QoS-Aware Middleware for Web Services Composition
White Papers Since many available Web services provide overlapping or identical functionality, albeit with different Quality of Service (QoS), a choice needs to be made to determine which services are to participate in a given composite service.

QoS Perspective for Wireless Scenarios
White Papers In particular, telecommunications services are evaluated by a set of parameters called QoS parameters: throughput, delay, jitter, and packet loss. This paper considers that each layer parameters essentially contribute to the global QoS evaluation.

Wireless LAN Medium Access Techniques: QoS Perspective
White Papers Different people and communities perceive and interpret Quality of Services (QoS) in different ways. This paper considers that QoS problem has two major perspectives: network perspective and application/user perspective.

Defining a J2EE Role on Service Component Architecture Components With WebSphere Integration Developer 6.0.1: Applying Quality of Service (QoS) Security Qualifiers to SCA Components
White Papers Service Component Architecture (SCA) lets the user define policy and Quality Of Service (QoS) by abstracting from underlying transports, without requiring programming or changes to the services implementation code.

Juniper EX-Series Ethernet Switches: QoS-Enabling the Enterprise - Assuring End-to-End Application Performance
White Papers The right set of Quality of Service (QoS) tools is critical to meeting this challenge. QoS tools must be sufficiently granular to accommodate a rich mix of traffic types. Network switches and routers deployed at every level in the network must...

QoS Parameters to Network Performance Metrics Mapping for SLA Monitoring
White Papers The most important factor in SLA monitoring is the mapping between QoS parameters and network performance metrics (NPMs). This paper categorizes SLM into seven functions. The paper defines the concept of SLA monitoring in the network management layer.

IP Network Design With End-to-End QoS Constraints: The VPN Case
White Papers The traditional approaches to optimal design and planning of packet networks focus on the network-layer infrastructure, thus neglecting end-to-end Quality of Service (e2e QoS) issues, and Service Level Agreement (SLA) guarantees.
