Juniper EX-Series Ethernet Switches: QoS-Enabling the Enterprise - Assuring End-to-End Application Performance

The enterprise network is no longer a data-only transport. It has evolved into a multi-services infrastructure carrying business-critical applications, voice and video streams, and traffic from building automation and other control systems. The emergence of unified communications will further spur the trend toward converged networks. IT's challenge is to ensure predictable performance for all applications and traffic types sharing the IP infrastructure. 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 support a complementary set of QoS mechanisms to ensure consistent, predictable traffic handling end-to-end.
