time and wavelength multiplexing by means of fiber delay lines and wavelength converters. Although optical switches dissipate less ...

In optical packet/burst switching, fibre-loop optical buffers provide a compact and effective means of contention resolution. In case of fixed packet length, the involved loop length is typically chosen matched (equal to the packet length), and the loops are arranged in parallel, constituting a single-stage buffer. In this contribution, we ...

Running multiple programs on a processor aims at increasing the throughput of that processor. However, defining meaningful throughput metrics in a simulation environment is not as straightforward as reporting execution time. This has led to an ongoing debate on what forms a meaningful throughput metric for multiprogram workloads. We present ...

Optical switching (optical packet switching, optical burst switching, and others) provides alternatives to the current switching in backbone networks. To switch optically, also packet buffering is to be done optically, by means of fiber delay lines (FDLs). Characteristic of the resulting optical buffer is the quantization of possible delays: Only ...

In call centers, call blending consists in the mixing of incoming and outgoing call activity. Artalejo and Phung-Duc recently provided an apt model for such a setting, with a two way communication retrial queue. However, by assuming a classical (proportional) retrial rate for the incoming calls, the outgoing call activity ...

For current backbone networks, the capacity limit is not fiber throughput (> 10 Tbit/s per fiber), but rather, switching speed. Optical switching (Optical Packet Switching, Optical Burst Switching, and others) provides a viable alternative, relying on Fiber Delay Lines (FDLs) for buffering. The main feature of such a buffer is ...

Optical packet switching and burst switching provide future-proof alternatives to the current electronic switching in the backbone. To resolve burst (or packet) contention, fiber delay lines are put to use as buffers, as vital part of a channel and delay selection (CDS) algorithm. In case no void-filling is applied, earlier ...

DSL aggregation networks are evolving to the standard platform for the delivery of multimedia services such as television and network based personal video recording. These multimedia services introduce large challenges for network operators as they are sensitive to packet loss. Therefore, admission control mechanisms are required to avoid congestion caused ...

Providing a photonic alternative to the current electronic switching in the backbone, optical packet switching (OPS) and optical burst switching (OBS) require optical buffering. Optical buffering exploits delays in long optical fibres; an optical buffer is implemented by routing packets through a set of fibre delay lines (FDLs). Previous studies ...

Novel switching approaches like Optical Burst/Packet Switching have buffering implemented with Fiber Delay Lines (FDLs). Previous performance models of the resulting buffer only allowed for solution by numerical means, and only for one time setting: continuous, or discrete. With a Markov chain approach, we constructed a generic framework that encompasses ...

Providing a photonic alternative to the current electronic switching in the backbone, optical burst switching (OBS) requires that also the buffering is implemented optically, with a set of fiber delay lines (FDLs). Previous performance studies pointed out that the resulting optical buffer suffers additional performance loss (when compared to RAM), ...

In novel switching approaches such as Optical Burst Switching, the involved buffers can only provide a degenerate waiting room, with delays restricted to multiples of a basic value, the granularity. Although the resulting performance loss was already studied analytically, previous work is either limited by the assumption of independent arrivals, ...

Optical Burst Switching proposes a future-proof alternative to the current electronic switching in the backbone. The involved optical buffers are implemented with a set of Fiber Delay Lines, and suffer serious performance loss, when compared to RAM. Various existing models trace this loss, but either lack generality, accuracy, or effectiveness. ...

We investigate the behaviour of an asynchronous optical buffer by means of a continuous-time queuing model. Through a limit procedure, previously obtained results for a discrete-time queuing model are translated to a continuous-time setting. We also show that the same results can be obtained by a direct analysis using Laplace ...
