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

Free registration required

Executive Summary

Building a multiservice network is a strategic initiative that shouldn't be stymied by QoS pitfalls. Juniper Networks designed the EX3200, EX4200 and EX8200 switches to simplify creating a converged infrastructure. The EX Series switches enable enterprises to deliver predictable performance for any combination of traffic with the least possible administrative overhead. By supporting a common set of QoS features from the access layer to the core, Juniper allows enterprises to follow best practices for ensuring consistent end-to-end QoS. For example, robust QoS features in access devices (whether the EX3200 or EX4200) means that network traffic can be classified and policed at the source. Likewise, standard Layer 3 support on all Juniper switch and router platforms means enterprises have the option to use DSCP marking end-to-end.
