With the advanc es in server technology, and the advent of fast Gigabit networks, it has become possible to support multi-media applications. To support the requirements for the transmission of isochronous data, the network must provide service guarantees to connections, including minimum bandwidth

and distributed algorithm based on the cost function to divide the end-to-end guaranteed QoS requirements into local QoS requirements which are then mapped into local resource requirements. The algorithm operates in three phases. In the first phase, the nodes in the selected route give the information about

Abstract. In this paper we present the architecture and implementation of a hardware NIC scheduler to guarantee QoS on servers for high speed LAN/SAN. Our proposal employs a programmable logic device based on an FPGA in order to store and update connection states, and to decide what data stream

Guaranteed QoS Synthesis (GQS) is a distributed measurement-based admission control scheme. It is designed as a simple and scalable approach to providing strong service guarantees using bulk packet congestion marking across a core network region. We describe the operation and performance of GQS

for QoS support, without increasing queue requirements. The provided results show that the new switch architecture is able to guarantee QoS levels without any degradation due to congestion situations. Index Terms—High-speed interconnection networks, quality of service, congestion management. Ç 1

desired QoS, out of which bandwidth is the most important constraint. The efficient routing algorithm should have low computational complexity, high network utilization and low call blocking percentage. This paper proposes a new Bandwidth guaranteed QoS routing algorithm based on MPLS networks

Abstract—In wireless networks, power allocation is an effective technique for prolonging network lifetime, achieving better quality-of-service (QoS), and reducing network interference. However, these benefits depend on knowledge of the channel state information (CSI), which is hardly perfect

Abstract — Providing guaranteed quality of service (QoS) with efficient bandwidth utilization over wireless fading channels is challenging. In this paper, we derive the throughput, the packet loss rate and the average delay of an end-to-end wireless link, where the transmitter relies on adaptive

-router interaction scheme in order to achieve a guaranteed level of quality of service (QoS). This paper discusses the task for defining of the roles and the functional dependencies between the routers and the packets as a common problem in the flow of creation and improvement of QoS architectures.

and low channel utilization. To guarantee the QOS of voice service not to be affected by the introduction of GPRS.
