Hammer Technologies

Hammer Technologies 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 Hammer Technologies rather than just read about it. In short: Hammer Technologies (formerly known as Empirix) is an American company which designs and manufactures service assurance testing and monitoring equipment for IP-based communications networks such as Voice-over-Internet-Protocol (VoIP), IP Multimedia Subsystem (IMS)-based, next generation network and 5G wireless networks. Hammer is headquartered in Billerica, MA.

Key takeaways

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

Reference excerpt

Hammer Technologies (formerly known as Empirix) is an American company which designs and manufactures service assurance testing and monitoring equipment for IP-based communications networks such as Voice-over-Internet-Protocol (VoIP), IP Multimedia Subsystem (IMS)-based, next generation network and 5G wireless networks. Hammer is headquartered in Billerica, MA. On April 21, 2021, Hammer was acquired by Infovista, a Network automation software. Infovista, which is majority owned by Apax Partners France, today known as Seven2, said the deal “brings together a team of over 1,000 professionals serving over 1,700 customers across more than 150 countries, including 23 of the top 30 CSPs globally[1].”

History Hammer Technologies was founded by Steve Gladstone and John Kuenzig in late 1991. On September 6, 2000, the Hammer test technology was spun out of Teradyne and became Empirix Inc. Alex d'Arbeloff, co-founder of Teradyne, was appointed chairman of the board. On June 6, 2008, Empirix sold its e-TEST suite, a set of Web application testing products, to Oracle. The company then focused on developing products for testing and monitoring voice quality, contact center equipment and enterprise communications networks as well as carrier grade products for mobile, cable and telecom operators. The July 2010 acquisition of Mutina Technology S.p.A. expanded the company's offerings to cover Mobile Broadband (MBB), Next Generation Networks (NGN), SS7/SIGTRAN Signaling, VoD/IPTV, and IP Core for telecom and enterprise networks.[5] In November 2013, Empirix was acquired by Thoma Bravo LLC, a private equity partnership.[6] In April 2021, Empirix was acquired by Infovista. In October 2022, Empirix rebranded as Hammer. In January 2024, Hammer updated their legal entity name from Empirix Inc. to Hammer Technologies Inc.

Technology The company's core Hammer technology was designed to automate the testing of IP communications networks, applications and services. It models realistic user behavior and emulates the associated session-based, network traffic to measure real-time voice and video quality as well as the performance of the underlying infrastructure. This capability enables real-world load testing of pre-production VoIP, Unified Communications, IMS, NGN, mobile and other IP-based networks, applications and equipment. Hammer testing predicts both network traffic issues and the quality of the end-user, customer experience. Empirix adapted the Hammer test technology to provide on-going monitoring for in-production contact centers, enterprise communications systems as well as telecommunications, cable and mobile operators. Empirix has more than 30 patents and patents-pending.

Clients and partners Notable deployments of Empirix technology include China Mobile, lastminute.com, National Society for the Prevention of Cruelty to Children, Suddenlink, and Amtrak. Empirix's partners include Accenture, Avaya, Genesys, IBM, Cisco Systems, Intervoice, Nuance Communications, and Sonus.

Publications and research Empirix has published a book about testing and monitoring IMS subsystems and services entitled “Ensuring a Quality IMS Experience: A Practical Guide to Testing and Monitoring IP Multimedia Subsystem and Services.” In addition, the company has sponsored a DMG Consulting research study entitled, “Business As Usual? A Benchmarking Study of Disaster Recovery and Business Continuity for Contact Centers.” Empirix also sponsored the “Companies Unifying the Conversational Contact Center” survey and report created by Opus Research.

Worked examples

Example 1 — a first encounter with Hammer Technologies

Start with the simplest possible case. Write down what Hammer Technologies 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 Hammer Technologies 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 Hammer Technologies 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 Hammer Technologies

In research: Hammer Technologies 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 Hammer Technologies 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: Hammer Technologies is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies established in 1992, Networking companies of the United States, Software companies based in Massachusetts, so understanding it makes those chapters shorter.
In everyday life: Look for Hammer Technologies 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.
