The "IETF Journal", is an Internet Society publication produced in cooperation with the Internet Engineering Task Force. Our aim is to provide an easily understandable overview of what's happening in the world of Internet standards with a particular focus on the activities of the IETF Working Groups (WG). Each issue of the "IETF Journal" will highlight some of the hot issues being discussed in IETF meetings and in the IETF mailing lists.
