The Symposium on Operating Systems Principles (SOSP), organized by the Association for Computing Machinery (ACM), is one of the most prestigious single-track academic conferences on operating systems. [1] [2] [3] [4] [5]
Before 2023, SOSP was held every other year, alternating with the conference on Operating Systems Design and Implementation (OSDI); starting 2024, SOSP began to be held every year. The first SOSP was held in 1967. It is sponsored by the ACM's Special Interest Group on Operating Systems (SIGOPS).
The inaugural conference was held in Gatlinburg, Tennessee on 1–4 October 1967 at the Mountain View Hotel. [6] There were fifteen papers in total, of which three presentations were in the Computer Networks and Communications session. [7] Larry Roberts presented his plan for the ARPANET, a computer network for resource sharing, which at that point was based on Wesley Clark's proposal for a message switching network. [8] [9] [10] Jack Dennis from MIT discussed the merits of a more general data communications network. Roger Scantlebury, a member of Donald Davies' team from the UK National Physical Laboratory, presented their research on packet switching in a high-speed computer network, and referenced the work of Paul Baran. [11] [12] [13] At this seminal meeting, [14] [15] [16] Scantlebury proposed packet switching for use in the ARPANET and persuaded Roberts the economics were favorable to message switching. [17] [18] [19] [20] [21] The ARPA team enthusiastically received the idea and Roberts incorporated it into the ARPANET design. [22] [23] [24] [25]
In total, 29 conferences have been held, seven of which were outside the USA. The first conference held outside the USA was in Saint-Malo, France in 1997. Other countries to have hosted the conference are Canada, the UK, Portugal, China and Germany. [26]
From 1967 to 2023, the conferences were held every two years, with the first SOSP conference taking place in Gatlinburg, Tennessee. [26] Beginning in 2024, SOSP the conference is held every year.

The history of the Internet has its origin in the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
In telecommunications, packet switching is a method of grouping data into short messages in fixed format, i.e. packets, that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an operating system, application software, or higher layer protocols. Packet switching is the primary basis for data communications in computer networks worldwide.
This article presents a detailed timeline of events in the history of computing from 1950 to 1979. For narratives explaining the overall developments, see the history of computing.
In telecommunications, message switching involves messages routed in their entirety, one hop at a time. It evolved from circuit switching and was the precursor of packet switching.
The end-to-end principle is a design framework in computer networking. In networks designed according to this principle, guaranteeing certain application-specific features, such as reliability and security, requires that they reside in the communicating end nodes of the network. Intermediary nodes, such as gateways and routers, that exist to establish the network, may implement these to improve efficiency but cannot guarantee end-to-end correctness.
The National Physical Laboratory (NPL) is the national measurement standards laboratory of the United Kingdom. It sets and maintains physical standards for British industry.
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency of the United States Department of Defense.
Leonard Kleinrock is an American computer scientist and Internet pioneer. He is Distinguished Professor Emeritus of Computer Science at UCLA's Henry Samueli School of Engineering and Applied Science. Kleinrock made several important contributions to the field of computer science, in particular to the mathematical foundations of data communication in computer networking. He has received numerous prestigious awards.
Donald Watts Davies, was a Welsh computer scientist and Internet pioneer who was employed at the UK National Physical Laboratory (NPL).
Paul Baran was an American-Jewish engineer who was a pioneer in the development of computer networks. He was one of the two independent inventors of packet switching, which is today the dominant basis for data communications in computer networks worldwide, and went on to start several companies and develop other technologies that are an essential part of modern digital communication.
Wesley Allison Clark was an American physicist who is credited for designing the first modern personal computer. He was also a computer designer and the main participant, along with Charles Molnar, in the creation of the LINC computer, which was the first minicomputer and shares with a number of other computers the claim to be the inspiration for the personal computer.
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. In later years the IMPs were made from the non-ruggedized Honeywell 316 which could handle two-thirds of the communication traffic at approximately one-half the cost. An IMP requires the connection to a host computer via a special bit-serial interface, defined in BBN Report 1822. The IMP software and the ARPA network communications protocol running on the IMPs was discussed in RFC 1, the first of a series of standardization documents published by what later became the Internet Engineering Task Force (IETF).
Larry Roberts was an American computer scientist and Internet pioneer.
IEEE Internet Award is a Technical Field Award established by the IEEE in June 1999. The award is sponsored by Nokia Corporation. It may be presented annually to an individual or up to three recipients, for exceptional contributions to the advancement of Internet technology for network architecture, mobility and/or end-use applications. Awardees receive a bronze medal, certificate, and honorarium.
The NPL network, or NPL Data Communications Network, was a local area computer network operated by a team from the National Physical Laboratory (NPL) in London that pioneered the concept of packet switching.
Roger Anthony Scantlebury is a British computer scientist and Internet pioneer who worked at the National Physical Laboratory (NPL) and later at Logica.
The International Network Working Group (INWG) was a group of prominent computer science researchers in the 1970s who studied and developed standards and protocols for interconnection of computer networks. Set up in 1972 as an informal group to consider the technical issues involved in connecting different networks, its goal was to develop an international standard protocol for internetworking. INWG became a subcommittee of the International Federation for Information Processing (IFIP) the following year. Concepts developed by members of the group contributed to the Protocol for Packet Network Intercommunication proposed by Vint Cerf and Bob Kahn in 1974 and the Transmission Control Protocol and Internet Protocol (TCP/IP) that emerged later.
The Protocol Wars were a long-running debate in computer science that occurred from the 1970s to the 1990s, when engineers, organizations and nations became polarized over the issue of which communication protocol would result in the best and most robust networks. This culminated in the Internet–OSI Standards War in the 1980s and early 1990s, which was ultimately "won" by the Internet protocol suite (TCP/IP) by the mid-1990s when it became the dominant protocol suite through rapid adoption of the Internet.
David Corydon Walden was an American computer scientist and Internet pioneer who contributed to the engineering development of the ARPANET, a precursor of the modern Internet. He specifically contributed to the Interface Message Processor, which was the packet switching node for the ARPANET. Walden was a contributor to IEEE Computer Society's Annals of the History of Computing and was a member of the TeX Users Group.
The most prestigious conferences (SOSP, OSDI) have had such papers in each of last few editions.
Roberts' proposal that all host computers would connect to one another directly ... was not endorsed ... Wesley Clark ... suggested to Roberts that the network be managed by identical small computers, each attached to a host computer. Accepting the idea, Roberts named the small computers dedicated to network administration 'Interface Message Processors' (IMPs), which later evolved into today's routers.
Thus the set of IMP's, plus the telephone lines and data sets would constitute a message switching network
W. Clark's message switching proposal (appended to Taylor's letter of April 24, 1967 to Engelbart)were reviewed.
Roberts also learned from Scantlebury, for the first time, of the work that had been done by Paul Baran at RAND a few years earlier.
[Scantlebury said] Clearly Donald and Paul Baran had independently come to a similar idea albeit for different purposes. Paul for a survivable voice/telex network, ours for a high-speed computer network. ... We referenced Baran's paper in our 1967 Gatlinburg ACM paper. You will find it in the References. Therefore I am sure that we introduced Baran's work to Larry (and hence the BBN guys).
Historians credit seminal insights to Welsh scientist Donald W. Davies and American engineer Paul Baran
It was a seminal meeting
they lacked one vital ingredient. Since none of them had heard of Paul Baran they had no serious idea of how to make the system work. And it took an English outfit to tell them. ... Larry Roberts paper was the first public presentation of the ARPANET concept as conceived with the aid of Wesley Clark ... Looking at it now, Roberts paper seems extraordinarily, well, vague.
Scantlebury and his companions from the NPL group were happy to sit up with Roberts all that night, sharing technical details and arguing over the finer points.
Roger actually convinced Larry that what he was talking about was all wrong and that the way that NPL were proposing to do it was right. I've got some notes that say that first Larry was sceptical but several of the others there sided with Roger and eventually Larry was overwhelmed by the numbers.
the ARPA network is being implemented using existing telegraphic techniques simply because the type of network we describe does not exist. It appears that the ideas in the NPL paper at this moment are more advanced than any proposed in the USA
Larry Roberts presented a paper on early ideas for what was to become ARPAnet. This was based on a store-and-forward method for entire messages, but as a result of that meeting the NPL work helped to convince Roberts that packet switching was the way forward.
The NPL group influenced a number of American computer scientists in favor of the new technique, and they adopted Davies's term "packet switching" to refer to this type of network. Roberts also adopted some specific aspects of the NPL design.
Roberts was quick to latch on to a good idea. 'Suddenly I learned how to route packets,' he later said of the Gatlinburg conference.
America's Advanced Research Project Agency (ARPA), and the ARPANET received his network design enthusiastically
