SONiC (operating system)

SONiC (operating system) 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 SONiC (operating system) rather than just read about it. In short: The Software for Open Networking in the Cloud or alternatively abbreviated and stylized as SONiC, is a free and open source network operating system based on Linux. It was originally developed by Microsoft and the Open Compute Project.

Key takeaways

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

Reference excerpt

The Software for Open Networking in the Cloud or alternatively abbreviated and stylized as SONiC, is a free and open source network operating system based on Linux. It was originally developed by Microsoft and the Open Compute Project. In 2022, Microsoft ceded oversight of the project to the Linux Foundation, who will continue to work with the Open Compute Project for continued ecosystem and developer growth. SONiC includes the networking software components necessary for a fully functional L3 device and was designed to meet the requirements of a cloud data center. It allows cloud operators to share the same software stack across hardware from different switch vendors and works on over 100 different platforms. There are multiple companies offering enterprise service and support for SONiC.

Overview SONiC was developed and open sourced by Microsoft in 2016. The software decouples network software from the underlying hardware and is built on the Switch Abstraction Interface API. It runs on network switches and ASICs from multiple vendors. Notable supported network features include Border Gateway Protocol (BGP), remote direct memory access (RDMA), QoS, and various other Ethernet/IP technologies. Much of the protocol support is provided through inclusion of the FRRouting suite of routing daemons. The SONiC community includes cloud providers, service providers, and silicon and component suppliers, as well as networking hardware OEMs and ODMs. It has more than 850 members. The source code is licensed under a mix of open source licenses including the GNU General Public License and the Apache License, and is available on GitHub.

Worked examples

Example 1 — a first encounter with SONiC (operating system)

Start with the simplest possible case. Write down what SONiC (operating system) 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 SONiC (operating system) 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 SONiC (operating system) 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 SONiC (operating system)

In research: SONiC (operating system) 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 SONiC (operating system) 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: SONiC (operating system) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 software, Computing platforms, Debian-based distributions, so understanding it makes those chapters shorter.
In everyday life: Look for SONiC (operating system) 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.
