TLDR
Various priority queueing strategies characterized mainly by different degrees of resource sharing and a general system model for performance evaluation are introduced and performance comparisons and design tradeoffs are addressed.Abstract:
The problem of furnishing an asynchronous transfer mode (ATM) based broadband-ISDN (B-ISDN) with two bearer services supporting different grades of transfer quality is addressed. The focus is on priority bandwidth and buffer management in the ATM communications nodes (switches, multiplexers or concentrators, and expanders) in the context of a multichannel network architecture. Detailed queueing analyses and simulations and results are provided to evaluate the differentiation between traffic classes that can be achieved by different strategies. The implementation complexity of the different schemes is discussed. Various priority queueing strategies characterized mainly by different degrees of resource sharing and a general system model for performance evaluation are introduced. Performance comparisons and design tradeoffs are addressed. >read more

Proportional differentiated services, part II: loss rate differentiation and packet dropping
TL;DR: This paper proposes and evaluates two dropping mechanisms that closely approximate the proportional loss rate differentiation model and examines the coupled effect of delay and loss rate proportional differentiation on the throughput of bulk-transfer TCP connections.

Observer-based fuzzy adaptive stabilization of uncertain switched stochastic nonlinear systems with input quantization
TL;DR: The proposed quantized output feedback control scheme cannot only guarantee the boundedness of signals but also make the output of the system converge to a small neighborhood of the origin.

Dynamic queue allocation and de-allocation
TL;DR: In this article, a dynamic queue allocation and de-allocation mechanism for managing traffic flowing through a switching node is proposed, in which if a packet matches conditions of a particular QoS policy rule, a determination is made as to whether a queue associated with the matched policy rule exists on an egress port that is to forward the packet.

Space priority management in a shared memory ATM switch
A.K. Choudhury,E.L. Hahne +1 more
TL;DR: This work studies the hierarchical shared memory ATM switch architecture in which the queues for all the switch output ports share space flexibly in a common buffer, and investigates various ways to manage space priorities in the shared memory.

Dynamic queue length thresholds for multiple loss priorities
TL;DR: This paper proposes, analyzes, and simulates several ways of incorporating loss priorities into the Dynamic Threshold scheme, and recommends the scheme OWA, which gives some buffers and bandwidth to every priority class at every port.

New directions in communications (or which way to the information age
TL;DR: This article outlined some of the key elements of an integrated network technology, capable of supporting voice, data, and video communication and having the flexibility to accommodate new services as the need arose, and identified Integrated switching architectures, generalized connection signaling protocols, quality-of-service, multicast switching, and routing were all identified as key challenges to be addressed.

Flow Control: A Comparative Survey
Mario Gerla,Leonard Kleinrock +1 more
TL;DR: Flow control can be exercised at various levels in a packet network: hop level, entry-to-exit level, network access level, and transport level, where the interaction between the different levels is discussed and the most representative techniques are surveyed and compared.
