Overture Networks

Overture Networks 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 Overture Networks rather than just read about it. In short: Overture Networks was a company that designed, manufactured, and marketed networking and telecommunications equipment. It was "a leading developer of converged packet access platforms for Carrier Ethernet services." Overture was headquartered in the Research Triangle Park in North Carolina and also maintained offices in Westford, MA and Bangalore, India.

Key takeaways

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

Reference excerpt

Overture Networks was a company that designed, manufactured, and marketed networking and telecommunications equipment. It was "a leading developer of converged packet access platforms for Carrier Ethernet services." Overture was headquartered in the Research Triangle Park in North Carolina and also maintained offices in Westford, MA and Bangalore, India. Overture was a member of the Metro Ethernet Forum (MEF). It also held a TL 9000 certification which it received from the QuEST Forum in May 2007. In January 2016, Overture was acquired by telecommunications vendor ADVA Optical Networking.

History

In 2000, Overture was launched by co-founders Jeff Reedy and Prayson Pate to develop solutions designed to help service providers and network operators transition to an all-packet network. In December 2008, Overture Networks acquired Ceterus Networks, a Richardson, Texas-based manufacturer of Carrier Ethernet equipment and technologies for mobile backhaul. In March 2011, Overture merged with Hatteras Networks, the number one-ranked Ethernet over Copper market leader and manufacturer of Ethernet service delivery solutions for the Carrier Ethernet, Metro Ethernet, and DSLAM and mobile wireless backhaul markets. Post-merger, the unified company operated under the Overture Networks name until February 2012, when a rebranding initiative was announced. Marking the final integration of the two companies, Overture introduced a new logo, color palette, company blog, and tagline, "Overture - An Entrance to a Smarter Network", and informally dropped "Networks" from its name. Beginning in 2008, and continuing through 2009, 2010, and 2011, Overture was named as the number one provider of Ethernet over TDM (EoTDM) access circuits and Ethernet over bonded copper pair (EoC) platforms by analyst firm Heavy Reading. In September 2012, Overture appointed former Ciena Corporation Senior VP of Global Field Operations, General Manager of Global Government Solutions, and VP of Americas, Mike Aquino, as its new President and Chief Executive Officer (CEO).

Overture announced the company's entry into the software-defined networking (SDN) space in March 2012 with the launch of a new product, Ensemble OSA. Ensemble OSA is an open architecture based on open API standards like OpenFlow and has three layers, which may include Overture-developed components, as well as those developed by service providers or third-party vendors. Overture followed this with the release of the Overture 6500, the first Ensemble OSA-ready platform and the inaugural product in its Open Service Delivery Family product line. In January 2016, Overture was acquired by ADVA Optical Networking in a $35 million purchase which was reported to involve "an additional $5 million conditional 'earn-out' payment".

Products

Overture's products were generally used in the following solution categories: business services, mobile backhaul, Ethernet transport and infrastructure for speeds from 1 Mbit/s to 10 Gbit/s, and SDN. The company's products addressed these core applications using a range of access technologies including optical Ethernet, Ethernet over bonded copper, Ethernet over TDM/SONET/SDH/PDH, and multi-service Carrier Ethernet that supported TDM pseudo-wires and IP service aggregation using VLANs. Targeted to users such as competitive local exchange carriers, incumbent local exchange carriers, cable companies, and wholesale ISPs, its technologies were used in applications and settings like cloud computing, data center services, and mobile data services. Overture Network's products achieved MEF 9, 14, and 18 certifications.

Worked examples

Example 1 — a first encounter with Overture Networks

Start with the simplest possible case. Write down what Overture Networks 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 Overture Networks 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 Overture Networks 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 Overture Networks

In research: Overture Networks 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 Overture Networks 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: Overture Networks is common in secondary-school and first-year university syllabi. It links to neighbouring topics American companies established in 2000, Defunct computer companies of the United States, Defunct computer hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for Overture Networks 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.
