Quality of service (QoS) is receiving strong attention due to its key role in distributed multimedia computing. QoS is not a new concept, being usually employed in the domain of computer networks to specify a set of parameters typically assigned to transport connections. As a rule, QoS is established through negotiation between service users and providers. The process of negotiation is simple if the resources are managed by a centralized entity (e.g. an operating system) or by a set of… 

QoS agency: an agent-based architecture for supporting quality of service in distributed multimedia systems

This paper describes a partial implementation of the proposed architecture using well accepted standards such as CORBA (Object Management Group's Common Object Request Broker Architecture), RTP (Internet's Real Time Protocol) and the Orbix family from Iona.

The architecture proposed in the paper helps build an efficient link between a user and the resource providers and implements the mobile agent technology and the concept behind the logical disk interface by clearly separating QoS negotiation and resource management.

A Multiagent System Architecture for Quality of Service Management in Distributed Multimedia Systems

The performance of computer systems relies on several factors and as fluctuations and degradations are inherent part of any heterogeneous system, QoS maintenance and adaptation become crucial parts of end-to-end QoS provision.

Mobile Agent Coordination for Distributed Network Management

This paper describes the MARS coordination architecture for mobile agents, based on the definition of programmable tuple spaces associated with the network nodes: mobile agents can access the local resources and services via the tuple space, thus adopting a standard and high-level interface.

Network Management based on Mobile Agents using Programmable Tuple Spaces

The MARS coordination architecture, based on programmable Linda-li ke tuple spaces, increases flexibilit y and permits the definition of application specific policies to rule the accesses of mobile agents to local network resources and services.

Design and Implementation of a Distributed Agent Delivery System

The goals, design and implementation of a particular multilingual mobile agent development kit, the Distributed Agent Delivery System (DADS), which supports multiple agent languages types, and is deemed sufficiently lightweight to be deployed in performance-sensitive environments.

Policy-Based Service Provisioning and Users Management Using Mobile Agents

This paper presents in this paper a policy-based management architecture for the provisioning of services to users using mobile agents based on the notion of a domain that supports mapping polices from high level to network ones.

Design of a Mobile Agent-Based Workflow Management System

This paper proposes an efficient design strategy for a mobile agent-based '2-tier distributed workflow server architecture', 'process execution structure through hierarchical delegation' and 'introduction of a non-trivial delegation model' and shows the effectiveness of the method by evaluating performance and scalability through GSPN simulation.

Electronic contract negotiation as an application niche for mobile agents

This paper presents contract negotiation, an example of an application that can potentially take full advantage of mobile agents, and an introduction to a mobile agent system being developed at Hamburg University that can be used to implement contract negotiation.



On distributed multimedia presentational applications: functional and computational architecture and QoS negotiation

The concept of QoS interfaces is introduced in order to handle the QoS negotiation in a general and generic way within the framework of the Reference Model of Open Distributed Processing.

An Approach to Quality of Service Management for Distributed Multimedia Applications

This paper deals with QoS management for multimedia applications by taking remote access to multimedia database as a case study, and a basicQoS management architecture for multimedia Applications is presented.

A Multimedia Enhanced Transport Service in a Quality of Service Architecture

An overview of the QoS-A, which incorporates the notions of flow, service contract and flow management, is provided and the role of a multimedia enhanced transport service (METS) is focused on to show how QoS levels contracted by the transport service user can be assured in the context of the authors' experimental local ATM environment.

The QOS Broker

The QOS Broker is a software engineering technique that uses this principle to arrange for the delivery of end-to-end quality of service in distributed multimedia systems.
