Many networks are designed and operationally drive by the configuration and management of features supporting applications and use cases. For network engineering to catch up to the rest of the operational world, it needs to move rapidly towards data driven management based on a solid understanding of the underlying protocols and systems. Brooks Westbrook joins Tom Amman and Russ White to discuss the data driven lens in this episode of the Hedge.
