IRTF Research Groups work on topics related to Internet protocols, applications, architecture and technology. The IRTF is managed by the IRTF Chair, in consultation with the Internet Research Steering Group (IRSG). In addition to managing the Research Groups, the IRSG may from time to time hold topical workshops focusing on research areas of importance to the evolution of the Internet, or more general workshops to, for example, discuss research priorities from an Internet perspective.
