The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17th century to explain how light could be transmitted through a vacuum. more
Digital communications systems always represent a collection of design trade-offs. Maximizing one characteristic of a system may impair others, and various communications services may choose to optimize different performance parameters based on the intersection of these design decisions with the physical characteristics of the communications medium. more
There have been a number of occasions when the Internet Engineering Task Force (IETF) has made a principled decision upholding users' expectations of privacy in their use of IETF-standardised technologies. (Either that, or they were applying their own somewhat liberal collective bias and to the technologies they were working on!) The first major such incident that I can recall is the IETF's response to the US CALEA measures. more
The IETF met in November 2022 in London. Among the many sessions that were held in that meeting was a session of the Decentralised Internet Infrastructure Research Group, (DINRG). The research group's ambitions are lofty: DINRG will investigate open research issues in decentralizing infrastructure services such as trust management, identity management, name resolution, resource/asset ownership management, and resource discovery. more
When I was first advocating home networking at Microsoft, we encountered a problem. The existing systems and applications had implicitly assumed they were inside a safe environment and didn't consider threats from bad actors. Early Windows systems hadn't yet provided file system with access control and other protections though there were some attempts to have separate logins to keep some settings separate. more
The shift from IPv4 to IPv6 has been a protracted and complex process, raising questions about why this transition has been so sluggish despite the depletion of IPv4 addresses more than a decade ago. more
The Internet Society has announced the 2024 Jonathan B. Postel Service Award recipients, honoring Steve Crocker and Xing Li for their pioneering work in advancing the global Internet infrastructure. more
If you operate an Internet Exchange Point (IXP) or are interested in creating one, the Internet Society has a “Sustainable Peering Infrastructure” funding program that is open for applications until this Friday, September 6, 2024... Grant funds from USD $5,000 up to $50,000 are open to all regions and are available to assist in equipment purchases (switches, optic modules, servers, and routers), training, capacity building, and community development. more
