Beschreibung
Network Programmability and Automation, Volume 1, covers designing, implementing, monitoring and operating networks using programmable interfaces on network devices versus the legacy (and soon-to-be obsolete) methods and protocols such as the Command Line Interface (CLI) and Simple Network Management Protocol (SNMP). It discusses the protocols, tools, techniques and technologies upon which Network Programmability is based.
Covering the fundamentals that a network engineer needs to transition to the software and programmability domains, the book opens with an introduction that lays the foundation by discussing the market trends and emerging technologies such as SDN, NFV and Cloud, and how network programmability skills are paramount for aligning oneself with these technologies. It provides network engineers with a solid foundation in Python programming and Linux in the context of network programmability and automation.
