Reference excerpt

The Government Open Systems Interconnection Profile (GOSIP) was a specification that profiled open networking products for procurement by governments in the late 1980s and early 1990s.

Timeline 1988 - GOSIP: Government Open Systems Interconnection Profile published by CCTA, an agency of UK government 1988 - UK's CCTA commences work with France and West Germany on European Procurement Handbook (EPHOS) 1990 - The US specification requiring Open Systems Interconnection (OSI) protocols was first published as Federal Information Processing Standards document FIPS 146-1. The requirement for US Government vendors to demonstrate their support for this profile led them to join the formal interoperability and conformance testing for networking products, which had been done by industry professionals at the annual InterOp show since 1980. 1990 - Publication of European Procurement Handbook (EPHOS), intended to be a European GOSIP 1991 - 4th and final version of UK GOSIP released 1993 - Australia and New Zealand GOSIP Version 3 - 1993 Government Open Systems Interconnection Profile 1995 - FIPS 146-2 allowed "...other specifications based on open, voluntary standards such as those cited in paragraph 3 ("...such as those developed by the Internet Engineering Task Force (IETF)... and the International Telecommunications Union, Telecommunication Standardization Sector (ITU–T))" In practice, from 1995 interest in OSI implementations declined, and worldwide the deployment of standards-based networking services since have been predominantly based on the Internet protocol suite. However, the Defense Messaging System continued to be based on the OSI protocols X.400 and X.500, due to their integrated security capabilities.

Worked examples

Example 1 — a first encounter with Government Open Systems Interconnection Profile

Start with the simplest possible case. Write down what Government Open Systems Interconnection Profile 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 Government Open Systems Interconnection Profile 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 Government Open Systems Interconnection Profile 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 Government Open Systems Interconnection Profile

In research: Government Open Systems Interconnection Profile 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 Government Open Systems Interconnection Profile 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: Government Open Systems Interconnection Profile is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer standards, so understanding it makes those chapters shorter.
In everyday life: Look for Government Open Systems Interconnection Profile 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.
