Packeteer

Packeteer 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 Packeteer rather than just read about it. In short: Packeteer, Inc., founded in 1996 by Robert Packer, Brett Galloway and Bob Luxenberg was an I.T. company based in Cupertino, California that was listed on the NASDAQ. Networking appliances focus on Application Traffic Management and optimization for wide area networks.

Key takeaways

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

Reference excerpt

Packeteer, Inc., founded in 1996 by Robert Packer, Brett Galloway and Bob Luxenberg was an I.T. company based in Cupertino, California that was listed on the NASDAQ. Networking appliances focus on Application Traffic Management and optimization for wide area networks. They held at least 40 patents for various network optimization methods. Packeteer was acquired by Blue Coat Systems in 2008. Packeteer was a contributing member of the Apdex Alliance. Their main product lines were:

PacketShaper (Traffic shaping, compression, TCP & HTTP acceleration, analysis, reporting) SkyX (TCP acceleration and compression, high latency link optimization) via the Mentat acquisition. iShared (WAFS and TCP acceleration, optimization, compression and caching) via the Tacit Networks acquisition. iShaper (Introduced: May 7, 2007. Combines PacketShaper and iShared technologies into a single appliance. Mobiliti software (data protection and link optimization for mobile business users. via the Tacit Networks acquisition. PolicyCenter (centrally manages the configuration, policy management, software distribution and adaptive response tracking of multi-unit deployments.)

History In 1996, Packeteer was founded. In 1999, Packeteer had an initial public offering on NASDAQ. In 2000, Packeteer acquired the company Workfire Technologies and released its AppCelera product based on the Internet Web Acceleration technology developed by Workfire. In 2004, Packeteer acquired the company Mentat, integrating its SkyX product into the Packeteer portfolio. In 2006, Packeteer acquired the company Tacit Networks, maker of the iShared and Mobiliti product lines. On April 21, 2008, Blue Coat System announced its intention to acquire Packeteer, Inc. On June 9, 2008, Packeteer, Inc. was acquired by Blue Coat Systems. which in 2016 was acquired by Symantec

Worked examples

Example 1 — a first encounter with Packeteer

Start with the simplest possible case. Write down what Packeteer 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 Packeteer 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 Packeteer 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 Packeteer

In research: Packeteer 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 Packeteer 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: Packeteer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1999 initial public offerings, 2008 mergers and acquisitions, American companies disestablished in 2008, so understanding it makes those chapters shorter.
In everyday life: Look for Packeteer 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 Packeteer in simple terms?

Why does Packeteer 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 Packeteer?

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.
