  • Impressions from the Internet Architecture Board E-Impact Workshop

    The IAB ran an online workshop in December 2022 to begin to explore and understand the environmental impacts of the Internet. The discussion was active, and it will take time to summarise and produce the workshop report – but the topic is important, so we wanted to share some early impressions of the outcomes.

Remembering Bob Braden

  • Alissa CooperIETF Chair

19 Apr 2018

I am writing to share the sad news that Bob Braden has passed away. Bob's contributions to the development of the Internet were extensive.

He was a legendary contributor to the early ARPANET Host-Host protocols for the IBM 360 machines and to TCP/IP early in its development. He was a member of the Internet Architecture Board at its inception and served there for 13 years. He created the End-to-End Task Force which eventually became the IRTF End-to-End Research Group, which he chaired for many years. Together with Joyce Reynolds, Bob exercised careful stewardship over the RFC series after Jon Postel's passing. He was the author of over 60 RFCs including the seminal series of RFCs beginning with RFC 1122, Requirements for Internet Hosts -- Communication Layers.

Bob was known for being particularly thoughtful, constructive, and calm in technical discussions. His friendly demeanor and wry sense of humor were appreciated throughout the community. And he was always willing to work for the good of the Internet.

So many in the IETF community have learned from him, been inspired by his work, and enjoyed his friendship. He will be deeply missed.


  • [1]RFC 1122

    Requirements for Internet Hosts - Communication Layers

    This RFC is an official specification for the Internet community. It incorporates by reference, amends, corrects, and supplements the primary protocol standards documents relating to hosts. [STANDARDS-TRACK]
