Sustainable load of fibre delay line buffers

Performance Analysis of Optical Fibre Delay Line Buffers and DOCSIS Cable Modem Networks

Online Sorting Buffers on Line

We consider the online scheduling problem for sorting buffers on a line metric. This problem is motivated by an application to disc scheduling. The input to this problem is a sequence of requests. Each request is a block of data to be written on a specified track of the disc. The disc is modeled as a number of tracks arranged on a line. To write a block on a particular track, the scheduler has ...

Offline Sorting Buffers on Line

We consider the offline sorting buffers problem. Input to this problem is a sequence of requests, each specified by a point in a metric space. There is a “server” that moves from point to point to serve these requests. To serve a request, the server needs to visit the point corresponding to that request. The objective is to minimize the total distance travelled by the server in the metric space...

On Packet Scheduling Algorithm for WDM-based Photonic Packet Switch with Fiber Delay Line Buffers

In this paper, we evaluate the performance of the photonic packet switch architecture to which packet scheduling algorithms is applied with fiber delay line buffers which function as the shared buffer. Since, in a shared buffer type switch, a void space introduces unacceptable performance degradation when high traffic load conditions, we propose a void space reduction method to resolve the prob...

Packet Scheduling for WDM Fiber Delay Line Buffers in Photonic Packet Switches

In this paper, we comparatively evaluate two photonic packet switch architectures with WDM-FDL buffers for synchronized variable length packets. The first one is an output buffer type switch, which stores packets in the FDL buffer attached to each output port. Another is a shared buffer type switch, which stores packets in the shared FDL buffer. The performance of a switch is greatly influenced...
