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-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.
