Cisco 2019 Software Defined Networking in Datacenter - ACI Solutions

Overview:
The Cisco Application Centric Infrastructure Fabric (ACI) fabric includes Cisco Nexus 9000 Series switches with the APIC to run in the leaf/spine ACI fabric mode. These switches form a “fat-tree” network by connecting each leaf node to each spine node; all other devices connect to the leaf nodes. The APIC manages the ACI fabric. The recommended minimum configuration for the APIC is a cluster of three replicated hosts. The APIC fabric management functions do not operate in the data path of the fabric.

Wireless Technology Will Evolve in 2020

1. Wi-Fi’s New 6 GHz Spectrum

“The 6 GHz band can help drive the next generation of Wi-Fi, and I am optimistic that we will be able to make it available for unlicensed use in 2019.” Said by FCC Chairman

2. Passpoint

Wi-Fi CERTIFIED Passpoint® is an industry-wide solution to streamline network access in Wi-Fi hotspots and eliminate the need for users to find and authenticate a network each time they connect. In Wi-Fi networks that do not support Passpoint®, users must search for and choose a network, request the connection to the access point (AP), and re-enter authentication credentials each visit to gain access to a hotspot location, such as a restaurant, stadium, airport, or hotel. Passpoint automates the entire process, enabling a seamless connection between Wi-Fi hotspot networks and mobile devices, all while delivering enterprise-level security.
