QoS is the second-most widely-deployed technology in the enterprise (after routing). Additionally, business requirements for Quality of Service continue to evolve to the point where the biggest barrier to deploying QoS is technical-complexity. However, breakthrough technologies allow for the abstraction of such complexity and the enabling of powerful business-centric policies to be deployed in a significantly simplified manner. This session will be presented in four sections: the first section will overview Cisco's new direction for AVC and QoS; additionally, new technologies, like NBAR2 QoS Attributes, DNS-AS and others will be introduced to show how the QoS toolset continues to expand and allow for more powerful policies than ever before.� The second section will focus on the WAN/IWAN, so as to optimise the use of the most expensive bandwidth in the enterprise; detailed design recommendations will be presented for ASR and ISR routers. The third section will overview campus QoS design, and configurations will be shared for Cisco 3650, 3850, 4500, 6500 and 6800 series switches. The final section will focus on the dominant access-medium in the enterprise, namely the wireless LAN. Wi-Fi networks have several unique and specific QoS constraints, which are critical to address in end-to-end designs. Also, Cisco�s DNA EasyQoS solution will be featured through the session, showing how powerful designs can be deployed at each place in the network with unprecedented simplicity.
