Optimal buffer control during congestion in an ATM network node
TLDR
Study the problem of optimal buffer space priority control in an ATM network node and three classes of policies that schedule the buffer allocation in some optimal manner are identified.Abstract:
Study the problem of optimal buffer space priority control in an ATM network node. The buffer of a transmission link is shared among the cells of several traffic classes waiting for transmission through the link. When the number of cells to be stored in the buffer exceeds the available buffer space, certain cells have to be dropped. Different traffic classes have different sensitivities to cell losses. By appropriately selecting the classes of cells which are dropped or blocked in case of overflow, one can have the more sensitive classes suffering smaller cell losses. Depending on the control that on the system, three classes of policies are distinguished. In each one, policies that schedule the buffer allocation in some optimal manner are identified. >read more

Queueing analysis of a threshold based priority scheme for ATM networks
Duan-Shin Lee,Bhaskar Sengupta +1 more
TL;DR: A threshold-based priority scheme in which a tuning parameter is used to provide adequate quality of service to real-time traffic while providing the best possible service to the non-real- time traffic is proposed.

Design of a generalized priority queue manager for ATM switches
TL;DR: In this paper, a generalized priority queue manager (GPQM) is proposed to support multiple QoS requirements and achieve fairness in both cell transmission and discarding at the output buffers of an ATM switch.

Effective bandwidth vectors for multiclass traffic multiplexed in partitioned buffer
TL;DR: A traffic model where a single source generates traffic having J (J/spl ges/2) quality of service (QoS) classes, QoS in this case described by a cell loss probability objective /spl epsiv//sub j/ for QoS class j, assuming that class J has the most stringent QoS requirements and class 1 the least.

Applying a New Device in the Optimization of Exponential Queuing Systems
TL;DR: A new definition of the time of transition is provided, which is able to utilize the inductive approach in a manner characteristic of inventory theory, and a policy optimal for all sufficiently small discount factors can be obtained from the usual average cost functional equation without recourse to further computation.

The Knockout Switch: a simple, modular architecture for high-performance packet switching
TL;DR: A new, high-performance packet-switching architecture, called the Knockout Switch, is proposed, which uses a novel concentrator design at each output to reduce the number of separate buffers needed to receive simultaneously arriving packets.

The Knockout Switch: A Simple, Modular Architecture for High-Performance Packet Switching
TL;DR: The Knockout Switch as discussed by the authors uses a fully interconnected switch fabric topology (i.e., each input has a direct path to every output) so that no switch blocking occurs where packets destined for one output interfere with (block or delay) packets going to different Outputs.

Priority management in ATM switching nodes
TL;DR: A comparative performance study is given, indicating the excellent performance characteristics of a simple buffer management scheme called partial buffer sharing, and the introduction of a second bearer capability provides a 10/sup -6/ cell loss rate instead of 10/Sup -10/.
