What's new?

Time to update the Network Time Protocol
The Network Time Protocol (NTP) is a foundational Internet standard that has provided clock synchronization between computer systems since the early 1980s. It was first standardized as RFC 958 in Sept 1984 with several revisions in the following years. Discussions have been ongoing in the NTP working group for a few years now about updating NTPv4 to NTPv5. This update is motivated by lessons learned, ongoing vulnerabilities, and emerging use cases.

Working Groups

Working Groups are the primary mechanism for development of IETF specifications and guidelines. Working Groups are typically created to address a specific problem or to produce one or more specific deliverables (a guideline, standards specification, etc.).

Topics of interest

Automated network management
The IETF is working on standards for automated network management which, as the name implies, aims to improve and make more efficient management of networks as they continue to increase in size and complexity.
The Internet of Things at the IETF
The Internet of Things (IoT) is the network of physical objects or "things" embedded with electronics, software, sensors, actuators, and connectivity to enable objects to exchange data with the manufacturer, operator, and/or other connected devices.
New transport technology
The development of new transport technologies in the IETF provides capabilities that improve the ability of Internet applications to send data over the Internet.
