Identifier-Locator Network Protocol

Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol rather than just read about it. In short: The Identifier-Locator Network Protocol (ILNP) is a network protocol that divides the two functions of network addresses, namely the identification of network endpoints, and assisting routing, by separating topological information from node identity. ILNP is backwards-compatible with existing Internet Protocol functions, and is incrementally deployable.

Key takeaways

Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Identifier-Locator Network Protocol from memory before moving on to harder problems.

Reference excerpt

The Identifier-Locator Network Protocol (ILNP) is a network protocol that divides the two functions of network addresses, namely the identification of network endpoints, and assisting routing, by separating topological information from node identity. ILNP is backwards-compatible with existing Internet Protocol functions, and is incrementally deployable. ILNP has an architecture with two different instantiations. ILNPv4 is ILNP engineered to work as a set of IPv4 extensions, while ILNPv6 has a set of IPv6 extensions. At least three independent open-source implementations of ILNPv6 exist. University of St Andrews (Scotland) has a prototype in Linux/x86 and FreeBSD/x86, while Tsinghua U. (China) has a prototype in Linux/x86. The University of St Andrews ILNP group is led by Prof. Saleem Bhatti. Other academics involved in continuing research include Ryo Yanagida, Samuel J. Ivey and Gregor Haywood. In February 2011, the IRTF Routing Research Group (RRG) Chairs recommended that the IETF standardise ILNP (RFC 6115) as the preferred evolutionary direction for IPv6.

Worked examples

Example 1 — a first encounter with Identifier-Locator Network Protocol

Start with the simplest possible case. Write down what Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol

In research: Identifier-Locator Network Protocol 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 Identifier-Locator Network Protocol 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: Identifier-Locator Network Protocol is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Internet architecture, Internet layer protocols, so understanding it makes those chapters shorter.
In everyday life: Look for Identifier-Locator Network Protocol 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.
