Toasternet

Toasternet is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Toasternet rather than just read about it. In short: Toasternets were an early-1990s instantiation of the decentralized Internet, featuring open-standards-based federated services, radical decentralization, ad-hoc routing and consisting of many small individual and collective networks rather than a cartel of large commercial Internet service provider networks.

Key takeaways

  • Toasternet belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Toasternet to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Toasternet from memory before moving on to harder problems.

Reference excerpt

Toasternets were an early-1990s instantiation of the decentralized Internet, featuring open-standards-based federated services, radical decentralization, ad-hoc routing and consisting of many small individual and collective networks rather than a cartel of large commercial Internet service provider networks. Today's community networks and decentralized social networks are the closest modern inheritors of the ethos of the 1991-1994 era Toasternets.

History The first known use of the word was by Robert Ullmann, then active in the Internet Engineering Task Force developing next-generation Internet addressing and routing protocols. He circulated the documents Toasternet Part I (December 1989) and Toasternet Part II (March 1992) on the IETF mailing list, then published RFCs 1475 and 1476 and the "CATNIP" Internet-Draft in June 1993. Early toasternet proponent Tim Pozar described a Toasternet as:

"an Internet-connected computer network built very cheaply so as to have a cost that a small business, school or individual can afford. It has been joking said that these networks are so cheap, you can connect everything in sight, including your toaster. Generally speaking, most Toasternets exist to meet a group's or individual's communications needs, rather than profit as a motive." Pozar, and other early toasternet builders Bill Woodcock and John Gilmore were participants in the cooperative The Little Garden, the first Internet service provider based on the west coast of the United States. Founded and led by Tom Jennings, The Little Garden (named for the Vietnamese restaurant where its foundational meetings were held) was an Internet service provider network built between 1992 and 1996 in the toasternet ethos, and consisting of constituent toasternet members; some individual, and some collective. Many of the initial Little Garden members went on to become founding members of Packet Clearing House, the not-for-profit which now supports core Internet infrastructure globally, but still continues to promulgate the toasternet values of collaborative competition and "permissionless" new market entry. Writing contemporaneously in Wired, Jonathan Steuer said,

"Toasternets are not actually comprised of toasters and network cable. Rather, the term "toasternet" refers generically to small computer networks built out of cheap and readily available parts. Unlike commercial network service providers, who are motivated primarily by their bottom line, most toasternets exist to meet their members' communication needs -- to get people wired. Toasternets have become increasingly popular as demand for Internet services has outpaced the capabilities of commercial service providers." Gareth Bronwyn, also writing in Wired in 1993, defined them much more haphazardly, saying that they used "Cheap Internet routers made with old PCs" and coining the umbrella term "grunge computing." It is worthy of note that, prior to the 1992 privatization of the Internet via Al Gore's National Information Infrastructure plan, the operation of toasternets was not actually legal, since Internet connectivity was supplied to authorized parties (generally defense contractors and research universities) by, and at the expense of, the US Defense Department's Advanced Research Projects Agency, and toasternets extended access to the network beyond the parties authorized to use it. Many people also linked the name with a much more literal demonstration of SNMP-enabled toasters which had been connected to an Ethernet network by network management software vendor Epilogue, which caught the public's fancy at the time, and received some press coverage.

Worked examples

Example 1 — a first encounter with Toasternet

Start with the simplest possible case. Write down what Toasternet claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Toasternet before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Toasternet ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Toasternet

In research
Toasternet appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Toasternet in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Toasternet is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990s in Internet culture, 1991 in Internet culture, 1992 in Internet culture, so understanding it makes those chapters shorter.
In everyday life
Look for Toasternet outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Toasternet in simple terms?

Toasternets were an early-1990s instantiation of the decentralized Internet, featuring open-standards-based federated services, radical decentralization, ad-hoc routing and consisting of many small individual and collective networks rather than a cartel of large commercial Internet service provider…

Why does Toasternet matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Toasternet?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
