Ravenna (networking)

Ravenna (networking) 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 Ravenna (networking) rather than just read about it. In short: Ravenna is a technology for real-time transport of audio and other media data over IP networks. Ravenna was introduced on September 10, 2010 at the International Broadcasting Convention in Amsterdam.

Key takeaways

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

Reference excerpt

Ravenna is a technology for real-time transport of audio and other media data over IP networks. Ravenna was introduced on September 10, 2010 at the International Broadcasting Convention in Amsterdam. Ravenna can operate on most existing network infrastructures using standard networking technology. Performance and capacity scale with network performance. Ravenna is designed to match broadcasters' requirements for low latency, full signal transparency and high reliability. Fields of application include in-house signal distribution for broadcasting houses and other fixed installations, flexible setups at venues and live events, outside broadcasting support, and inter-studio links across wide area network links and production facilities.

Standard protocols Ravenna is an IP-based solution. As such, it is based on protocol levels at or above layer 3 of the OSI reference model. All protocols and mechanisms used within Ravenna are based on widely deployed and established standards:

Streaming is based on the well-established RTP / RTCP protocols with payload formats defined by various RFCs (i.e., RFC 3550, RFC 3551 et al.). Both unicast and multicast are supported on a per-stream basis. Stream management and connection is achieved through SDP or RTSP protocol. QoS is based on DiffServ mechanism Device configuration and discovery is executed through the use of DHCP and DNS services or zeroconf mechanisms. Low-level device configuration is accomplished through independent web services via HTTP protocol. Time synchronization is maintained via PTPv2 (IEEE 1588-2008). Stream redundancy is based on SMPTE ST 2022-7 standard.

Open technology Ravenna is an open-technology standard without a proprietary licensing policy. A first-draft version of the Ravenna specification is publicly available. The development is jointly executed within the RAVENNA Partner Group under the leadership of ALC NetworX GmbH, Munich. Current Ravenna partners include:

Standardization activities Ravenna contributed to the AES67 standardization efforts. Ravenna is compatible with AES67 and all relevant mechanisms, protocols and formats used for synchronization, transport and payload mandated by AES67 are fully supported. Ravenna contributed to the SMPTE 2110 standardization efforts. Ravenna is compatible with the audio parts SMPTE ST 2110-30 and -31.

Awards Ravenna was a recipient of a Technology & Engineering Emmy Award in 2020 for Development of Synchronized multi-channel uncompressed audio transport over IP Network.

Worked examples

Example 1 — a first encounter with Ravenna (networking)

Start with the simplest possible case. Write down what Ravenna (networking) 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 Ravenna (networking) 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 Ravenna (networking) 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 Ravenna (networking)

In research: Ravenna (networking) 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 Ravenna (networking) 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: Ravenna (networking) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio network protocols, Digital audio, so understanding it makes those chapters shorter.
In everyday life: Look for Ravenna (networking) 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.
