Throttle Bandwidth Hogs using QoS (Episode 3) Learning Happy Hour

Nobody appreciates a data glutton! In this episode, Jason & Mitch show you how to spot bandwidth hogs and how to throttle them using a Palo Alto Networks NGFW. If QoS is new to you, there is a background segment called the QoS High Jump which is a deep dive into what QoS is, how it works, and why it is needed. Make it your New Years resolution to learn about QoS by watching this episode of the Learning Happy Hour!
