We overview in this paper the buffer management and scheduling issues and draw upon published work to illustrate the possible alternatives of GFR implementation. Performance evaluation has also been done on ATM-GFR’s buffer management algorithms and scheduling algorithms. The simulation results have shown that two-static-threshold-buffermanagement and per-VC-buffer management give the best perf...

Among the various categories of ATM (Asynchronous Transfer Mode) service, ABR (Available Bit Rate) and UBR (Unspecified Bit Rate) have been introduced to support data traffic (such as TCP). GFR (Guarantee Frame Rate) is the current proposed ATM service to provide better performance for data traffic over ATM. The aim of this paper is two-folded. Firstly, we characterise the major research issues...

Switch and router architectures employing a shared buffer are known to provide high throughput, low delay, and high memory utilization. Superior performance of a shared-memory switch compared to switches employing other buffer strategies can be achieved by carefully implementing a buffer-management scheme. A buffer-sharing policy should allow all of the output interfaces to have fair and robust...

We study photonic packet switching architecture that enables high node throughput and provides priority services. While an ultra-high-speed address-lookup capability can be realized in the optical domain for a photonic packet switch, the optical buffer must be managed in the electrical domain. In this paper, we propose a photonic buffer architecture that can support prioritized buffer managemen...
