Zero-touch provisioning

From HandWiki
Short description: Networking concept

Zero-touch provisioning (ZTP), or zero-touch enrollment,[1] is the process of remotely provisioning large numbers of network devices such as switches, routers and mobile devices without having to manually program each one individually.[2] The feature improves existing provisioning models, solutions and practices in the areas of wireless networks, (complex) network management and operations services, and cloud based infrastructure services provisioning.[3]

ZTP saves configuration time while reducing errors.[2] The process can also be used to update existing systems using scripts.[2] Research has shown that ZTP systems allow for faster provisioning versus manual provisioning.[4] The global market for ZTP services was estimated to be $2.1 Billion in 2021.[5]

In April 2019, the Internet Engineering Task Force submitted RFC 8572 Secure Zero Touch Provisioning (SZTP) as an Internet standard.[6]

Applications

One application of the technology is to improve delivery of cloud computing services.[7] The concept has been particularly influential for information technology when paired with mobile device management.[8] Repetitive processes that can be automated and streamlined include configuring settings; collecting inventory details; deploying apps; managing licenses; and implementing security policy, including password management and wiping remote devices.[9]

System architecture

A basic ZTP system requires a network device that supports ZTP, a server that supports Dynamic Host Configuration Protocol (DHCP) or Trivial File Transfer Protocol (TFTP), and a file server.[2] When a ZTP-enabled device is powered on, the device's boot file sets up configuration parameters. A switch then sends a request using DHCP or TFTP to get the device's configuration file from a central location. The file then runs and configures ports, IP addresses and other server parameters for each location.[2]

Similar concepts

A similar concept is the zero-touch network, which integrates zero-touch provisioning with automation, artificial intelligence and machine learning.[8]

Standards activity

In December 2017, the European Telecommunications Standards Institute (ETSI) formed the Zero-touch network and Service Management group (ZSM) to accelerate development and standardization of the technology.[10] In the summer of 2019, the group published a series of documents defining ZSM requirements, reference architecture and terminology.[10]

In April 2019, the Internet Engineering Task Force submitted RFC 8572 Secure Zero Touch Provisioning (SZTP) as an Internet standard.[6]
